ABSTRACT:
An ultrasonic welding device for mounting wire ends or wire loops on terminal lugs, particularly on terminal lugs or lamellas of drum-shaped commutators for rotating electrical machines, the arrangement comprises a sonotrode, an anvil against which terminal lugs abut during a welding process, and supporting surfaces provided on the anvil and on a free end of each terminal lug for taking up a sonotrode pressure and sonotrode vibrations transverse to a pressure direction. The supporting surfaces abut against one another before a start of a welding process by a relative movement of the anvil and the terminal lugs.
