FABRIC CUTTING DEVICE WITH MODULAR CUTTING ASSEMBLY, AND METHODS OF ASSEMBLING AND OPERATING THEREOF

FIELD

Various embodiments are described herein that generally relate to devices and apparatus for cutting and stripping fabric, and in particular, to a fabric cutting device with a modular cutting assembly, and methods of assembling and operating thereof.

BACKGROUND

It is often necessary to cut larger pieces of fabric into smaller strips. This may allow, for example, smaller strips from different fabric pieces to be sewn (e.g., hooked/knitted) together. A challenge is that many fabric cutting devices do not enable fabric cutting into pre-set widths. In turn, non-uniform fabric strips are cut from the same or different cloths. Alternatively, fabric cutting devices, which do allow for pre-set cutting widths, do not flexibly accommodate changes to those widths.

SUMMARY OF VARIOUS EMBODIMENTS

According to one broad aspect, there is disclosed a fabric cutting device, comprising: a driving assembly comprising at least two rotatable members; and at least a pair of modular cutting assemblies removably coupled to each of the rotatable members, the modular cutting assemblies configured to cut fabric into one or more fabric strips, each assembly comprising a reconfigurable stacked arrangement of cutting and spacer component sets.

In some examples, each rotatable member rotates along a rotation axis, and further comprises a mounting portion for mounting a respective modular cutting assembly in a mounted position.

In some examples, in each modular cutting assembly, the components are stacked along an assembly axis, and in the mounted position, the assembly axis defines the rotation axis.

In some examples, the cutting and spacer component sets are arranged in an alternating configuration within each modular cutting assembly.

In some examples, the cutting component set includes cutting components with radial cutting edges for cutting through fabric, and the spacer component set includes one or more spacer components for spacing apart the cutting component sets.

In some examples, the modular cutting assemblies are in the mounted position, the component sets are arranged in opposing configuration as between the pair of cutting assemblies, such that along an alignment axis, a cutting component set of one assembly is aligned with a spacer component set of another assembly, to define a component set pair.

In some examples, in the mounted position, the assemblies are arranged in interleaving fashion such that the cutting component set of one assembly is positioned in the interspacing between the cutting component sets of another assembly.

In some examples, in the mounted position, one or more shear planes are defined, each shear plane defined along a lateral face of the cutting component set of one assembly and the lateral face of a cutting component set of the other assembly.

In some examples, the lateral faces directly abut to allow self-sharpening of the cutting components.

In some examples, the number of shear planes define the number of fabric strips the device cuts.

In some examples, the width of each fabric strip is defined by the axial spacing between adjacent shear planes.

In some examples, the number of components set pairs are adjustable to vary the number of cut fabric strips, and the width of each cutting component set is configurable to vary the width of each fabric strip.

In some examples, in each component set pair, the spacer component set is narrower than the cutting component set to provide a wear tolerance gap.

In some examples, the fabric cutting device is coupled to one or more of a cutting platform and a securing mechanism.

In some examples, the cutting platform provides a surface to lay the fabric during cutting, and the cutting platform extends between the pair of modular cutting assemblies.

In some examples, the securing mechanism secures the fabric cutting device to a mounting surface.

In some examples, the securing mechanism is adjustable and comprises a mounting bracket and a removable portion, the removable portion being vertically repositionable in relation to the mounting bracket.

In another broad aspect, there is provided a fabric cutting device kit, comprising: a fabric cutting device, comprising a driving assembly couplable to a pair of modular cutting assemblies, the driving assembly configured to cause rotation of the cutting assemblies to cut fabric into one or more fabric strips; one or more cutting components for cutting through fabric and having varying size widths; and one or more space components, wherein the one or more cutting and spacer components are stackable in a reconfigurable manner to define a modular cutting assembly.

In another broad aspect, there is provided a method for using the fabric cutting device kit, comprising: mounting, on a first rotatable member of the driving assembly, a first modular cutting assembly comprising a reconfigurable stacked arrangement of one or more cutting components and spacer components in alternating configuration; mounting, on a second rotatable member of the driving assembly, a second modular cutting assembly comprising a reconfigurable stacked arrangement of one or more cutting components and spacer components in alternating configuration; and operating the driving assembly to cut the fabric into one or more fabric strips.

In some examples, the method initially comprises dismounting one or more modular cutting assemblies prior to mounting the first and second modular cutting assembly.

DESCRIPTION OF VARIOUS EMBODIMENTS

Embodiments herein generally relate to a fabric cutting device with a modular cutting assembly, and methods of assembling and operating thereof.

I. General Overview

FIG. 1 shows an example fabric cutting device (102) with a modular cutting assembly, in accordance with disclosed embodiments. It is believed that the device (102) at least partially mitigates drawbacks associated with existing devices and apparatuses for cutting fabric.

As shown, the fabric cutting device (102) includes a number components, including: (i) at least one pair of modular cutting assemblies (104a), (104b); (ii) a driving assembly (106); and (iii) an actuator (110).

As explained below, the modular cutting assemblies (104a), (104b) are used to cut fabric into one or more strips. For instance, as exemplified in FIG. 2C, a large fabric piece (202) is inserted between the pair of cutting assembles (104), and is cut into fabric strips (204a), (204b).

The number of strips, as well as the physical dimensions of each strip (e.g., width dimensions), is determined by the configuration of the cutting assemblies (104). As discussed herein, the fabric cutting device (102) uses modular cutting assemblies (104a), (104b) that are re-configurable (e.g., by a user), to vary the number of cut strips, and their respective dimensions.

As shown in FIG. 1, the cutting assemblies (104a), (104b) are driven to rotate by the driving assembly (106). By rotating assemblies (104), the assemblies cut through fabric.

In some examples, the driving assembly (106) is housed within a housing enclosure (108) (FIG. 1). In an upright position, enclosure (108) includes an upper end (108a) and an opposed lower end (108b). Enclosure (108) also extends, along a housing axis (150), between a front end (108c) and a rear end (108d). It is understood, however, that the cutting device (102) is not limited to any particular orientation.

To enable use of the cutting device (102), the device may include an actuator (110). In the exemplified case, actuator (110) is a driving handle. The user can rotate the driving handle, e.g., around an axis parallel to the housing axis (150). In turn, this causes the driving assembly (106) to rotate the cutting assemblies (104), in order to cut through fabric.

In other examples, any other actuator (110) is used. For example, it is possible that the actuator (110) comprises a driving motor, and the fabric cutting device (102) is electrically powered. In these examples, the driving motor is disposed inside and/or outside housing (108). The driving motor can be driven, for example, by wired power or batteries (e.g., also disposed inside or outside housing (108)).

As best exemplified in FIGS. 2A-2C, the fabric cutting device (102) is optionally further coupled to one or more of: (i) a cutting platform (206), and (ii) a securing mechanism (208).

Cutting platform (206) provides a convenient surface to lay fabric (202) while its cut into strips (FIG. 2C). The cutting platform (202) may include a generally flat top plate (210) that accommodates placement of fabric. In some examples, the top plate (210) is removably coupled to the cutting platform (206).

As shown by example in FIG. 2D, the cutting platform (206) can extend between the two cutting assemblies (104a), (104b), e.g., parallel to housing axis (150). An aperture (252) is formed within the platform (208) to allow the cutting assemblies (104a), (104b) to interact (e.g., engage) with the fabric.

In the exemplified case, the top plate (210) accommodates right hand use of driving handle (110) (e.g., a right-hand top plate). For instance, as shown in FIG. 2E, the top plate (210) includes a guiding member (212), on one side of the assemblies (104). As the user rotates the driving handle clockwise (e.g., using their right hand), the fabric is guided by guide member (212) through the assemblies (104) (e.g., in the direction of “A” to “B”). A guiding tab (214) is disposed on the opposing side of assembles (104), and extends into the aperture (252). The guiding tab (214) is positioned to receive the cut fabric strips, and guide the strips back over the top plate (210).

In some examples, the top plate (210) can be replaced to accommodate left hand use of device (102). In this case, right hand plate (210) is replaced with a left-hand plate. In the left hand plate, the positions of the guiding member (212) and tab (214) are reversed, with respect to assemblies (104). In turn, the left-hand plate accommodates the reverse insertion of the fabric, in the direction of “B” to “A”, and the rotating of handle (110) in a counter-clockwise direction. In some examples, the guiding member (212) is removably coupled to the plate (210), such that it can be re-mounted in different positions, as between the right and left hand plates.

Optionally, to allow securing the fabric device (102) to other mounting structures, device (102) includes the securing mechanism (206) (FIG. 2A). In the exemplified case, the securing mechanism (208) is a clamp type structure (e.g., c-clamp). The clamp allows the user to affix the device (102), e.g., to a table (250) (FIG. 2B). In other examples, the securing mechanism (208) can have any other design known in the art.

In some examples, the cutting platform (206) and the securing mechanism (208) couple directly to the housing enclosure (108). For example, these components couple to a font end (108c) of housing enclosure (108).

II. Driving Assembly

As discussed, the driving assembly (106) is used for rotating the modular cutting assemblies (104a), (104b), thereby allowing the assemblies to cut through fabric.

FIGS. 3-6 exemplify a design for the driving assembly (106). It will be understood that the exemplified design is a non-limiting example for the driving assembly, and that other designs can also be used for rotating the cutting assemblies (104), as known to those skilled in the art.

As best exemplified in FIG. 5, the exemplified driving assembly (106) generally includes two rotating members (502a), (502b). Rotating members (502a), (502b) can comprise rotating driving axles, or the like.

While at least a portion of each rotating members (502a), (502b) can extend inside housing enclosure (108) (FIG. 4), for sake of explanation, FIG. 5 illustrates the driving assembly (106 with the housing enclosure (108) removed.

Each rotating member (502a), (502b) extends, along a respective extension axis (504a), (504b), and between a respective first end (508a), (508b) and a distal second end (510a), (510b).

The extension axes (504a), (504b) are oriented generally parallel to each other, and are otherwise spaced along an axis orthogonal to axes (504a), (504b). A length dimension (512a), (512b) is defined, respectively, for each rotating member (502a), (502b), between the first and seconds ends.

As exemplified in FIG. 5, in the upright position, the first rotating member (502a) is positioned over the second rotating member (502b). In other examples, the rotating members (502a), (502b) are disposed in any other manner, relative to each other.

To that end, a portion of each rotating member (502a), (502b) defines a mounting portion (520a), (520b), for mounting the cutting assemblies (104) thereto (FIGS. 5 and 6). As exemplified in FIG. 4, if a housing enclosure (108) is provided, the mounting portions (520) can extend outside of the enclosure (108).

In the exemplified case, the mounting portions (520) are proximal the rear member ends (510a), (510b) (FIG. 5). In other examples, any other portion(s) of the rotating members (502a), (502b) can define the mounting portions, insofar as both mounting portions (520a), (520b) are aligned along an axis orthogonal to the extension axes (504a), (504b). This ensures that the cutting assemblies (104) are aligned, along the same plane.

In some examples, the rotating member (502) includes limiting feature (522) (FIG. 5), which limit axial sliding of the cutting assembly (104) over a member (502) (FIG. 4). For instance, the mounting portions (520) may haves smaller diameters, and the limiting features (522) can comprise an expanded radial portion of the rotating members (502).

On the opposite end, a retention member (302) (FIG. 3) can be used to prevent the assembly (104) from slipping-off. For example, the retention member can comprise a bolt (302) or the like. In the exemplified case, the bolt (302) is threaded into a threaded end (524) of the rotating member (502) (FIG. 5).

In operation, each rotating member (502a), (502b) rotates about its extension axis (504). In this manner, each extension axis (504a), (504b) also defines a respective rotation axis. The rotation of members (502a), (502b) enables the complementary rotation of the cutting assemblies (104a), (104b), e.g., to cut through fabric. The rotation can be clockwise, or counterclockwise, depending on the desired design configuration.

Preferably, the rotating members (502) include a rotation-driving mechanism (514). This mechanism is used for rotating the members (502) synchronously together.

In the illustrated example (FIG. 5), the rotation-driving mechanism (514) is a gear assembly. Gear assembly includes gears (514a), (514b) disposed around each member (502). The gears (514) are disposed along any portion of the length of each member (502), e.g., proximal the first, front ends (508a), (508b), insofar as they are also generally aligned along an axis orthogonal to the extension axes (504a), (504b).

As exemplified, the gears (514) are positioned to be in threaded engagement (e.g., mating), such that rotation of one member (e.g., second member (502b)), automatically causes rotation of the other member (e.g., first member (502a)).

In other examples, rather than a gear assembly, any other rotation-driving mechanism (514) is used, and as known to the skilled artisan. Additionally, or in the alternative, the driving assembly (106) may not include a rotation-driving mechanism (514). For example, each rotating member (502) may be individually rotated.

Preferably, one or both of rotating members (502) includes a coupling interface (518). Coupling interface (518) allows an actuator (110) (e.g., driving handle, or motor axle), to couple to the assembly (FIG. 1). In this manner, the actuator (110) is used for rotating the rotating members (502).

In the illustrated example, the coupling interface (518) comprises a hole disposed on a front end (508a), of the lower rotating member (502b). The driving handle (110) (or motor axle) can couple to the hole (518). This allows actuator (110) to rotate the lower member (502b) which, in turn, causes the upper member (502a) to also rotate (e.g., by operation of the gear assembly (514)).

III. Cutting Assembly

The following is a discussion of a cutting assembly (104), that can be used alone or in conjunction with any other component of the fabric cutting device (102).

FIG. 7A exemplifies a modular cutting assembly (104), in accordance with the teachings herein.

Modular cutting assembly (104) can be mounted over a rotating member (502). For instance, the assembly (104) is mounted (e.g., slid) over a mounting portion (520), of a rotating member (502) (FIG. 6).

As exemplified, the cutting assembly (104) includes one or more: (i) cutting components (702), and (ii) spacer components (704).

The cutting and spacer components include respective apertures (750), which allow the components to mount (e.g., slide) over a rotating member (502) (FIG. 6), and along the respective extension axis (504) of each member.

In some examples, apertures (750) have a cross-sectional design (e.g., shape and size), complementary to the design of the corresponding rotating member (502), to allow a fitting engagement.

More generally, cutting components (702) are used to cut the fabric into one or more fabric strips. For example, cutting components (702) include one or more radial edges (780), along a cutting face, and sharpened to cut through fabric (e.g., bottom of FIG. 7A).

In the exemplified embodiment, the cutting components (702) comprise a generally annular design, as to make them annular cutting components (702). In other examples, any other desirable shape or design is used. Further, cutting components (702) may be formed of any suitable material (e.g., metal), and can further comprise one or more sub-components (e.g., adhered together).

Spacer components (704) are used for spacing apart the cutting components (702). As explained herein, the number of spacer components (704) (and/or their axial width), determines the width of fabric strips that are cut, using device (102).

As exemplified in FIG. 7A, in an assembled state, each cutting assembly (104) includes one or more cutting and spacer components (702), (704). The assembled stack extends along an assembly axis (708), between a first end (752a) and an opposed second end (752b). When assemblies are mounted to rotating members (502), the assembly axis (708) defines a rotation axis for each assembly.

In at least one example, the components are arranged (e.g., stacked) in a laterally abutting, and alternating configuration (FIG. 7A). That is, the spacer components (704) are arranged between cutting components (702), such as to space apart the cutting components (702).

In the exemplified embodiments, the assembly (104) includes alternating “sets” of cutting and spacer components (702), (704) (also referred to herein as “component sets”). As used herein, a “set” refers to one or more same-type components, which are axially aligned and stacked (e.g., along assembly axis (708)), and otherwise abutting.

For instance, in FIG. 7A, the assembly includes cutting component sets (712). Each set (712) includes one or more stacked cutting components (702) (e.g., (702a), (702b)). Similarly, each spacer component set (714) includes one or more spacer components, e.g., (704a), (704b). The advantages of this configuration are explained, further below.

As best exemplified in FIG. 8A, as between both cutting assembly (104), the component sets (712), (714) are also arranged in opposing, and alternating configuration.

For instance, when the assemblies are mounted—and viewed along an alignment axis (802) (FIG. 8A), which is orthogonal to the axis (504) of rotating members (502) (FIG. 4)—a cutting component set (712), in each assembly (104), is axially aligned with a spacer component set (714) of the other assembly.

As referred to herein, a pair of cutting and spacer component sets (712), (714)—aligned along alignment axis (802), or any parallel axis—defines a “component set pair” (804) (e.g., 712′, 714′) (see e.g., FIG. 8A).

In the mounted position, the assemblies (104) are further arranged in an interleaving fashion (FIG. 8A). For example, along alignment axis (802), or any parallel axis thereto—each cutting component set (712) of one assembly, is disposed in the interspacing between cutting component sets (712), of the opposing assembly (with the exception of some sets at either end of the assembly).

As a result of the interleaving, a number of shear planes (806) are defined (FIG. 8A). A shear plane (806) occurs in a plane parallel to axis (802), whereby: (i) a lateral face of a cutting component set (712a) of a first assembly (104), abuts and overlaps with (ii) a lateral face of a cutting component set (712b) of the second assembly (104).

To this end, the number of fabric strips cut by the device (102) is determined by the number of shear planes (806). This is because, it is at the shear planes (806) where the fabric is cut, i.e., as between radial edges of opposing cutting component sets (712a), (712b). A fabric strip is thereby formed between adjacent shear planes (806). The width of each fabric strip is based on the axial spacing (808) between consecutive or adjacent shear planes (806) (FIG. 8A).

In the exemplified embodiment of FIG. 8A, there are six shear planes (806) resulting in five cut fabric strips. In at least one example, the device (102) will generally include at least one shear plane (806). In some examples, the extent of the interleaving between assemblies (104)—which define the shear planes (806)—is based on the spacing between the assemblies (104), e.g., along axis (802).

As exemplified in FIG. 7B, in some examples, the spacer component sets (714) may include one or more gripping members. For instance, each spacer component set (714) can be surrounded by: (i) a first gripping element (756), directly engaged to the spacer component (704), and (ii) a second gripping element (758) radially and loosely surrounding the first gripping element (756). The first and second gripping elements (756), (758) are formed, for example, of rubber or the like. In some examples, only a single gripping element is used with each spacer set (714).

As exemplified in FIG. 8B, each component set pair (804) thereby includes a cutting set (712), axially aligned with a spacer set (714) with gripping members.

More generally, the use of gripping members offers a number of appreciated advantages to ensuring the quality of the strips of fabric being cut. These appreciated advantages include: (i) ensuring that the fabric feeds through the cutter sets (712), evenly and that the cutting action is continuous and slippage is minimized; (ii) ensuring that the fabric is held in place, and ensuring a constant width strip is cut; and (iii) anchoring the edges of the fabric strip as it is sheared between the cutting faces of the cutter sets (712), to ensure that the material is sheared effectively, and not otherwise stretched and torn apart between the cutters, which may result in a jagged cut edge and fabric dust that is otherwise undesirable.

It should be understood that the illustrated gripping members is only one example design, and that any other suitable design can be used to grip fabric between cutting assemblies (104).

IV. Tolerance Between Cutting and Spacer Sets

As best exemplified in FIG. 9, in some examples, the spacer sets (714) are configured to be narrower than the cutting sets (712), within a given set pair (804).

More generally, within a component set pair (804)—the width (808) of the cutter set (712), is greater than the width (810) of the spacer set (714). That is, the device includes cutter components (702) having a greater thickness than the spacer components (704).

This configuration ensures the direct contact of cutting faces, in opposing cutting sets (712) of opposing assemblies (104a), e.g., thereby defining the shear planes (806). In some examples, the direct friction contact between cutting faces, in this manner, allows the cutters to naturally self-sharpen during use of the fabric device (102).

As shown in FIG. 9, the use of narrower spacer sets (712) also defines a tolerance gap (902). Tolerance gap (902) is defined axially, between the spacer set (714) and adjacent cutter sets (712), of the same assembly (104). In some cases, this provides a degree of wear allowance, if the cutting face of a cutting component (702) wears out over time.

V. Modularity of Cutting Assembly

A unique feature of the disclosed fabric cutting device (102) is the modularity of the cutting assemblies (104). As exemplified in FIG. 6, the cutting assemblies (104) can be dismounted (e.g., slipped-off), their respective rotating members (104), in order to swap (e.g., vary or adjust or re-configure) the configuration of each cutting assembly (104).

The following is a discussion of various features that can be re-configured using the modular assemblies.

(i.) Number of Fabric Strips

In the exemplified embodiment of FIGS. 8A and 8B, the cutting assemblies (104) can cut fabric into five pieces. This is owing to the use of seven component set pairs (804), arranged to define six cutting shear planes (806).

In at least one example, the cutting assemblies (104a), (104b) are re-configurable to add or subtract the number of component set pairs (804), and thereby, re-configure the number of shear planes (806). In turn, this allows adapting or re-adapting the fabric cutting device (102) to vary the number of fabric strips that it can cut.

By way of example, FIG. 8C exemplifies cutting assemblies (104a), (104b) including six component set pairs (804), defining five shear planes (806). In turn, this configuration allows the fabric cutting device (102) to cut a single fabric piece into four separate strips.

In some examples, the component set pairs (804), on either end of the assemblies, may not necessarily include a spacer set (714), e.g., opposite the cutting set (712) (e.g., 714a1 and 714b3, in FIG. 8C). This is because, insofar as a cutting set (712) is present on either side, a shear plane (806) is already defined.

In at least one example, the initial cutting shear plane (806′) is optional.

(ii.) Fabric Strip Width

The fabric cutting device (102) can also be configured to cut different widths of fabric strips, concurrently.

In at least one example, the fabric cutting device (102) can cut different fabric widths, by stacking multiple cutting/spacer components together, in the same set.

By way of example, considering the set pair (712a₂) and (714b₂) (FIG. 8C)—as shown, this set pair includes: (i) a cutting set (712a₂) with three stacked cutting components (702), collectively defining an axial width (808c), and (ii) a spacer set (714b₂) with three stacked spacer components (704), collectively defining an axial width (812c). In this case, the fabric strip would have an axial width (808c), corresponding to the distance between adjacent shear planes (806).

By comparison, now considering the set pair (714a₃) and (712b₃)-this set pair includes: (i) a cutting set (712b₃) with two stacked cutting components (702), defining an axial width (808d), and (ii) a spacer set (714a₃) with two stacked spacer components (704), defining an axial width (810d). In this case, the fabric strip would have an axial width (808d).

As such, components can be stacked in different configurations, to define different component set widths. In at least one example, the device can allow mixing-and-matching cutting components (702) with width sizes of 3, 4 and/or 5 which, in turn, allows cutting fabric strip with widths in a range of anywhere between #3 to #16.

In other examples, rather than combining multiple components together-different widths of cutting and spacer components are used. For instance, in FIG. 8C, cutting set (712a₁) and spacer set (714b₁) include single components have a respective axial width (808a), (810a). Alternatively, cutting set (712b₁) and spacer set (714a₂) include single components have respective axial widths (808b), (810b).

(iii.) Cutting Assembly Kit

In at least one example, the fabric cutting device (102) is provided with a modular and reconfigurable cutting assembly kit. The kit can include various component set pairs (804) (FIGS. 8A and 8B), such that a user can add or subtract (e.g., configure and reconfigure) component pairs between both cutting assemblies (104a), (104b). In turn, the user can vary the number of fabric strips that are cut using the device (102). The kit can also include component set pairs (804) with different width dimensions to allow mixing-and-matching the fabric strips widths, as desired. More generally, it can include cutting components (702) with varying axial widths (808) (FIG. 8A).

In some examples, the kit includes different sizes of cutting components (702) (e.g., sizes 3, 4 and 5, as known in the art). As mentioned, this allow mixing-and-matching cutting components (702) with sizes 3, 4 and 5 in the same cutting component set (712) which, in turn, allows cutting fabric strip widths in a range of anywhere between #3 to #16. This allows each modular assembly to be formed of a reconfigurable stacked arrangement of cutting and spacer components.

VI. Tension Adjustment

A biasing member (304) (FIGS. 3 and 4) can be arranged between each retention member (302) and the cutting assembly (104).

The biasing member (304) operates to vary the axial force applied on a cutting assembly (104), by pushing/forcing the assembly (104) more tightly into the limiting member (522) (FIG. 5). In turn, in the mounted positions (FIGS. 8A, 8B)-the biasing member (304) applied to each assembly (104) causes interleaved cutting sets (712) to abut each other more tightly along shear planes (806). More generally, this provides a higher “clamping” force between the opposing cutting surfaces on the shear planes (806), and ensures that a gap is not produced by the force of the fabric being fed through the device, thus opening up the shear plane (806) to a gap that will counter the shearing action and produce undesired, intermittent or poor cutting results of the fabric strips.

To this end, the cutting assembly kit (described above) can also include different pairs of biasing members (304), that can be coupled to the rotating members (502). For example, different biasing members (304) can have different spring forces, to compress the cutting assembly stack to different degrees.

In some examples, the biasing member (304) and retention member (302) may be a single integrated component.

VII. Method of Assembling Modular Fabric Cutting Device

FIG. 10 shows an example method (1000) for assembling and operating a fabric cutting device (102), in accordance with the teaching herein.

At (1002), the existing cutting assemblies (104)—mounted on the rotating members (502)—are dismounted, e.g., partially or completely. More generally, this can involve dismounting one or more component set pairs (804), from each mounted assembly (104a), (104b) (FIGS. 8A, 8B).

In some examples, to dismount the assemblies, the retention members (302) (FIGS. 3 and 4), are initially decoupled from each rotating member (502a), (502b). This allows the cutting assemblies (104) to be accessed. If a biasing member (304) is also provided, this can also be dismounted.

If no cutting assemblies (104a), (104b) are already mounted on the cutting device (102), then act (1002) is disregarded.

At (1004), one or more new component set pairs (804) are mounted on each rotating member (502), e.g., on the respective mounting portion (520) (FIG. 6). In this manner, the configuration of each cutting assembly (104a), (104b) stack is modularly re-configured.

In some examples, the component set pairs (804) are selected from an available kit of component set pairs, as discussed above. For example, the user can select the number of component set pairs (804) to mount, based on the number of fabric strips they desire to cut. Otherwise, the user can select component set pairs with different width dimensions, to vary the strip width. More generally, different numbers of cutting components and spacer components can be mounted, as well, to vary the strip width (FIG. 8C-(712a₂), (714b₂), (714a₃), (712b₃)).

Once the component pairs (804) are mounted, the user can recouple the retention members (302) to each rotating member (502).

At (1006), the user can operate the fabric cutting device (102) to rotate the cutting assemblies (104), and thereby cut fabric. For instance, the user can operate the actuator (110) of the fabric cutting device (102), to cause the driving assembly (106) to rotate the cutting assemblies (104). For example, in FIG. 1, this can involve rotating the driving handle (110).

In at least one example, if biasing members (304) are provided (FIGS. 3 and 4), method (1000) can also involve dismounting and mounting biasing members (304). For example, between acts (1002) and (1004) the user can dismounted the existing pair of biasing members (304). The user can then select a new pair of biasing members (304), e.g., from a kit, based on the desired applied tension force. The user can then mount the new pair of biasing members (304), before recoupling the retention members (302).

VIII. Adjustable Securing Mechanism

FIGS. 11A-11D exemplify a portion of an adjustable securing mechanism (208), in accordance with teachings herein (see e.g., FIGS. 2A-2D).

As best exemplified in FIG. 11A, the securing mechanism (208) can include: (i) a mounting bracket (208a); and (ii) a removable portion (208b), which includes the engagement member (1150) (e.g., screw) that engages a mounting structure (250) (FIG. 2B).

As shown in FIG. 2A, when the mounting bracket (208a) is coupled to a bottom surface of the cutting platform (206), a C-clamp (or G-clamp) clamping configuration is formed.

As exemplified in FIGS. 11B-11D, the removable portion (208b) can couple in various manners relative to the mounting bracket (208a). More generally, disclosed embodiments allow adjusting the removable portion (208b) along the vertical and horizontal axis, relative to bracket (208a).

For instance, in an upright position—the design enables removable portion (208b) to be vertically re-positioned, relative to mounting bracket (208a) (FIG. 11C). In some examples, this allows the mechanism to accommodate different thicknesses of mounting structures (250) (FIG. 2B).

The design also enables horizontal re-positioning of the removable portion (208b), relative to bracket (208a) (FIG. 11D). For example, this allows adjusting the positioning of the fabric cutting device (102) relative to a mounting structure (250) (FIG. 2B), and/or allows a user to secure the device to different areas of the mounting structure.

The following is a more detailed discussion of the securing mechanism (208).

(i.) Mounting Bracket

Referring to FIG. 11A, in an upright position, bracket (208a) generally extends between an upper side (1102a) and lower side (1102b), along extension axis (1104a).

The upper side (1102a) can include a coupling interface (1106). Coupling interface (1106) allows bracket (208a) to couple (e.g., removably or fixedly), to the bottom of the cutting platform (206) (FIGS. 2A-2D).

To accommodate removable portion (208b), bracket (208a) includes a receiving aperture (1106), which extends along an axis orthogonal to extension axis (1104a). Aperture (1106) can extend part-way, or fully, through the width/thickness of bracket (208a).

To this end, bracket (208a) includes one or more sets of insert slots (1108a)-(1108d), formed integrally with aperture (1106). Insert slots (1108) are spaced apart along axis (1104a). As explained, the insert slots (1108a)-(1108d) allow the removable portion (208a) to be mounted in different vertical positions (FIG. 11C). In some examples, a pair of slots (1108) is provided along different vertical positions, and on either side of receiving aperture (1106).

In some examples, lined along each pair of slots (1108) are one or more locking tabs (1110). Locking tabs (1110) are spaced along an axis orthogonal to axis (1104a).

As provided herein, the locking tabs (1110) engage reciprocal grooves on the removable portion (208b). This allows re-positioning the removable portion (208b) inwardly and outwardly, e.g., along a horizontal plane (FIG. 11D).

In the exemplified case, each slot (1108) includes two locking tabs (1110). This facilitates two different inward/outward mounting positions for removable portion (208a). In other examples, any number of tabs (1110) can be provided in a given slot.

(ii.) Removable Portion

As also exemplified in FIG. 11A, the removable portion (208b) extends between a front end (1112a) and a rear end (1112b), along a length axis (1104b).

On the lateral faces, and extending from rear end (1112b) towards the front end (1112a) (e.g., along axis (1104b)) are one or more engagement ribs (1114a)-(1114d). Each lateral face can include a corresponding set of engagement ribs.

In the upright positions, the engagement ribs (1114) are spaced along a vertical axis, orthogonal to axis (1104b).

Accordingly, in a mounted position, the engagement ribs (1114a)—on either lateral face-slide through an aligned pair of insert slots (1108), in the bracket (208a). By sliding the ribs in and out of different slots (1108), the vertical positioning of the mounting portion is adjusted, relative to bracket (208a) (FIG. 11C).

One or more of the engagement ribs (1114) can also include locking grooves (1116). Locking grooves (1116) are spaced along axis (1104b).

In the mounted position, locking grooves (1116) engage with corresponding locking tabs (1110) in the mounting bracket (208a). This is used to adjust the depth positioning of the removable portion (208b) relative to the bracket (208a), as explained previously.

In some examples, a reverse configuration is used, whereby the mounting bracket (208a) includes the locking grooves, and the removable portion (208b) includes the locking tabs. In other cases, any other lock mechanism is used for engaging and readjusting the horizontal positioning of the removable portion relative to the bracket, as known in the art.
