Abstract
Abstract A coating method in which a coating film is transferred from a film carrying roll leaf, onto the surface of a product. A positioning platform, together with a pressure member which acts against the platform, define a transfer station at which the roll leaf and product are concurrently aligned. A continuously moving and guided thermal belt preheats the foil sufficiently to effect separation of the roll leaf decorative layer from the carrier, and assure its transfer to the product surface.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
121 words
Method for decorating a product surface by transferring a decorative roll leaf thereto from a foil which comprises a carrier, to which the decorative roll leaf has been bonded with a thermally meltable adhesive, which method includes the steps of; contacting at least one of two pressure elements with a thermal belt, the latter defining a closed loop and being sequentially progressed into heat exchange engagement with a heat source and with one of said pressure elements and compressing the foil against said product surface between said two pressure elements, said at least one heated pressure element concurrently heating the foil to a sufficient temperature to melt said adhesive whereby to permit separation of the decorative roll leaf from the carrier.
Claim 2
Dependent Claim
