A tool path for treating a shoe upper may be generated to treat substantially only the surface of the shoe bounded by a bite line. The bite line may be defined to correspond to the junction of the shoe upper and a shoe bottom unit. Bite line data and three-dimensional profile data representing at least a portion of a surface of a shoe upper bounded by a bite line may be utilized in combination to generate a tool path for processing the surface of the upper, such as automated application of adhesive to the surface of a lasted upper bounded by a bite line.

A method for automated manufacturing of shoe soles comprises the steps of: loading a transfer device with at least one outsole element and at least one supporting element, positioning the loaded transfer device adjacent a first part and a second part of a sole mold, transferring the at least one outsole element from the transfer device to the first part and transferring the at least one supporting element from the transfer device to the second part of the sole mold, filling the sole mold with a plurality of individual particles, and applying a medium to bond and/or fuse the particles with each other and with the at least one outsole element.

An example system to measure strain in an article includes a camera, a processor, and memory. The camera is to capture a plurality of images of the article. The processor and the memory are in selective communication with the camera. The processor and the memory are configured to determine strain in a region of the article based on a plurality of reference marks shown in the plurality of images.

A gaging apparatus and method for automation of a shoemaking process are provided for automating a shoemaking process. According to the method, the gaging apparatus obtains operation data according to the gaging process of drawing a gaging line on a boundary between the upper and the sole for shoe manufacturing, and generates trajectory data for the boundary based on the operation data. Based on the trajectory data, the gaging apparatus generates robot trajectory data for performing a buffing and bonding process after the gaging process and transmits it to a shoemaking robot.

A shoe fit measuring device, comprising: a replica human foot portion; pressure sensors; and distance gauges. The pressure sensors and distance gauges are configured to determine whether shoes being fit tested are the correct size. The replica human foot and the sensors may be configured to be inserted into the shoes being fit tested so that fit measurements may be taken.

A method for locating critical control points on a part or combination of parts during a manufacturing process involves mating, directly or indirectly, a jig extension to the part or parts. A pattern on the jig extension defines an origin point that is used to track the position of the part or parts during manufacturing, such as during location-sensitive operations. The jig extension may be a shoe last extension which connects to a shoe or shoe component via a shoe last.

Manufacturing of a shoe is enhanced by creating 3-D models of shoe parts. For example, a laser beam may be projected onto a shoe-part surface, such that a projected laser line appears on the shoe part. An image of the projected laser line may be analyzed to determine coordinate information, which may be converted into geometric coordinate values usable to create a 3-D model of the shoe part. Once a 3-D model is known and is converted to a coordinate system recognized by shoe-manufacturing tools, certain manufacturing steps may be automated.
