Embodiment Construction

[0068] figure 1 A device according to the prior art is shown for transferring a transfer layer from a carrier film to a printing material 10 , the transfer layer and the carrier film together forming the transfer film.

[0069] A transfer film tape 3 is wound on a transfer film stock roll 2 . The transfer film stock roll 2 is provided on a stock shaft 1 which rotates in the direction indicated by the arrow. A drive (not shown here) can be provided for rotating the reserve shaft 1 .

[0070]The reserve shaft 2 is fixedly connected to the reserve shaft 1 , whereby the rotation of the reserve shaft 1 is directly transmitted to the reserve shaft 2 . In this way, the transfer film web 3 is unwound from the supply shaft 1 and transported via deflection rollers 4 to the transfer nip 7 . Several deflection rollers 4 can also be provided in order to achieve a corresponding course of the transfer path of the transfer film web 3 .

[0071] The transfer film web 3 is guided in direct...

Abstract

The device has a foil module with a reserve mandrel for accommodating transfer foil reserve roller. The collection device has collecting shaft (11) for accommodating transfer foil collection roll and for uncoiling a transfer foil web (16,17).The reserve shaft and collecting shaft is formed as friction shaft (13), so that the transfer of the rotation motion of the friction shaft takes place over the transfer foil collection roll (20,21). An independent claim is also included for a method for transferring a transfer layer of a carrier foil.

Description

technical field [0001] The invention relates to a device for transferring a transfer layer from a carrier film to a printing material, the transfer layer and the carrier film together forming a transfer film, the device comprising at least one film module with a storage shaft for receiving At least one transfer film storage roll for the storage and unwinding of at least one transfer film strip. The device shall have at least a transfer film guide for guiding the transfer film web from the storage shaft along the film transport path to the transfer nip, wherein the transfer nip is formed by an impression cylinder and a film for transferring the transfer layer to the substrate Transfer roller composition. For this purpose, the printing material is guided through the transfer nip along the printing material transport path. The device also includes a collecting device for receiving at least one transfer film web guided through the transfer nip. [0002] The invention also relat...
