Abstract
The apparatus and method uses grooved rollers and a grooved guide plate to position zipper segments on a web. The web is subsequently formed into a cylinder in a form fill and seal apparatus and seal bar assemblies form the bottom transverse seal, the web is indexed and the cylinder is filled, and the seal bar assemblies form the top transverse seal simultaneously with the bottom transverse seal of a subsequent bag. A zipper seal bar completes the sealing of the zipper segment to a second side of the web and a knife extends from a slot in a seal bar assembly to separate the completed bag from the web. This apparatus and method is particularly adapted to narrow zipper segments.
