Abstract
The present invention concerns an ultrasonic welding installation comprising an ultrasonic vibration unit having a sonotrode and a converter, wherein the sonotrode and the converter are arranged in mutually adjacent relationship along a longitudinal axis and the ultrasonic vibration unit can be caused to resonate with an ultrasonic vibration in the direction of the longitudinal axis with a wavelength λ/2, wherein there is provided a holder for holding the ultrasonic vibration unit. To provide an ultrasonic welding installation which allows simple and quick highly precise adjustment of the sealing surfaces of the sonotrode relative to the anvil it is proposed according to the invention that the holder has an angle positioning device, wherein the angle positioning device and the ultrasonic vibration unit are of such a configuration that they can be connected together in positively locking relationship so that a rotation of the ultrasonic vibration unit about the longitudinal axis is prevented by the positively locking connection and a relative movement between the ultrasonic vibration unit and the holder in the direction of the longitudinal axis is not prevented.
