Patent ID: 8795453

Claim:
A device for processing a packing material by means of ultrasound, comprising at least one sonotrode ( 10 ), at least one anvil ( 12 ), wherein for the purposes of ultrasound sealing of a packing material a gap (s) through which the packing material can be guided is formed between the sonotrode ( 10 ) and anvil ( 12 ), at least one adjusting means ( 50 ) which adjusts the gap (s) between the sonotrode ( 10 ) and anvil ( 12 ), at least one generator ( 70 ) which converts an input voltage into a suitable output voltage which is converted by a converter ( 74 ) into mechanical vibrations in order to generate ultrasound vibrations at the sonotrode ( 10 ), characterized in that a regulator and/or controller ( 78 ) is provided for the regulation and/or control of the gap (s) between the sonotrode ( 10 ) and anvil ( 12 ) as a function of at least one electric variable from the group consisting of the power (P) of the generator ( 70 ), the energy (E) of the generator ( 70 ), and a resistance (R) between the sonotrode ( 10 ) and the anvil ( 12 ).
