DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS

Some detailed example embodiments are disclosed herein. However, specific structural and functional details disclosed herein are merely representative for purposes of describing example embodiments. Example embodiments may, however, be embodied in many alternate forms and should not be construed as limited to only the example embodiments set forth herein.

Accordingly, while example embodiments are capable of various modifications and alternative forms, example embodiments thereof are shown by way of example in the drawings and will herein be described in detail. It should be understood, however, that there is no intent to limit example embodiments to the particular forms disclosed, but to the contrary, example embodiments are to cover all modifications, equivalents, and alternatives falling within the scope of example embodiments. Like numbers refer to like elements throughout the description of the figures.

It should be understood that when an element or layer is referred to as being “on,” “connected to,” “coupled to,” or “covering” another element or layer, it may be directly on, connected to, coupled to, or covering the other element or layer or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly connected to,” or “directly coupled to” another element or layer, there are no intervening elements or layers present. Like numbers refer to like elements throughout the specification. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.

It should be understood that, although the terms first, second, third, etc. may be used herein to describe various elements, regions, layers and/or sections, these elements, regions, layers, and/or sections should not be limited by these terms. These terms are only used to distinguish one element, region, layer, or section from another region, layer, or section. Thus, a first element, component, region, layer, or section discussed below could be termed a second element, region, layer, or section without departing from the teachings of example embodiments.

Spatially relative terms (e.g., “beneath,” “below,” “lower,” “above,” “upper,” and the like) may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It should be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the term “below” may encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

The terminology used herein is for the purpose of describing various example embodiments only and is not intended to be limiting of example embodiments. As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise.

The control system 106 may process received sensor data to determine a weight of the formed pouch products and adjust the doser 140 or other portions of the apparatus 100 to ensure uniformity of formed pouch products.

The control system 106 according to one or more example embodiments may be implemented using hardware, or a combination of hardware and software. For example, hardware devices may be implemented using processing circuitry such as, but not limited to, a processor, Central Processing Unit (CPU), a controller, an arithmetic logic unit (ALU), a digital signal processor, a microcomputer, a field programmable gate array (FPGA), a System-on-Chip (SoC), a programmable logic unit, a microprocessor, or any other device capable of responding to and executing instructions in a defined manner.

For example, when a hardware device is a computer processing device (e.g., a processor, Central Processing Unit (CPU), a controller, an arithmetic logic unit (ALU), a digital signal processor, a microcomputer, a microprocessor, etc.), the computer processing device may be configured to carry out program code by performing arithmetical, logical, and input/output operations, according to the program code. Once the program code is loaded into a computer processing device, the computer processing device may be programmed to perform the program code, thereby transforming the computer processing device into a special purpose computer processing device. In a more specific example, when the program code is loaded into a processor, the processor becomes programmed to perform the program code and operations corresponding thereto, thereby transforming the processor into a special purpose processor.

According to one or more example embodiments, computer processing devices may be described as including various functional units that perform various operations and/or functions to increase the clarity of the description. However, computer processing devices are not intended to be limited to these functional units. For example, in one or more example embodiments, the various operations and/or functions of the functional units may be performed by other ones of the functional units. Further, the computer processing devices may perform the operations and/or functions of the various functional units without sub-dividing the operations and/or functions of the computer processing units into these various functional units.

The one or more storage devices may be tangible or non-transitory computer-readable storage media, such as random access memory (RAM), read only memory (ROM), a permanent mass storage device (such as a disk drive), solid state (e.g., NAND flash) device, and/or any other like data storage mechanism capable of storing and recording data. The one or more storage devices may be configured to store computer programs, program code, instructions, or some combination thereof, for one or more operating systems and/or for implementing the example embodiments described herein. The computer programs, program code, instructions, or some combination thereof, may also be loaded from a separate computer readable storage medium into the one or more storage devices and/or one or more computer processing devices using a drive mechanism. Such separate computer readable storage medium may include a Universal Serial Bus (USB) flash drive, a memory stick, a Blu-ray/DVD/CD-ROM drive, a memory card, and/or other like computer readable storage media. The computer programs, program code, instructions, or some combination thereof, may be loaded into the one or more storage devices and/or the one or more computer processing devices from a remote data storage device via a network interface, rather than via a local computer readable storage medium. Additionally, the computer programs, program code, instructions, or some combination thereof, may be loaded into the one or more storage devices and/or the one or more processors from a remote computing system that is configured to transfer and/or distribute the computer programs, program code, instructions, or some combination thereof, over a network. The remote computing system may transfer and/or distribute the computer programs, program code, instructions, or some combination thereof, via a wired interface, an air interface, and/or any other like medium.

The one or more hardware devices, the one or more storage devices, and/or the computer programs, program code, instructions, or some combination thereof, may be specially designed and constructed for the purposes of the example embodiments, or they may be known devices that are altered and/or modified for the purposes of example embodiments.

A hardware device, such as a computer processing device, may run an operating system (OS) and one or more software applications that run on the OS. The computer processing device also may access, store, manipulate, process, and create data in response to execution of the software. For simplicity, one or more example embodiments may be exemplified as one computer processing device; however, one skilled in the art will appreciate that a hardware device may include multiple processing elements and multiple types of processing elements. For example, a hardware device may include multiple processors or a processor and a controller. In addition, other processing configurations are possible, such as parallel processors.

Software may include a computer program, program code, instructions, or some combination thereof, for independently or collectively instructing or configuring a hardware device to operate as desired. The computer program and/or program code may include program or computer-readable instructions, software modules, data files, data structures, and/or the like, capable of being implemented by one or more hardware devices, such as one or more of the hardware devices mentioned above. Examples of program code include both machine code produced by a compiler and higher level program code that is executed using an interpreter.

Software and/or data may be embodied permanently or temporarily in any type of machine, element, physical or virtual equipment, or computer storage medium or device, capable of providing instructions or data to, or being interpreted by, a hardware device. The software also may be distributed over network coupled computer systems so that the software is stored and executed in a distributed fashion. In particular, for example, software and data may be stored by one or more computer readable recording mediums, including the tangible or non-transitory computer-readable storage media or memory 108 discussed herein.

FIGS. 15A, 15B, and 15C are illustration of the first material and/or the second material for use in the apparatus 100 according to at least one example embodiment.

As shown in FIGS. 15A, 15B, 15C, 15D, and 15E, the first material 1500 comprises a composite material 1510A and the second material 1500′ comprises a composite material 1510B. The composite material 1510A is the same as the composite material 1510B. The composite material 1510A, 1510B includes a first or elastic layer 1512 and a second or support layer 1514. In at least one example embodiment, the elastic layer 1512 comprises a sheet of non-woven elastomeric material and the support layer 1514 comprises a sheet of woven material. The elastic layer 1512 may be stacked with the support layer 1514. In at least some example embodiments, the elastic layer 1512 is disposed on top of the support layer 1514 and extends coextensive with the support layer 1514. In at least some other example embodiments, a support layer 1514 may be disposed on top of the elastic layer 1512 (see, e.g., the elastic layer 1541 and the support layer 1542 of FIGS. 15D-15E). At least a portion of the elastic layer 1512 may be coupled to the support layer 1514.

In at least some example embodiments, a first surface 1516 of the elastic layer 1512 may engage a first surface 1518 of the support layer 1514. In at least some example embodiments, the elastic layer 1512 is coupled to the support layer 1514 by physical characteristics of the elastic layer 1512 and the support layer 1514, for example, by adhesive friction. In at least one example embodiment, the elastic layer 1512 comprises polyurethane and the support layer comprises polypropylene.

The support layer 1514 may include a first portion 1520 and a second portion 1522. In at least some example embodiments, the second portion 1522 comprises a pair of second portions 1522, with the first portion 1520 being disposed between the pair of second portions 1522. In at least some example embodiments, the first portion 1520 and each of the pair of second portions 1522 is generally rectangular. The second portions 1522 may have substantially similar shapes and dimensions, and extend substantially parallel to one another. In at least some example embodiments, the support layer 1514 may be sized, shaped, and/or sub-divided (such as into the first and second portions 1520, 1522) to reduce or minimize interference of the support layer 1514 with regions of the elastic layer 1512 that will be involved in subsequent manufacturing processes.

In at least one example embodiment, boundaries between the first and second portions 1520, 1522 are at least partially defined by a plurality of perforations 1524 and the first portion 1520 is configured to be separated from the second portion 1522 at the plurality of perforations 1524. In at least some other example embodiments, boundaries between the first and second portions 1520, 1522 are separated by cuts or weak regions, such as thinner regions. Thus, the first and second portions 1520, 1522 may be configured to be separated from one another.

The second portion 1522 of the support layer 1514 may remain coupled to the elastic layer 1512 when the first portion 1520 is removed. In at least some example embodiments, the composite material 1510A, 1510B may be assembled, stored, and transported with the first and second portions 1520, 1522 remaining together. Accordingly, when the elastic and support layers 1512, 1514 are coextensive, the composite material 1510A, 1510B may be stored, such as on a roll or in stacks of sheets, without adjacent elastic layers 1512 substantially sticking to one another. In at least some other example embodiments, the first portion 1520 of the support layer 1514 may be removed from the second portion 1522 prior to storage and/or transport. Thus, the composite material 1510A, 1510B may further comprise an interleaf layer to reduce and/or prevent sticking between adjacent elastic layers 1512 (not shown). In still other example embodiments, the composite material is manufactured with a support layer that includes only second portions and is substantially free of a first portion (not shown).

FIG. 15B is a perspective view of the composite material of FIG. 15A having a portion of a support layer removed according to at least one example embodiment. FIG. 15C is a cross-sectional view of the composite material of FIG. 15B, taken at line 15C-15C.

In at least one example embodiment, the first portion 1520 of the support layer 1514 may be removed from the composite material 1510A, 1510B to create a composite material 1510A′, 1510B′, as shown in FIGS. 15B-15C. The composite material 1510A′, 1510B′ includes the elastic layer 1512 and a support layer 1514′. The support layer 1514′ includes the pair of second portions 1522, with the first portion 1520 (FIG. 15A) having been removed. Accordingly, a portion of the first surface 1516 of the elastic layer 1512 is exposed and free to interact with a product portion during a manufacturing process.

The composite material 1510A′, 1510B′ includes a first or product region 1526 and a second or apparatus region 1528. The product region 1526 comprises a portion of the elastic layer 1512 free from the support layer 1514′ (e.g., the portions where the pair of second portions 1522 remain). In some example embodiments, the apparatus region 1528 is configured to engage an apparatus (not shown) to facilitate conveyance of the composite material 1510A′, 1510B′ through the apparatus in a machine direction 1530. In some example embodiments, the presence of the support layer 1514′ in the apparatus region 1528 may maintain tensile strength of the composite material 1510A′, 1510B′ in the machine direction 1530 to facilitate conveyance of the composite material 1510A′, 1510B′ and/or may facilitate holding the composite material 1510A′, 1510B′ on an apparatus (e.g., on a top surface of the apparatus) during a manufacturing process. In at least some example embodiments, the composite material 1510A′, 1510B′ can be registered by and conveyed through the apparatus.

In the example embodiment shown in FIGS. 15B-15C, the apparatus region 1528 includes a first apparatus region 1528-1 and a second apparatus region 1528-2. The first and second apparatus regions 1528-1, 1528-2 may be disposed on opposite sides of the product region 1526. In at least one example embodiment, each of the product region 1526, the first apparatus region 1528-1, and the second apparatus region 1528-2 is substantially rectangular. The first and second apparatus regions 1528-1, 1528-2 may extend along opposing edges 1532 of the composite material 1510A′, 1510B′. In at least one example embodiment, the first and second apparatus regions 1528-1, 1528-2 extend continuously between a first end 1534 of the composite material 1510A′, 1510B′ and a second end 1536 of the composite material 1510A′, 1510B′ to maintain tensile strength of the composite material 1510A′, 1510B′ as it is conveyed through the apparatus in the machine direction 1530. In at least one example embodiment, the first and second apparatus regions 1528-1, 1528-2 extend substantially parallel to one another.

The product region 1526 is free to stretch and deform (such as in a direction perpendicular to the first surface 1516) to permit the performance of additional manufacturing steps, such as product placement, sealing of the elastic layer 1512 to itself or another elastic layer to form a pouch around the product, sealing the elastic layer 1512 around the product, and/or cutting or other methods of separation. The first and second apparatus regions 1528-1, 1528-2 may continue to engage the apparatus while other manufacturing steps are performed within the product region 1526.

FIG. 15D is an exploded perspective view of another composite material according to at least one example embodiment.

In at least one example embodiment, as shown in FIG. 15D, a composite material 1540A, 1540B includes a first or elastic layer 1541 and a second or support layer 1542. In at least one example embodiment, the elastic layer 1541 comprises a sheet of non-woven elastomeric material and the support layer 1542 comprises a sheet of woven material. In at least some example embodiments, the support layer 1542 is disposed on top of the elastic layer 1541 and extends coextensive with the elastic layer 1541.

In at least some example embodiments, a first surface 1543 of the support layer 1542 may engage a second surface 1544 of the elastic layer 1541. In at least some example embodiments, the elastic layer 1541 is coupled to the support layer 1542 by physical characteristics of the elastic layer 1541 and the support layer 1542, for example, by adhesive friction. In at least one example embodiment, the elastic layer 1541 comprises polyurethane and the support layer 1542 comprises polypropylene.

The support layer 1542 may include a first portion 1545 and a second portion 1546. In at least some example embodiments, the second portion 1546 comprises a pair of second portions 1546, with the first portion 1545 being disposed between the pair of second portions 1546. In at least some example embodiments, the first portion 1545 and each of the pair of second portions 1546 is generally rectangular. The second portions 1546 may have substantially similar shapes and dimensions, and extend substantially parallel to one another. In at least some example embodiments, the support layer 1546 may be sized, shaped, and/or sub-divided (such as into the first and second portions 1545, 1546) to reduce or minimize interference of the support layer 1546 with regions of the elastic layer 1545 that will be involved in subsequent manufacturing processes.

In at least one example embodiment, boundaries between the first and second portions 1545, 1546 are at least partially defined by a plurality of perforations 1547 and the first portion 1545 is configured to be separated from the second portions 1546 at the plurality of perforations 1547. In at least some example embodiments, boundaries between the first and second portions 1545, 1546 are separated by cuts or weak regions, such as thinner regions. Thus, the first and second portions 1545, 1546 may be configured to be separated from one another. In at least some example embodiments, the first and second portions 1545, 1546 are configured to be separated from one another during a manufacturing process.

The second portion 1546 of the support layer 1542 may remain coupled to the elastic layer 1541 when the first portion 1545 is removed. In at least some example embodiments, the composite material 1540A, 1540B may be assembled, stored, and transported with the first and second portions 1545, 1546 remaining together. Accordingly, when the elastic and support layers 1541, 1542 are coextensive, the composite material 1540 may be stored, such as on a roll or in stacks of sheets, without adjacent elastic layers 1541 substantially sticking to one another. In at least some other example embodiments, the first portion 1545 of the support layer 1542 may be removed from the second portion 1546 prior to storage and/or transport. Thus, the composite material 1540 may further comprise an interleaf layer to reduce and/or prevent sticking between adjacent elastic layers 1541 (not shown). In still other example embodiments, the composite material is manufactured with a support layer that includes only second portions and is substantially free of a first portion (not shown).

FIG. 1E is a cross-sectional view of the composite material of FIG. 1D, the composite material having a portion of a support layer removed.

In at least one example embodiment, the first portion 1545 of the support layer 1542 may be removed from the composite material 1540A, 1540B to create a composite material 1540A′, 1540B′, as shown in FIG. 1E. The composite material 1540A′, 1540B′ includes the elastic layer 1541 and a support layer 1542′. The support layer 1542′ includes the pair of second portions 1546, with the first portion 1545 (FIG. 15D) having been removed. Accordingly, a portion of the second surface 1544 of the elastic layer 1541 is exposed and free to interact with a product portion during a manufacturing process.

The composite material 1540A′, 1540B′ includes a first or product region 1548 and a second or apparatus region 1549. The product region 1548 comprises a portion of the elastic layer 1541 free from the support layer 1542′ (e.g., where the first portion 1545 of FIG. 15D has been removed). The apparatus region 1549 comprises the portions of the elastic layer 1541 that remain with the support layer 1542′ (e.g., the portions where the pair of second portions 1546 remain). In some embodiments, the apparatus region 1549 is configured to engage an apparatus (not shown) to facilitate conveyance of the composite material 1540A′, 1540B′ through the apparatus in a machine direction. In some embodiments, the presence of the support layer 1542′ in the apparatus region 1549 may maintain tensile strength of the composite material 1540A′, 1540B′ in the machine direction to facilitate conveyance of the composite material 1540A′, 1540B′ and/or may facilitate holding the composite material 1540A′, 1540B′ on an apparatus (e.g., on a top surface of the apparatus) during a manufacturing process. For example, the elastic layer 1541 is disposed between the support layer 1542′ and a surface of the apparatus. In at least some example embodiments, the composite material 1540′ can be registered by and conveyed through the apparatus.

In the example embodiment shown in FIG. 1E, the apparatus region 1549 includes a first apparatus region 1549-1 and a second apparatus region 1549-2. The first and second apparatus regions 1549-1, 1549-2 may be disposed on opposite sides of the product region 1548. In at least one example embodiment, each of the product region 1548, the first apparatus region 1549-1, and the second apparatus region 1549-2 is substantially rectangular. The first and second apparatus regions 1549-1, 1549-2 may extend along opposing edges of the composite material 1540A′, 1540B′. In at least one example embodiment, the first and second apparatus regions 1549-1, 1549-2 extend continuously between first and second ends of the composite material 1540A′, 1540B′ to maintain tensile strength of the composite material 1540A′, 1540B′ as it is conveyed through an apparatus. In at least one example embodiment, the first and second apparatus regions 1549-1, 1549-2 extend substantially parallel to one another.

The product region 1548 is free to stretch and deform (such as in a direction perpendicular to the first surface 1544) to permit the performance of additional manufacturing steps, such as product placement, sealing of the elastic layer 1541 to itself or to another elastic layer to form a pouch around the product, and/or cutting or other methods of separation. The first and second apparatus regions 1549-1, 1549-2 may continue to engage the apparatus while other manufacturing steps are performed within the product region 1548.

In at some example embodiments, the elastic layer is in the form of a sheet. The sheet may comprise an elastomer and be referred to as an “elastic layer.” The elastomer may include polypropylene, polyurethane, styrene, or any combination thereof. In at least one example embodiment, the elastic layer comprises polyurethane. In at least some example embodiments, the elastic layer may have a low basis weight and a high elongation, and therefore have a tendency to stretch and rebound when conveyed through a typical process absent a support layer.

In at least one example embodiment, the elastic layer comprises a nonwoven fabric. The nonwoven fabric may comprise a plurality of fibers. The fibers may comprise a polymer. In at least one example embodiment, the plurality of fibers comprise an elastomer. In at least one example embodiment, the fibers consist essentially of polyurethane. The plurality fibers may comprise melt-blown fibers, electro-spun fibers, centrifugal-force-spun fibers, or any combination thereof.

The support layer may also be referred to as a carrier or a scrim. In some example embodiments, the support layer is configured to maintain a minimum tensile strength of the composite material in the machine direction. In at least some example embodiments, the support layer is configured to maintain a minimum tensile strength of the composite material in both the machine direction and a cross direction substantially perpendicular to the machine direction. The support layer may include one or more of a sheet, such as a sheet including a woven material; a plurality of sheets; a web; a plurality of webs; an elongated support structure, such as a cord, a thread, a string, tape, a wire, or a polymeric strip; a plurality of elongated support structures; a sub-combination thereof, or a combination thereof.

In at least some example embodiments, the support layer is configured to facilitate holding a composite material on an apparatus. For example, at least a portion of the support layer may engage an apparatus, either directly or indirectly, to hold the composite material to the apparatus. In at least one example embodiment, the elastic layer is disposed between the apparatus and one or more portions of the support layer. A vacuum pulls the support layer to the apparatus, thereby holding the flexible layer between the support layer and the apparatus.

In at least some example embodiments, the support layer comprises a material that will not permanently bond to the elastic layer (see, e.g., FIGS. 15A-15C). Accordingly, the support layer is configured to be removably coupled or removably adhered to the elastic layer. In at least one example embodiment, the support layer comprises polyester, polypropylene, or a combination of polyester and polypropylene. In at least some other example embodiments, the support layer is permanently adhered to the elastic layer (see, e.g., FIGS. 5A-6).

In at least one example embodiment, the basis weight ranges from about 30 GSM to about 38 GSM, or optionally about 34 GSM.

In at least some example embodiments, the support layer has a lower machine direction grab elongation than the elastic layer. Accordingly, the elastic layer may have a first machine direction grab elongation and the support layer may have a second machine direction grab elongation that is lower than the first machine direction grab elongation. In at least some example embodiments, a ratio of first machine direction grab elongation to the second machine direction grab elongation may be greater than or equal to about 2, optionally greater than or equal to about 3, optionally greater than or equal to about 4, optionally greater than or equal to about 5, optionally greater than or equal to about 10, or optionally greater than or equal to about 15.

The support layer may generally have a higher machine-direction tensile strength than the elastic layer. Accordingly, the elastic layer may have a first tensile strength and the support layer may have a second tensile strength that is greater than the first tensile strength. In at least some example embodiments, the support layer has a tensile strength in the machine direction ranging from about 98 kilograms-force per meter width (kgf/M) to about 216 kgf/M, optionally about 100 kgf/M to about 215 kgf/M, optionally about 110 kgf/M to about 210 kgf/M, optionally about 120 kgf/M to about 200 kgf/M, optionally about 130 kgf/M to about 190 kgf/M, optionally about 140 kgf/M to about 180 kgf/M, optionally about 150 kgf/M to about 170 kgf/M, or optionally about 155 kgf/M to about 165 kgf/M.

No. ______ titled “CARRIER MATERIAL LAYER,” filed concurrently herewith (Atty. Docket Number 24000NV-000502-US), the entire contents of which is incorporated herein by reference.

In at least some example embodiments, the elastic layer is used to enclose a product portion, such as in a pouch formed from one or more sheets of elastic layers. In at least some example embodiments, the product portion is an oral product. The oral product may be a tobacco product, a nicotine product, or a non-tobacco product.

An oral tobacco product may include smokeless tobacco that is placed in the mouth and not combusted. Smokeless tobacco exists in various forms, such as chewing tobacco, moist smokeless tobacco, snus, dry snuff, etc. Chewing tobacco is coarsely divided tobacco leaf that is typically packaged in a large pouch-like package and used in a plug or twist. Moist smokeless tobacco is a moist, more finely divided tobacco that is provided in loose form or in pouch form and is typically packaged in round cans and used as a pinch or in a pouch placed in an adult tobacco consumer's mouth. Snus is a heat treated smokeless tobacco. Dry snuff is finely ground tobacco that is placed in the mouth or used nasally.

A nicotine product may include tobacco-derived nicotine, non-tobacco-derived nicotine, and/or nicotine derivative.

In operation, the apparatus 100 is configured to form pouch products and package the pouch products in containers as shown in FIGS. 16-29 and described herein. The pouch products include an outer layer formed of the elastic layer 1512 and an inner filling material, which may comprise tobacco or other plant material.

FIG. 16 is a top perspective view of a portion of the container feed system according to at least one example embodiment.

In operation, as shown in FIG. 16, the containers 900 are delivered to the conveyor 1425 of a container conveyor system 180 by the container infeed system 1430, which gravity feeds the containers 900 towards the conveyor 1425. As the conveyor 1425 progresses, one of the containers 900 slides from the container delivery chute 1600 to the space 1440 between adjacent ones of the cleats 1420 on the conveyor 1425. The container conveyor system 180 may be any suitable container system generally known to a person having ordinary skill in the art. The conveyor 1425 then moves forward, carrying the containers 900 towards the rotatable drum 125.

FIG. 17 is a partial front view of an apparatus for forming a pouch product including a first material extending through the first material distribution station according to at least one example embodiment. The first material 1500 and the second material 1500′ are described with respect to FIGS. 15A-15C.

In at least one example embodiment, as shown in FIG. 17, as the containers 900 (not shown in FIG. 17) move along the conveyor 1425, the first material 1500, which is on a roll 1700, is placed on the first roll holder 112 and then threaded through the first set of rollers 114 including the first tensioner 114A, the first dewrinkling roller 117, the first stripper plate 118, and to the first scrap roll holder 119. It should be noted that to initiate operation of the apparatus 100, the first material 1500 and the second material 1500′ are threaded through the rollers, like thread in a sewing machine, prior to operation.

During operation, the first material 1500 travels from the first roll holder 112 to the first receiving location 120. As the first material 1500 travels, the first material 1500 runs through the first tensioner 114A which may include the first tracking controller 116. The first tensioner 114A may include at least one tension sensing roller, as generally known to a person having ordinary skill in the art. The first tracking controller 116 and the first tensioner 114A are configured keep the first material 1500 on track and at a desired tension as the first material 1500 passes along the various rollers. The first tracking controller is configured to pivot a set of rollers around a center axis so as to maintain web tracking. The first tracking controller 116 is in constant movement so as to maintain the edge of the web within the target area of an edge sensor (not shown).

In at least one example embodiment, the first material 1500 then travels along the dewrinkling roller 117, which has a bowed (convex) surface that is configured to reduce and/or prevent wrinkles in the first material 1500.

Once the first material 1500 arrives at the first receiving location 120, portions of the first material 1500 are aligned with the rotatable drum 125, while the first portion 1520 of the first support layer 1514 is removed. Removal of the first portion 1520 along the perforations 1524 occurs as the first stripper plate 118 and remaining ones of the first set of rollers 114 roll up the first portion 1520, such that only the elastic layer 1512 and portions 1522 of the support layer 1514 of the first material 1500 remain at the first receiving location 120 and in contact with the rotatable drum 125. The motion of the rotatable drum 125 simultaneously pulls the elastic layer 1512 and the second portions 1522 of the support layer 1514 away from the removed portion 1520 thereby aiding in the removal of the first portion 1520. The first stripper plate 118 puts pressure along the first material 1500, and the first portion 1520 is pulled back over the first stripper plate 118 as the first scrap roll holder 119 and remaining ones of the first set of rollers 114 pull the portion 1520 from the elastic layer 1512 and the second portions 1522 of the support layer 1514.

In at least one example embodiment, at the first receiving location 120, the elastic layer 1512 and the second portions 1522 of the support layer 1514 are aligned with the rotatable drum 125, such that the elastic layer 1512 and the second portions 1522 of the support layer 1514 move with the rotatable drum 125 in a machine direction towards the dosing location 130. Thus, the elastic layer 1512 and the second portions 1522 of the support layer 1514 of the first material 1500 are conveyed through the apparatus 100 in the machine direction. The elastic layer 1512 and the second portions 1522 of the support layer 1514 of the first material 1500 includes the product region 1526 and the apparatus region 1528 (shown in FIGS. 15A-15C). The product region 1526 includes the elastic layer 1512, and the apparatus region 1528 includes the elastic layer 1512 and the support layer 1514′, which prevents stretching of the elastic layer 1512 as the composite material 1510A′ passes through the apparatus 100.

FIG. 18 is a perspective view of a first receiving location of the apparatus of FIG. 1 according to at least one example embodiment.

In at least one example embodiment, as shown in FIG. 18, the movement of the first material 1500 to the first receiving location 120 is shown in more detail. As shown, the first material 1500 moves along the first dewrinkling roller 117 to the first receiving location 120. At the first receiving location 120 along the path of the rotatable drum 125, the first material 1500 is brought into contact with a portion of the rotatable drum 125 while the first portion 1520 is pulled away from the elastic layer 1512 and the second portions 1522 by the first stripper plate 118 and the remaining rollers. As shown, the first portion 1520 is pulled in a direction substantially opposite to the direction in which the rotatable drum 125 rotates.

FIG. 19 is a perspective view of a first receiving location and a dosing location of the apparatus of FIG. 1 according to at least one example embodiment.

In at least one example embodiment, as shown in FIG. 19, an edge 2000 of the first stripper plate 118 abuts a portion of the rotatable drum 125 at the first receiving location 120. Once the first material 1500 aligns with the rotatable drum 125, the first portion 1520 of the support layer 1514 is pulled over the edge 2000 and the body of the first stripper plate 118 as the rotatable drum 125 rotates clockwise away from the first stripper plate 118. Substantially simultaneously, the removed first portion 1520 of the support layer 1514 is being pulled by the rollers and the first scrap roll holder 119 (shown in FIG. 17).

FIG. 20 is a top perspective view of the dosing location with the doser removed according to at least one example embodiment.

In at least one example embodiment, as shown in FIG. 20, the first material 1500 including the elastic layer 1512 and the second portions 1522 of the support layer 1514 moves along the rotatable drum 125 from the first receiving location 120 to the dosing location 130. The first edge 2000 of the first stripper plate 118 abuts the first material 1500 at the first receiving location 120. As the elastic layer 1512 and the second portions 1522 rotate with the rotatable drum 125, the removed first portion 1520 is pulled away from the elastic layer 1512 and the second portions 1522. The first portion 1520 is pulled in a direction opposite of the direction of rotation of the rotatable drum 125. The first portion 1520 extends over the first stripper plate 118.

Further, as shown, the elastic layer 1512 is semi-transparent such that the divots 400 along the rotatable drum 125 can be seen therethrough. As the rotatable drum 125 rotates, a vacuum is pulled via the vacuum source 410 so as to conform at least a portion of the first elastic layer 1512, which includes the first product region 1526, and the second portions 1522 to a surface of the apparatus 100. Thus, the vacuum pulls the elastic layer 1512 into each of the divots 400 prior to dosing by the doser 140.

In at least one example embodiment, the rotatable drum 125 may also include the grippers 710 (shown in FIG. 7), which may be air inlets at which the vacuum is communicated to the second portions 1522 and/or raised bumps that grip the first material 1500. In at least one example embodiment, when the grippers 710 include air inlets, the vacuum can be applied so as to pull and hold the first material 1500 against a surface of the rotatable drum 125.

After the elastic layer 1512 is pulled into the divots 400, the filler material is placed into the divots 400 on top of the elastic layer 1512 as will be discussed with respect to FIG. 22, and the rotatable drum 125 continues to rotate towards the second receiving location 150.

At the second receiving location 150, the second material 1500′ is aligned with the elastic layer 1512 and the second portions 1522 of the support layer 1514, such that the filler material is sandwiched between the elastic layer 1512 of the first material and the second material 1500′.

FIG. 21 is a top perspective view of the dosing location with the doser removed and a second receiving location according to at least one example embodiment.

In at least one example embodiment, as shown in FIG. 21, the second material 1500′ is aligned with the elastic layer 1512 and the second portions 1522 at the second receiving location 150, which is along the rotatable drum 125 as the rotatable drum 125 continuously rotates.

FIG. 22 is a partial front view of an apparatus for forming a pouch product including a first material roll extending through the first material distribution station and a second material roll extending through the second material distribution station according to at least one example embodiment.

In at least one example embodiment, as shown in FIG. 22, the elastic layer 1512 and the second portions 1522 of the support layer 1514 of the first material 1500 move along the rotatable drum 125 to the dosing location 130 after the elastic layer 1512 of the first material 1500 has been pulled into the divots 400 by vacuum as discussed with respect to FIG. 20.

At the dosing location 130, a desired amount of filler material is placed into each divot 400 on top of the first elastic layer 1512 by the doser 140. The doser 140 may be any suitable doser including a carousel style doser as discussed herein.

The rotatable drum 125 continues rotating from the dosing location 130 to the second receiving location 150, such that the filled divots 400 continue moving along the rotatable drum 125 towards the second receiving location 150.

At the second receiving location 150, the second material 1500′ is delivered to the rotatable drum 125 via the second roll holder 172, the second set of rollers 174 including the second tensioner 174A, and the second dewrinkling roller 177. The second material 1500′ is then aligned with the elastic layer 1512 and the second portions 1522 of the first material 1500, such that the filler material is sandwiched between the elastic layer 1512 of the first material 1500 and the second material 1500′.

At the second receiving location 150, as with the first material 1500, the first portion 1520 of the support layer 1514 of the second material 1500′ is removed as the second stripper plate 155 and second scrap roll holder 179 pull the first portion 1520′ away from the remaining second portions 1522′ along the perforations 1524. The first portion 1520′ is continuously rolled onto the second scrap roll holder 179 while the remaining second portions 1522′ of the second material 1500′ are aligned with the elastic layer 1512 and the second portions 1522 of the support layer 1514 of the first material 1500 as the rotatable drum 125 continuously rotates towards the cutting and sealing location 160.

FIG. 23 is a front perspective view showing the second material extending through the second material distribution station according to at least one example embodiment.

In at least one example embodiment, as shown in FIG. 23, the first portion 1520 of the second material 1500′ is pulled away from the remainder of the second material as the rotatable drum 125 rotates and the second stripper plate 155 presses against the second material. The second scrap roll holder 179 continuously rolls the removed first portion 1520 to aid in pulling the removed material from the remainder of the second material 1500′.

FIG. 24 is a side perspective view of the second receiving location and the cutting and sealing location according to at least one example embodiment.

In at least one example embodiment, as shown in FIG. 24, after the elastic layer 1512 and the remaining second portions 1522 of the first material 1500 and the second material 1500′ are aligned along the rotatable drum 125, the aligned materials move into contact with an edge 2400 of the second stripper plate 155. The edge 2400 abuts the rotatable drum 125 and the first portion 1520 of the second material 1500′ is pulled from the second portions 1522 of the second material 1500′ along the perforations 1524 (shown in FIGS. 15A-15C). The edge 2400 provides a point at which pressure is applied to the second material 1500′ as the first portion 1520 of the support layer 1514 is pulled and removed along the perforations 1524 in the support layer 1514 of the second material 1500′.

The remaining portions of the first material 1500 and the second material 1500′ continue to travel along the rotatable drum 125 to the cutting and sealing location 160, which may be at about a 4 o'clock position along the rotatable drum 125. As the rotatable drum 125 rotates clockwise, the heat knife assembly roller 505 rotates counterclockwise, such that the heat knives 510 align with respective ones of the divots 400 along the rotatable drum 125. The heat knives 510 are heated to a temperature sufficient to at least partially melt the first and second elastic layers so as to form a seal between the elastic layers of the first material 1500 and the second material 1500′. In at least one example embodiment, the heating is sufficient to at least partially cut the newly formed pouch product from the surrounding waste material simultaneous to the sealing.

FIG. 25 is a partial view of the apparatus of FIG. 1 showing the second receiving location and the cutting and sealing location according to at least one example embodiment.

In at least one example embodiment, as shown in FIG. 25, the first and second elastic layers are aligned and travel to the cutting and sealing location 160.

In at least one example embodiment, the apparatus 100 also includes a drum register 2500 configured to adjust a speed of rotation of the rotatable drum 125. The rotatable drum 125 is servo controlled to follow speed and position commands using motion move position cam instructions synchronized to follow a master virtual axis. Servo configuration allows each motor to know how to far to move over the course of one pouch, taking in account motor speed and powertrain setup (gear box ratios etc.). Speeds are therefore set in pouches/sec. The rotatable drum 125 has an attached disk with a small slot cut near outside perimeter. A homing sensor on each of the two disks detects the slots to provide a “Home” position. This home position is offset in software so as to provide accurate alignment of the two drums.

Further, as shown the heat knives 510 align with the divots 400 as the rotatable drum 125 rotates clockwise, and the heat knife assembly roller 505 rotates counterclockwise, and the first and second elastic layers pass therebetween.

FIG. 26A is a partial view of the apparatus of FIG. 1 showing an ejector station according to at least one example embodiment.

In at least one example embodiment, as shown in FIG. 26A, as the rotatable drum 125 continues to rotate past the cutting and sealing location 160, pouch products 2600, formed after being sealed and at least partially cut dangle from the surrounding waste materials 2602 as the rotatable drum 125 continuously rotates towards the ejection location 192.

As shown, the ejection location 192, includes the ejector assembly 905 including the ejector housing 908 defining an opening that catches the pouch products 2600 and aids in removal of the pouch products 2600 from the waste material 2602. The opening in the ejector housing 908 leads to at least one ejector 910. The edge of the ejector housing 908 may aid in scraping and/or pushing the pouch products 2600 from the waste material 2602 and into the ejectors 910. The ejectors 910 may be substantially tubular. The ejectors 910 include an outlet (not shown) that aligns with a respective one of the funnels 920 and a respective container as discussed herein, such that the pouch products 2600 are directed into containers for packaging. The pouch products 2600 are gravity fed through the ejectors 910, through the funnels 920, and into the respective containers.

FIG. 26B is a partial view of the apparatus of FIG. 1 showing an ejector station according to at least one example embodiment.

In at least one example embodiment, as shown in FIG. 26B, the waste removal system 190 further includes a waste roller 2605. As the rotatable drum 125 continues to rotate, the waste material 2602 moves over the waste roller 2605 and is then vacuumed up by the waste vacuum 1410 to remove the waste material 2602 from the area of the rotatable drum 125.

FIG. 27 is a partial view of the apparatus of FIG. 1 showing a tamping station according to at least one example embodiment.

In at least one example embodiment, after a desired number of pouch products 2600 are inserted into each container, the pouch products 2600 are tamped using the tamper 1000. The tamper 1000 is driven by a pneumatic cylinder with position feedback. After each container index, the tamper 1000 is commanded to extend and retract for a configured number of times and duration. Position switches confirm operation and ensure unit is out of the way before another container index can take place.

FIG. 28 is a lid distribution system for the apparatus of FIG. 1 according to at least one example embodiment.

In at least one example embodiment, as shown in FIG. 28, once the pouch products 2600 are in each container, a lid 2800 is placed on each container by a lid distribution system 2810, which may be any lid distribution system generally known to a person having ordinary skill in the art.

FIG. 29 is an enlarged view of a portion of the lid distribution system of FIG. 28 according to at least one example embodiment.

In at least one example embodiment, as shown in FIG. 29, each of the lids 2800 slides down a chute 2910 and is allowed to slide onto an open container. A flap 2900 applies pressure to the lid so ensure that the lid is pressed onto the container and forms a closed package.

FIG. 30 is a perspective view of a rotatable drum and ultrasonic rotary sealer and cutter according to at least one example embodiment.

In at least one example embodiment, as shown in FIG. 30, the rotatable drum 125 is generally the same as in FIG. 1. However, instead of the heat knife assembly, a rotary ultrasonic sealer and cutter 3000 is used to form seals between the elastic layers of material, and the rotatable drum 125 is modified to include ribs (shown in FIG. 32) around each divot.

In at least one example embodiment, the rotary ultrasonic sealer and cutter 3000 includes an ultrasonic roller or sonitrode roller 3010 and a housing 3020. The ultrasonic roller 3010 uses energy in the form of sinusoidal waves to soften the elastic material and seal multiple layers of the elastic material together. The energy wave amplitude or wave height may be adjusted as the power being applied is increased or decreased. The adjustment in power can be used to adjust the sealing based on mechanical strength and/or thickness of the material being sealed. For example, a polymer will soften at a specific rate depending on the mechanical properties of the base material until the polymer is sufficiently melted to create flow between layers being sealed so as to create a bond therebetween. The ultrasonic roller 3010 generates high frequency waves that vibrate the layers of material so as to generate heat and form a seal between the layers. Thus, the friction of vibration generates the heat to form the seal.

In at least one example embodiment, the housing 3020 of the rotary ultrasonic sealer and cutter 3000 is configured to pivot or slide so as to bring the ultrasonic roller 3010 into close proximity to the rotatable drum 125 or move the ultrasonic roller 3010 away from the rotatable drum 125 for maintenance purposes.

FIG. 31 is a top view of the rotatable drum and the ultrasonic rotary sealer and cutter of FIG. 30 according to at least one example embodiment.

In at least one example embodiment, as shown in FIG. 31, the ultrasonic roller 3010 has a generally smooth surface and comes into close proximity to a portion of the rotatable drum 125 so as to apply a specific amount of pressure to the mesh layers and drive flow between the mesh layers. Because the ultrasonic roller 3010 has a smooth surface, there is no need to align any specific portion of the ultrasonic roller 3010 with each of the divots 400. Further, the ultrasonic welding method may cut through any tobacco or non-metal material located in the sealing region so as to allow for one continuous seal to be formed thereby reducing and/or preventing any gaps where the material being encapsulated could escape from the pouch. Additionally, rotary ultrasonic sealer and cutter 3000 is configured to seal and cut the pouch from the mesh web substrate substantially simultaneously.

FIG. 32 is an enlarged view of a portion of the rotatable drum and the ultrasonic rotary sealer and cutter of FIG. 30 according to at least one example embodiment.

In at least one example embodiment, as shown in FIG. 32, ribs 3200 may surround each of the divots 400 of the rotatable drum 125. The ribs 3200 are configured to focus energy so as to form a seal between layers of material overlying the ribs 3200 as the ultrasonic roller 3010 passes over each of the ribs 3200.

In at least one example embodiment, as shown in FIG. 32, the rotary ultrasonic sealer and cutter 3000 includes an ultrasonic wave generator 3210, which may be in the ultrasonic roller 3010. In other example embodiments, the ultrasonic wave generator 3210 may be adjacent to the ultrasonic roller 3010. The ultrasonic wave generator 3210 may be any device configured to generate ultrasonic waves as known to a person having ordinary skill in the art.

Thus, an outer portion of each rib 3200 may be shorter than an inner portion of each rib 3200. Both the height H1 and the height H2 may range from about 0.5 mm to about 1.5 mm.

In at least one example embodiment, as shown in FIG. 35, each of the ribs 3200 may have an angled surface, such that a height H3 is less than a height H4.
