Abstract
Description
JIG SYSTEM, KNITTED COMPONENT AND METHOD OF SECURING A KNITTED COMPONENT TO A JIG FRAMEBACKGROUND
[0001] Textile manufacturing often involves production of an initial fabric, followed by various processing steps before final assembly. For example, uppers for an article of footwear may be manufactured by knitting, weaving or other methods, then processed by heating, pressing, or attaching components (e.g., laces, cables) .
[0002] To facilitate processing, textiles are commonly mounted on securing plates (jigs) . A fixed pattern of pins on the jig may be aligned with preset apertures in the textile to assist mounting. Conventional jig systems generally require a large number of pin attachment sites and result in scalloping between on the edge of the textile between pin attachment sites. These limitations increase labor time and costs, while reducing manufacturing efficiency and result in a scalloped edge of the textile, which is not usually desirable.BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Various aspects of the disclosure may be better understood by reference to the following detailed description. It is understood that features specifically described in the context of particular embodiments herein may also be implemented with other embodiments disclosed herein or other embodiments that may be reasonably anticipated by a person of skill in the art, within the scope and spirit of the disclosure.
[0014] At a high level, aspects herein are directed to jig systems, knitted components or other textiles, and methods for securing the knitted component or textile on a jig frame in a way that reduces scalloping on the knitted component or textile, thereby creating smoother edges. The smoother, cleaner edges provides for a more polished look and reduces or eliminates issues arising when joining a textile with un-intended scalloped edges to another component, such as a sole. For example, scalloping on the outer perimeter edges of an upper can require the sole to cover up a greater portion of the perimeter of the upper to prevent the edges from being visible. It can also make it more difficult to adhere the upper to the sole.
[0015] As such, aspects herein include a jig system, including a frame and one or more inserts for securing a textile to the frame. The jig frame includes one or more pin attachment sites at which the textile is secured to the frame via pin (s) . Additionally, the textile includes one or more tunnels along portions of an outer boundary, where the one or more tunnels receive jig inserts that, along with the pin attachment sites, collectively define an outer securing boundary for securing the textile on the jig frame. Some aspects include one or more jig inserts along an inner boundary of the textile, such as the boundary defining a throat region. The jig inserts, in conjunction with the pins attached to the pin attachment sites, help stabile the textile on the frame. Further, the jig inserts help apply tension along the edge of the textile to maintain a smooth or straight edge when the textile is secured to the jig for processing or additional manufacturing steps, thereby reducing scalloping or a wavy shape to the textile. The use of one or more jig inserts also replaces at least some of the pins and can be quicker to add and remove from the textile than the pins that are replaced, thereby improving manufacturing speed. A span (e.g., distance) between each pin can be optimized in order to keep a jig insert, such as a flexible one, from flexing inward under heat during post-knit processing and / or tension that is created when the textile shrinks during post-knit processing.
[0016] In some aspects, the tunnel in the textile is an integrally formed tunnel. For example, the textile may be a knitted component with a first knit layer and a second knit layer, with a pocket between the first knit layer and the second knit layer. The tunnel may have a relatively narrow width so that the tunnel can accommodate an insert without being visible above a biteline when the textile is secured to a sole or without having a greater amount of the textile having to extend over the sole than what is otherwise necessary. In some examples, the tunnel has a first edge and a second edge, and a width between the first and second edges is no greater than ten knit stitches.
[0017] The textile secured to the jig system as disclosed herein may be formed into an article, such as an article of footwear or an article of apparel. For example, the textile may form at least part of an upper for an article of footwear.
[0018] As used herein, the term “article of footwear” generally includes an upper and a sole structure. The upper is secured to the sole structure and forms a void within the article of footwear for comfortably and securely receiving a foot. As used herein, the term “upper” refers to a footwear component that extends over the instep and toe areas of the foot, along the medial and lateral sides of the foot, and around the heel area of the foot to form a void for receiving a wearer’s foot. Illustrative, non-limiting examples of uppers may include uppers incorporated into a basketball shoe, a biking shoe, a cross-training shoe, a global football (soccer) shoe, an American football shoe, a bowling shoe, a golf shoe, a hiking shoe, a ski or snowboarding boot, a tennis shoe, a running shoe, and a walking shoe. Further, in other aspects, the upper may also be incorporated into a non-athletic shoe, such as a dress shoe, a loafer, and a sandal. Accordingly, the concepts disclosed with respect to articles of footwear apply to a wide variety of footwear types.
[0019] Various terms are used to describe areas of articles of footwear and uppers. For reference purposes, an article of footwear and an upper may be divided into three general regions: a forefoot region, a midfoot region, and a heel region. The forefoot region generally includes portions of the component corresponding with the toes and the joints connecting the metatarsals with the phalanges. The midfoot region generally includes portions of the component corresponding with an arch area of the foot. The heel region generally corresponds with rear portions of the foot, including the calcaneus bone. The respective component may further be divided into a lateral side and a medial side which extend through each of the toe, midfoot, and heel regions. More particularly, the lateral side corresponds with an outside area of the foot (e.g., the surface that faces away from the other foot) , and the medial side corresponds with an inside area of the foot (e.g., the surface that faces toward the other foot) . The regions and sides discussed are not intended to demarcate precise areas but, rather, are intended to represent general areas to aid in the following discussion.
[0020] In various aspects, an upper disclosed herein is formed from a textile. As used herein, the terms “textile” or “textile component” include, for example, knitted, woven, and nonwoven fabrics or cloth.
[0021] The term “knitted component” or “knitted upper” refers to a textile piece that is formed from at least one yarn that is manipulated (e.g., with a knitting machine) to form a plurality of intermeshed loops that define courses and wales. The term “course, ” as used herein, refers to a predominantly horizontal row of knit loops (in an upright textile as knit) that are produced by adjacent needles during the same knitting cycle. The course may comprise one or more stitch types, such as a knit stitch, a held stitch, a float stitch, a tuck stitch, a transfer stitch, a rib stitch, and the like, as these terms are known in the art of knitting. The term “knit stitch, ” as used herein, refers to the basic stitch type where the yarn is cleared from the needle after pulling a loop of the yarn from the back to the front of the textile through a previous stitch and may be referred to herein as “knit loop. ” The term “wale, ” as used herein, is a predominantly vertical column of intermeshed or interlooped knit loops, generally produced by the same needle at successive (but not necessarily all) courses or knitting cycles. Knitted components described herein may include weft-knitted or warp-knitted components.
[0022] Courses of knitted components described herein may extend laterally, in a direction extending from a lateral side to a medial side of the upper, may extend longitudinally or in a direction from the toe region to the heel region, or may extend radially. The term “radially extending, ” as used herein, refers to an orientation of a knit course that radiates out from a common portion of the knitted component. Specifically, the knit course may be radially extending if it extends between an outer perimeter (referred to herein as an outer boundary) of the knitted component and the common portion. In this manner, the courses may radiate inwards from the outer perimeter towards the common portion and do not, for example, extend continuously across the body of the knitted component from a lateral side edge to a medial side edge of the outer perimeter. The structures of the knitted component may be radially extending from the common portion when the knitted component is laid out in a flat configuration after knitting, but it is also contemplated that determining whether structures are radially extending may be based on the orientation of the structures towards the common portion after the knitted component is folded into the shape of an upper or a portion of an upper.
[0023] The term “common portion, ” as used herein, refers to an area of the knitted component towards which multiple similar structures (e.g., multiple courses) extend. As such, courses may extend from an outer perimeter to a single common portion rather than extending generally parallel from the outer perimeter towards the other side. The common portion is spaced-apart from the outer perimeter and, in various aspects, may be relatively centrally located within the knitted component. In this way, the common portion may encompass and / or be directly adjacent to the longitudinal axis of the knitted component. In some examples disclosed herein, the common portion may include a throat region or a portion thereof.
[0024] The term “integrally knit, ” as used herein, may mean a knit textile having a yarn from one or more knitted courses in one area being interlooped with one or more knitted courses of another area. The interlooping may be through a simple knit stitch, a tuck stitch, a held stitch, a float or miss stitch, and the like. In this way, areas that are integrally knit together have a seamless transition.
[0025] The term “jig system” refers herein to a jig frame and one or more jig inserts that can be configured to secure a textile. As used herein, the term “jig frame” refers to a device that can be configured to temporarily but stably secure, mount, attach, or otherwise affix a textile to facilitate processing of that textile. As such, a “jig frame” may also be referred to as a “securing assembly” , “securing plate” , “mounting assembly” , “frame” , or the like. For example, the disclosed jig may be used to secure an upper of an article of footwear, allowing an operator to perform various operations on the secured upper before final assembly of the shoe.
[0026] The jig frame includes one or more pin attachment sites. The term “pin attachment site” as used herein refers to any structure capable of receiving and at least temporarily securing a pin. For example, pin attachment sites may include notches, recesses, apertures, magnetic attachments, slots, grooves, or any other suitable means for attaching a pin. In some embodiments, a pin attachment sites are configured to reversibly attach a pin. In this way, a jig system may be configured to secure a textile using various configurations of jig inserts as well as to secure various sizes and shapes of textiles.
[0027] As used herein, the term “pin” refers to any of various implements that can fasten a piece of cloth to another component. In various aspects, pins may be generally thin and may have a narrowed, tapered, or sharpened tip at one or both ends. In some cases, a pin may be cylindrical or peg-shaped, with or without a narrowed, tapered, or sharpened tip. Pins may be metal, plastic, or other rigid or semi-rigid material suitable for the purposes outlined herein. For example, injection-molded plastic may be a suitable material for pins in certain applications. Once attached at a pin attachment site, pins are expected to be relatively stable, to facilitate subsequent mounting and manipulation of a textile on the jig. However, in embodiments, pins are also configured to detach, as desired by an operator.
[0028] It is understood that a plurality of pins will generally be used to effectively secure a textile using the disclosed adjustable jig. As used herein, the term “pin pattern” may refer to a specific arrangement of pins corresponding to a given jig frame. For example, a pin pattern for some embodiments where the one or more jig inserts are not directly secured to the jig frame during processing may be different than a pin pattern for other embodiments where the one or more jig inserts are directly secured to the jig frame during process. Further, in some embodiments where there are at least two jig inserts, a pin pattern may be used in which at least one jig insert is not directly secured to the jig frame when the textile is secured to the jig frame and at least one jig insert is directly secured to the jig frame when the textile is secured to the jig frame.
[0029] The term “jig insert” refers herein to an elongate member that can be inserted into a textile (e.g., a tunnel formed by two at least partially separable layers of the textile) . A jig insert may be rigid or flexible, and a combination of rigid and flexible inserts may be inserted into the same textile.
[0030] Additionally, there are various measurements provided herein. Unless indicated otherwise, all measurements provided herein are taken when the knitted component, upper and / or article of footwear is at standard ambient temperature and pressure (298.15 K and 100 kPa) and is in a resting (non-tensioned) state. Unless indicated otherwise, the term “about” or “substantially” with respect to a measurement means within ± 10%of the indicated value. In some cases, a measurement of distance (e.g., a width of a knitted tunnel) may be provided as a number of knit stitches. In such cases, it should be understood that one knit stitch is the equivalent of about 1 millimeter ( “mm” ) .
[0031] FIG. 1A depicts an example jig system 100, in accordance with aspects hereof. Jig system 100 is depicted as being comprised of a jig frame 102, which may also be referred to as a jig plate, having a generally rigid or semi-rigid structure defining a space on which a textile can be secured. The jig frame may be formed using metal (e.g. aluminum or other alloys) , plastic or other polymeric materials, wood, composite materials, or any material or collection of materials suitable for the purposes disclosed herein. The jig frame may have any dimensions large enough to mount one or more textiles. In some embodiments, the jig frame is substantially rectangular. In some embodiments, the adjustable jig and / or frame is substantially square. The jig frame may have a depth or thickness.
[0032] The jig frame 102 includes a plurality of pin attachment sites 140 each configured to receive a pin for securing a textile on a surface of the jig frame 102. The pin attachment sites 140 may comprise openings on one surface of the jig frame 102 and extending at least partially through the thickness of the jig frame 102.
[0033] The pin attachment sites 140 define generally extend around a boundary of the textile when the textile is secured to the jig frame 102. As such, the pin attachment sites are arranged in a pin pattern that generally corresponds to the shape of the textile to which the jig frame 102 is configured to be secured. Example aspects herein are directed to securing a textile for forming an upper with the jig system 100. As such, the pin attachment sites 140 in FIG. 1A, as well as other example embodiments in FIGS. 4-7, generally form the shape of a textile upper component prior to the component being formed into a shape for receiving a foot. In this way, the pin attachment sites 140 define areas of the jig frame 102 that correspond to areas of a textile upper component. For example, the jig frame 102 includes a toe region 110, a midfoot region 111, a heel region 112, a lateral side 114, and a medial side 115.
[0034] The pin attachment sites 140 define an outer securing boundary 141 of the jig system 100, at which an outer boundary of a textile (e.g., outer boundary 161 of the textile 150 in FIG. 2) is secured to the jig frame 102. The outer securing boundary 141 include pin attachment sites 140 in the toe region 110, midfoot region 111, and heel region 112 along both lateral and medial sides 114 and 115.
[0035] Additionally, in some aspects, the pin attachment sites 140 also define an inner securing boundary 142 of the jig system 100, at which an inner boundary of the textile is secured to the jig frame 102. For example and as further illustrated in FIG. 2, a textile may include an inner boundary that forms a throat opening and / or ankle opening, and as such, inner securing boundary extends along a corresponding throat region 113 and collar region 117 of the jig frame 102. In other aspects, the textile to be secured to the jig frame 102 is an upper component but does not have an opening for the throat and corresponding embodiments of the jig frame 102 may have an inner securing boundary 142 along a collar region 117 only.
[0036] In addition to pin attachment sites 140, outer securing boundary 141, and in some aspects, inner securing boundary 141 are also defined by one or more jig inserts that are configured to extend between adjacent pin attachment sites 140. As previously described, the jig insert (s) provide structure to an edge of the textile as it is secured on the jig frame 102 so that the edge of the textile is more uniformly stretched and secured to the jig frame 102.
[0037] In the example embodiment of FIG. 1A, the jig system 100 includes a jig insert 120 extending between and along pin attachment sites 140 along the outer securing boundary 141. In this example, the jig insert 120 is a single jig insert extending continuously along the entire length of the outer securing boundary 141. In the illustrated embodiment, the jig insert 120 extends from the heel region 112 on the lateral side 114 of the jig frame 102 through the midfoot region 111 to the toe region 110, across to the medial side 115 of the toe region 110, and back through the midfoot region 111 to the heel region on the medial side 115 of the jig frame 102.
[0038] Using a single insert 120 for the entire length of the outer securing boundary 141 may simplify production processes by reducing the number of components to track and reduce time for inserting and removing inserts as described further herein. For example, inserting and removing only one insert reduces manufacturing time and also requires less pin attachment sites, which further reduces manufacturing time and reduces possible inconsistencies in the final textile product.
[0039] Further, in example aspects, the jig insert 120 is a flexible rod. As such, the jig insert 120 has a generally elongate and thin body formed of a flexible material in that it can bend and flex with minimal force, such as force caused by a human operator. The flexible nature of the jig insert 120 may enable the jig insert 120 to extend around the entire outer securing boundary 141 and be inserted and removed from the textile, as described further, with relative ease.
[0040] Additionally, the flexible nature of the jig insert 120 allows the jig insert 120 to take along different shapes of outer securing boundaries. As such, the same jig insert 120 may be used for textiles of different shapes and sizes, including for both right and left uppers of the same pair or for uppers with different configurations.
[0041] The jig insert 120 may be made of a fluoropolymer. In one example, the jig insert 120 is made of a polytetrafluoroethylene ( “PTFE” ) fluoropolymer and may also be referred to as a Bowden tube or cable. Other example, include a flexible rod may at least partially from polychlorotrifluoroethylene (PCTFE) or other such PTFE alternatives. As such, in addition to having a flexible structure, the jig insert 120 may also have non-stick properties. The use of a material with non-stick properties, such as PTFE or PCTFE, prevents the textile (i.e., yarn) from adhering to the insert 120 during processing (e.g., heating, steaming, etc. ) the textile on the jig frame 102. Particularly, the textile may be formed by fusible yarn (s) that at least partially melt or soften during processing steps, and such materials for the jig insert 120 prevents the fusible yarn (s) , as well as any other material, from adhering to the jig insert 120. This not only helps maintain the integrity of the textile, it reduces cycle time for operators who can easily remove the jig insert 102 when it is not adhering to the textile. In some aspects, the jig insert 120 is a monolithic structure formed by a material composition, such as PTFE. A monolithic structure would be less susceptible to non-stick properties being worn down or peeling off. In other aspects, the jig insert 120 comprises a non-stick coating (such applied as an adhesive layer or applied solution) .
[0042] Aspects of the jig insert 120 have a width (or diameter where the insert has a circular cross-section) within a range of about 2 millimeters and about 5 millimeters. In one example, the jig insert 120 has a width or diameter of about 3 millimeters. Further, in some embodiments, the jig insert 120 is not directly secured to the jig frame 102 but, instead, is located adjacent to one or more pin attachment sites 140. This configuration allows for the use of a relatively thin jig insert (e.g., a width or diameter of about 3mm) that does not need an aperture to receive a pin in order to help secure a textile to the jig frame 120. Additionally, not securing the jig insert 120 directly to the jig frame 102 through a pin decreases manufacturing time by removing steps when securing the textile with the jig insert 120 to the jig frame 102 and either when removing the textile with insert 120 from the jig frame 102 or removing the insert 120 from the textile that is still secured to the jig frame 102.
[0043] The elongate body of the jig insert 120 extends from a first end 122 to a second end 123. In example aspects, the first and second ends 122 and 123 of the jig insert 120 are thinner than the rest of the jig insert 120. FIG. 1B depicts a close-up view of the first end 122 relative to the rest of the jig insert 120. As depicted, the first end 122 has a height 125 extending from a first surface to an opposite second surface that is less than the height 127 of an adjacent portion of the jig insert 120. In some aspects, the first and second ends 122 and 123 may be substantially flattened. Having the first and second ends 122 and 123 thinner than the rest of the jig insert may facilitate insertion and removal of the jig insert 120 into the textile and reduce the risk of damaging the textile. Having a rounded shape to the first and second ends 122 and 123 may also increase the ease of insertion and removal of the jig insert 120 while reducing the risk of damage to the textile. One way to create a jig insert 120 with this configuration is to heat the first and second ends 122 and 123 of the jig insert 120 and apply pressure to taper the ends 122 and 123. The first and second ends 122 and 123 may then be trimmed to create a rounded shape.
[0044] While the jig insert 120 illustrated in FIGS. 1A-B comprise the flexible rod, it is contemplated that the jig insert 120 may have a more rigid structure, similar to the structure described for jig inserts 130 and 132 below.
[0045] Some aspects include one or more jig inserts along the inner securing boundary 142. As depicted in FIG. 1A, there are two jig inserts 130 and the jig insert 132 positioned in the throat region 113 of the jig frame 102. The jig insert 130 is positioned on the lateral side 114 of the throat region 113, and the jig insert 132 is positioned on the medial side 115 of the throat region 113. In some aspects, the jig inserts 130 and 132 are rigid inserts in that they generally have a predefined shape and do not flex around the pin attachment sites 140, compared to a flexible rod insert previously described that can be flexed and bent to form various shapes with minimal force. This rigid structure may be formed with a fiber board, fiber glass, stainless steel, ceramic, glass, aluminum, and the like. Further, the jig inserts 130 and 132 may have a curved shape corresponding to a portion of the inner securing boundary 142.
[0046] Similar to the jig insert 120, jig inserts 130 and 132 may have non-stick properties. For example, a non-stick solution (such as PTFE or PCTFE) may be applied to one or more sides of each jig insert, a non-stick adhesive may be applied to one or more sides of each jig insert, or non-stick material may be shrink wrapped around each insert 130 and 132. For example, in one aspect, the jig inserts 130 and 132 each include a piece of fiber board or stainless steel with a PTFE shrink-wrapped layer around the fiber board or stainless steel. Further, in other aspects, the jig inserts 130 and 132 may each be monolithic components made from a material with non-stick properties such as PTFE.
[0047] Additionally, in some aspects, the ends of the jig inserts 130 and 132 each include an aperture that aligns with a pin attachment site along the inner securing boundary 142. These apertures are configured to receive a pin similar. In this way, the jig inserts 130 and 132 directly secure to the jig frame 102 at inner securing boundary 142.
[0048] In other embodiments, there may only be one jig insert in the eye stay region 113. For example, a jig insert comprising a single flexible rod, similar to jig insert 120, may extend continuously along the lateral side 114 of the throat region 113 and along the medial side 115 of the throat region 113.
[0049] FIG. 2 depicts a top view of an example textile 150 attached to the jig system 100 of FIG. 1A, in accordance with aspects hereof. In example aspects, the textile 150 is a knitted component. In some examples, the textile 150 is a knitted component with radially-knit courses that extend from an outer perimeter (e.g., outer boundary 161) to a common portion, such as a throat region 113, which may be defined by an inner secure boundary 142 as described herein. Radially-extending courses within the knitted component 140 may divide the knitted component 140 into wedge-shaped portions including both full-length, radially-extending courses and partial-length, radially-extending courses.
[0050] As such, the textile 150 may be referred to herein as a knitted component and aspects of the textile 150 are described below with respect to knitted structures. However, it should be understood that, unless otherwise indicated, the textile 150 is capable of being formed from non-knitting techniques and have non-knitted structures such that, unless indicated otherwise, reference to the knitted component or knitted structures thereof may apply to non-knitted embodiments, such as woven and non-woven textiles.
[0051] Properties may be imparted to various areas of the textile in accordance with selected knit structures and types of yarn. Example yarns forming the textile 150 may include yarns of synthetic material, including polyethylene terephthalate (PET) yarns (commonly known as polyester) , including recycled PET, polyamide yarns (commonly known as nylon) , elastane, and combinations thereof. In some aspects, at least a portion of the textile 150 includes “high-melting yarn” , which generally means that the yarn melts at about 175 degrees Celsius or higher. Additionally, in some aspects, a high-melting yarn may be arranged (e.g., knit) with a low-melting yarn, which may be a low-melting thermoplastic yarn, in the textile 150. As used herein, the term “low-melting” generally means yarns that melt at about 170 degrees Celsius or less. The low-melting thermoplastic yarns may comprise a synthetic polymeric material formed from a polymer that melts at relatively low temperatures. In example aspects, the low-melting yarns may include yarns that are entirely formed from a low-melting thermoplastic material such as low-melting PET or low-melting polyamide. In other aspects, a low-melting yarn may include a yarn with sheath made of a low-melting thermoplastic polymer, including but not limited to a thermoplastic polyurethane (TPU) or thermoplastic polyethylene (TPE) , around a high-melting core yarn.
[0052] Further, a yarn forming the textile 150 may be a mono-filament yarn or a multi-filament yarn. As such, unless otherwise specified, the term “yarn" ” as used herein, does not require multiple filaments or fibers. The yarn may also include separate filaments that are each formed of different materials. In addition, the yarn may include filaments that are each formed of two or more different materials, such as a bi-component yarn with filaments having a sheath-core configuration or two halves formed of different materials. Other configuration of the yarn structure may be used in accordance with aspects of this disclosure.
[0053] At least part of textile 150 is defined by an outer boundary 161. A shape of outer boundary 161 may generally correspond to a shape of the outer securing boundary securing 141 of the jig frame 121. The textile 150 includes a tunnel 160 (which may be referred to herein as a knitted tunnel or outer knitted tunnel 160) along the outer securing boundary 161. FIG. 3 depicts a magnified view of the textile 150 to show details of the knitted tunnel 160. The knitted tunnel 160 includes a first layer 163 and a second layer 165 coextensive with the first layer 163. The first and second layers 163 and 165 are separable at least at the knitted tunnel 160 such that a pocket 169 is formed between the first and second layers 163 and 165, where the pocket 169 is configured to receive the jig insert 120. The first layer 163 and the second layer 165 are joined at a first edge 166 (which may be referred to herein as an inner edge 166) and a second edge 167 (which may be referred to herein as an outer edge 167) . The pocket 169 of the knitted tunnel 160 extends between the first and second layers 163 and 165, and between the inner edge 166 and the outer edge 167.
[0054] The second layers 163 and 165 are secured together at the inner edge 166 and the outer edge 167. For example, in aspects in which the textile 150 is a knitted component, the yarn from the first and second layers 163 and 165 may be interloped together such that the first and second layers 163 and 165 are not separable at those edges. In various aspects, the outer edge 167 of the knitted tunnel 160 at least partially defines the outer boundary 161 of the textile 150 such that the textile 150 terminates at the outer edge 167 (e.g., does not extend past outer edge 167) . In other aspects, the textile 150 may include a portion between the outer edge 167 of the knitted tunnel 160 and the outer boundary 161 where the first and second layers 163 and 165 extend, either interloped together or separable. The textile 150 similarly extends beyond the inner edge 166, either with the first and second layers 163 and 165 interloped together or separable.
[0055] A width 175 of the knitted tunnel 160 is measured by the distance between the inner edge 166 and the outer edge 167. The width 175 of the knitted tunnel 160 may be measured in a number of knit stitches that is within a range from about 3 knit stitches to about 15 knit stitches. In some aspects, particularly ones in which the jig insert 120 is a flexible rod, the width 175 of the knitted tunnel 160 is no greater than 10 knit stitches and may be about 7 knit stitches in some aspects or about 3 knit stitches in other aspects. In other aspects, the width 175 of the knitted tunnel 160 is within a range from about 12 knit stitches to about 10 knit stitches.
[0056] The width 175 of knitted tunnel 160 is generally sized to accommodate the jig insert 120 but still small enough that knitted tunnel can be maintained below a biteline when it the textile is incorporated as an upper and joined with a sole structure. To accomplish this, a relationship between a width of a jig insert 120 and width 175 of the knitted tunnel a knitted tunnel 160 preferably results in the knitted tunnel 160 being about 1 to 4 knit stitches (e.g., about 1mm to 4mm) wider than the jig insert. For example, in an embodiment where the jig insert 120 is a flexible rod with a diameter of about 3mm, the width 175 of the knitted tunnel 160 may be about within a range from about 4 mm (e.g., knit stitches) to about 8 mm (e.g., knit stitches) and in some examples, is about 7mm (e.g., 7 knit stitches) . The same application may apply to jig inserts and knitted tunnels configured for the insertion of jig inserts in embodiments discussed in FIGS. 4-8. One of the benefits of such a configuration is that it allows the jig inserts to not only be easily inserted and navigated through any turns or bends present in the knitted tunnels without snagging, but also to be easily removed from the knitted tunnels following post-processing steps, which may include heating, steaming, pressing, printing, embroidering, and / or chemical applications. This is due to potential shrinkage of the knit structure forming knitted tunnels after being exposed to such post-processing steps.
[0057] Additionally, a width of the knitted tunnels (e.g., knitted tunnel 160 or any of the knitted tunnels described in the discussion of FIGS. 4-8 below) may not remain constant but, instead, may vary along a length of the knitted tunnels. In some embodiments, the width 175 (e.g., first width) of knitted tunnel 160 in a first location may be different than a width 176 (e.g., a second width) of knitted tunnel 160 in a second location. For example, the width 175 of the knitted tunnel 160 may be about 6 knit stitches whereas the width 176 may be about 7-8 knit stitches (e.g., the first width 175 in a first location is less than the second width 176 in the second location) . Generally, areas where the knitted tunnel 160 curves may have greater width (s) compared to areas in which the knitted tunnel 160 is more linear. Such areas with greater widths may be present where the textile 150 narrows on lateral and / or medial sides 114 and 115 of the toe region 110, as indicated by width 176 in FIG. 3, or in other locations, such as curves in the shape of the textile 150 around the heel region 112 depicted in FIG. 2. Areas of the first width where the knitted tunnel 160 is more linear includes the midfoot region 111 on lateral and / or medial sides 114 and 115, as well as other positons shown in the figures. Such a configuration may be advantageous to allow for jig insert 120 to be inserted through any bends or turns without getting caught up in the knitted tunnel 160. A varying width of a knitted may be similarly applied to the embodiments described in the discussion of FIGS. 4-8 below, where a difference in widths of the knitted tunnel within different locations may be about 1 to 5 knit stitches.
[0058] The first and second layers 163 and 165 of the knitted tunnel 160 may be knitted on different needle beds (e.g., a first needle bed knitting the first layer 163 and a second needle bed knitting the second layer 165) . At least a portion of the first and second layers 163 and 165 may be secured together at to form the inner and outer edges 166 and 167 of the knitted tunnel 160. The width 175 of the knitted tunnel 160 may be controlled by knitting the separate layers for a predetermined number of needles beyond the body of the textile. For example, the first and second layers 163 and 165 may be knit separately along a number of needles between 15 needles to about 5 needles. In some aspects, particularly ones in which the jig insert 120 is a flexible rod, the first and second layers 163 and 165 are knit separately along no more than 10 needles and, in some aspects, are knit separately along 7 needles or along 3 needles. In other aspects, the first and second layers 163 and 165 are knit separately along a number of needles between about 12 knit and about 10.
[0059] In the embodiment of FIG. 2, the knitted tunnel 160 extends from the heel region 112 on the lateral side 114 of the jig frame 102 through the midfoot region 111 to the toe region 110, across to the medial side 115 of the toe region 110, and back through the midfoot region 111 to the heel region on the medial side 115 of textile 150. In some embodiments, the knitted tunnel 160 is formed as one continuous tunnel without breaks, which helps reduce scalloping and creates a clean outer edge of the textile 160. The knitted tunnel may have two pocket openings 162 and 164, where the jig insert 120 may be inserted and routed through to exit through the other of the two openings. In this example, the pocket opening 162 may be located in the midfoot region 111 on the medial side 115 of textile 150, and the pocket opening 164 may be located in the heel region 112 on the lateral side 114 of textile 150. In other aspects, the textile 150 has a more symmetrical configuration between the lateral and medial sides such that the locations of the pocket openings 162 and 164 may be mirrored.
[0060] As previously described and as shown in FIG. 2, the textile 150 is secured to the pin attachment sites 140 of the jig frame 102 through pins, which extend through the textile 150. As such, the location of the pin holes corresponds with pin attachment sites 140 on the jig frame 102. In some embodiments, one or more pin holes are integrally formed into the textile 150. For example, pin holes may be integrally knit through transfer stitches to create an opening during the knitting processing, where the opening (or pin hole) helps to facilitate securing textile 150 to the jig frame 102. In other embodiments, pin holes may be created after knitting, through punching or cutting by example. In some aspects, the textile 150 includes a piece of waste yarn, which may be a short piece of yarn inserted during knitting without being interloped with another strand so that the waste yarn can be pulled out with of the textile 150 with ease) . The waste yarn may help an operator quickly locate a pin hole so that the operator knows where to load the textile 150 on the jig frame 10 to make the process more efficient. Such waste yarn may also act to help serve as measurement points to ensure accuracy of the patterning and production process.
[0061] In some aspects, pin holes are formed interior to the inner edge 166 of the knitted tunnel 160. Positioning pin holes (and therefore pins) interior to the inner edge 166 may better support the textile compared to when the pin holes extend through the knitted tunnel 160 where two separate layers are present. Additionally, it is easier to integrally form pin holes in a knitted textile when such holes extend through a single layer than having to knit and align pin holes in two separate layers.
[0062] As depicted in FIG. 2 (as well as in FIG. 1A) , the pin attachment sites 140 include some pin attachment sites that are positioned farther from the outer boundary 161 or edge of the textile 150 than other pin attachment sites when the textile 150 is secured to the jig frame 102. As such, the pin attachment sites may include interior pin attachment sites (positioned farther from the outer boundary 161) and exterior pin attachment sites (positioned closer to the outer boundary 161) . The outer boundary 161 here may also be the outer edge 167 of the knitted tunnel 160. When the jig insert 120 is inserted into the knitted tunnel 160 and the textile 150 is secured to the jig frame 102, the jig insert 120 may extend interior to the exterior pin attachment sites and exterior to the interior pin attachment sites. As such, interior pin attachment sites may help the jig insert 120 and prevent it from flexing inward when tension is applied, while exterior pin attachment sites help guide the jig insert. Both interior and exterior pin attachment sites help to keep the jig insert in place in order to maintain a smooth and clean outer boundary 161 of the textile 150. Generally, the jig frame 102 includes more interior pin attachment sites than exterior pin attachment sites to ensure a sufficient tension is applies to the outer boundary 161 of the textile 150 to reduce or eliminate scalloping. However, in some locations such as heel region 112, there may be more interior pin attachment sites than exterior attachment sites. Additionally, at some locations include a configuration of at least one exterior pin attachment site positioned between two interior pin attachment sites. For example, interior pin attachment sites 143 and 145 and exterior pin attachment site 144 depict such a configuration in the heel region 112, which helps to guide the jig insert 120 through an angled portion of the outer boundary 161 of the textile 150.
[0063] As described with respect to FIG. 1A, the jig insert 102 may be positioned along an inner securing boundary 142. As such, the textile 150 may further include tunnels 170 and 174 (which may be referred to herein at knitted tunnels 170 and 174 or inner knitted tunnels 170 and 174) . Inner knitted tunnels 170 and 174 are positioned on the medial side 115 and the lateral side 115 of the throat region 113, respectively. The inner knitted tunnels 170 and 174 may form eyestay regions of an upper. An eyestay region may include apertures through which laces pass. In some embodiments, the inner knitted tunnels 170 and 174 may each form a plurality of integrally knit tunnels between first and second knit layers along the eyestay region, where each integrally knit tunnel serves as a lace aperture. In such an embodiment, the lacing system may be incorporated into this eyestay region in the later stages of the process depending on the desires of the operator. In other embodiments, lace apertures in the eystay region may be integrally knitted openings extending through both the first and second layers of the knitted tunnels 170 and 174, either through transferring stitches during knitting or through a post-knitting step, such as cutting or punching. Inner knitted tunnels 170 and 174 are configured to receive jig inserts 132 and 130, respectively. Similar to knitted tunnel 160, inner knitted tunnels 170 and 174 are formed from first and second layers with a pocket space there between.
[0064] The inner knitted tunnels 170 and 174 may generally have mirrored configurations. For ease, reference is made to inner knitted tunnel 170, which is shown in the magnified view of FIG. 3, but it should be understood that such details also apply to the inner knitted tunnel 174. The width 185 of the inner knitted tunnel 170 extends from an inner edge 178 and an outer edge 179 where the two layers forming the tunnel are joined. The width 175 of inner knitted tunnel 170 (and similarly of inner knitted tunnel 174) may have any of the widths described with respect to the knitted tunnel 160. In some aspects, however, different types of inserts are used for the knitted tunnel 160 along the outer securing boundary 141 and the knitted tunnels 170 and 174 along the inner securing boundary 142. For example, the knitted tunnel 160 may be configured to receive a flexible rod insert, while the knitted tunnels 170 and 174 may be configured to receive a rigid, wider insert. As such, in some aspects, the width 185 of each of the knitted tunnels 170 and 174 may be greater than the width 175 of the knitted tunnel 160. For instance, the width 185 of the knitted tunnel 170 and 174 may be between about 10 knit stitches and about 15 knit stitches, whereas the width 175 of the knitted tunnel 160 may be no greater than 10 knit stitches, such as 7 knit stitches or 3 knit stitches.
[0065] Unless otherwise indicated, the inner knitted tunnels 170 and 174 may have a similar construction as the knitted tunnel 160 and further details of the knitted tunnel 160 will be understood to apply to the inner knitted tunnels 170 and 174 without repeating such here.
[0066] While inner knitted tunnels 170 and 174 may be formed as one continuous tunnel without breaks, breaks in the tunnels may also be formed to facilitate insertion and removal of the inserts jig inserts 130 and 132. For example, the knitted tunnels 170 and 174 could each have two pocket openings –one more anterior and one more exterior –within the throat region 113. Additionally, while FIG. 2 depicts two knitted tunnels 170 and 174 configured to receive two jig inserts 130 and 132, it is also conceivable that one knitted tunnel could be formed to receive two jig inserts or one extended jig insert spanning the distance of both jig inserts 130 and 132 or that two knitted tunnels 170 and 174 may be configured to receive a single extended jig insert, as discussed further in regards to FIGS. 4-7.
[0067] FIG. 4 depicts another example jig system 400, in accordance with aspects hereof. Jig system 400 includes a jig frame 402 and multiple inserts (e.g., jig inserts 420 and 422) configured to extend along an outer securing boundary 441 of the jig system 400. The jig frame 402 includes a plurality of pin attachment sites 440. Aside from the number of and arrangement of pin attachment sites 440, the jig frame 402 has generally the same or similar configuration as jig frame 102 discussed with respect to FIGS. 1A-3. As such, various details and examples of jig frame 102 equally apply to jig frame 402 and components thereof without being repeated, unless otherwise indicated.
[0068] In addition to pin attachment sites 440, the outer securing boundary 441, which may have similar characteristics of the outer securing boundary 141, is also defined by jig inserts 420 and 422. Similar to the jig insert 120, the jig inserts 420 and 422 are configured to extend between adjacent pin attachment sites 440 and provide structure to an edge of the textile as it is secured on the jig frame 402 so that the edge of the textile is more uniformly stretched and secured to the jig frame 402. However, multiple jig inserts 420 and 422 are configured to define the outer securing boundary 441 of the jig system 400 instead of a single jig insert.
[0069] In example aspects, the jig inserts 420 and 422 are rigid inserts in that they generally have a predefined shape and do not easily flex around the pin attachment sites 440. The jig inserts 420 and 442 may be formed of the same material (s) and have the same or similar characteristics as jig inserts 130 and 132 previously discussed. As such, the characteristics and properties described with respect to examples of the jig inserts 130 and 132 apply to jig inserts 420 and 442 except as otherwise indicated. Other examples of jig inserts 420 and 442 may have a more flexible structure, such as a flexible rod, as previously described with respect to the jig insert 120.
[0070] In the example depicted in FIG. 4, the jig insert 420 extends from an end of the jig insert 420 located in the midfoot region 411 on the medial side 415 of the jig frame 402 to the toe region 410, and across to the lateral side 414 of the toe region 410 where the other end of the jig insert 420 is located. The jig insert 422 extends from an end of the jig insert 422 located in the heel region 412 on the lateral side 414 to the toe region 410 on the lateral side 414 where the other end of the jig insert 422 is located.
[0071] Each of the jig inserts 420 and 422 may generally have a shape corresponding to a portion of the outer securing boundary 441 of the jig system 400. In this way, each of the jig inserts 420 and 422 may have one or more curvatures, such as a curvature around an anterior part of the toe region 410 (see jig insert 420) or a curve in the heel region 412 (see jig insert 422) . In the configuration shown in FIG. 4, the jig inserts 420 and 422 have different shapes and are not mirrors of each other. It is contemplated that jig inserts 420 and 422 may have different shapes based on the configuration of the textile to be secured to the jig frame 402. For example, jig inserts may have a more symmetric or mirrored shape if they were to secure a textile with more symmetry between lateral and medial sides
[0072] As described with respect to jig inserts 130 and 132, jig inserts 420 and 422 may be directly secured to the jig frame 402. This configuration includes one or more apertures in each of the jig inserts 420 and 422 so that they can receive a pin in order to help secure a textile to the jig frame 402. As depicted in FIG. 4, each end of each of the jig inserts 420 and 422 includes an aperture for receiving a pin. Pin attachment sites 440 corresponding to ends of the jig inserts 420 and 422 help to maintain a positioning of the jig inserts 420 and 422 so that they do not slide out of a textile. Some examples further include one or more additional apertures between the two ends of the respective jig inserts. For example, FIG. 4 depicts each of the jig inserts 420 and 422 having one additional aperture between the end apertures, for a total of three apertures for receiving pins. These additional apertures and corresponding pin attachment sites on the jig frame 402 helps prevent the jig inserts 420 and 422 from flexing inward when pressure is applied. Both pin attachment sites corresponding to the ends of the jig inserts 420 and 422 and those in between help to keep the jig insert in place in order to maintain a smooth and clean edge of a textile being secured.
[0073] In some examples, each end of the jig inserts 420 and 422 are narrower than intermediate portions of the jig inserts 420 and 422. For example, in some embodiments, the width of each jig insert 420 and 422 is about 8 millimeters, whereas each end of the jig inserts 420 and 422 have a width of about 6 millimeters. A relatively narrower end of the jig inserts 420 and 422 allows for easier insertion and removal, whereas a relatively wider intermediate provides more structure and support.
[0074] The jig system 400 also includes an inner securing boundary 442 at which an inner boundary of the textile is secured to the jig frame 402. The inner securing boundary 442 may have similar or the shape properties as the inner securing boundary 142 of FIGS. 1A-3 unless otherwise indicated. For example, like the inner securing boundary 142, the inner securing boundary 442 is defined at least by some pin attachment sites 440. Further, in some aspects, the inner securing boundary 442 is defined by one or more jig inserts. As depicted in FIG. 4, a jig insert 430 is located in a throat region 413 of the jig frame 402. In this example, jig insert 430 is the only insert forming the inner securing boundary 442 and extends from the throat region 413 on the lateral side 414 to the throat region on the medial side 415. But it is contemplated that in other embodiments, there may be two or more jig inserts in the inner securing boundary 442, and more specifically in the throat region 413. For example, the inner securing boundary 442 may include two inserts having the same shape and placement as jig inserts 130 and 132.
[0075] The jig insert 430 is depicted as rigid insert and may be made from the same material (s) and have a similar construction as described with respect to the jig inserts 130 and 132. Further, as described with respect to jig inserts 130 and 132, the jig insert 430 may include apertures aligning with pin attachment sites 440 on the jig frame 402 so that the jig insert 430 may be directly secured to the jig frame 402. For example, the jig insert 430 includes an aperture near each end that aligns with the pin attachment sites 440 within the inner securing boundary 442. The jig insert 430 is also depicted as having two pin attachment sites that correspond with two apertures on the jig insert 430 located between the ends of the jig insert 430, such as in the area where the jig insert 430 extends between lateral and medial sides of the throat region 413; however, it is contemplated that there could be one or no pin attachment sites and one or no corresponding apertures at such a location.
[0076] FIG. 5 depicts a top-down view of a textile 450 attached to the jig system 400 of FIG. 4, in accordance with aspects hereof. Textile 450 may have the same or similar characteristics and properties as described with respect to examples of the textile 150 except where otherwise indicated. For example, the textile 450 may be a knitted component. Additionally, the textile 450 may have one or more outer tunnels (e.g., outer knitted tunnels 460 and 464) extending along an outer boundary 461 of the textile 450 that generally corresponds with the shape of the outer securing boundary of the jig system 400.
[0077] Example aspects of the outer knitted tunnels 460 and 464 generally have similar configurations as the knitted tunnel 160 of FIG. 2. Whereas the textile 150 has one knitted tunnel 160 along the outer boundary 161 for receiving one insert jig 120, the textile 450 has two knitted tunnels 460 and 464 along the outer boundary 461 for receiving two jig inserts 420 and 422. However, similar to the outer knitted tunnel 160, the outer knitted tunnels 460 and 464 may each be formed of two coextensive layers that are separable at least at the knitted tunnels 460 and 464 such that a pocket for receiving jig inserts 420 and 422 is formed between the two layers. As such, details of the construction and properties of the outer knitted tunnel 160 apply to knitted tunnels 460 and 464 unless otherwise indicated.
[0078] The outer knitted tunnel 460 is configured to receive the jig insert 420 and, as such, extends from the midfoot region 511 on the medial side 415 of the textile 450 to the toe region 510 on the medial side 415, across to the toe region 510 on the lateral side 414 of textile 450. The outer knitted tunnel 464 is configured to receive the jig insert 422 and, as such, extends from the heel region 512 on the lateral side 414 through the midfoot region 511 to the toe region 510 on the lateral side 415 of textile 450.
[0079] Similar to the outer knitted tunnel 160, each of the outer knitted tunnels 460 and 464 have a width 486 defined by a first edge 482 (which may be referred to as an inner edge 482) and an a second edge 484 (which may be referred to as an outer edge 484) where the two layers forming the tunnel are joined. In various aspects, the width 486 of each outer knitted tunnel 460 and 464 may be measured in a number of knit stitches that is within a range from about 5 knit stitches to about 15 knit stitches. In some aspects, the width 486 is about no greater than 15 knit stitches and may be about 10 knit stitches. In other aspects, the width 486 is within a range from about 12 knit stitches to about 10 knit stitches. The width 486 of outer knitted tunnels 460 and 464 are generally sized to accommodate the jig inserts 420 and 422 but still small enough that knitted tunnel 160 can be maintained below a biteline when the textile 450 is incorporated as an upper and joined with a sole structure (e.g., if the jig inserts 420 and 422 have a width of 8 knit stitches. In other aspects, the outer knitted tunnels 460 and 464 may be narrower, particularly where jig inserts 420 and 422 have a flexible rod as discussed previously with regards to FIGS. 1-3. As such some aspects of the width 486 is no more than 10 knit stitches and, in some aspects, being 7 knit stitches or 3 knit stitches.
[0080] In some embodiments, the outer knitted tunnels 460 and 464 are each formed as one continuous tunnel without breaks, which helps reduce scalloping and creates a clean edge of the textile 450. In other embodiments, the outer knitted tunnels 460 and / or 464 include breaks in one of the layers to create multiple pocket spaces and openings, where the jig inserts 420 and 422 extend across the breaks when they are inserted into the textile 450. Such breaks may help facilitate insertion and removal of the jig inserts 420 and 422, particularly where the jig inserts 420 and 422 have a rigid construction.
[0081] The outer knitted tunnel 460 includes two pocket openings 462 and 463 (one at each end of the outer knitted tunnel 460) , where the jig insert 420 may be inserted through one opening and routed through to the other of the two openings. The pocket opening 462 may be located in the midfoot region 511 on the medial side 415 of textile 450 and the pocket opening 463 may be located in the toe region 510 on the lateral side 414 of textile 450. The outer knitted tunnel 464 similarly includes two pocket openings 465 and 466, (one at each end of the outer knitted tunnel 464) , where the jig insert 422 may be inserted through one opening and routed through to the other. The pocket opening 465 may be located in the toe region 510 on the lateral side 414 and pocket opening 464 may be located in the heel region 512 on the lateral side 414. Although each of outer knitted tunnels 460 and 464 are depicted as having two openings, it is contemplated that each of outer knitted tunnels 460 and 464 may comprise a pocket opening at only one end, where the other ends of the outer knitted tunnel 460 and 464 are either each closed off or are joined so that the outer knitted tunnels 460 and 464 form a single continuous tunnel housing two jig inserts 420 and 422.
[0082] Also depicted in FIG. 5 is an inner knitted tunnel 470 in the throat region 413 of textile 450 along an inner boundary of the textile 450. Inner knitted tunnel 470 have generally have the same two-layered configuration as described with respect to the outer knitted tunnels 460 and 464. The inner knitted tunnel 470 is depicted as extending within the midfoot region 511 and the toe region 510 on the medial side 415 and the lateral side 414 of textile 450. The inner knitted tunnel 470 is configured to receive the jig insert 430. While FIG. 5 depicts one knitted tunnel in the throat region 413 (e.g., the inner knitted tunnel 470) that receives one jig insert (e.g., the jig insert 430) , it is also contemplated that one knitted tunnel with breaks or two separate knitted tunnels could be formed along the inner boundary of the textile 450 to receive one jig insert (e.g., the jig insert 430) . Alternatively, the inner boundary of the textile 450 may include two knitted tunnels for receiving two jig inserts in the same manner as shown and described with respect to FIG. 2.
[0083] In the example of FIG. 5, the inner knitted tunnel 470 may comprise a pocket opening 472 located on the medial side 415 of the throat region 413 that provides access for the jig insert 430 to be inserted into the pocket space of the inner knitted tunnel 470. The inner knitted tunnel 470 may also comprise a pocket opening 474 located on the lateral side 414 of the throat region 413 to provide access for the jig insert 430 inserted into the pocket space of the inner knitted tunnel 470. Although inner knitted tunnel 470 is depicted as having two pocket openings, it is contemplated that inner knitted tunnel 470 may comprise a pocket opening at only one end.
[0084] FIG. 6 depicts another example jig system 600, in accordance with aspects hereof. Jig system 600 includes a jig frame 602 and multiple inserts (e.g., jig inserts 620, 622, 624, and 626) configured to extend along an outer securing boundary 641 of the jig system 600. The jig frame 602 includes a plurality of pin attachment sites 640. Aside from the number of and arrangement of pin attachment sites 640, the jig frame 602 has generally the same or similar configuration as jig frame 102 discussed with respect to FIGS. 1A-3. As such, various details and examples of jig frame 102 equally apply to jig frame 602 and components thereof without being repeated, unless otherwise indicated.
[0085] In addition to pin attachment sites 640, the outer securing boundary 641, which may have similar characteristics of the outer securing boundary 141, is also defined by jig inserts 620-626. Similar to the jig insert 120, the jig inserts 620-626 are configured to extend between adjacent pin attachment sites 640 and provide structure to an edge of the textile as it is secured on the jig frame 602 so that the edge of the textile is more uniformly stretched and secured to the jig frame 602. However, multiple jig inserts 620-626 are configured to define the outer securing boundary 641 of the jig system 600 instead of a single jig insert.
[0086] In example aspects, the jig inserts 620-626 are rigid inserts in that they generally have a predefined shape and do not easily flex around the pin attachment sites 640. The jig inserts 620-626 may be formed of the same material (s) and have the same or similar characteristics as jig inserts 130 and 132 previously discussed. As such, the characteristics and properties described with respect to examples of the jig inserts 130 and 132 apply to jig inserts 620-626 except as otherwise indicated. Other examples of jig inserts 620-626 may have a more flexible structure, such as a flexible rod, as previously described with respect to the jig insert 120.
[0087] In the example depicted in FIG. 6, the jig insert 620 extends from an end of the jig insert 620 located in the midfoot region 611 on the medial side 615 of the jig frame 602 to the medial side 615 of the toe region 610 where the other end of the jig insert 620 is located. The jig insert 622 extends from an end located in the toe region 610 on the medial side 615 across to the lateral side 614 of the toe region 610 where the other end of the jig insert 622 is located. The jig insert 624 extends from an end in the lateral side 614 of the toe region 610 through the midfoot region 611 on the lateral side 14 to the heel region 612 on the lateral side 614 where the other end of the jig insert 624 is located. The jig insert 624 extends entirely within the heel region 612 on the lateral side 614. It should be understood that other arrangements of the four inserts 620-626 around the outer securing boundary 641 is contemplated.
[0088] Each of the jig inserts 620-626 may generally have a shape corresponding to a portion of the outer securing boundary 641 of the jig system 600. In this way, one or more of the jig inserts 620-626 may have one or more curvatures, such as a curvature around an anterior part of the toe region 610 (see jig insert 622) , while other jig inserts may have a generally straight configuration (such as jig inserts 620, 624, and 626) . In the configuration shown in FIG. 6, the jig inserts 620-626 have different shapes and sizes. It is contemplated that jig inserts 620-626 may have different shapes based on the configuration of the textile to be secured to the jig frame 620. For example, jig inserts may have a more symmetric or mirrored shape if they were to secure a textile with more symmetry between lateral and medial sides
[0089] As described with respect to jig inserts 130 and 132, jig inserts 620-626 may be directly secured to the jig frame 602. This configuration includes one or more apertures in each of the jig inserts 620-626 so that they can receive a pin in order to help secure a textile to the jig frame 602. As depicted in FIG. 6, each end of each of the jig inserts 620-626 includes apertures for receiving pins. Pin attachment sites 640 corresponding to ends of the jig inserts 620-626 help to maintain a positioning of the jig inserts 620-626 so that they do not slide out of a textile. In some aspects, each jig insert 620-626 include only two apertures for pins, but in other aspects, additional apertures corresponding to additional pin receiving sites may be included in one or more of the inserts 620-626 as described with respect to the jig inserts 420 and 422.
[0090] In some examples, each end of the jig inserts 620-626 are narrower than intermediate portions of the jig inserts 620-626. For example, in some embodiments, the width of each jig insert 620-626 is about 8 millimeters, whereas each end of the jig inserts 620-626 have a width of about 6 millimeters. A relatively narrower end of the jig inserts 620-626 allows for easier insertion and removal, whereas a relatively wider intermediate provides more structure and support.
[0091] The jig system 600 also includes an inner securing boundary 642 at which an inner boundary of the textile is secured to the jig frame 602. The inner securing boundary 642 may have similar or the shape properties as the inner securing boundary 142 of FIGS. 1A-3 unless otherwise indicated. For example, like the inner securing boundary 142, the inner securing boundary 642 is defined at least by some pin attachment sites 640. Further, in some aspects, the inner securing boundary 642 is defined by one or more jig inserts. FIG. 6 depicts an example with two jig inserts 630 and 632 in the throat region 613 of the jig frame 602. This configuration is has similar properties as described with respect to jig inserts 130 and 132 in jig system 100. In alternative aspects, the jig system 600 may include a single jig insert to form the inner securing boundary 646 as described with respect to the jig insert 430 in jig system 400.
[0092] FIG. 7 depicts a top-down view of a textile 650 attached to the jig system 600 of FIG. 6, in accordance with aspects hereof. The textile 650 may have the same or similar characteristics and properties as described with respect to examples of the textiles 150 and 450 except where otherwise indicated. For example, the textile 650 may be a knitted component. Additionally, the textile 650 may have one or more outer tunnels (e.g., outer knitted tunnels 660, 662, 664, and 666) extending along an outer boundary 661 of the textile 650 that generally corresponds with the shape of the outer securing boundary of the jig system 600.
[0093] Example aspects of the outer knitted tunnels 660-666 generally have similar configurations as the outer knitted tunnels 460 and 464 of FIG. 5. Whereas the textile 550 has two outer knitted tunnels 460 and 464 along the outer boundary 561 for receiving two jig inserts 420 and 422, the textile 650 has for knitted tunnels 660-66 along the outer boundary 661 for receiving four jig inserts 620-626. However, similar to the outer knitted tunnels 420 and 422, the outer knitted tunnels 660-666 may each be formed of two coextensive layers that are separable at least at the knitted tunnels 660-666 such that a pocket for receiving jig inserts 620-626 is formed between the two layers. As such, details of the construction and properties, including the width of the outer knitted tunnels 460 and 464 apply to knitted tunnels 660-666 unless otherwise indicated.
[0094] The outer knitted tunnel 660 is configured to receive the jig insert 620 is positioned on the textile 650 in a location similar to the previously described location of the jig insert 620. The outer knitted tunnel 662 is configured to receive the jig insert 622 is positioned on the textile 650 in a location similar to the previously described location of the jig insert 622. The outer knitted tunnel 664 is configured to receive the jig insert 624 is positioned on the textile 650 in a location similar to the previously described location of the jig insert 624. The outer knitted tunnel 666 is configured to receive the jig insert 626 is positioned on the textile 650 in a location similar to the previously described location of the jig insert 626. Additionally, each of the outer knitted tunnels 660-666 may include two pocket openings, one at each end of the respective outer knitted tunnel. Locations of the pocket openings may align with locations of the ends of the corresponding jig insert as described above.
[0095] Also depicted in FIG. 7 are two inner knitted tunnels 670 and 674 in the throat region 613 of textile 650 along an inner boundary of the textile 650. The inner knitted tunnels 670 and 674 may generally have the same configuration as the inner knitted tunnels 170 and 174 of the textile 150. In alternative aspects, the textile 650 may include a single inner knitted tunnel in the throat region 613 having the same configuration as described with respect to the inner knitted tunnel 470 of the textile 450.
[0096] With reference to FIG. 8, a method 800, described herein, can be implemented using any or all of the components and component interactions previously described in FIGS. 1-7. As such, the method is discussed briefly for brevity, though it will be understood that the previous discussion and details described therein can be applicable to aspects of the methods of FIG. 8.
[0097] A flow diagram showing the method 800 for manufacturing a textile with a jig system is provided in accordance with any one or more aspects of the present disclosure. For example, the textile referenced with respect to method 800 may be any aspects of textiles 150, 450, or 650, and the jig system referenced with respect to method 800 may be any aspects of the jig systems 100, 400, or 600.
[0098] At block 810, a first jig insert is inserted into a first tunnel of the textile. The first tunnel is located adjacent to an outer boundary of the textile. In some embodiments, the tunnel is as knitted tunnel formed by two knitted layers with a pocket in between. Some aspects of the method 800 further comprise the step of knitting the textile by integrally knitting a first layer and a second layer that are separable to form the first knitted tunnel. The textile may include one or more additional tunnels, such as a second tunnel, a third tunnel, or a fourth tunnel along the outer boundary of the textile. As such, in some embodiments, method 800 includes inserting a second jig insert into a second tunnel of the textile and, in further aspects, may include inserting third and fourth inserts into third and fourth tunnels.
[0099] At block 820, the textile containing at least the first jig insert is overlaid on a jig frame having one or more pin attachment sites for securing the textile to the frame. In some embodiments, overlaying the textile further comprises aligning a waste yarn incorporated into the first tunnel (e.g., a first knitted tunnel) with the one or more pin attachment sites.
[0100] At block 830, the textile is removably attached to the jig frame at the one or more boundary securing sites. In some embodiments, removably attaching the textile to the jig frame comprises securing the first jig insert within the first knitted tunnel to a pin attachment site. In some embodiments, removably attaching the textile to the jig frame comprises attaching the textile to the one or more pin attachment sites such that the first jig insert is located adjacent to the one or more pin attachment sites.
[0101] In some embodiments, method 800 further comprises applying one or more post-processing steps to the textile while the textile is attached to the jig frame. For example, the textile, while secured to the jig frame, may be subjected to heating, steaming, pressing, printing, embroidering, chemical application, attaching various components (e.g., cables, laces, indicators) , or other manipulations. For example, the textile may be steamed to alter physical characteristics of some portions of the upper (e.g., to melt fusible materials) , to soften yarns in the textile, and / or to smooth portions of the textile. In some embodiments, method 800 further comprises removing the first jig insert. Removing the first jig insert may be done while the textile is attached to the jig frame via pin attachment sites. In some embodiments, the first jig insert may be removed subsequent to heat or steaming application but before the textile has cooled off. In other embodiments, the first jig insert may be removed from the jig frame in conjunction with removing the textile from the jig frame and subsequently removed from the tunnel of the textile. In some embodiments, the textile comprises an upper that is secured to a sole of an article of footwear at a biteline. In such embodiments, the first knitted tunnel may provide a clean edge for strobel stitching.
[0102] In some embodiments, waste yarn may be included in the textile that can be removed at a later time. For example, waste yarn may be included that is attached at one or more pin attachment sites, which may aid in someone being able to quickly identify the location of the pin attachment sites when placing the textile on the jig frame. Additionally, in some aspects, portion (s) of the textile may be formed (e.g., knit) with waste yarn immediately adjacent location (s) of the textile where a seam. For example, FIG. 2 illustrates waste yarn portions (in solid white) forming the two ends of the textile 150 in the heel region 112 and in the midfoot region 111 on the medial side 115. These waste yarn portions include apertures for pin attachment sites 140 to help fully secure the textile 150 to the jig frame 102. After the textile 150 is processed on the jig frame 102, the waste yarn portions may be removed to create two edges that will be joined to form a seam. The waste yarn portions provide a temporary structure for the pin attachment sites instead of forming openings in the portion of the textile 150 that will eventually form the seam. In this way, any visible deformations from the pin attachment sites or apertures for the pin attachment sites are in a temporary structure and not part of the finished upper.
[0103] Some aspects of method 800 may further include forming the textile into the shape of an upper. Further, method 800 may include incorporating the upper into an article of footwear, such as by attaching a sole structure to the textile.
