  • Patent number: 12115772
    Abstract: The invention relates to 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.
