Apparatus and method for vibration welding

摘要

The present invention relates to a method for vibration welding. The vibration welding is performed with a plurality of mechanically decoupled oscillating heads, each of which is connected with a frequency converter. An electrical circuit connects the frequency converters such that one of the frequency converters can be operated as the master and the other frequency converters as slaves. With the help of the controlling effect of the master, both a synchronous and a targeted asynchronous operation of the plurality of oscillating heads can be realized.
