Patent ID: 8783324

Claim:
A device for processing a packing material by use of ultrasound, comprising: at least one bearing shield; at least one sonotrode which is rotatably mounted in the at least one bearing shield and defines a longitudinal axis about which the at least one sonotrode rotates; at least one anvil which interacts with the sonotrode in order to process the packing material; at least one further bearing shield for rotatably mounting the anvil; and at least one coupler configured to mechanically couple the at least one bearing shield and the at least one further bearing shield, wherein the coupler is designed so as to permit a relative movement between the at least one bearing shield and the at least one further bearing shield, and wherein the coupler is connected to the at least one bearing shield and the at least one further bearing shield in such a way the at least one bearing shield and the at least one further bearing shield are rotatable relative to one another about an axis that is generally parallel to the longitudinal axis of the at least one sonotrode.
