Abstract
The invention relates to a method for operating an ultrasonic welding machine. During a welding process, a flat material is continuously moved through a gap formed between a sonotrode (), which is vibrated at an ultrasonic frequency with a welding amplitude, and an anvil () at a welding speed while a welding force is exerted onto the flat material by the anvil () and/or the sonotrode (). The invention is characterised in that during a welding phase, the ACTUAL temperature of the flat material is measured after the flat material has passed through the gap, the ACTUAL temperature is compared with a predetermined TARGET temperature, and the welding amplitude is varied on the basis of the comparison result.
