Abstract

See full text

The foil embossing device comprises an embossing roller and two counter-rollers, one of the rollers being driven by a drive and the rollers having a configuration where the teeth, rings, or ridges project from the base cylinder, at least the embossing roller having teeth that project from the base cylinder and at least partly also serve for driving the counter-roller. To increase the uniformity of the embossing of the foil, the embossing roller has a diameter that is reduced by 0.02 to 0.20 mm over a certain length that is at least the same as the width of the foil. The length of the reduced diameter is preferably chosen so as to exceed the width of the foil being printed. Due to this depression, such a device allows a perfectly uniform embossing of foils of any kind independently of the design of the embossing rollers.
