Abstract
A device for the ultrasonic welding of two films of plastic includes a sonotrode (2), which can be induced to undergo torsional ultrasonic vibrations by means of exciters (23, 24). The sonotrode (2) has a slit (4), in which an engaging element (5) of an anvil (3) is inserted, so that a welding gap for the two films of plastic (11, 12) is formed. To achieve a welded joint, the films are guided through the welding gap.
