System and method for knitting shoe uppers
11168416 · 2021-11-09 · ·

Systems and methods for manufacturing knitted shoe uppers. An article of fully finished three-dimensionally weft knitted footwear is manufactured through a knitting process which can be performed by an automated V-bed flat knitting machine. The knitting process includes manipulating one or more double-knit stitch types and joining the stitches exclusively in the knitting process to create a seamless upper to fit a foot. A resulting upper advantageously has no sewn seams and requires no manual post process to cut or sew the upper to create the dimensional shape. The process creates a seamless, full gauge, dimensionally stable footwear upper, as a unitary textile construction with an integrated anatomically appropriate heel. The entire upper, including the closure element of the upper, may be completed exclusively by the knitting machine, ready for the following shoe making process.

Article of footwear incorporating knitted components and a receiving strap component
11168417 · 2021-11-09 · ·

An article of footwear provides improved stability and support by incorporating a strap to overlay over an instep area of an upper component that is comprised of a knitted material. The strap includes engagement members on an underside of the strap that engage ribbing structures that are part of the knitted material on an outer surface of the instep area. By engaging with the ribbing structures, the strap provides improved stability and support.

Article of footwear incorporating an embroidered element, and related methods of manufacture

The invention relates to embroidered material portions for incorporation into an article of footwear, and systems and methods for the manufacture thereof. More particularly, the invention relates to an article of footwear having an upper with a sole structure, the upper including a first upper element including a base layer and a first structural layer including at least one first fiber embroidered onto the exterior surface of the base layer, the at least one first fiber forming a plurality of first elongate structural elements extending over the exterior surface of the base layer to provide discrete localized structural support to the base layer.

A yarn or thread may include a plurality of substantially aligned filaments, with at least ninety-five percent of a material of the filaments being a thermoplastic polymer material. Various woven textiles and knitted textiles may be formed from the yarn or thread. The woven textiles or knitted textiles may be thermal bonded to other elements to form seams. A strand that is at least partially formed from a thermoplastic polymer material may extend through the seam, and the strand may be thermal bonded at the seam. The woven textiles or knitted textiles may be shaped or molded, incorporated into products, and recycled to form other products.

VISION-GUIDED STITCHING SYSTEMS AND LOGIC FOR FABRICATING ENGINEERED TEXTILES WITH INTERSTITCHED SUPERPOSED WIRES
20230323578 · 2023-10-12 · ·

Presented are automated manufacturing systems for fabricating engineered textiles, footwear and apparel formed with such engineered textiles, methods for making such engineered textiles, and memory-stored, processor-executable instructions for operating such manufacturing systems. An automated manufacturing system constructs engineered textiles from workpieces composed of superposed, unwoven wires. The system includes a movable end effector bearing a stitching head and an image capture device. The stitching head has a thread feeder and sewing needle to generate stitches. The image capture device captures images of the workpiece and outputs data indicative thereof. A system controller receives this image capture device data and locates, from the captured image of the workpiece, gaps defined between quadrangles of the superposed wires. The controller commands the end effector to sequentially move the stitching head and thereby align the sewing needle with the gaps, and commands the stitching head to insert a succession of stitches within these gaps.

Shoe

An object of the present invention is to provide a shoe having excellent comfort. The present invention provides a shoe including an upper material that is partially or fully formed of a fiber sheet, wherein the fiber sheet exhibits specific tensile characteristics at least in one direction.

POLYOLEFIN-BASED SYNTHETIC LEATHER AND ARTICLES FORMED THEREFROM

A variety of plates for footwear are provided including a polyolefin resin. Sole structures and articles of footwear formed therefrom are also provided. Methods of making the polyolefin resin compositions, plates, sole structures, and articles of footwear are also provided. In some aspects, the polyolefin resin composition includes an effective amount of a polymeric resin modifier. The effective amount can be an amount effective to allow the resin composition to pass a flex test, and in particular to pass a flex test without significant change in abrasion loss. In some aspects, the resin composition also includes a clarifying agent to improve optical clarity of the plate. In some aspects, the plates include a textile disposed on one or both of a first side and the second side of the plate. The textile can provide for improved bonding of the plate to other components such as a chassis or an upper.

FOOTWEAR UPPER INCLUDING VARIABLE STITCH DENSITY

An article of footwear includes a sole and an upper at least partially formed of a textile element. The textile element includes a yarn matrix having a plurality of interlocked strands oriented in predetermined directions. A structural element may be captured within the matrix at selected locations. In operation, the matrix is stitched onto a temporary substrate. The substrate is removed and the article coupled to a sole structure to form the article of footwear.

Shoe with flexible upper
11771177 · 2023-10-03 · ·

The invention is a high heel shoe with an upper that will provide comfort and flexibility for the wearer. In a preferred embodiment the upper consists of two at least two materials: 1) a firm fabric, such as leather, that will hold the shape of the design and have limited flexibility; 2) a flat knitted elastic, such as knit elastic, which will not narrow, or not narrow significantly, when stretched. In addition, the firm fabric is configured to have a flex-point and in a preferred embodiment is formed of two pieces of the firm material having a “split” between them providing the desired flex-point.
