The present embodiments relate to a multi-layered woven product. More specifically, the present embodiments relate to a multi-layered woven product having a woven graphic image on at least one surface. The present embodiments additionally relate to using different types of weaving materials, weaving processes, and weaving patterns to impart different properties to a woven product.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter. The present invention is defined by the claims.
The present embodiments provide a woven element having a first plurality of warp threads extending in a first direction, the first plurality of warp threads being integrated into a first surface on a front side of the woven element. The woven element may further include a second plurality of warp threads extending in the first direction, the second plurality of warp threads being integrated into a second surface on a back side of the woven element. A first weft thread may extend in a second direction, where a first portion of the first weft thread is positioned in front of at least one warp thread of the first plurality of warp threads to form at least a portion of a graphic image on the front surface. A second portion of the first weft thread extends between the first plurality of warp threads and the second plurality of warp threads. A second weft thread of the woven element may include a reactive material.
The reactive material may be a thermoreactive material which may have a melting point lower than a melting point of the first weft thread.
The second weft thread may be exposed on the second surface on the back side of the woven element.
The second portion of the first weft thread may extend between the first plurality of warp threads and the second plurality of warp threads for a length extending across three consecutive warp threads of the first plurality of warp threads.
The first weft thread may include a third portion, the third portion being positioned behind at least one warp thread of the second plurality of warp threads to form a tie structure.
The second weft thread may have a backing portion extending the width of the woven element in the second direction, where at least 50% of the backing portion is positioned behind the second plurality of warp threads.
The second weft thread may include a larger denier than the denier of the first weft thread.
The woven element may have a pocket located between the first plurality of warp threads and the second plurality of warp threads.
Examples are described in detail below with reference to the attached drawing figures, wherein:
The subject matter of the present invention is described with specificity herein to meet statutory requirements. However, the description itself is not intended to limit the scope of this patent. Rather, the inventors have contemplated that the claimed subject matter might also be embodied in other ways, to include different steps or combinations of steps similar to the ones described in this document, in conjunction with other present or future technologies. Moreover, although the terms “step” and/or “block” might be used herein to connote different elements of methods employed, the terms should not be interpreted as implying any particular order among or between various steps herein disclosed unless and except when the order of individual steps is explicitly stated.
A finishing device may be provided which can dynamically finish one side of a woven product independently of a second side of the woven product. For example, a right side and a left side of a woven article may be finished independently of one another. The sides may be finished in a non-linear fashion, such as an organic geometry, which eliminates the need for at least some post-processing pattern cutting. Additionally, one or more finishing devices of the present embodiments can be dynamically (e.g., moveably) positioned in an interior portion of the woven product as it is being woven. Once positioned, the finishing devices may create apertures, pockets, and/or tunnels in the woven product and finish the edges of these creations. Interior finishing may occur in the direction of the warp and in the direction of the weft.

The loom 100 comprises a beam 110 that holds a set of warp threads 112 in tension. Although the term “thread” is used throughout this Specification for convenience sake, it is contemplated that the term “thread” may comprise any type of material (e.g., thread, yarn, string, braided material, extruded material, pulled material, spun material, and the like) formed from any substance including fabric materials, plastic materials, synthetic materials, metal materials, engineered materials, and the like. The loom also includes a first finishing device 116 and a second finishing device 118 that are positioned along the lateral edges of the loom 100 adjacent to a woven panel 124 (the woven panel 124 comprising warp threads interwoven with weft threads). While only two finishing devices are illustrated with respect to
The finishing devices 116 and 118 may be manually attached to a supporting frame of the loom (not shown). Alternatively, the finishing devices 116 and 118 may be positioned on one or more positioning mechanisms. The positioning mechanisms may be functional for moving the finishing devices in any direction and/or rotation. For example, the positioning mechanisms may be functional for moving one or more finishing devices in a vertical, horizontal, and/or pivoting manner. In an exemplary aspect, it is contemplated that the positioning mechanism may be comprised of rotating arms that bring the finishing devices 116 and 118 in and out of position on the loom 100 and move the finishing devices 116 and 118 laterally in the direction of the weft threads. The rotating arms may raise and lower the finishing devices 116 and 118 in order to operate on different panels/layers of the woven product. In other contemplated aspects, the positioning mechanism may implement one or more screw drives, conveyors, belts, rapiers, pneumatics, hydraulics, and the like.
With continued reference to
The finishing devices 116 and 118 may be programmed to dynamically move laterally in and out of the woven panel 124 (in the direction of the weft threads) as the woven panel 124 is being fed through the finishing devices 116 and 118. The lateral movement of the finishing devices 116 and 118 may be changed with each weft that has been woven. This dynamic movement allows the woven panel 124 to be generated with a finished edge in any possible shape—not just a linear shape—as the woven panel is formed. Vision and/or optical systems may be used in conjunction with the finishing devices 116 and 118 to monitor the lateral movements of the finishing devices 116 and 118 with respect to the woven panel 124.
In an exemplary aspect, it is contemplated that the finishing device operating on one or more wefts finishes the one or more wefts while allowing one or more warps not interwoven with the one or more wefts to maintain continuity. Stated differently, when an organic lateral edge is formed with wefts finished at a location inside the beam width, warp threads will extend from the finished edge toward the lateral edge of the beam. These warp threads may not be terminated until post-processing. The delay in terminating may allow for later woven wefts to utilize these wefts. However, it is also contemplated that warp threads outside the finished edge may be terminated at any point in the weaving process.
The finishing devices 116 and 118 may be programmably-coupled to a logic unit 114 by a wired or wireless connection. The logic unit 114 may execute a pattern program and instruct the finishing devices 116 and 118 based on the pattern program. Further, the logic unit 114 may also be programmably-coupled to the vision and/or optical systems of the finishing devices 116 and 118. The logic unit 114 may receive inputs from the vision and/or optical systems and, based on these inputs, instruct the finishing devices 116 and 118 to move laterally to a predetermined location based on the pattern program. Weaving and finishing the woven panel 124 according to the pattern program reduces the need to manually create the pattern shape after a panel has been woven.
The logic unit 114 may utilize one or more computer readable media having instructions maintained thereon for controlling one or more components. For example, it is contemplated that the logic unit 114 may have a processor and memory functional for executing instructions embodied on the computer readable media, such that by executing those instructions, one or more finishing devices, looms, vision systems, and the like may form a woven article with a finished edge. It is contemplated that a set of instructions identify a location at which a finishing device is to finish a woven article to produce a desired result. The instructions may be stored at the logic unit 114 and/or at a remote computing device, which communicates via a network connection (wired or wireless).
In addition to the logic unit 114, it is contemplated that the finishing mechanism and the positioning mechanism of a finishing device may have one or more computing mechanisms associated therewith. For example, the positioning mechanism may have a microcontroller associated that monitors the position and controls the drive system that operates the positioning mechanism. Similarly, the finishing mechanism may also have a microcontroller associated that controls one or more functions of the finisher. The finishing mechanism microcontroller may be responsible for ensuring components of the finishing mechanism are engaged. Together, a combination of logic unit, microcontrollers, and other components may work in concert to finish one or more edges, including internal edges, without direct human intervention.
The finishing devices 116 and 118 may be programmed to operate independently of each other. The result is a first edge 120 of the woven panel 124 that may have a different shape than a second edge 122 of the woven panel 124. As previously discussed, it is contemplated that the finishing device 116 and the finishing device 118 each have a positioning mechanism that operates independently of each other. As a result, each finishing device may move in a lateral direction that does not directly correlate with the other, when desired.
Turning now to
The loom 200 comprises a beam 210 that holds a set of warp threads 212 in tension. As previously discussed, the term “thread” is not limiting, but instead used for the convenience of this description. The loom 200 also comprises a support beam 214 mounted to the frame of the loom 200. A first set of finishing devices 216 and a second set of finishing devices 218 are attached to the support beam 214.
The first and second set of finishing devices 216 and 218 may be movable along the support beam 214 through, for example, the use of a screw drive or rollers, as previously discussed. The first and second set of finishing devices 216 and 218 may be able to rotate around the support beam 214 so that the functional aspects of the finishing devices 216 and 218 may be alternately aligned in the direction of the weft threads or the warp threads. Alternatively, one finishing device of the first set of finishing devices 216 may be oriented to operate in the direction of the weft threads (e.g., a tucker), and the second finishing device of the set of finishing devices 216 may be oriented to operate in the direction of the warp threads (e.g., a leno twist); the same holds true for the second set of finishing devices 218. The first and second set of finishing devices 216 and 218 may be able to pivot out of the way when not in use.
In another exemplary arrangement that is not depicted, the first set and the second set of finishing devices 216 and 218 may be mounted on movable arms that act to raise, lower, or laterally move the first and second set of finishing devices 216 and 218. Further, the first set of finishing devices 216 may be operated and moved independently of the second set of finishing devices 218. Although only two sets of finishing devices are shown in
As the loom 200 weaves the woven panel 226, the first and second set of finishing devices 216 and 218 cut and finish warp and/or weft threads to create apertures in the woven panel 226. For instance, as the loom 200 weaves the woven panel 226, the finishing devices 216 and 218 move laterally back and forth along a weft of the woven panel 226. The finishing devices 216 and 218 cut the weft threads and any warp threads 212 that are encountered and simultaneously finish the cut edges of the threads. The cut material may be finished by any of the methods outlined above with respect to
The sets of finishing devices 216 and 218 may be programmably-coupled to a logic unit 228 by a wired or wireless connection. The logic unit 228 may execute a pattern program and instruct the sets of finishing devices 216 and 218 based on the pattern program. Further, the logic unit 228 may also be programmably-coupled to the vision and/or optical systems of the sets of finishing devices 216 and 218. The logic unit 228 may receive inputs from the vision and/or optical systems and, based on these inputs, instruct the sets of finishing devices 216 and 218 to move laterally a predetermined distance based on the pattern program. Weaving and finishing the woven panel 226 according to the pattern program reduces the need to manually create the apertures after a panel has been woven. Further, the systems depicted in
The finishing devices discussed above with respect to
Apertures 320 may be created by one or multiple sets of interior finishing devices as discussed above with respect to
The woven product 300 also comprises an additional aperture 322 that may be constructed by one or more sets of finishing devices. The edges of the aperture 322 may be woven to panels above and below the aperture 322 to create a pocket in the woven product 300. Similarly, a portion of the edges of the aperture 322 may be woven to a panel below the aperture 322 to create an accessible pocket.
Further, it is contemplated that a warp thread separator may be used in conjunction with one or more components of a finishing device. For example, it is contemplated that a warp thread separator may be a wedge-like structure that is inserted between two warp threads that will eventually form the lateral edges of an internal aperture. By forcibly parting two traditionally parallel warp threads prior to (or contemporaneously with) the finishing of weft threads, an aperture may be formed that maintains the continuity of warp threads throughout the warp length of the woven article. It is contemplated that the finishing of the weft threads around each of the separated warp threads maintains the separated warp threads in a desired position, which may be in a non-parallel orientation.
In another exemplary aspect, it is contemplated that a series of finishing devices may be implemented to result in a desired aperture. For example, a leno warp twister may finish a plurality of warp threads in a number of substantially parallel twisted warps. Once the leno warp twister has twisted the warps, another finishing device may be implemented that cuts wefts between two substantially parallel twisted warps and proceeds to tuck each respective new weft end about a proper twisted warp. Further, it is contemplated that a warp separator may separate the two substantially parallel twisted warp groupings as the tucking of the wefts occurs.
A hubless leno warp twister is contemplated as being positioned on one or more internal (medial of the lateral-most warp threads) warp threads. In this example, when an aperture is desired at an internal position of the woven article, the hubless leno warp twister may be positioned on the corresponding warps that are positioned in the lateral direction of the aperture. In this example, the finishing device may include a tucker and a cutter that are functional for forming an aperture between the twisted warp groupings.
As depicted in
In the illustrated aspect of
As previously discussed, it is contemplated that a number of possible internal apertures may be formed using one or more finishing devices. For example,
The aperture 502 is formed by finishing (e.g., tucking) the weft threads that would otherwise cross a desired internal aperture. For example, the weft 510 is tucked around the warp 504 at a tuck 512. The finishing may occur during the weaving process (e.g., prior to packing by a comb, subsequent to packing by a comb) and/or the finishing may occur as a post-process procedure. The aperture 502 is formed with substantially linear perimeter edges. Other apertures discussed herein (e.g., an aperture 602 of
The moveable warp concept is exemplified in
It is contemplated that an aperture may have any shaped perimeter. For example, multiple curves having varied radii in various directions (e.g., different sized concave and convex-oriented curves) may be formed as a portion of the perimeter. Further, an aperture may be formed using any combination of techniques discussed herein. For example, a leno warp twist may be used to form one portion of the perimeter and an alternative technique may be used to form another portion of the perimeter, in an exemplary aspect.
As depicted in
In
Although the term “thread” is used for convenience sake, it is contemplated that the term “thread” may comprise any type of material (e.g., thread, yarn, webbing, braid, filaments, fibers), which may be formed from any type of substance including fabric materials, plastic materials, synthetic materials, metal materials, extruded materials, organic materials, engineered materials, and the like.
In some embodiments, and as described in detail below, the incorporation of multiple layers may allow for a woven article that can exhibit different characteristics at different surfaces. For example, one layer or surface resulting from coarser (e.g., larger denier) threads may have greater abrasion resistance and tensile strength characteristics, which may be better suited for an exterior surface of an article. Complementary, a layer or surface comprised of finer threads (i.e., smaller denier) may allow for a better skin contacting surface and therefore be suited for an interior article surface. Further yet, the finer threads may also be more suitable for forming woven graphical surfaces because a higher resolution may be achieved with the finer threads. As a result, the finer thread layer may be suitable for a location at which graphics are intended to be incorporated. These characteristics may result in a number of layer combinations that provide different characteristics (e.g., finer thread interior surface, a coarser thread internal layer for structure, and a finer thread exterior for graphical integration).
Turning to
A typical beater has a uniform dent that is selected based on the warp thread characteristics. However, in aspects contemplated herein, two or more warp threads may be packed simultaneously. In the illustrated example, there are four smaller dents 1308 between each larger dent 1306, which results in a 4:1 ratio of smaller denier warp threads to larger denier warp threads being packed simultaneously. This ratio may be adjusted based on the thread count of the various warp beams being simultaneously packed by the beater. In this example the finer warp thread may have a four times the thread count as the coarser warp thread. Any ratio and any ordering of dents (size of slot) are contemplated to effectively pack a weft when two or more warp materials are utilized. Other exemplary arrangements of beaters are contemplated.
The aspects of the present embodiments are also directed toward weaving using reactive materials.
At a block 1410, a product is woven with one material. The material may have reactive characteristics as outlined herein. Alternatively, the material may not have reactive characteristics. As will be discussed hereinafter, it is contemplated that an intermittent splicer may be utilized to insert a particular reactive material at a defined location within the woven article.
The weaving of a product with a material with reactive characteristics may include a material that prior to a reaction has a low stretch coefficient (e.g., a polymer-coated elastic material, where the polymer coating prevents the elastic properties of the core from being experienced). Following the reaction of the material, the underlying characteristics may be experienced. Therefore, traditional weaving techniques and equipment may be utilized that traditionally relies on a lower elasticity, but the resulting woven product may exhibit the elasticity property (at least in desired locations) by removing the restrictive sheath.
At a block 1412, selective portions of the woven product are treated or activated. In one aspect, activation or treatment may occur as the product is being woven. For instance, different activating devices such as a water jet, a heat device, a sintering laser, ultrasonic waves, chemicals, and the like may be applied to selective portions of the product while it is still on the loom. In another aspect, the activating mechanisms may be applied to selective portions of the product after weaving is complete and the product has been removed from the loom. In one example, selective portions of the product are treated with, for example, a mask. The mask may prevent the activation of the reactive material in defined locations that are desired to maintain the as-woven characteristics. Alternatively, the masked portion may determine the location at which the reactive material is activated.
Depending on the properties of the weaving material, activation of selective portions of the product may produce different functional or aesthetic properties. In one example, activation may cause selective portions of the product to dissolve or be eliminated thus producing apertures or open areas in the product. Activation may cause selective portions of the product to melt slightly and then reform to produce a solid portion in the product. As well, activation may cause selective portions of the product to change color. In another example, activation may cause selective portions of the product to be molded into certain shapes. Many other examples exist and are contemplated.
At a block 1414, further processing of the product may occur. For example, with respect to the treatment of selective portions of the product with a mask at block 1412, the mask may be reactive, and further processing may include activating the masked areas. Alternatively, the mask may be inert and be used to shield selective portions of the reactive materials from activation. In this case, the remainder of the product not covered by the mask may be activated using one or more of the activating devices discussed herein.
The first and second 3-D effectors 1514 and 1516 may be attached to one or more adjustable arms that act to move the 3-D effectors 1514 and 1516 laterally back and forth across the width of the panel and/or vertically to introduce changes in tension and excess in material. The first and second 3-D effectors 1514 and 1516 may also be attached to a support beam and moved by, for example, a screw drive or rollers. Further, the first and second 3-D effectors 1514 and 1516 may be pivoted out of the way when not needed. The contact head of the first and second 3-D effectors 1514 and 1516 may comprise any shape such as a cylinder, an ellipse, etc. The shape of the material contacting surface may determine the resulting 3-D form that results in the woven product. Although only two 3-D effectors are shown, it is contemplated that multiple effectors may be positioned across the width of the panel and at any location in the warp direction.
The first 3-D effector 1514 acts to increase the tension on the set of warp threads 1510 in select places along the width of the panel immediately prior to introducing the weft threads at the weft insertion point 1512. The weft threads are subsequently introduced at the weft insertion point 1512. The tension on the warp threads 1510 is maintained by the second 3-D effector 1516 as additional weft threads are inserted and the weft is packed. By maintaining increased tension on the set of warp threads 1510 during the insertion and packing of the weft threads, the deformity produced by the first and second 3-D effectors will be “locked” into place.
Further, it is contemplated that one or more 3-D effectors are positioned on the loom after the weft insertion point 1512, but prior to a loom beater that packs the weft. As such, the weft may be inserted in a substantially linear manner, as is typical, but before the weave is packed and “locked” into place, the 3-D effector increases the tension on one or more warps (and the inserted weft(s)). This increased tension may produce an excess in material at the location of the 3-D effector, which once the beater packs the weft, is maintained. This process may introduce deformations to an otherwise planar-type woven article. It is contemplated that the lateral position and the vertical position of one or more 3-D effectors may be dynamically altered during the weaving process, which may result in an organic three-dimensional form being introduced into the woven article.
While the 3-D effectors are depicted pressing in a common downward orientation, it is contemplated that a 3-D effector may exert a pressure in any direction at any location, and in any combination. Further, it is contemplated that any number and any position of a 3-D effector may be implemented.
The intermittent splicer 1614 may receive two or more materials such as material A 1610 and material B 1612 through one or more input ports. As used herein, a material received by the intermittent splicer 1614 may include, for example, yarn, thread, webbing, strands, braids, and the like. Further, it is contemplated that the material may be formed, at least in part, with organic substances (e.g., cotton, rubber), polymer-based substances (e.g., nylon, polyester, synthetic rubber), metallic-based substances (e.g., copper, silver, gold, aluminum), and other engineered materials (e.g., aramid synthetic fibers, carbon-fiber, fiber glass). The material is also contemplated having varied physical characteristics (as will be discussed hereinafter). For example, the material may have varied diameter, elasticity, abrasion resistance, chemical reactivity traits, tension modulus, tensile strength, moisture absorbance, and the like.
The material A 1610 and the material B 1612 may comprise different types of materials. For instance, the materials 1610 and 1612 may differ in diameter, density, color, functional properties, aesthetic properties, mode of manufacture (extrusion, spun, molded, etc.), treatments applied to the materials 1610 and 1612, and so on. Functional properties may comprise elasticity, stiffness, water solubility, thermoreactivity, chemical reactivity, and the like. Treatments applied to the materials 1610 and 1612 may comprise water proofing, wax coating, and/or applying coatings that impart a matte, luster, reflective, or shiny finish to the materials 1610 and 1612. Treatments may also comprise reactive coatings that may react with water, heat, chemicals, and the like. Additionally, it is contemplated that a multi-substance material is used. A multi-substance material may be a material having an outer sheath of a different substance than an interior core. In this example, the outer sheath may impart certain characteristics to the multi-substance material that differ from the internal core. For example, the internal core may have a high elasticity and the outer core may be a reactive coating that prevents the stretch of the multi-substance material. Therefore, as will be discussed hereinafter, it is contemplated that portions of the outer core may be selectively removed (e.g., reactively removed by chemical means or light, for example) to allow the properties of the inner core to be exhibited in those portions where the outer core has been removed. Alternative arrangements of a multi-substance material are contemplated (e.g., reactive core, reactive fibers intertwined with non-reactive fibers).
Returning to
The intermittent splicer 1614 receives material A 1610 and material B 1612. After being received by the intermittent splicer 1614, the materials may be fed through a measuring component (not shown) that measures predetermined distances of the materials 1610 and 1612. The measuring component may comprise a toggle wheel, a timing system that measures the rate at which the materials 1610 and 1612 are being received, a caliper system, and/or a vision or optical system to measure the predetermined distances/lengths of a material. After predetermined distances have been measured for material A 1610 and/or material B 1612, the intermittent splicer 1614 may be programmed to terminate material A 1610 and/or material B 1612 at predefined distances.
The intermittent splicer 1614 may use mechanical means such as a knife to terminate (e.g., cut) the materials 1610 and/or 1612. As well (or in the alternative), the intermittent splicer 1614 may use a laser, air, ultrasound, water, heat, chemicals, and the like to terminate the materials 1610 and/or 1612 at defined lengths. Therefore, it is contemplated that the intermittent splicer 1614 is functional to terminate a continuous run of material at an intermediate point in the run. For example, a material may be maintained on a spool that has several hundred feet of continuous material prepared to be fed through the intermittent splicer 1614. In this example, the intermittent splicer 1614 may terminate the material at any point along the length of the several hundred feet of continuous material (any number of times). As a result, any desired length of material may be used at any portion of a resulting combined material resulting from the intermittent splitter 1614.
The intermittent splicer 1614 may be mechanically operated by one or more mechanisms controlled by the logic unit 1624. For example, it is contemplated that the intermittent splicer 1614 may, without intervention from a human operator, terminate a material using an electro-mechanical mechanism (e.g., an actuator, pneumatic, hydraulic, motor) and/or the like. By controlling the terminating portion of the intermittent splicer 1614 by the logic unit 1624, an automated system may be implemented that once started, may not require intervention by a human to manufacture an article having a variety of materials strategically located in a common weft pass (or warp).
Once terminated, the materials 1610 and 1612 may be joined together by the intermittent splicer 1614 to create a combined material 1616. Traditional methods of joining materials 1610 and 1612 together such as fraying the ends of materials 1610 and 1612 and joining the frayed ends may be employed. For example, the materials to be joined may be comprised of a plurality of fibers that when separated (e.g., frayed) at each respective end may then be intermeshed together to form an effective bond between a first end of a first material and a first end of a second material. Additionally, other methods to join the materials 1610 and 1612 may be used such as ultrasonic fusing, lasering, welding, adhesive, heat, wrapping, tying, folding, and/or twisting. As a result, it is contemplated that the intermittent splicer 1614 may terminate a first material at a location along the length of the first material to form a first end and a second end relative to the location of termination. The first end, in this example, is proximate an output region of the intermittent splicer 1614 and the second end is proximate an input region of the intermittent splicer 1614. The first end, in this example, may be joined with a previous second end of a second material (e.g., also proximate the input portion of the intermittent splicer 1614). Further, the second end of the first material may then be joined with a newly created first end (e.g., proximate the output portion of the intermittent splicer 1614) of the second material. As will be discussed hereinafter, it is contemplated that any number of materials in any sequence may be joined.
The intermittent splicer 1614 may also be comprised of one or more maintainers. A maintainer may maintain one or more portions of the materials 1610 and/or 1612 in a desired position during a terminating process and/or during a joining process. For example, it is contemplated that a compression mechanism may hold the first material while terminating the first material. Further, it is contemplated that a maintainer may hold the combined material (e.g., first end of the first material) while being fused with a second end of the second material, even momentarily. However, it is also contemplated that the terminating and/or joining processes may be done on the fly (e.g., as the materials continue to pass through the intermittent splicer 1614).
The intermittent splicer 1614 may also comprise an expelling component (not shown) at the output portion. Once materials 1610 and 1612 have been combined to generate a combined material 1616, the expelling component expels the combined material 1616 from the intermittent splicer 1614. The expelling component may mechanically expel the combined material 1616 using rollers, conveyors, pulleys, and other mechanisms. The expelling component may also/alternatively use, for example, air and/or water to expel the combined material 1616 from the intermittent splicer 1614. Further, it is contemplated that the combined material may be expelled from the intermittent splicer 1614 by gravity and/or a pushing force exerted by an added material portion.
As can be seen from
It is contemplated that the intermittent splicer 1614 may be used in conjunction with any mechanism, such as a loom. Further, it is contemplated that the intermittent splicer 1614 may be used independently of other mechanisms. The intermittent splicer 1614 may also be implemented during any portion of a manufacturing process (e.g., forming the warp, passing the weft).
In an exemplary aspect, once expelled from the intermittent splicer 1614, the combined material 1616 is received by the feeding component 1618 via, for example, an input port. The feeding component 1618 may passively receive the combined material 1616 from the expelling component. The feeding component 1618 may also actively retrieve the combined material 1616 from the intermittent splicer 1614. For instance, the feeding component 1618 may generate a vacuum that draws the combined material 1616 into the feeding component 1618.
The feeding component 1618 is also configured to subsequently feed the combined material 1616 into the loom 1622. The combined material 1616 may be fed in to the loom 1622 as a weft. However, as previously discussed, the combined material may be used in connection with forming a warp beam. If the combined material 1616 is fed in as a weft, the feeding component 1618 may comprise a shuttle, one or more rapiers, an air jet, a water jet, and the like.
The feeding component 1618 may be associated with the dynamic tensioner 1620. The dynamic tensioner 1620 is configured to apply a variable amount of tension to the combined material 1616 as it is being fed into the loom 1622 by the feeding component 1618. The amount of tension applied may depend on the properties of the combined material 1616 as it is passing through the dynamic tensioner 1620. For instance, a smaller degree of tension may be applied to a more elastic segment of the combined material 1616 as compared to the amount of tension applied to a less elastic segment of the combined material 1616. Applying variable amounts of tension depending on the properties of the combined material 1616 helps to ensure that the combined material 1616 is fed smoothly into the loom 1622. Further, it is contemplated that the dynamic tensioner 1620 dynamically adjusts tension based, at least in part, on the characteristics of the combined material 1616 that has already passed through the dynamic tensioner 1620 for a particular weft pass. For example, if a non-elastic portion of material initially passes through the dynamic tensioner 1620, a greater amount of tension may be applied than when an elastic portion or even a subsequent non-elastic portion passes through the dynamic tensioner 1620 on a common weft pass.
The dynamic tensioner 1620 may apply tension by, for example, adjusting the diameter of the input port of the feeding component 1618. In instances where the feeding component 1618 is an air jet, tension may be adjusted by varying the amount of air used to propel the combined material 1616 into the loom 1622. Likewise, if the feeding component 1618 is a water jet, tension may be adjusted by varying the force of the water used to propel the combined material into the loom 1622. Further, it is contemplated that the dynamic tensioner 1620 may be formed from one or more compressive surfaces that apply varied levels of compressive forces on the combined material (e.g., rotating (or not) mated discs in a pulley-like orientation that have graduated mated surfaces that may be separated or closed to impart a desired level of compressive force to a multiple material passing through the graduated mated surfaces).
The dynamic tensioner 1620 may use a caliper-based system to determine when tension should be adjusted and how much the tension should be adjusted. For example, the caliper system may detect a thicker segment of the combined material 1616 and increase the tension applied to the combined material 1616. The dynamic tensioner 1620 may also use a vision/optical system to visually detect a transition from one segment of the combined material 1616 to an adjacent segment of the combined material 1616. The vision/optical system may also detect properties of the segment that determine how much tension should be applied; the tension may then be adjusted accordingly. For instance, the vision/optical system may be configured to detect a color or texture change from one segment to the next of the combined material 1616. Based on this change, the dynamic tensioner 1620 may adjust the tension on the combined material 1616. The dynamic tensioner 1620 may also use a timing system to determine when tension should be adjusted. For example, the combined material 1616 may be expelled from the intermittent splicer 1614 at a constant rate. The dynamic tensioner 1620 may adjust the tension depending on the rate of expulsion. The dynamic tensioner 1620 may also receive inputs from, for example, the logic unit 1624, and adjust the tension based on the received inputs. As a result, it is contemplated that one or more mechanisms may be implemented independently or in concert to adjust the dynamic tensioner 1620 to impart one or more desired characteristics to a resulting product at one or more desired locations.
In one aspect, the dynamic tensioner 1620 may be utilized as a quality control measure. For instance, the dynamic tensioner 1620 may apply an additional amount of tension to the combined material 1616 to adjust the combined material 1616 after it has been fed as a weft through a shed. This may be used to correct minor deviations in alignment of the weft with respect to the pattern that is being woven. For example, if a combined material has a particular portion intended to be placed at a particular location (e.g., at a particular location laterally along the warps), the dynamic tensioner 1620 may impart an elevated level of tension to allow the combined material to slightly extend a length at which it crosses a portion of the warp. Similarly, it is contemplated that the dynamic tensioner 1620 may impart a decreased level of tension to allow the combined material to slightly reduce a length affecting a location as portion crosses a particular warp. Additional mechanisms for adjusting a location of the combined material are contemplated that may not affect the stretch of the combined material (e.g., incorporating an excess portion at either (or both) ends of a weft pass to allow for lateral alignment by the feeding component 1618.
Although the dynamic tensioner 1620 is shown in
As mentioned, the feeding component 1618 feeds the combined material 1616 into the loom 1622 as either a warp or a weft. The loom 1622 may comprise any type of weaving structure. For example, the loom 1622 may comprise a single or multiple-beam loom, a Jacquard loom, a Dobby loom, and other looms known in the art.
The logic unit 1624 may be programmably-coupled to the intermittent splicer 1614, the feeding component 1618, the dynamic tensioner 1620, and/or the loom 1622 through a wireless or wired connection. The logic unit 1624 may be comprised of a processor and memory to perform one or more of the functions provided herein. Computer-readable media having instructions embodied thereon for performing one or more functions may be implemented with the logic unit 1624 to effectuate one or more of the functions. The logic unit 1624 may instruct these various components based on, for example, a pattern program to produce a woven product conforming to the pattern.
Further, the logic unit 1624 may also be programmably-coupled to the various vision/optical, timing, toggle wheel, and caliper-based systems associated with these components. The logic unit 1624 may, in one aspect, receive inputs from the various vision/optical, timing, toggle wheel, and caliper-based systems, and, based on these inputs and a programmed pattern/structure, instruct the intermittent splicer 1614 to terminate the material A 1610 or the material B 1612 at a predetermined location. Further, the logic unit 1624 may instruct the dynamic tensioner 1620 to apply a predetermined amount of tension to the combined material 1616 based on received inputs.
As provided herein, it is contemplated that the logic unit 1624 may be comprised of a computing device. Therefore, the logic unit 1624 may maintain one or more set of instructions useable by one or more components (e.g., intermittent splicer, loom, dynamic tensioner, Jacquard loom, measurement components, quality control components) to manufacture an article. The instructions may include logic capable of coordinating the automatic terminating and splicing of materials such that when inserted through a shed may be positioned in a defined location relative to the warp beam. Further, the logic may ensure the proper alignment and positioning of one or more portions of a multiple material element as integrated into an article.
The logic unit 1624 may store the instructions or may receive the instructions. For example, it is contemplated that the logic unit 1624 may be connected via a network to one or more computing devices that maintain parameters to complete a particular article. Upon receiving an indication to manufacture a particular article, the proper instructions (or portions thereof) are communicated to the logic unit 1624 for controlling one or more components to effectuate the manufacturing of the article. As such, it is contemplated that the logic unit 1624 may be responsible for ensuring that typically disparate components may operate in concert to automatically produce an article through the coordination of one or more functions of each of the components.
Turning now to
The feeding component 1718 may be dynamically programmed (by, for example, a logic unit) to deliver the weft to the receiving component 1720 at varying distances along the width of the weave instead of at the midway point of the weave. Further, the intermittent splicer 1716 may be programmed to terminate material 1712 and/or material 1714 and generate a combined material prior to the feeding component 1718 meeting the receiving component 1720 and transferring the combined material.
The weft threads 1812 are woven to produce an area 1818. The area 1818 may have different functional properties as compared to the remainder of the woven product 1800. For instance, the area 1818 may have a greater amount of stretch as compared to the remainder of the woven product 1800. In another example, the area 1818 may be composed of thermoreactive, and/or chemical reactive materials (e.g., water soluble). These materials may be treated with an appropriate agent (heat, water, and/or chemical) to eliminate the area 1818 or to further change the functional properties of the area 1818.
Additionally, the area 1818 may have different aesthetic properties as compared to the remainder of the woven product 1800. For instance, the area 1818 may be a different color than the remainder of the woven product 1800, or be composed of weft threads having a matte or shiny finish. The area 1818 may comprise a logo, graphic elements, geometric-shaped patterns, or organically-shaped patterns. Further, the area 1818 may be woven from weft threads having a different diameter as compared to the remainder of the woven product 1800. This may help to impart a three-dimensional aspect to the area 1818.
As described above, the system 1700 comprises a feeding component (in this case, a first rapier) that may be dynamically adjusted to deliver weft threads different distances along the width of the weave. A corresponding receiving component (a second rapier) may also be dynamically adjusted to receive the weft thread at the point of handoff from the feeding component. An intermittent splicer may generate a weft of combined materials prior to the receiving component receiving the weft thread from the feeding component. The result is the ability to produce a variety of geometric or organically-shaped patterns having different functional and/or aesthetic properties. For instance, area 1918 of the woven product 1900 is composed of weft threads having different properties from the weft threads that make up the area 1920. Like above with respect to
As depicted, it is contemplated that any combination of combined materials may be implemented at any location to form a product having organic-shaped characteristic portions imparted by selectively changing underlying materials of a weft. For example, the characteristic portions may have varied aesthetic and/or functional characteristics at specified locations. The ability to selectively impart desired characteristics intermittently in a weft pass (as opposed to having a uniform characteristic along a complete weft pass) provides increased control of a weaving process.
At a block 2206 a length of the first material is measured. The length may be measured to result in a particular length of the first material at a particular location within a resulting combined material. The measuring may be accomplished using mechanical mechanisms, timing mechanisms, optical mechanisms, and other techniques for measuring a length of a material. At a block 2208, a determination is made to terminate the first. The determination may be accomplished utilizing a logic unit that controls a terminator of the intermittent splicer. The determination may be made, at least in part, based on the measured length of the first material and a desired length to be used in a resulting combined material. Further, the logic unit may rely on a programmed pattern that coordinates the intermittent splicer and one or more manufacturing machines (e.g., loom, knitting machine, braider), which may be used in conjunction with the intermittent splicer. Once a determination to terminate is made at the block 2208, at a block 2210 the first material is terminated. The termination may be effected by a mechanical cutting, a chemical process, a heating process, an ultrasonic process, and/or the like.
At a block 2212, the first material and the second material are joined. The joining of the first and second materials may rely on a mechanical connection among elements (e.g., fibers) of each of the materials. Additionally, it is contemplated that other bonding techniques may be used to join the first material and the second material (e.g., welding, adhesive). Once the first material and the second material are joined, the resulting combined material may be incorporated into a product at a block 2214. For example, the resulting product may be formed using a number of machines and techniques, such as a loom for a woven article, a knitting machine for a knit article, a braiding machine for a braided article, and the like.
As previously discussed, a Jacquard-type machine may be implemented to raise and lower the appropriate warps at the appropriate time to form the first and the second layer. Other techniques are contemplated for forming the multi-layered woven article.
The woven element 2302 may have a tubular structure (e.g., a multi-layer or multi-panel structure) formed by positioning (e.g., “dropping”) some warp threads to one side of the fabric to form a second layer, as shown by woven element 2402 in
Turning to
A first weft thread 2422 may generally extend in a second direction corresponding to the weft direction of the weave, where the second direction is substantially perpendicular to the first direction (where the first direction corresponds to the warp direction). The first weft thread 2422 is depicted with a first portion 2424 positioned in front of at least one of the first warp threads 2414 (and in the depicted embodiment, in front of three consecutive first warp threads 2414). Accordingly, the first portion 2424 of the first weft thread 2422 may be visible on the front surface 2410 to contribute to a woven graphic image (e.g., graphic image 2313 of
Multiple weft threads may be inserted together in single weft insertion step such that these multiple weft threads follow the same path in the weft or form the same pick. This feature may increase the color coverage at selected areas of a graphic image and may provide textural and/or three-dimensional effects where multiple weft threads are placed on the front surface 2410 together. This feature may be accomplished by using any suitable multi-channeling technique, including (but not limited to) a double or triple channeling technique where more than one weft thread is inserted into the shed (i.e., the temporary separation between the warp threads during the weaving process) during the same weft-insertion step. Further, multiple weft threads may be intertwined or wrapped together prior to their insertion into the shed.
In some embodiments, the denier of the weft threads associated with the graphic image may be optimized for providing crisp, fine-resolution graphic detail. To achieve a high resolution in a region of a graphic, a relatively fine thread may be used in the weft. Thicker weft threads may include in regions of lower resolution or solid color. In one example, the denier of the weft threads associated with the graphic image may be approximately 50 denier with some threads potentially being 75 denier in regions of relatively low resolution or solid color. In some embodiments, even smaller deniers are used (e.g., 30 denier or smaller). The current embodiments are not limited to any specific denier for either the warp or weft threads, and multiple deniers may be used in a single woven element.
To achieve a high quality image, it may be desirable to achieve a relatively high thread density to thereby achieve a high number of image pixels. For example, when a loom is used, the end count (measured in warp ends per inch of fabric) may be maximized by utilizing the full capacity of warp ends available on the loom. The pick count (measured in weft threads per inch of fabric) may then be maximized by using the highest pick count possible without causing significant manufacturing complications due to the limitations of the weaving device. In exemplary embodiments, a 288 Satin Broadloom, or another suitable weaving device allowing for a relatively high thread density, may be used. In one non-limiting example (and as noted above), the end count of a multi-layered woven element is approximately 288 warp threads per inch, while the pick count is approximately 5000 weft threads per inch. It is contemplated that the density of the threads, both warp and weft, may vary at different locations within a single woven element and/or may vary between the layers of the multi-layered woven element.
When weaving a graphic image, the figure-forming threads (e.g., the weft threads exposed to the front surface of a woven element to form a graphic image) often have floating portions that are positioned behind the warp threads to be hidden from view in certain regions. Accordingly, the first weft thread 2422 may comprise a floating portion (e.g., a second portion 2426) that is positioned behind one or more of the first warp threads 2414. As shown, the second portion 2426 of the first weft thread 2422 extends between the first warp threads 2414 and the second warp threads 2416 such that an observer viewing the front surface 2410 would not readily see the second portion 2426. The second portion 2426 of the first weft thread 2422 may be selectively placed between the first warp threads 2414 and the second warp threads 2416 when the graphic image does not call for the visual effect associated with that thread. The first weft thread 2422 can extend any distance between the first warp threads 2414 and the second warp threads 2416. It is contemplated that the second portion 2426 of the first weft thread 2422 may extend continuously between the first warp threads 2414 and the second warp threads 2416 for a length extending across three consecutive first warp threads 2414, and in some instances may extend continuously for a much greater length (e.g., a length across ten, twenty, fifty, or even one hundred or more consecutive first warp threads 2414 as called for by the graphic image and other desired characteristics of the woven element).
The first weft thread 2422 may further have a third portion 2428 positioned behind at least one of the second warp threads 2416. This may provide a binding effect between the first layer 2418 and the second layer 2420. In other words, the third portion 2428 of the first weft thread 2422 may act as a tie-like structure (depicted as tie structure 2450) to maintain an aligned and integral relationship between the layers 2418 and 2420. In some embodiments, a separate weft thread may be included that primarily serves the purpose of binding the layers 2418 and 2420 together by alternating between the first and second warp threads 2414 and 2416.
As shown in
To illustrate, it is contemplated that the second weft thread 2430 may have a larger denier than the denier of the first weft thread 2422 to provide the woven element 2402 with suitable strength, rigidity, and the like, while the first weft thread 2422 provides a fine-resolution graphic image. Any suitable type of thread may be used in either the warp or the weft to achieve a variety of functional properties and/or visual effects. Types of threads that can be used include, but are not limited to, polyester threads (semi dull, full dull, Trilobal, etc.), rayon threads, nylon threads, heathered threads, space dyed threads, metallic threads (e.g., as manufactured by Lurex), monofilament threads, reflective threads, and burnout threads (i.e., dévore threads). In some embodiments, one or more threads may be made of or include a metal (e.g., gold, silver, copper, etc.) and may be configured to conduct electricity and/or heat.
Further, it contemplated that some or all of the threads in the warp or weft of the woven element 2402 could have properties that change in response to a stimulus (e.g., temperature, moisture, sweat, electrical current, magnetic field, light, etc.). In one example, and as described in detail below, the second weft thread 2430 may be made of a thermoreactive material responsive to heat. A thermoreactive material may be, for example, a thermopolymer or thermoplastic polymer that transitions from a solid state to a softened or liquid state when subjected to certain temperatures. Specific materials may include, but are not limited to, polyurethanes, polyesters, polyamides, polyolefins, and nylons. In some embodiments, the second weft thread 2430 may have a coating of a thermoreactive material and a core that is not formed of a thermoreactive material.
In another example, one or more threads may be used that change dimensionally with the presence of water. For example, at least a portion of the filaments or fibers in the threads may be formed of a moisture-absorptive polyester material, such as the various moisture-absorptive polyester materials manufactured by Teijin Fibers Limited of Japan. In some configurations, the threads may be entirely formed from moisture-absorptive materials. In other configurations, the threads may be formed from combinations of both moisture-absorptive materials and non-moisture-absorptive materials. For example, the threads may be formed from 50 percent moisture-absorptive polyester materials and 50 percent non-moisture-absorptive polyester materials. As a more specific example, the threads may be a semi-dull cationic polyester 50 percent and nylon 50 percent side-by-side conjugate thread with a 75 denier, 24 filament structure. Other relatively non-moisture-absorptive polymer fibers or filaments may also be utilized, such as rayon, nylon, and polyacrylic.
A substantial portion of the second weft thread 2430, depicted as backing portion 2432, may be positioned or dropped behind the second warp threads 2416. Advantageously, this may provide control over the surface characteristics of the back surface 2412 of the woven element 2402. In practice, many weft threads with different properties may be dropped behind the second warp threads 2416 to optimize the characteristics of the back surface 2412 for a wide variety of functions.
The tubular structure comprising two layers 2418 and 2420 may have a plurality of tie structures 2450. The tie structures may be placed at random or selected locations throughout the woven element 2402 to provide a uniform bond between layers. It is contemplated that the tie structures may be positioned only along a perimeter of the woven element (allowing for a pocket-like volume to be formed between the layers). In some embodiments, and referring back to
When a pocket 2352 is formed, the depicted apertures 2353 may be selectively cut away from one or more layers surrounding the pocket 2352. Alternatively, the apertures 2353 may be integrally formed into a layer of the woven element 2302 during the weaving process by using the techniques described above. In one embodiment, the apertures 2353 may be formed on both the front surface 2310 and the back surface 2312 of the woven element 2302. These apertures 2353 on opposite surfaces may be offset such that there is no direct channel or path through the entirety of the woven element 2302. The apertures 2353 may be included for their visual properties (e.g., a viewer may see the contrast between the layers when apertures are located on the front surface 2310) and/or their functional properties (e.g., they may act as perforations to add breathability to the fabric). The apertures may have any shape. In woven elements with more than two layers, it is contemplated that one or more apertures may be located on any of the layers, a subset of the layers, or all of the layers.
The woven element may have at least one thread formed of a reactive material, such as a water soluble material, an etchable material, a thermoreactive material, a moldable material, or any material that changes in response to temperature, moisture, sweat, electrical current, light, or other stimuli. In one example, referring to
The second weft thread 2430 of
In one application, the backing portion 2432 of the second weft thread 2430, which forms at least a portion of the back surface 2412, may be at least partially formed of a reactive material, such as a thermoreactive material. The backing portion 2432 may be exposed on the back surface 2412 of the woven element 2402, giving the back surface 2412 the ability to fuse or bond to another object when heated. It is contemplated that the exposed backing portion 2432 will form a substantial percentage of the second weft thread 2430. In some embodiments, the backing portion 2432 of the second weft thread 2430 may form anywhere from about 5% to about 99%, and often more than 50%, of the length of the second weft thread 2430 extending across the woven element 2402 (i.e., the width in the weft direction). In a more specific example, the backing portion 2432 may form about 80% of the length of the second weft thread 2430 extending across the woven element 2402. This percentage, along with the denier of the thread and the location in the woven element 2402, may be selected to optimize the characteristics of the back surface 2412 and may vary between different weft threads at different locations of the woven element 22402.
Referring to
The number of warp threads dropped to the back of the fabric may vary at different locations within a woven element. For example, a woven element may have one or more areas with a high resolution image and other areas where high-resolution is not needed. Here, the percentage of warp threads dropped to the back may be lower in the areas where high-resolution is desired and higher in the other areas. To illustrate, referring back to
As depicted in
Alternatively or in addition, an adhesive may be used to bond the woven element 2502 to the base element 2501. When an adhesive used, the surface characteristics of the back surface 2512 of the woven element 2502 may be optimized for suitable interaction with the adhesive. The adhesive may be applied with or without heat to the back surface 2512 and/or to the base element 2501. It may be desirable to print the adhesive to the back surface 2512 in a particular pattern without covering the entirety of the back surface 2512, as covering the entirety of the back surface 2512 may compromise certain characteristics (such as flexibility or breathability) of the woven element 2502. After the application of the adhesive, the back surface 2510 may be placed in direct contact with the base element 2501 to allow the adhesive to set.
In some embodiments, it may be preferable to use an adhesive that does not require heat during application. For example, in some configurations, a thermoreactive material is included in the woven element 2502 which may be activated at some point during the manufacturing process (either before or after bonding to the base element 2501) to produce a visual or functional effect separate from bonding the woven element 2502 to the base element 2501. In these configurations, the application of heat during a bonding step may inadvertently activate the thermoreactive material causing complications or compromising certain characteristics of the woven element 2502. It is also contemplated that the thermoreactive threads used for bonding may have a different melting point than other thermoreactive threads of the woven element 2502.
The back surface 2512 of the woven element 2502 may be configured to have a generally smooth, uniform structure suitable for being directly secured (e.g., in direct contact) to the base element 2501. In other words, at least a portion of the back surface 2512 may be configured to directly contact the base element 2501 without the placement of an intermediate object therebetween, such as a laminated backing layer or a coating. Currently, an intermediate object or layer is typically applied to a back surface of single-layer woven element incorporating a graphic image prior to bonding to a base element. This intermediate layer primarily is intended to cover loose and exposed floating threads resulting on the back side of the graphic image. This application of an intermediate object or layer, however, compromises certain characteristics of the woven element. For example, the application of an intermediate layer may increase the size, bulkiness, and weight of the woven element and may decrease its flexibility, elasticity, breathability, and susceptibility to wash puckering.
In the currently described embodiments, on the other hand, the multi-layer construction of the woven element 2502 allows for the capturing of any floating portions between the layers (layers 2418 and 2420 of
A multi-layered woven element in accordance with the described embodiments was tested under the American Society for Testing and Materials (“ASTM”) Standard Test Method for Air Permeability of Textile Fabrics (ASTM D737-04(2012)), and shown to have 22% more breathability as compared to a typical single layer woven element incorporating a graphic image and having an attached backing layer suitable for bonding. The same multi-layered woven element had 57.1% less weight than the comparable single layer woven element with the backing layer. As a non-limiting example, a multi-layered woven element in accordance with the described embodiments may have an air permeability as measured according to ASTM D737-04(2012) in a range of 1-15 cfm, or in a range of 2-11 cfm, or in a range of 9.5-10.5 cfm. As another non-limiting example, a multi-layered woven element in accordance with the described embodiments may have a weight less than 2 grams per meter squared (gsm), or less than 4 gsm, or in a range of 1-2 gsm.
Further, the present embodiments may be advantageous for reducing the degree of wash puckering generally experienced with woven elements having an intermediate layer attached thereto. Wash puckering is generally the result of the threads forming the woven element shrinking at a different rate than the material of an attached textile in response to heat and moisture applied during the washing process. The intermediate layer may restrict the ability of the threads of the woven element to self-adjust in response, therefore causing the woven element to buckle. One feature of the present embodiments is that the threads forming a back surface of the woven element are directly attached to the base textile layer, thereby allowing the threads the freedom to self-adjust in response to the above-described shrinkage differential to eliminate or substantially reduce wash puckering. Further, the multiple layers of the present embodiments may form a more stable woven structure as compared to a woven element with a single layer. The more stable woven structure may reduce the wash puckering internal to the woven element (e.g., the wash puckering resulting from differential shrinkage between the threads forming the woven element).
The woven element may be formed from any one of a variety of manufacturing processes, and any of the devices, processes, or features described above may be incorporated. In the embodiment depicted by
As depicted, the warp threads 2614 may be fed from a single warp beam 2662. Each warp thread 2614 may be controlled individually by the Jacquard needles 2664. The warp threads 2614 may selectively be manipulated by the Jacquard needles 2664 to be positioned either up or down when a weft thread is inserted into the shed. The weft thread may be inserted into the shed by any suitable insertion device (not shown), including a shuttle, a rapier, or the like.
The manipulation by the Jacquard needles 2664 during the weaving process may form the tubular structure with multiple layers, as described herein. The warp threads 2614 fed from the warp beam 2662 may be individually controlled to either be associated with the first layer 2418 or dropped to form the second layer 2420 (shown in
Referring to
The carrier device 2606 may transport the strip 2604 to a cutting device, such as a laser cutter 2640. Any other suitable cutting device may be used. The laser cutter 2640 may cut the woven element 2602 to shape. As shown in
The threads at the border of each cut may fuse together due to the heat provided by the laser, which may substantially prevent the woven element 2602 from unraveling or reduce a propensity of the woven element to unravel at the border. In exemplary embodiments, the carrier device 2606 is not severed by the laser cutter 2640 during the cutting step. Accordingly, after the cutting process, the waste material of the strip 2604 may be peeled away from the carrier device 2606 leaving only the woven element 2602 (and potentially also the shapes 2648). Alternatively, the woven element 2602 may be peeled away first, leaving the woven element 2602 isolated from the waste material of the strip 2604.
After the cutting step, the woven element 2602 may go through one or more post-processing steps 2646. The post-processing steps 2646 may include heat setting, chemical treating, coloring, washing, or the like. The post-processing steps 2646 may additionally or alternatively include cutting, splicing, or otherwise modifying the shape of the woven element 2602, which may involve cutting away or otherwise modifying only one layer (e.g., when a pocket 2352 is formed as shown in
