DEVICE FOR CUTTING CONTINUOUSLY MOVING ZIPPER

摘要

The apparatus provides a cutting device, particularly adapted for cutting a moving length of zipper material in the manufacture of reclosable packages. Upper and lower opposed stationary blades are provided thereby providing opposed cutting edges. A reciprocating blade, with upper and lower cutting surfaces, reciprocates within a slot immediately adjacent to the stationary blades, thereby allowing the reciprocating blade to cut on both its upward and downward reciprocating strokes.
