Abstract
The present invention concerns an apparatus for ultrasonic welding of at least two material webs comprising a processing sonotrode which can be excited with an ultrasonic vibration, a processing counterpart tool and a material web guide which is so designed that the material web can be passed through between the processing sonotrode and the processing counterpart tool, in which there is provided a device for heating at least one material web prior to the welding operation. To provide an ultrasonic welding apparatus which avoids the stated disadvantages and which nonetheless provides a high processing speed it is proposed according to the invention that the device for preheating at least one material web has a preheating sonotrode which can be excited with an ultrasonic vibration.
