Abstract
An apparatus for joining a bottom foil to a cover foil comprising a heating roller and a sealing roller that cooperates with the heating roller. In the inlet region of the heating roller, there is a preheater for the cover foil. To enable especially good handling of the cover foil, an additional preheater, embodied as a heating wedge, for the cover foil is disposed in the immediate vicinity of the heating roller. Instead of the preheater, the sealing roller may also be embodied as heatable.
