ABSTRACT:
The present invention provides an apparatus and method for loading articles into bags formed from a known roll of web material delineated by perforations at desired intervals. The web includes a first and second sheet of material. A sensor detects a perforation line and activates a sheet separator which opens or tears only the first sheet along a perforation line. The second sheet remains intact and preserves the web. A stream of air is directed at the open edge to inflate a bag. The bag is stabilized on a platform while articles are inserted. After articles are loaded, the second sheet is separated so that the bag is removed from the web and can be closed as desired.
