• at least two tools for processing of packaging sleeves, and
• at least one parallel spring on which at least one of the tools is movably supported transversely relative to a transport direction of the packaging sleeves, the at least one parallel spring comprising at least two leaf springs which are arranged parallel with each other,
• wherein each tool has an operating region,
• wherein the tools are supported in such a manner that there is produced between the operating regions a gap whose longitudinal direction corresponds to the transport direction of the packaging sleeves, and
• wherein the tools are supported in such a manner that the size of the gap can be changed,
• wherein one of the tools is a sonotrode,
• wherein one of the tools is an anvil, and
• wherein the sonotrode and the anvil have rotation axes which are arranged parallel with each other,
