Embodiment Construction

[0010] FIG. 1 shows a machine for processing printed sheets, here a printing press, which comprises at least two printing units.

[0011] In a first step, the printed sheet to be coated is coated in the coating device 1 with an adhesive pattern providing a picture. In addition, a printing unit of an offset printing press can be used, which has an inking and dampening unit 11 , a printing plate on a printing plate cylinder 12 , a blanket or rubber cylinder 13 and a counter-pressure cylinder 4 . Coating devices in the form of flexographic printing units or coating units can likewise be used.

[0012] In a second step, the transfer film 5 is passed through the transfer nip 6 together with the printed sheet under pressure. The film transfer module 2 used for this purpose can be a printing unit of a sheetfed offset printing press, a coating module, a base unit or another type of processing station. The transfer nip 6 in the film transfer module 2 consists of a transfer roller 3 a...

Abstract

To transfer a coating in image form from a transfer foil to a print sheet, adhesive is applied in the form of the image to said sheet. In a foil transfer module (2), the carrier foil with the coating in image form is then brought into contact with the print sheet using contact pressure, so that the coating adheres to the adhesive points and an image is produced. To improve the function, simplify the device and increase the flexibility of the method, a transfer cylinder (3) is provided with a covering that has a variable cover thickness (25), in order to adapt the surface speed of the transfer cylinder (3).

Description

technical field [0001] The invention relates to a device for transferring a graphic-providing layer from a carrier film to a printed sheet according to the preamble of claim 1 . Background technique [0002] It is known to produce metal layers on printed sheets by means of film transfer methods. A printing material and a printing device using this material are described, for example, in EP 0 569 520 B1. This patent document shows a machine for processing printed sheets, which has a feeder and a delivery, wherein a printing unit and a film transfer module are arranged between these two units. The adhesive pattern is applied in at least one of the printing units by means of lithographic printing. The adhesive pattern is applied in a cold printing process and has a specific theme providing a picture. In the film transfer module arranged downstream of the printing unit with a pressure cylinder and a transfer cylinder, a film guide is arranged. The film feed is designed such ...
