Benefits of technology
"The invention provides a device that can transfer image elements onto printing material in a reliable, economical, and precise manner. The device can also transfer different types of foils adjacent to each other and improve product security through the use of security elements, such as holograms, applied to the transfer foil. The device can control the advance of the foil to prevent unnecessary transfer and can apply multiple image-forming coatings or metallic layers one after the other within a design. The technical effects of the invention include reliable and efficient image transfer and improved flexibility in applications and design options."
Problems solved by technology
However, a disadvantage with these modules is that they cannot be employed in a flexible manner.

Embodiment Construction
[0014] A sheet-processing machine is shown in FIG. 1. In this case, the sheet-processing machine is a printing press, which is composed of at least two printing units. The two printing units can be used as discussed below to transfer an image-forming layer or coating from a transfer foil to a printing sheet.
[0015] In a first processing step, a printing sheet to be coated is provided with an image-forming adhesive pattern. The adhesive coating is produced in an application unit 1, e.g., a conventional printing unit of an offset printing press. The adhesive coating is produced via varnishing and dampening units 11, a printing plate on a plate cylinder 12, a blanket or rubber cylinder 13, and a counter-pressure or impression cylinder 4. Similarly, application units in the form of flexographic printing units or varnishing units can be used.
[0016] In a second step, a transfer foil 5 is guided in common with a printing sheet through a transfer gap 6, with the transfer foil 5 being press...

Abstract
The present invention can increase the number of instances where foils can be fed into a coating module for transferring imaging layers from a transfer foil onto a material that is to be printed. A transfer foil is provided that carries image elements to the foil-guiding mechanism. The image elements are transferred in the coating module from the transfer foil onto the material that is to be printed. The transfer foil can be guided past a pressure roll in an approximately tangential direction.
Description
FIELD OF THE INVENTION [0001] The invention relates to a method and to devices for transferring image-forming layers from a carrier foil onto a material to be printed. BACKGROUND OF THE INVENTION [0002] It is known to produce metallic foils on material to be printed using a foil transfer method. For example, a printing material and a printing device using foil material are described in EP 0 569 520 B1. In that reference, a sheet-processing machine is disclosed, which has a sheet feeder and a sheet delivery system. Printing units and a coating module are arranged between the sheet feeder and the sheet delivery system. In at least one of the printing units, an adhesive pattern is applied using a flat bed or lithographic printing method. This adhesive pattern is applied using a cold printing method and has a certain image-forming design. In the coating module following the printing unit, a foil guide is provided with a counter-pressure or impression cylinder and a press cylinder. The f...
