Abstract: A method and an apparatus for cold-stamping onto a three dimensional object. In a first step, an adhesive is applied to the object at a first workstation. In a second step, a transfer film is pressed onto the object by a pressing device at a second workstation. At the same time, the adhesive is cured at the second workstation. As a result, the decorative material of the transfer film adheres to the object at the positions on the object which are provided with adhesive. If, following this, the transfer film is removed from the three-dimensional object after being pressed on, the decorative material remains on the object at the desired positions. At the positions at which in the first step no adhesive has been applied to the object, the decorative material does not adhere to the object but rather remains on the carrier film of the transfer film.

Abstract: A forming tool is used, which has a tool trough arranged in a stationary manner and a pressure bell, which can be lowered onto and lifted away from the tool trough. An arrangement is created in which a single- or multi-layer, initially flat, flexible laminate separates the trough interior from the pressure-bell interior in a pressure tight manner. A table, on which the 3-D substrate to be coated is located, assumes a lowered position within the trough interior; there is a considerable, free intermediate space (between the laminate and the 3-D substrate. A radiant-heater assembly is inserted into said intermediate space. The radiant-heater assembly has a carrier, on the top side of which radiant heaters that can be activated are attached and on the bottom side of which radiant heaters that can be activated are attached.
