ABSTRACT:
When manufacturing bags from tubular paper sections of a single layer or multiple layers, at least one end of each flat, tubular section is expanded into a bottom square. Lateral flaps formed in this way are folded such that they overlap and partially cover corner flaps. In order to easily bond expanded bottom squares together, the regions of the tubular sections which are to be bonded together are provided with coatings of thermoplastic which are heated and pressed together.
