ABSTRACT:
An apparatus is arranged to construct a reclosable zipper attached to a polymeric web. The zipper has a female profile with first and second elongated legs substantially perpendicular to the web and a channel therebetween. The apparatus includes a punch wheel having a first surface for supporting a first portion of the web on a first side of the zipper. The punch wheel includes a plurality of projecting punches for engaging the channel between the first and second legs of the female profile and for exerting a punch force through the first leg to remove slugs from the first leg. The apparatus includes a die wheel adjacent to and coaxially aligned with the punch wheel. The die wheel has a second surface for supporting a second portion of the web on a second side of the zipper and has a plurality of voids for receiving the punches. The punch wheel includes a cam for pushing the punch, and the first and second surfaces are tapered. Each of the punches can have an L-shaped cross section, with a bottom of the L shaped structure engaging the channel.
