Abstract
A method and apparatus for reducing, capturing and disposing of the waste start up web of paper in high-speed manufacturing procedures which involve a converting step, e.g. laser perforation or the like. Specifically, the converting apparatus and the web speed are carefully and precisely controlled by a programmable logic controller to result in a rapid production of converted web with a minimum of waste. The apparatus and method are tuned by sampling the waste and web for conversion quality, and using that information to adjust the converting apparatus and bias that adjustment for maximum reduction in waste.
