Digital bite line creation for shoe assembly

摘要

A system and method may simultaneously apply a limited visibility bite line to a temporarily assembled shoe upper and shoe sole while also generating a digital bite line. The digital bite line may be used to generate a tool path for the application of adhesives to the shoe upper and/or to the shoe sole assembly to permanently assemble the shoe. The limited visibility bite line may comprise a mark or other indicia observable only under specific viewing conditions and/or only for a limited amount of time or until removal. The limited visibility bite line may be used for quality control check purposes to verify, for example, the proper application of adhesives or the proper assembly of the shoe. The limited visibility bite line may be unobservable to the ultimate purchaser and/or wearer of the shoe.

主权项

1. A system for generating a bite line during the assembly of a shoe, the system comprising:
a rotatable table that revolves at a known rate while retaining a shoe sole assembly with a lasted shoe upper pressed into the shoe sole assembly with a predetermined force; a stylus that contacts the shoe upper at a junction line between the lasted shoe upper and the shoe sole assembly while the shoe upper is pressed into the shoe sole assembly with the predetermined force and while the lasted shoe upper and shoe sole assembly are rotated at the known rate; and a computing system operable to receive a plurality of measurements taken during the rotation of the shoe upper and the shoe sole assembly, the plurality of measurements corresponding to the location of the stylus in contact with the junction line at a plurality of times, and further operable to generate a digital bite line corresponding to the received plurality of measurements.
