Patent ID: 7422045

Claim:
A sealing and cutting unit for applying a plastic foil to a planar substrate material to form laminated material by means of heat and pressure comprising: a sealing unit, a die cutting unit and a drive for moving laminated material from the sealing unit to the die cutting unit, said sealing unit comprising a sealing plate with a heated active surface and a back plate which is movable relative thereto said die cutting unit comprising a die cutter with at least one die cutting knife, and a counter plate for making die cuts at selected locations in the planar substrate material in the region of the applied plastic foil, wherein the sealing plate of the sealing unit has at least one set of raised and depressed regions on a surface facing a portion on the back plate that forms an area of reduced heating of the plastic foil over the depressed regions and the drive for moving the laminated material provides the laminated material to the die cutting unit so the area of reduced heating corresponds to the location of the die cutting knife during cutting, so that cuts are made only in the area of reduced heating.
