Abstract:
A device for embossing a foil comprising:a pair of rollers each having a surface provided with a set of teeth;each of the pair of rollers being moveable relative to the other so as to press against each other, whereby the set of teeth of each roller are configured to mutually engage each other via a film to be embossed that is disposed between the rollers;one of said rollers being fixedly supported and driven, the other of said rollers being freely rotatable and capable of being driven by engagement with the fixedly supported roller;wherein the freely rotatable roller is moveable both radially and circumferentially relative to the fixedly supported roller so that upon engagement of the rollers, the rollers self-adjust to a stable mutual position in which teeth of one of the rollers are each symmetrically enclosed between four teeth of the other roller.
