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.

System and method for the measurement of repetitive patterns

In accordance with one disclosed embodiment, a continuous steel belt passed around two pulleys which are disposed so that the belt is in contact with a magnetic strip bonded to the surface of a conveyor. A rotary measuring device, such as photoelectric encoder, is attached to the shaft of one of said pulleys and the output signals from the encoder provide an accurate measurement of the linear travel of the conveyor.
