Abstract: An apparatus and method for manufacturing a bag with a reclosable zipper includes feeding an elongated sheet of bag film in a first direction under a placement head. A zipper assembly is fed in a second direction substantially perpendicular to the first direction into the placement head, and the segment of the zipper assembly in the placement head is cut off. Rollers may be used to retain the zipper segment in the placement head. The placement head, with the zipper segment, is moved adjacent the bag film. The bag film is then compressed between a hot sealing bar and a resilient portion of the placement head to seal the zipper segment to the bag film. Then the bag film is folded over the zipper segment, sealed along a bottom and rear seam, and sealed to the other side of the zipper segment.
