Embodiment Construction

[0028] figure 1 Shown are parts of a sheet-fed rotary press (Bogenrotationsdruckmaschine), which comprises two printing units and is used for the following purposes:

[0029] - First, the printed paper is provided with a planar or image-imparting adhesive pattern (printing unit as application unit (Auftragwerk) 1 ).

[0030] - In the subsequent printing unit, the printing paper is guided under pressure together with the transfer film 5 through the transfer nip 6, (coating unit 2 ).

[0031] The application unit 1 can be a known offset printing unit with an inking unit 11 , a plate cylinder 12 and a cloth cylinder 13 . The cloth cylinder 13 cooperates with the impression cylinder 4 .

[0032] Likewise, the coating means 2 can be formed by a lithographic means. The transfer nip 6 in the coating unit 2 is formed by the pressure roller 3 and the impression cylinder 4 . The pressing roller 3 can correspond to a printing cloth cylinder. The pressure roller 3 can also correspond...

Abstract

The aim of the invention is to develop the foil guiding process in a coating unit (2) for transferring image-forming layers from a transfer foil to a medium to be printed. To achieve this, the coating unit is equipped with a restricted-area pressing plate for transferring layers from the transfer foil. This allows the targeted control of the foil feed. The transfer foil is preferably guided past a pressing roll (3) approximately tangentially to said roll and with a restricted width. Special delivery devices, which can operate cyclically, are provided for storing and delivering the foil.

Description

technical field [0001] The invention relates to a layer for rendering an image (bildgebend) from a carrier film according to the preamble of claim 1 Device transferred to printed paper (Druckbogen). Background technique [0002] It is known to produce metallic layers on printing paper by means of film transfer methods. Thus, in document EP 0 569 520 B1 a printing material and a printing device using this material are described. A machine for processing paper is shown here with a feeder (Anleger) and a delivery (Ausleger), wherein a printing unit (Druckwerk) and a coating module are arranged between these two units. The adhesive pattern (Klebstoffmuster) is applied in at least one of the printing units by means of a lithographic method. The adhesive pattern is applied (aufbringen) in a cold printing method and has a specific theme (Sujet) to give an image. In the coating module with impression cylinders and press rollers downstream of the printing unit, a film guide is a...
