Problems solved by technology

[0004] Disadvantages of the described treatment methods are that extensive know-how cannot be used flexibly for complex processes and are difficult to handle
In particular, the hitherto known production methods are limited to the processing of printing substrates made of paper or cardboard
Coating of film substrates by the cold film embossing method has hitherto not been disclosed

Embodiment Construction

[0048] Figure 1 shows components of a sheet rotary printing press comprising two printing units and serving the following purposes:

[0049] - A printed sheet is initially provided with a flat or imaged adhesive pattern (printing unit as coating unit 1 ).

[0050] On the subsequent printing unit, the printed sheet is guided under pressure together with a transfer film 5 through a transfer nip 6 (coating unit 2 ).

[0051] The coating unit 1 can be an offset printing unit known per se, having an inking unit 11 , a printing form cylinder 12 and a printing cylinder 13 . The printing cylinder 13 cooperates with a counterpress cylinder 14 .

[0052] The coating unit 2 can likewise be formed by an offset printing unit. The transfer nip 6 in the coating unit 2 is formed by a pressure roller 3 and a counter-press roller 4 . The press roll 3 may correspond to a counter press roll. The pressure roller 3 can also correspond to the printing form cylinder of a painting unit. Inside th...

Abstract

The invention relates to a coating set for transferring an imaging layer or a coating from a transfer film to a printing substrate, which can be flexibly used for producing composite printing material made of the film material. The invention is characterized in that at least one film binding assembly FA is arranged on a printed sheet roller transfer printing machine, thereby generating variable combination when combining with a printing set, a painting set and at least one turn-over device.

Description

technical field [0001] The invention relates to a method and a device according to claim 1 or the preamble of claim 17 for transferring an imaging layer or cover layer from a carrier film to a printing sheet. Background technique [0002] It is known to produce metallic layers on printed sheets by means of a film transfer method. EP 0 569 520 B1 describes a printing material and a printing device using this material. A printing unit and a coating unit are arranged on a sheet processing machine with a sheet feeder and a sheet discharger. An adhesive pattern as a printing subject is applied lithographically on at least one printing unit. On the coating unit behind the printing unit, a paired extrusion cylinder, a pressing roller and a film guiding mechanism are arranged. In this case, a film web is guided from a film storage reel through the transfer nip of the coating unit between the mating squeeze cylinder and the pressure roller, and is rewound on the exit side after le...
