Problems solved by technology

Without adhering to the substrate, the flakes are attached to the substrate-adhered portion of the decorative segment applied to the substrate and may remain attached thereto in an uncontrolled manner during further processing. on or off, causing interference during processing of the embossed film and / or substrate

Embodiment Construction

[0058] figure 1 and 2 A first exemplary embodiment of an embossing device 1 according to the invention is shown schematically.

[0059] In the illustrated embodiment, the embossing device 1 is configured as a lifting embossing device and is used for a roll-to-roll method, in which the substrate 2 to be embossed and the embossing film 3 are supplied on a storage roll 4 .

[0060] The embossed film 3 comprises a carrier film 31, a release layer 32, a transfer layer 33 and an adhesive layer 34 (see image 3 ). under the Figure 9 The structure of the embossed film 3 is described in more detail in .

[0061] The embossing film 3 and the substrate 2 are fed to an embossing station 5 with a vertically movable embossing mold 6 , wherein the underside of the substrate 2 rests on an embossing support 7 in the embossing station 5 . The embossing film 3 is situated with its adhesive layer on the upper side of the substrate 2 . Alternatively (not shown), the stamping die can also be...

Abstract

The invention relates to a method for transferring a decorative segment (3d) of an embossing film (3) onto a substrate (2) by means of an embossing stamp (6), wherein the embossing film (3) comprisesa carrier film (31) and a transfer layer (33) arranged on the carrier film (31). The method comprises the following steps: a) providing the embossing film (3); b) embossing or pressing at least one compression segment (8v) spaced apart from the edge of the decorative segment (3d) into the transfer layer (33); c) embossing the decorative segment (3d) onto the substrate (2); d) removing the remaining embossing film (3r) from the substrate (2), which has been embossed with the decorative segment (3d). The invention further relates to a device for performing the method.

Description

technical field [0001] The invention relates to a method and a device for transferring a decorative segment of an embossed film onto a substrate. Background technique [0002] When applying embossed films (which contain in particular strongly crosslinked paint systems, for example UV crosslinked paint systems and / or paint systems with high layer thicknesses in the paint stack, i.e. the transferred layer thickness of the carrierless film is greater than 5 microns), it is only very difficult to produce clean separation edges during embossing. Furthermore, in these cases the detachment of the membrane complex does not take place at the edge of the application tool, but at an indeterminate position. Through intensive crosslinking, relatively long or very long polymer chains are formed in the lacquer, thereby correspondingly influencing the physical properties of the lacquer. Depending on the hardness of strongly crosslinked lacquers, for example relatively hard and brittle var...
