Apparatus for welding and/or welding and cutting of films

摘要

The equipment has a welding tool (13) and opposing tool (11) between which films are passed. The opposing tool has either an elastic material (30) on the front facing the films or has an elastic front face. When the two tools are moved towards each other during the sealing operation the elastic material compresses. An Independent claim is made for a band rolling machine incorporating the claimed sealing and welding unit.
