An article of footwear with an upper including a ribbon structure is disclosed. The ribbon structure comprises ribbon sections running in at least two different directions. Ribbon sections are connected at nodes that may move substantially independently of other nodes. The ribbon structure can provide strength along one of the directions and may simultaneously remain slack in the other direction.

A method of making an article of footwear with an upper including a ribbon structure is disclosed. The method includes laying down ribbon elements in straight and winding sections. The method includes stitching or otherwise attaching the ribbon elements to a backing layer. The method also includes embroidering a periphery of the ribbon structure to tack down any raised portions of the ribbon at the periphery. The method also includes inserting a lace through loops in the ribbon structure.

An article of footwear with an upper including a ribbon structure is disclosed. The ribbon structure comprises ribbon sections running in at least two different directions. Ribbon sections are connected at nodes. Between nodes portions of ribbon act like links joining the nodes. The links can be arranged in various geometries, including a rectangular grid and a triaxial grid. The ribbon structure may extend the entire length of the article of footwear, and may extend through a forefoot, midfoot and heel.

An article of footwear is configured to be worn so as to at least partially cover a wearer's foot. The footwear includes at least one optical fiber on an internal surface of the footwear. The at least one optical fiber is configured to project radiation having a therapeutic wavelength through the at least one optical fiber and toward at least one of the wearer's foot, ankle or leg when the footwear is being worn so as to at least partially cover the wearer's foot.

An upper for an article of footwear, the upper including a base layer defining a least a portion of the upper and polymer threads stitched to the base layer. The polymer threads may include a core composed of a first material and a coating composed of a second material, where the melting point of the first material is higher than the melting point of the second material. The polymer threads may be bonded to the base layer by the coating of the polymer threads. The polymer threads may include one or more polymer thread sets stitched in pattern(s) on area(s) of an outer surface of the base layer to provide targeted characteristics to area(s) on the upper. In some embodiments, the polymer threads may be bonded to the base layer with heat and/or pressure.

Pattern data for at least two sizes are converted to knit data, regarding knitted products to be graded. Regarding the knit data for at least two sizes, characteristic points specifying shapes of the knitted products and intermediate shapes specifying shapes of the knitted products between the characteristic points are generated. By interpolating or extrapolating the characteristic points and the intermediate shapes, according to a desired size of the knitted products, characteristic points and intermediate shapes for the desired size are generated. Closed loops are generated by connecting the characteristic points and the intermediate shapes, and knit data for the desired size is generated by allocating knitted stitches within patterns specified by the closed loops. Without pattern data for intermediate sizes, knit data for the intermediate sizes are generated from the two size knit data.

A manufacturing process involving a series of discrete operations can be modified by adding, removing, or reordering operations, without design changes to the equipment. The manufacturing process uses a frame comprising one or more alignment tabs. Each alignment tab comprises an alignment element. The alignment element interacts with a corresponding alignment element at a manufacturing station to identify to the manufacturing station the position and orientation of the frame. The frame supports a material in a known position and orientation relative to the frame, allowing the manufacturing station to infer the position and orientation of the pliable material on the frame from the interaction of the alignment elements on the frame and the manufacturing station. The operations at any particular manufacturing station can therefore be positioned independent of what operations, if any, have come before, or in what order.

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.

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.

An article of footwear comprises a sole structure and an upper. The upper is connected to the sole structure to form an enclosure to at least partially receive a foot. The upper comprises a first panel, a second panel, a backing panel and fibers. The first panel and the second panel at least partially form the enclosure. The backing panel is located within the enclosure along surfaces of the first and second panels. The fibers extend from the backing panel and are mechanically embedded in the first and second panels so that at least some of the fibers are partially disposed outside the enclosure.
