A system for inspecting an upper of a shoe includes an optical sub-system and a processor. The optical sub-system captures an image related to a work piece which includes the upper and a last so as to output image data representing the image. The processor receives the image data, establishes a work piece model that is a three-dimensional model of the work piece based on the image data, obtains a cross section of the work piece model, obtains an entry of section data related to the cross section of the work piece model, and compares the entry of section data and an entry of predetermined standard data so as to generate a result of inspection indicating whether the upper is normal.

This is a patent application for an X stitching method, specifically intended for the assembly of uppers by the system known as tied stringstringlaster, with particular application in the footwear segment. The invention includes application to an upper (1), for full assembly of shoes, using string traction (2) as the responsible element for closing the edges of this upper (1), against the mold (3); with the overlock type stitching hereby used as an example of realization.

The present invention relates to a method for manufacturing a shoe upper, including the steps of: providing at least one stretchable portion on the shoe upper; stretching the at least one stretchable portion of the shoe upper for adapting a size of the shoe upper; and permanently attaching at least one rigid element at least partly on the stretched stretchable portion so that the stretched stretchable portion is locked.

A method for automatically pulling a shoe upper onto a last using a robot which includes a robot controller, a robot arm controlled automatically by the robot controller, and a gripper which is moved by the robot arm and which is designed to hold a shoe upper.

In one aspect, the present disclosure provides a method. The method may include placing an upper on a last, where the upper includes a lower perimeter edge secured to a lasting element, and where the last includes an opening for receiving the lasting element. The method may further include feeding the lasting element at least partially through an opening of the last and tensioning the lasting element to tighten the upper around the last by pulling the tensioning element at least partially through the opening.

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 of making an article of footwear may include applying an environmental pressure differential across a sheet of upper material to conform the sheet of upper material to a portion of a footwear last, thereby forming at least a portion of an upper of the article of footwear. In addition, the method may include assembling the article of footwear including fixedly attaching the upper of the article of footwear to a sole structure.
