The invention relates to an ultrasonic welding device for welding foil-like materials and includes an ultrasound sonotrode, an anvil, an adjusting unit for adjusting a relative position between the ultrasound sonotrode and the anvil, and a regulating unit which regulates, via the adjustment unit, a width of a working gap between the ultrasound sonotrode and the anvil. The anvil is mounted to be movable with respect to the ultrasound sonotrode on a movable mounting. The adjusting unit has a first wedge element connected to the anvil, a second wedge element, and an actuator. The actuator is connected to the second wedge element, and the second wedge element moves relative to the first wedge element to execute a position change of the anvil relative to the ultrasound sonotrode. |
