Patent ID: 8365789

Claim:
A laminating unit for hot laminating sheet material and laminating foil, comprising: a housing, through which a pass-through channel extends, starting at a feed opening for passing through a combination of sheet material and laminating foil, and in which a laminating apparatus is disposed, which is associated with the pass-through channel and in which the combination is laminated through contact pressure and increased temperature, wherein a transport apparatus is disposed in the housing for transporting the combination in the pass-through channel with a particular pass-through velocity, wherein the temperature or the pass-through velocity is adjustable, wherein the laminating unit includes a sensor, which reads out a marking encoding at least one physical property of the laminating foil and configured as a surface pattern on a surface of the laminating foil, wherein the contact pressure is applied by the laminating apparatus to the surface of the laminating foil, wherein the surface pattern includes surface portions, whose roughness differs from an initial roughness at least on one side of the laminating foil before laminating, wherein the sensor generates a signal for a display apparatus or for a control apparatus as a function of the read out marking, and wherein the control apparatus is connected to the laminating apparatus or the transport apparatus and configured, so that the control apparatus adjusts the temperature of the laminating apparatus or the pass-through velocity of the transport apparatus as a function of the read out marking.
