A last for forming an upper of an article of footwear includes a first portion including a lateral side and a medial side that opposes the lateral side, and a second portion connected with and extending upward and transversely outward in an angled manner away from the first portion such that a terminal end of the second portion is distanced from the first portion. An exterior surface of the last can include a plurality of three dimensional structural surface components disposed over at least 50% of the exterior surface of the last.

A method for forming a plate includes attaching a first strand portion to a flexible substrate to form a first layer on the substrate and positioning a second strand portion on the first layer to form a second layer on the first layer in a plurality of discrete regions on the substrate. The method also includes positioning a plurality of traction elements into corresponding cavities formed into a first mold surface and positioning the substrate on the first mold surface to change a shape of the substrate. At least one of heat and pressure is applied to the first strand portion, the second strand portion, the substrate, and the traction elements to conform the substrate to the shape of the first mold surface and form the traction elements into the substrate at each of the discrete regions. The method also includes incorporating the substrate into an article of footwear.

A method of forming a traced element is disclosed. The method may include printing layers of a traced element and incorporating a textile strand in overlapping polymer layers of the traced element. In some embodiments, the traced element may be formed on a base layer. The traced element may be incorporated into an upper for an article of footwear.

A method for manufacturing a sole structure involving supplying at least one textile sole element having an outer face, including one or more at least partially hot-meltable filament(s); placing the at least one textile sole element in a mould structure including a sole cavity intended to come into contact with the outer face of the textile sole element; placing an inflatable bladder in the mould structure and inflating the inflatable bladder to press the outer face of the textile sole element either directly or indirectly firmly against the sole cavity and heating the textile sole element to melt the at least partially hot-meltable filament(s) and mould the sole cavity onto the outer face of the sole element; obtaining a sole structure including a thermally compressed textile sole element.

Systems and processes for thermoforming an article and for preparing an article for thermoforming are disclosed. The system for thermoforming can include one or more heating stations and a cooling station. The system for thermoforming can further include an article movement mechanism that can couple to an article and rotate the article inside a heating chamber, inside a cooling chamber, or both. The system for preparing an article for thermoforming can include a vessel that comprises a port, and a negative pressure generation system coupled to the port. The system for preparing an article for thermoforming can further include a compression material that forms an interior portion for receiving an article. The negative pressure generation system can cause the compression material to expand to allow for insertion of the article into the interior portion of the compression material.

A plate for an article of footwear includes a base layer, a first strand layer, and a second strand layer. The base layer has a peripheral edge defining a medial side and a lateral side extending between a heel region and a forefoot region. The first strand portion is attached to the base layer via first stitching that crosses over the first strand portion and penetrates the base layer at first attachment locations that are spaced apart from the first strand portion. The first strand portion further includes adjacent segments that form a first layer on the base layer. The second strand portion is disposed on the first layer to form a second layer on the first layer and is attached to the base layer via second stitching.

Articles of wear having one or more textiles that include a low processing temperature polymeric composition and a high processing temperature polymeric composition, and methods of manufacturing the same are disclosed. The low processing temperature polymeric composition and the high processing temperature polymeric composition can be selectively incorporated into a textile to provide one or more structural properties and/or other advantageous properties to the article. The textile can be thermoformed to impart such structural and/or other advantageous properties to the article of wear. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

Upper components for footwear include: (a) a first layer including a first filament including first plural, non-intersecting, spaced apart path segments (wherein the first filament may have a width dimension of less than 3 mm wide); and (b) a second layer including a second filament including second plural, non-intersecting, spaced apart path segments (wherein the second filament may have a width dimension of less than 3 mm), wherein the second layer is fused to the first layer at locations where the layers contact one another. Additional layers of material, including additional layers with filament, may be included in the upper. The filament material in the different layers may be the same or different from one another (e.g., a thermoplastic material, a thermoplastic polyurethane material, a hydrophobic material, a water-repelling material, a non-water absorbing material, etc.). One or more layers each may be formed as a continuous extruded path of filament.

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.

A method for manufacturing three-dimensional items with flexible walls is provided, by method of a mold and counter-mold between which a volume corresponding to that of the item to be obtained is delimited. The item is made up of laminar parts which are mounted on a template that is fixed to the inner surface of the mold. The laminar parts are joined to one another by means of a material which is injected in molten state through a network of conduits delimited between the counter-mold, template and the facing edges of adjacent laminar parts. The template is made of an elastically deformable material and has a three-dimensional configuration.
