ABSTRACT:
A sealing unit (8) for applying a plastic foil (7) to a planar substrate material (1) by means of heat and pressure using a sealing plate (11) with a heated active surface and a back plate (9) which is movable relative thereto. In accordance with the invention, sealed material from the sealing unit is provided to a die cutting unit (16) and preferably the sealing unit (8) is linked to the die cutting unit (16). The die cutting unit is provided with at least one die cutting knife (15) and a counter plate (21) for subsequently making die cuts (6) at selected locations in the planar substrate material (1) in the region of the applied plastic film (7). The sealing plate (11) of the sealing unit (8) has at least one set of raised (14) and depressed (13) regions on its active surface facing the back plate (9) and the location of the depressed regions (13) in the sealing plate (11) corresponds to the location of the die cutting knife (15), so that a cut (6) is made at the selected positions in the substrate material (1) where, because of the depressed regions (13) of the sealing plate (11), there is reduced and insignificant heating of the substrate material (1) and its laminations.
