ABSTRACT:
In making a reclosable plastic film bag, bag mouth lips are formed projecting beyond a heat-seal band closing the bag mouth and a stiffening patch is bonded to the interior or exterior of a bag mouth lip between the heat-sealing band and the bag mouth end. 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 a blow subsequently detaches the patch piece from the transfer member and deposits it onto the strip of bag-making material.
