Device for hot-pressure transfer of metallic films onto a substrate of paper or cardboard

A device positioning and securing, tools (10) in the shape of small plates for cutting and hot-pressure transfer of portions of metallic films onto paper or cardboard substrate, on a supporting and heating plate (3), this device comprising first securing means (11-13) for said tools (10) on said supporting and heating plate (3), wherein the heat exchange surface of said supporting and heating plate (3) is continuous, the first securing means (11-13) being arranged so as to permit securing each of these tools (10) in any position within an adjusting range determined on the surface of said supporting and heating plate (3), in order to allow adjusting the position, then the securing said tools (10) on said supporting and heating plate (3) in an adjusted position, and that it comprises positioning means (7-9) for the positioning the supporting and heating plate (3) on a removable frame (1) of a press for hot transfer of portions of metallic films, in which the first securing means include screws (12) with flat heads (12a), the tools (10) comprising, for each of said screws (12), a well of diameter substantially larger than the diameter of the flat head (12a) and height greater than the thickness of the flat head (12a), the well being terminal at its lower end by an annular seat (13) defining an aperture (11), of a diameter substantially larger than said screw's (12) diameter, the spacing between the diameter of said aperture (11) and the diameter of said screw (12) determining the adjusting range, the diameter of the well being larger than the diameter of the head (12a) by at least said adjusting range.
