METHOD AND APPARATUS FOR THE DESIGN AND MANUFACTURE OF FOOTWEAR

摘要

A method of deriving patterns for shoe manufacture, whereby leather pieces can be cut in accordance with the derived patterns for making the shoes. The method consists in using a computer to operate on three-dimensional co-ordinate information concerning (a) the shape of the shoe last and (b) the shape of style lines to produce three-dimensional co-ordinate information which is subjected to a grading program. The grading program produces three-dimensional co-ordinate information for different sizes which may be displayed in three-dimensional form and possibly modified. The individual graded co-ordinate information for each size is subjected to a flattening program to produce respective patterns.
