Fundamentals
[001]Knitting components have a wide range of knitted structures, materials and properties that can be used in a variety of products. As examples, knitting components can be used in apparel (eg, shirts, pants, socks, jackets, underwear, shoes), athletic equipment (eg, golf bags, baseball and soccer gloves, ball restraint structures for football), containers (eg backpacks, bags), and upholstery for furniture (eg chairs, sofas, car seats). Knitting components can also be used in bed covers (eg sheets, blankets), table covers, towels, flags, tents, candles and parachutes. Knitting components can be used as technical textile material for industrial purposes, including structures for automotive and aerospace applications, filter materials, medical textile materials (eg bandages, cotton swabs, implants), geotextile material for ravine reinforcement, agrotextile material for crop protection, and industrial clothing that protects or insulates against heat and radiation. Accordingly, knitting components can be incorporated into a variety of products for personal and industrial purposes. Invention Summary

[0019] The following discussion and attached figures describe various concepts associated with knitting component union. Composite Element Configuration
[0020] A composite element 100 is shown in Figures 1 and 2 as including a knitting component 110 and a bonded component 120. Components 110 and 120 are secured together through knitting component bonding. Although described in greater detail below, knitting component bonding generally includes using a meltable material (eg, a thermoplastic polymeric material) within knitting component 110 to form a thermal bond that joins or otherwise secures components 110 and 120 together. That is, the bonded component 120 is thermally bonded to the knitting component 110 with the castable material of the knitting component 110. The various composite element 100 configurations discussed below provide examples of general configurations in which the knitting component union can be implemented. As such, the various configurations of composite element 100 can be used in a variety of products, including many of the products discussed in the Background above. In order to provide specific examples of the way in which knitting component joining can be implemented, however, various articles of clothing, including a shirt 200 and an article of footwear 300, are described below.
[0021] The knitting component 110 is manufactured through a knitting process to have a generally flat configuration that defines a first surface 111 and an opposing second surface 112. The knitting process forms the knitting component 110 from a non-fusible yarn 113 and a fusible yarn 114, as shown in Figure 3. That is, the knitting component 110 has a knitted structure in which yarns 113 and 114 are mechanically manipulated together during the knitting process. Various types of knitting processes can be used to form the knitting component 110, including hand knitting, flat knitting, wide tube circular knitting, narrow tube circular knitting jacquard, singular knitting circular knitting jacquard , double knit circular knitting jacquard, weft knitting, weft knitting raschel, and double needle bar raschel, for example. Furthermore, any knitting process that can form a knitted structure from at least two yarns (eg yarns 113 and 114) can be used to manufacture the knitting component 110.
[0022] While the non-fusible wire 113 is formed from a non-fusible material, the fusible wire 114 is formed from a fusible material. Examples of non-melting materials include various thermosetting polymeric materials (eg, polyester, acrylic) and natural fibers (eg, cotton, silk, wool). When subjected to moderate levels of heat, thermosetting polymer materials tend to remain stable. Furthermore, when subjected to high levels of heat, thermosetting polymer materials and natural fibers can burn or otherwise degrade. Examples of meltable materials include various thermoplastic polymeric materials (eg, polyurethane, polyester, nylon). In contrast to thermosetting polymer materials and natural fibers, thermoplastic polymer materials melt when heated and return to a solid state when cooled. More particularly, thermoplastic polymeric materials transition from a solid state to a softened or liquid state when subjected to sufficient heat, and then thermoplastic polymeric materials transition from a softened or liquid state to a solid state when sufficiently cooled. In some configurations, the non-fusible material used for the non-fusible wire 113 may also be a thermoplastic polymeric material, particularly where the melt temperature of the thermoplastic polymeric material used for the non-fusible wire 113 is greater than the melting temperature. of the thermoplastic polymeric material used for the fusible wire 114.
[0023] Thermoplastic polymeric materials, as discussed above, melt when heated and return to a solid state when cooled. Based on this property, the thermoplastic polymeric material of meltable yarn 114 can be used to form a thermal bond that joins knitted component 110 and bonded component 120. As used herein, "thermal bonding" or variations thereof is defined as a technique of spinning between two components which involve a softening or melting of a thermoplastic polymeric material within at least one of the components so that the components are secured together when cooled. Similarly, the term "thermal bond" or its variations is defined as the bond, connection or structure that joins two components together through a process that involves a softening or melting of a thermoplastic polymeric material within at least one of the components. so that the components are secured together when cooled.
[0024] As general examples, thermal bonding may involve (a) the melting or softening-cement of thermoplastic polymeric materials into two components so that the thermoplastic polymeric materials interlace with one another (e.g., diffuse through a boundary layer between thermoplastic polymeric materials) and are held together when cooled; (b) melting or softening a thermoplastic polymeric material within a first component so that the thermoplastic polymeric material extends into or infiltrates the structure of a second component to lock the components together when cooled; and (c) melting or softening a thermoplastic polymeric material within a first component so that the thermoplastic polymeric material extends into or infiltrates cavities of a second component to lock the components together when cooled. As such, thermal bonding can occur when two components include thermoplastic polymeric materials or when only one of the components includes a thermoplastic polymeric material. Additionally, thermal bonding does not generally involve the use of stitching, adhesives or other bonding techniques, but involves direct bonding of components together with a thermoplastic polymeric material. In some situations, however, stitching, adhesives or other bonding techniques can be used to supplement thermal bonding or bonding components through thermal bonding.
[0025] More specific examples of thermal bonding that refer to the composite element 100 will now be discussed. In general, bonded component 120 can be any element that is bonded to knitting component 110, including textile elements (e.g., knitted textile elements, woven textiles, non-woven textiles), polymeric sheets, polymeric foam layers, elements leather or rubber, and plates, for example. In a configuration where bonded component 120 is formed from a textile element, thermal bonding may involve melting or softening a thermoplastic polymeric material within meltable yarn 114 so that the thermoplastic polymeric material extends into the bonded component textile element 120 and around individual filaments, fibers or yarns within the textile element to secure components 110 and 120 together when cooled. In a similar configuration where bonded component 120 is formed from a textile element incorporating a thermoplastic polymeric material, thermal bonding may involve the melting or softening of thermoplastic polymeric materials within each fusible yarn 114 and the textile element of the bonded component 120 so that the thermoplastic polymeric materials interlace with one another and are held together when cooled. Furthermore, in any configuration where bonded component 120 incorporates a thermoplastic polymeric material (e.g. textiles, polymeric sheets, polymeric foam layers, leather or rubber elements, boards) the thermal bonding may involve the melting or softening of thermoplastic polymeric materials within each fusible wire 114 and bonded component 120 so that the thermoplastic polymeric materials intertwine with one another and are secured together when cooled. Additionally, in a configuration where the bonded component 120 is a polymeric sheet, a polymeric foam layer, a leather or rubber element, or board, the thermal bonding may involve the melting or softening of a thermoplastic polymeric material within the fusible wire 114 so that the thermoplastic polymeric material extends into bonded component cavities 120 to hold components 110 and 120 together when cooled. Although many composite member 100 configurations do not involve the use of stitching, adhesives, or other joining techniques, these joining techniques can be used to supplement thermal joining or joining components 110 and 120 through thermal joining.
[0026] Based on the above discussion, knitting component bonding generally includes using a fusible material (e.g., a thermoplastic polymeric material) within fusible yarn 114 of knitting component 110 to form a thermal bond which joins or otherwise secures the components 110 and 120 together. That is, the bonded component 120 is thermally bonded to the knitting component 110 with the fusible material of the fusible yarn 114. In order to form the thermal bond, the fusible material is often located in one part. of the knitting component 110 which is adjacent to the bonded component 120. Since that bonded component 120 is secured to the first surface 111, therefore, the castable material is often located on the first surface 111 to thereby form a thermal bond with the bonded component 120 on the first surface 111. Referring to Figure 3, the non-fusible yarn 113 effectively extends throughout the knitting component 110 and from the first surface 111 to the second surface 112, whereas the fusible yarn 114 is concentrated on the first surface 111. In this configuration, the fusible material of the fusible wire 114 is positioned to contact the bonded component 120 and form the thermal bond between the components 110 and 120 on the first surface 1 11. Any knitting structure where a yarn (eg, 114 fusible yarn) is concentrated or is present on one or both surfaces can be used to achieve this configuration.
[0027] Although configuration 3 provides a structure suitable for forming a thermal bond between components 110 and 120, a variety of other knitted structures can also form a thermal bond. Referring to Figure 4A, for example, the non-fusible yarn 113 effectively extends throughout the knitting component 110 and from the first surface 111 to the second surface 112, while the fusible yarn 114 is concentrated on both surfaces 111 and 112. As another example, Fig. 4B shows a configuration in which the fusible wire portion 114 located on the first surface 111 is coated with a non-fusible wire portion 113. That is, the wires 113 and 114 run parallel along. of the first surface 111. Another configuration in which yarns 113 and 114 are coated is shown in Figure 4C, where yarns 113 and 114 run in parallel throughout the knitting component 110. Accordingly, yarn configurations 113 and 114 within of knitting component 110 can vary considerably.
[0028] Referring again to Figure 3, the fusible wire 114 is concentrated on the first surface 111 and forms loops that extend around sections of the non-fusible wire 113. A consideration regarding this configuration concerns the potential for release or release . When heated, the thermoplastic polymeric material of the fusible yarn 114 can soften or melt, which can effectively release the non-fusible yarn sections 113. That is, the melting or softening of the thermoplastic polymeric material of the fusible yarn 114 can enable the knitted structure of knitting component 110 comes loose, becomes non-cohesive, or otherwise releases as fusible yarn 114 is no longer forming loops that hold the knitted structure together. In order to prevent this occurrence, the configurations of figures 4B and 5C can be used. That is, wires 113 and 114 can be coated so that they run in parallel. When the fusible yarn 114 softens or melts, therefore, the non-fusible yarn 113 remains intact and effectively retains the knitted structure together.
[0029] An additional method to ensure that the melting or softening of the thermoplastic polymeric material in the fusible yarn 114 does not release the knitted structure is to form fusible yarn portions 114 from both the fusible and non-fusible materials. Referring to Figure 5A, for example, a portion of fusible strand 114 is shown as having several fusible filaments 115 and non-fusible filaments 116. Even when fusible filaments 115 melt or soften, non-fusible filaments 116 are present to prevent the knitted structure release. In a similar configuration, Figure 5B shows filaments 115 and 116 as forming a sheath core structure. That is, fusible filaments 115 are located peripherally to form a sheath and non-fusible filaments 116 are located centrally to form a core. Similarly, Figure 5C shows a configuration in which fusible filaments 115 spiral around a core formed by non-fusible filaments 116.
[0030] Another method of ensuring that the melting or softening of the thermoplastic polymeric material in the fusible yarn 114 does not release the knitted structure is to form individual filaments within the fusible yarn 114 from both fusible and non-fusible materials . Referring to Figure 6A, for example, an individual filament 117 includes a fusible portion 118 and a non-fusible portion 119 in a sheath core configuration. That is, the fusible part 118 is peripherally located to form a sheath part and the non-fusible part 119 is centrally located to form a core. In another embodiment, Figure 6B shows filament 117 as having half formed from fusible material 118 and another half formed from non-fusible part 119. Fusible strand 114 can therefore be formed from multiple filaments 117 which they will only melt or partially soften when exposed to heat.
[0031] The configuration of the composite element 100 in Figures 1 to 3 provides an example of the way in which the knitting component joint can be used to join the components 110 and 120. Whereas the knitting component joint can be used in various products, numerous aspects relating to the composite element 100 may vary from the configuration shown in Figures 1 to 3. In addition, variations in any of the components 110 and 120 may change the properties of the composite element 100, thereby improving the products in which knitting component binding is used. Referring to Figure 7A, for example, joined component 120 is shown as having a larger size than knitting component 110. Figure 7B illustrates a configuration in which joined component 120 forms a plurality of openings 121. When the bonded component 120 is a polymeric sheet, polymeric foam element, or plate, for example, apertures 121 can be used to improve the fluid permeability or flexibility of the composite element 100. Although both components 110 and 120 may be thick. constant, one or both of components 110 and 120 may also have a variable thickness. Referring to Figure 7C, for example, the joined component 120 has a tapered configuration. Although both components 110 and 120 may be flat, one or both of components 110 and 120 may also have a contoured configuration. Referring to Figure 7D, for example, components 110 and 120 are curved. In the configurations of Figures 5A and 5C, fusible wire 114 is concentrated on both surfaces 111 and 112. This can provide the advantage of allowing bonded components 120 to be thermally bonded to either surface 111 and 112. For example, Figure 7E shows a configuration in which one bonded component 120 is thermally bonded to the first surface 111 and another bonded component 120 is thermally bonded to the second surface 112.
[0032] In addition to various structural aspects of the different configurations of the composite element 100 shown in Figures 7A to 7E, some configurations of the composite element 100 may provide aesthetic, informational, or other non-structural benefits. Referring to Figure 7F, for example, bonded component 120 is a letter "A" that is secured to knitting component 110 through knitting component bonding. The letter "A" or other markings can be used to print information about a product, such as the manufacturer's trademarks. Similarly, Figure 7G shows the joined component 120 as a scoreboard having care instructions, such as for an article of clothing.
[0033] Referring to Figures 5A and 5C, fusible wire 114 is located on both surfaces 111 and 112. In these configurations, bonded component 120 can be secured to either surface 111 and 112. Referring to Figure 7H, bonded component 120 may also wrap around knitted component 110, thus being bonded to both surfaces 111 and 112. In another configuration, components 110 and 120 may be thermally bonded at their edges, as shown in Figure 7I, in order to replace the seam and form a joint between components 110 and 120. Referring to Figure 7J, a number of wires 133 may be located between and thermally bonded between components 110 and 120. Wires 133 may, for example, resist wear stretch in the directions corresponding to their lengths. As such, the combination of components 110 and 120 and yarns 133 can be used in footwear, for example, as described in U.S. Patent No. 7,770,307 to Meschter, which is incorporated herein by reference.
[0034] An advantage of the composite element 100 is that the properties of both components 110 and 120 combine to improve the overall properties of the composite element 100. In configurations where the joined component 120 is a textile, the joined component 120 may have different properties textiles of knitting component 110. The resulting composite element 100 can therefore exhibit the textile properties of both components 110 and 120. When joined component 120 is a polymeric sheet, joined component 120 can impart resistance to the permeability of fluid or wear resistance. If, for example, the bonded component 120 is formed of a compressible material, such as a polymeric foam element, then the composite element 100 may be suitable for articles of clothing where padding (i.e., attenuation of impact forces) is beneficial, such as padding for athletic activities that may involve contact or impact with other athletes or equipment. Similar protective attributes may be present when the joined component is a board.
[0035] The combination of properties of components 110 and 120 may also be present when methods other than knitting component joining (eg adhesives, sewing) are used to join components 110 and 120. An advantage for joining components knitting component, however, is that no adhesive or other elements are present between components 110 and 120. For example, some adhesives (eg, hot melt) can impair fluid permeability through composite element 100. , adhesives may be visible around the edges of the bonded component 120, thus reducing the aesthetic appearance of a product. Furthermore, stitch formation can be a time-consuming process, the stitches can compress any of the components 110 and 120, and the stitches can be visible from outside the composite element 100. Accordingly, knitting component joining 100 can be used to alleviate the disadvantages discussed above, for example, in other joining methods.
[0036] Fusible yarn 114 may extend through knitting component 110. In addition to detracting from the knitting component bonding advantage, fusible yarn 114 may have the effect of strengthening or stiffening the structure of knitting component 110. More particularly, fusible yarn 114 can also be used to join one part of non-fusible yarn 113 to another part of non-fusible yarn 113, which has the effect of locking or locking the relative positions of non-fusible yarn 113, printing, thus, a resistance to stretch and rigidity. That is, the parts of the non-fusible yarn 113 may not slide relative to one another when fused by the fusible yarn 114, thus preventing permanent warping or stretching of the knitting component 110 due to the relative movement of the knitted structure. Another benefit relates to limiting loosening if a knit component 110 portion becomes damaged or a non-melting yarn portion 113 is cut.
[0037] Although the fusible yarn 14 may extend through the entire knitting component 110, the fusible yarn 114 may be limited to specific areas of the knitting component 110. Referring to Figure 8A, for example, a perspective view The exploded composite element 100 shows the knitting member 110 as having a bonding area 131 and a peripheral area 132. The bonding area 131 corresponds to the portion of the first surface 111 where the bonding element 120 is thermally bonded to the knitting component 110 In addition, fusible wire 114 may be limited to splicing area 131. That is, fusible thread 114 may be absent from peripheral area 132. In some configurations, an advantage can be gained by not splicing a portion of the non-fusible thread 113 the other part of the non-fusible yarn 113 in the peripheral area 132. Accordingly, by placing the fusible yarn 114 in specific areas of the knitting component 110, bonding of the knitting component can be carried out in these areas while re- duces the effects of fusible wire 114 in other areas. A similar configuration is shown in Figure 8B, where a number of joint areas 131 are formed on the part of the first surface 111 where the bonded element 120 is bonded to the knitting component 110. In some configurations, the bonded areas 131 may be stitches where the fusible wire 114 is present and exposed on the first surface 111.
[0038] The knitting component 110 may have a generally flat and continuous configuration. In some configurations, as shown in Figure 8C, the knitted structure of the knitting component 10 may define multiple notches 133 or openings 134. That is, the knitted structure may be knitting to form surface features or other elements by varying the structure knitted in specific places. Alternatively, notches 133 or other surface features can be formed by etching, for example. In addition to improving the aesthetic appearance of the composite element 100, the indentations 133 and the openings 134 can enhance properties such as fluid permeability and flexibility, while reducing the overall mass of the composite element 100.
[0039] Based on the above discussion, the composite element 100 has a configuration in which components 110 and 120 are held together through knitting component union. In general, bonding the knitting component includes using a meltable material (e.g., a thermoplastic polymeric material in meltable yarn 114) within the knitting component 110 to form a thermal bond that joins or otherwise secures the components 110 and 120 each other. The various composite element 100 configurations discussed above provide examples of general configurations in which knitting component bonding can be implemented. As such, the various configurations of composite element 100 can be used in a variety of products to impart a range of benefits to those products. Union Process
[0040]The general process by which the knitting component union is performed will be discussed in detail. As a preliminary aspect of the process, the knitting component 110 is formed through a knitting process. Generally, a knitting machine can be programmed to knit a textile (ie, knitting component 110) with the non-fusible yarn 113 and the fusible yarn 114. In addition, the knitting machine can also locate the fusible yarn 113 in at least a surface, such as the first surface 111. Effectively, therefore, the knitting process may include the concentration of meltable yarn 114 on the first surface 111. In some configurations, the knitting process may also extend the meltable yarn 114 from the first surface 111 to the second surface 112 or board yarns 113 and 114. Hand knitting, rather than machine knitting, can also be used.
[0041] Once the knitting component 110 is formed, both components 110 and 120 can be located within a heat press 140, as shown in Figure 9A. More particularly, bonded component 120 may be located adjacent a portion of first surface 111 where bonding is to take place, and both components 110 and 120 may be located between opposing portions 141 and 142 of heat press 140. Once positioned, the parts 141 and 142 can translate toward each other to compress and apply heat to components 110 and 120, as shown in Figure 9B. That is, components 110 and 120 can be compressed and heated to a temperature that causes the thermoplastic polymeric material in melt wire 114 to melt or soften. Due to the compression of parts 141 and 142, the parts of the molten or softened thermoplastic polymeric material may contact or otherwise engage the bonded component 120. Following sufficient heating and compression, the parts 141 and 142 separate as shown. in Figure 9C, and components 110 and 120 can be removed. After cooling, the thermoplastic polymeric material of meltable wire 114 securely forms a thermal bond that joins components 110 and 120 together.
[0042] Heat press 140 provides an advantage of simultaneously heating and compressing components 110 and 120. In other joining processes, components 110 and 120 can be heated before being compressed into heat press 140 or a cold press . Examples of heating methods that can be used include conduction, infrared, ultrasound, high frequency, radio frequency, vibration heating and steam heating. Product Settings
[0043] Following the knitting component bonding process discussed above, the composite element 100 can be incorporated into one of several products including many of the products discussed in the Fundamentals above. As specific examples of products that can incorporate the concepts associated with knitting component bonding, two articles of clothing, a shirt 200 and an article of footwear 300, will now be discussed.
The jacket 200 is shown in Figure 10 as including a back region 201 and a pair of arm regions 202 extending outwardly from the back region 201. The back region 201 corresponds to a back of a user and covers at least part of the back when used. Similarly, the arm regions 202 correspond to the user's arms and cover at least a portion of the arms when used. The back region 201 and the arm region 202 can both be formed from a textile material that is similar to the knitting component 110. That is, the textile material forming the back region 201 and the arm regions 202 may be at least partially formed from a yarn incorporating a fusible material, which has similar properties to the fusible yarn 114. Furthermore, the fusible material can be oriented to form at least a portion of the outer surface of the jacket 200. The textile material forming the region The back 201 and the arm regions 202 may also be at least partially formed from a yarn incorporating a non-fusible material, which has properties similar to the non-fusible yarn 113.
[0045] According to the jacket 200 configuration discussed above, various components 203 to 205 can be secured to the jacket 200 by knitting component bonding together. With specific reference to Figure 10, two components 203 are attached to the elbow areas of the arm regions 202 and may be polymeric or leather sheets that provide wear resistance to the elbow areas. Component 204 is also located around a neck opening of the back region 201 and may be a polymeric sheet that improves the stretch resistance of the area around the neck opening. Additionally, two components 205 are joined to lateral areas of the back region 201 and can be polymeric foam elements that attenuate the forces that impact the wearer's sides during athletic activities. Accordingly, the general concepts of knitting component bonding can be used in the shirt 200 to imprint a variety of benefits. Furthermore, similar concepts can be applied to a variety of other types of apparel to convey similar benefits, including helmets, pants, underwear, socks, and gloves.
[0046] Another article of clothing, footwear 300, is shown in figures 11 to 13 as including a sole structure 301 and an upper 302. Although the footwear 300 is shown as having a configuration that is suitable for running, the knitting component joining concepts can be applied to a wide range of athletic shoe styles, including basketball shoes, cycling shoes, hiking shoes, football shoes, golf shoes, climbing shoes, and boots, boots for skiing and snowboarding, football shoes, tennis shoes, and hiking shoes, for example. The concepts associated with tribal component union can also be used with shoe styles that are generally considered non-athletic, including evening shoes, moccasins, and sandals. Accordingly, knitting component binding can be used with a wide variety of shoe styles.
[0047] The sole frame 301 is attached to the upper 302 and extends between the foot and the ground when the shoe 300 is worn. In general, the structure of the sole 301 can be of any conventional or non-conventional configuration. The upper 302 provides a framework to securely and comfortably receive a user's foot. More particularly, the various elements of the upper 302 generally define a void space within the shoe 300 for receiving and securing the shoe with respect to the sole structure 301. The surfaces of the void space within the upper 302 are shaped to accommodate the foot and extend over the inside of the foot and toe areas of the foot, along the middle and sides of the foot, under the foot, and around the heel area of the foot. In this configuration, at least one outer surface of the upper 302 may be formed from a textile material similar to knitting component 110. That is, the textile material forming the outer surface may be at least partially formed from a yarn incorporating a fusible material, which has properties similar to the fusible wire 114. Furthermore, the fusible material may be located on at least a portion of the outer surface. The textile material may also be at least partially formed from a yarn incorporating a non-fusible material, which has similar properties to the non-fusible yarn 113.
[0048] According to the configuration of the shoe 300 discussed above, several components 303-306 can be attached to the textile material of the upper 302 through the knitting component union. As an example, component 303 is secured in a forefoot area of the upper 302 and may be a polymeric or leather sheet that forms a wear resistant toe guard extending from a side to a side. middle side of shoe 300. Component 304 is located around a heel region of shoe 300 and extends from the lateral side to middle side of shoe 300 to form a heel support that will resist lateral movement of the foot during walking, running or other ambulatory activities. Although component 304 is secured to the outer surface of upper 302, component 304 can also be secured to the inner surface if a meltable material is present on the inner surface. Various polymeric sheets and plates, for example, can be used for component 304. Component 305 can also be a polymeric or leather sheet that extends around an upper portion opening area 302 to reinforce the openings of shoelace due to tension in a shoelace. Additionally, three components 306 forming the characters "XYZ" are located on the side of the top 302 to represent a trademark or other marking. Accordingly, the general concepts of knitting component joining can be used in Footwear 300 to imprint a variety of benefits.
[0049] In the configuration of footwear 300 described above, the textile material forming the outer surface of the upper 302 is noted as being partially formed from a thread incorporating a fusible material. In the configuration shown in Figures 11 and 13, however, the outer surface of the upper 302 can be a base element formed from any material used in the upper parts of footwear. That is, the outer surface of the top may or may not include a thermoplastic polymeric material. Furthermore, components 303 to 306 may be formed from a textile material incorporating a yarn with a meltable material. In other words, components 303-306 can have the configuration of knitting component 110. As such, the meltable material of components 303-306 can be used to form a thermal bond with the upper 302.
[0050] The invention is described above and in the attached figures with reference to a variety of configurations. The purpose served by the description, however, is to provide an example of various features and concepts related to the invention, and not to limit the scope of the invention. Those skilled in the relevant art will recognize that numerous variations and modifications can be made to the configurations described above without departing from the scope of the present invention as defined by the appended claims.
