A method and a device for affixing a film (7) of a predetermined length to a surface (5) are described. The film (7) is wound on a roller (3) having a circumference which is larger than or equal to the length of the film (7). Then the roller (3) is rotated relative to the surface (5), whereby the film (7) is transferred from the roller (3) to the surface (5).
A method of providing a film (7) of a given length on a surface (5), comprising:
A device for providing a film (7) of a given length on a surface (5), characterized in that the device is provided with a roller (3) having a circumference which is larger than or equal to the length of the film (7) to be provided, means for winding a film (7) around the roller (3), means for displacing the roller, and means for unwinding the film (7) relative to the surface (5).

Corresponding components in the Figures are denoted by the same reference numerals.
FIG. 1 shows a device 1 according to the invention, which is provided with a roller 3 which is rotatable around a centerline 2 in the direction indicated by arrow P1. Roller 3 has a plurality of suction nozzles 4 which are connected to a vacuum pump (not shown). The device 1 is further provided with a transport mechanism for translating an object 6 having a surface 5 in the direction indicated by arrow P2. The object 6 is, for example, a display screen whose surface 5 constituting the display screen is to be provided with a film 7. The film 7 is, for example, a PSA (pressure-sensitive adhesive), a hard coat connected thereto and a PET layer connected thereto, having a total thickness of, for example, 0.2 mm.
The device 1 operates as follows.
