Abstract
An apparatus and method for perforating a plastic film fleader section connecting together a plurality of plastic film bags and forming a pack of saddle bags. The saddle bags are carried on a block with the header on the block and the bags draped thereover. The block is in sliding engagement with a track and is selectively moved in position in the apparatus. A pair of pivotally connected arms are selectively pivotally moved in contact with the plastic film bags pulling the bags generally away from the header and causing the header to become taut. A pair of perforation blades are forced toward the carrying block and through the header simultaneously creating two perforation lines, one line on each side of the header.
Claims16
An apparatus for perforating a plastic film header section connecting together a plurality of plastic film bags and forming a pack of bags, said apparatus comprising:
- means for carrying the pack of bags at the plastic film header with the plastic film bags draped thereover;
- means for contacting a portion of the pack of bags draped over said carrying means and making said plastic film header section taut on said carrying means;
- and,
- perforation means for partially cutting the plastic film header section and perforating the same, whereby the plastic film bags can thereafter be detached from the header at said perforation by pulling the bags away from the header.
An apparatus for perforating a plastic film header section connecting together a plurality of plastic film bags and forming a pack of saddle bags, said apparatus comprising:
- a carrying block whereover said plastic film bags are draped, said block being in sliding engagement with a track;
- means for moving said block on said track;
- two arms each having a contact pad and adapted for pivotal movement in and out of contact with the plastic film bags, said arms being pivotally movable for selectively making said pads contact a portion of the pack of bags draped over said carring block whereby the plastic film header section is made taut on the carrying block;
- and,
- two perforation blades carried by a means for forcing said blades through the header and simultaneously creating two perforation lines, one on each side of the header.
