Abstract
Tools supporting and heating device for tools like printing plates, used for diecutting and hot pressure transfer of portions of metallic films on a substrate. This device comprises a base plate applied against one of the sides of the honeycomb chase. This base plate is made of a sequence of at least one insulating surface and of at least one conducting surface enabling to feed at least one heating device intended to be inserted inside each one of said apertures in order to heat a printing plate fastened against a second side of the honeycomb chase.
Claims17
A support and heating device for tools for hot embossing or diecutting with hot pressure transfer of metallic film portions onto a substrate, the device comprising:
- at least one platen;
- at least one honeycomb chase having two opposite parallel sides with a plurality of apertures at spaced apart locations in the chase;
- a base plate secured against one of the sides of the honeycomb chase, the base plate comprised of at least one insulating surface alternating with at least one conducting surface;
- a plurality of heating devices, each inserted into one of the apertures in the honeycomb chase, and the heating devices being operable to heat a printing plate that is selectively securable against the second side of the honeycomb chase, the printing plate being positioned for cooperating with the at least one platen for hot embossing or diecutting and hot pressure transferring a metallic film portion onto the substrate.
