Abstract
The invention relates to a laminating foil having an initial roughness on at least one side, which makes the laminating foil matte, wherein the laminating foil has a marking configured as a surface pattern with surface portions on the matte side or at least on one of the matte sides, wherein the roughness of the surface portions is different from the initial roughness. The invention furthermore relates to a laminating foil set comprising the laminating foils, a method for hot laminating sheet material using such laminating foils, a laminating unit for using the laminating foil, and eventually a laminating system including the laminating unit and the laminating foils.

(canceled)
The method according to claim 25, wherein the roughness of the surface portions is less than the initial roughness, but not less than the end roughness, wherein the surface portions are configured as straight and parallel line portions extending with an offset from one another, wherein the line portions are configured, so that they extend transversally to the pass-through movement through the laminating unit, wherein the offset and/or the width of the line portions is configured the greater, the thicker or the thinner the laminating foil is.
The method according to claim 25, wherein a laminating foil is used, which is made of a pair of foil sheets, between which the sheet material is inserted.
The method according to claim 25, wherein the marking is read out through an optical sensor, in particular a laser sensor.
The method according to claim 25, wherein the height of a laminating gap in the laminating unit is also adjusted through the signal.
A laminating foil for performing the method according to claim 25, wherein the laminating foil has an initial roughness at least on one side, which makes the laminating foil matte, wherein the laminating foil has a marking configured as a surface pattern with surface portions on the matte side or at least on one of the matte sides, wherein the roughness of the surface portions is different from the initial roughness.
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 can be laminated under the impact of 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, and wherein the temperature and/or the pass-through velocity is adjustable, wherein the laminating unit comprises a sensor, which is configured for reading out a marking configured as a surface pattern on the laminating foil, which surface pattern comprises surface portions, whose roughness differs from an initial roughness at least on one side of the laminating foil, wherein the sensor generates a signal for a display apparatus and/or for a control apparatus as a function of the read out marking, which control apparatus is connected to the laminating apparatus and/or the transport apparatus and configured, so that the control apparatus adjusts the temperature of the laminating apparatus and/or the pass-through velocity of the transport apparatus as a function of the read out marking.
A method for hot laminating sheet material and laminating foil through at least one laminating unit configured as a piece of office equipment, the method comprising the following steps:
- joining sheet material and laminating foil;
- inserting a combination formed thereby into the laminating unit;
- hot sealing the combination together under the influence of pressure and increased temperature and through adaptation of temperature and/or pass-through velocity to a thickness and/or a material of the laminating foil,
- wherein laminating foil is used, whose initial roughness at least on one side is greater than an end roughness after laminating,
- wherein the laminating foil is provided on the at least one side with a marking in the form of a surface pattern, which comprises surface portions, whose roughness differs from the initial roughness,
- wherein the marking is configured to be read out by a sensor of the laminating unit,
- wherein the laminating foil with its marking is run past the sensor,
- wherein the sensor reads out the marking and generates a signal which is characteristic for the marking, and a temperature and/or a pass-through velocity is adjusted as a function of the signal.
