20130248107 | Sealing Device and Method for Sealing a Container Bowl with a Heat Sealing Film - A sealing device for sealing container bowls with a heat sealing film has several sealing heads each correlated with one container receptacle. The sealing heads are movable in a sealing stroke direction relative to the container receptacles that are connected fixedly to each other. The sealing heads are forced with pretension into a rest position by spring elements in the sealing stroke direction against a stop, each sealing head having one stop associated therewith. For simultaneous sealing of the heat sealing film onto the several container bowls, a spring support, on which the spring elements are jointly secured, is moved together with the sealing heads so far in the sealing stroke direction relative to the container receptacles that the sealing heads upon impacting on the container receptacles correlated therewith, with interposition of the container bowls and the heat sealing film, are lifted off their stops against the pretension. | 09-26-2013 |
