ABSTRACT:
A device for satinizing and simultaneously embossing flat materials that includes at least two embossing rolls. One roll is connected to a driving system. The rolls are adapted to be driven individually or in common and are adapted to be resiliently applied against each other. Pyramidal or conical teeth of the rolls have flattened tips. The teeth of at least one roll are shaped so as to produce embossed signs in corresponding locations of the passing flat material so that the appearance of the embossed signs changes according to at least one of a viewing angle of the observer, a kind, and the position of the lighting source.
