Embodiment Construction

[0032] figure 1 Parts of a paper rotary printing press are shown, containing two printing mechanisms and being used for the following purposes:

[0033] - The printed sheet is first provided with a flat or imaged (bildgebend) adhesive mold (Klebstoffmuster) (printing unit as coating unit (Auftragwerk) 1 ).

[0034] - In the continuous printing unit, the printed sheet is guided together with the transfer film 5 under pressure through the transfer nip 6 (coating unit 2 ).

[0035] The coating unit 1 can be a known offset printing unit with a coloring unit 11 , a plate cylinder 12 and a printing cloth cylinder 13 . The printing cloth cylinder 13 cooperates with the impression cylinder 4 .

[0036] The coating means 2 can likewise be formed by an offset printing means. The transfer nip 6 in the coating unit 2 is formed by the pressure roller 3 and the impression cylinder 4 . The pressure roller 3 may correspond to a printing cloth cylinder. The pressure roller 3 can also corr...

Abstract

The film feed in a coating module for transferring imaging layers from a transfer film onto a printing material is to have its applicability extended. To this end, a limited pressing surface is arranged in the coating module for transferring layers from the transfer film (5). Targeted control of the film advancing is therefore possible. Here, the transfer film is preferably guided in a limited width and approximately tangentially past a press roll (3). In order to limit pressing surfaces, format supports (30, 31, 32) for the press fabric (10) are provided.

Description

technical field [0001] The invention relates to a device for transferring an imaging layer from a carrier film to a printing sheet and a method for coating the printing sheet. Background technique [0002] It is known to produce metal layers on printed sheets by means of a film transfer process. A printing material and a printing device using this material are thus described in document EP0569520B1. A machine for processing paper is shown here with a sheet feeder (Anleger) and a support arm (Ausleger), wherein a printing unit and a coating module are arranged between the two units. In at least one of the printing units, the adhesive mold is applied by means of a lithographic process. The adhesive mold is applied in a cold printing process and has a defined imaged volume (Sujet). A film guide is arranged in the coating module with impression cylinders and press rollers next to the printing unit. It is designed such that the film web or the transfer film is guided by the f...
