Abstract

A fixed blade in conjunction with a notched rotary blade perforates the platic tubular material for rollers operating at a higher speed to separate the sections in a shearing motion. The welding drum is designed to hold the sections under a partial vacuum while a welding unit seals one end of the section, the open end being gripped and passed to a conveyor. The purpose is to provide a continuous process and replace existing intermittent motions.
