ABSTRACT:
Packing machines for the manufacture of packing containers frequently produce these from web-like material, which is supplied to the machine in the form of a roll. During the production the material web is advanced through the machine along a path defined by guiding rollers, guiding rails and similar elements. These guiding elements obstruct in an undesirable manner the movement of the material web through the machine. This difficulty is eliminated in accordance with the invention in that a front and a back part of the material web are advanced alternately. In accordance with the invention, moreover, an arrangement is proposed with first and second web-advancing elements, which operate with alternating working strokes.
