A method of manufacturing an article may include positioning a first textile sheet against a second textile sheet and reciprocating a single needle of an embroidery machine through the first textile sheet and the second textile sheet, the needle forcing fibers of the second textile sheet through the first textile sheet. The fibers may have terminal ends extending outward of an exterior side of the first textile sheet through which the fibers are forced. A method may include forcing fibers from a second side to an opposite side of a single textile sheet to create a pattern of the fibers on the opposite side. Various articles such as footwear uppers may be manufactured according to the method.

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.

Manufacturing of a shoe or a portion of a shoe is enhanced by executing various shoe-manufacturing processes in an automated manner. For example, shoe parts may be retrieved and temporarily assembled according to preset relative positions to form part stacks. The part stacks may be retrieved with the relative positioning of the shoe parts being maintained and placed at a stitching machine for more permanent attachment via stitching of the parts to form a shoe assembly. Movement during stitching of a conveyance mechanism that transfers the part stack from the stacking surface to the stitching machine and movement of a needle associated with the stitching machine may be controlled by a shared control mechanism such that the movements are synchronized with respect to one another. Vision systems may be leveraged to achieve movement and position information between and at machines and locations.

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.

Presses are usable to press bond footwear in press chambers lined with an elastic press membrane shaped like the footwear. The press chamber can be held at negative, neutral, and positive pressure, causing the press membrane may to seat evenly to either the press chamber walls or against the footwear for bonding. When at neutral pressure, the press membrane follows the interior contours of the press chamber but is separated from the same, partially compressing the footwear fitted inside. In this way an operator must easily negotiate the footwear into the membrane through an opening in the same but cannot simply throw the footwear into the membrane. The various pressures may be achieved with a pressure source feeding in to the press chambers and may be cycled between an open, vacuum configuration for insertion, neutral holding position, and closed compressed configuration for bonding.

A method for assembling shoe components includes the steps of: providing at least two shoe components, a shoe last and a film unit; placing the at least two shoe components on an outer surface of the shoe last; removably covering an assembly of the at least two shoe components and the shoe last with the film unit such that the film unit and the shoe last cooperatively define a confining space therebetween; and pumping air out of the confining space and heating the at least two shoe components to shrink and deform the film unit so as to press the at least two shoe components to adhere tightly to each other.

A low-pressure operation conforming membrane for manufacturing an article of footwear includes a perimeter portion having a thickness in a range of 1 to 15 millimeters forming an outer perimeter of the conforming membrane. The conforming membrane also includes a transition portion having a thickness in a range of 1 to 4 millimeters between a first surface and a second surface with the transition portion extending interior to the outer perimeter. The conforming membrane also includes a conforming portion extending from the transition portion in a direction of the second surface and forming a receiving cavity, the conforming portion having a thickness in a range of 1 to 4 millimeters. The perimeter portion, the transition portion, and the conforming portion are a unitary construction comprising a common material composition.

Manufacturing and assembly of a shoe or a portion of a shoe is enhanced by automated placement and assembly of shoe parts. For example, a part-recognition system analyzes an image of a shoe part to identify the part and determine a location of the part. Once the part is identified and located, the part can be manipulated by an automated manufacturing tool.
