Abstract
The operation of sticking stamps from a foil in strip form at predetermined locations on a substrate which has motifs printed thereon and which is pulled through at least one sticking station at a predetermined forward feed speed is effected by means of pressing portions, which are raised radially above a pressing cylinder, in the sticking station. The pressing portions have curved pressing surfaces which are parts of a larger cylindrical surface which is concentric with respect to the pressing cylinder and which during each sticking phase roll against a backing cylinder and transfer the stamps onto the substrate. The strip speed of the foil may also be lower than the forward feed speed. The foil used may be a hot embossing foil with a layer of adhesive or an embossing foil without a layer of adhesive, while the apparatus, for sticking the embossing foil onto the substrate has an applicator mechanism for adhesive upstream of the sticking station and an irradiation station for the activation of adhesive layers.
