ABSTRACT:
In accordance with one embodiment of the invention, the repetitive bar pattern of plaid material is sampled along the length of the goods by means of light reflected therefrom and auto- and cross-correlation functions of groups of said signals are computed so as to define the pattern of the transverse bars of the plaid. This measured pattern is used within a computer-controlled system for cutting the component pieces of clothing items so as to compensate for nonuniformities or distortions in the bar pattern of the material.
