ABSTRACT:
In order to provide for the secure and orderly storage of flat objects on a carrier web, in particular unfilled plastic bags on a plastic carrier web, the invention provides a method and an apparatus for the sequential delivery of preformed plastic bags having a unilaterally extending attachment flap. The bags are delivered onto a moving carrier web also made of plastic film. Various alignment and positioning devices place the plastic bags seriatim on the carrier web while a heat-welding mechanism attaches the flap of each bag to the carrier web in a predetermined region. A tear line or perforation line permits subsequent removal of the bag from the web while the flap remains attached thereto. The apparatus includes power sources for the cyclic actuation of the alignment and welding mechanism in synchronism with the speed of delivery of the bags to and from the machine. The apparatus also includes a reciprocating storage container permitting the zig-zag layered stacking of the web with the attached bags.
