ABSTRACT:
Disclosed is a method and apparatus for forming packages from continuous folded sheets. A sheet is folded and formed into bags by bonding and cutting. Prior to the formation of the bags, plates are introduced between the sheets. The plates are mounted so that they can separate from one another to open the bags after the bags have been fully formed, so that the material can be introduced into the bags. Instead of plates, the elements for opening the bags can be wires, suction elements or blowers.
