APPARATUS FOR FEEDING AND BRINGING TOGETHER A WEB OF PACKAGING MATERIAL AND A TEAR-STRIP WEB

摘要

A tear strip is caused to move synchronously with a moving web of packaging material and the web and strip are brought into contact for subsequent joining to define a packaging material with integral tear strip. Contact between the packaging material and tear strip is effected at the surface of a rotating feed roller and a friction drive is employed to cause a supply reel for the tear strip to rotate synchronously with the feed roller.
