Apparatus and method for minimizing waste and improving quality and production in narrow web processing operations by automatic twist defect correction

摘要

Apparatus and methods are provided to minimize waste and improve quality and production in web processing operations. The apparatus and methods provide defect detection in deposition of acquisition material (12), which on current machines frequently flips and is difficult to detect when it has flipped causing manufacturers to scrap thousands of products. Using the present invention, defects are able to be detected by discerning a difference in the appearance from side to side with a vision camera (18), and an acquisition inverter (10) can flip the material (12) to a correct orientation.
