Title: Bag Mouth Closure ABSTRACT A reclosable plastic film bag mouth closure includes bag mouth lips projecting beyond a heat-seal band closing the bag mouth and a stiffening patch bonded to the interior or exterior of a bag mouth lip between the heat-sealing band and the bag mouth end. The patch is of a length transversely of the heat-seal band so that it and the bag lips can be folded in two return bends for holding the bag mouth closed. The stiffening patches for the reclosable bag mouth end can be applied to a strip of sheet material for making bags at the time that the bags are formed and filled by clipping from a strip of patch-making material patch pieces having pressure-sensitive adhesive on one side. Such patch pieces are transferred from a clipper onto the bag-making material by a revolving transfer member having a suction pick-up to pick up a patch piece and blowing means for subsequently detaching the patch piece from the transfer member and depositing it onto the strip of bag-making material.
