Efficient Die Cutting Pattern For Footwear Manufacture

摘要

A cutting die for cutting a plurality of parts of an article of footwear from a bulk material. The cutting die includes a first cutting member that cuts a first part of the article of footwear from the bulk material. The cutting die also includes a second cutting member that cuts a second part of the article of footwear from the bulk material. The second cutting member is fixed to the first cutting member to cut the first and second parts together with a single stroke of the cutting die relative to the bulk material. The first and second parts are separate and distinct from each other and have different shapes.

主权项

1. A method of manufacturing an upper of an article of footwear comprising:
providing a cutting die; cutting a first group of parts from a first area of a bulk material during a first stroke of the cutting die, the first group including a first part and a second part of the upper, the first part and the second part being separate and distinct from each other and having different shapes, the first part and the second part cut along a common internal cutting line that defines a first edge of the first part and a second edge of the second part; and cutting a second group of parts from a second area of the bulk material during a second stroke of the cutting die, the second group including a first part and a second part, the first part of the second group corresponding in shape to the first part of the first group, the second part of the second group corresponding in shape to the second part of the first group, the second group cut along a common external cutting line that defines a first boundary of the first group and a second boundary of the second group, the first boundary having a first curvature, and the second boundary having a second curvature that is inverse to the first curvature.
