ABSTRACT:
A former allows rectangular tubes of material to be quickly formed for creating bags having rectangular cross sections. The former provides a transition between a round former and a rectangular former so that the material used to form the bag is initially wrapped into a tube around a round former so that the material does not tear on the corners of the former. The round tube of material is then drawn down over the former of the invention to change the round tube to a rectangular tube that may be formed into the bag.
