ABSTRACT:
For embossing a metal foil the same is passed between two similarly toothed rollers positioned so that the teeth of each roller engages the teeth of the other. A high-quality embossing is obtained which may be kept practically constant over long periods of operation. The rollers are mutually synchronized such that only one of these rollers need be coupled with a driving mechanism. The other roller is free and may easily be removed, replaced or adjusted in order to vary the force by which it is pressed against the foil and the driven roller respectively.
