ABSTRACT:
A device for manufacturing packing bags from two packaging films, comprising two transport rollers, each of which pulls a film from a respective feed roll. The two films have marks printed on them at regular intervals. The transport rollers are pressed against corresponding idler rollers which between them preferably form a feed gap for the films. Downstream of the two transport rollers, there is at least one first buffer taking up slack in the assemblage of the two films or accommodating the lengths of the two films to match each other. The device can be used to synchronize two films that are printed with a regular pattern so that the patterns match.
