Claim 0:
1. An ultrasonic welding installation comprising an ultrasonic vibration unit having a sonotrode and a converter,
wherein the sonotrode (1) and the converter (3) are arranged in mutually adjacent relationship along a longitudinal axis having a direction 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 (5) for holding the ultrasonic vibration unit, characterised in that the holder (5) 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 a positively locking relationship so that 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, and
wherein the ultrasonic vibration unit has an outer bead (37) with at least one recess (21), wherein the angle positioning device has at least one projection (27) which corresponds to the at least one recess (21) and which can engage into the at least one recess (21) and thus provide the positive locking connection.
