EMBOSSER HAVING COOPERATING ENDLESS INDICIA CARRIERS DISPLACEABLE RELATIVE TO ONE ANOTHER

摘要

Method and apparatus for the multiple, simultaneous embossment of flexible materials using complementary, character-forming inner and outer bands for each character to be embossed. There is one pair of bands per stage, including an outer, control band and a relatively flexible inner, follower band. Within each stage, the bands are brought into registration with each other in advance of an embossing position but are permitted to move in unregistered contact towards the registration position as the bands are advanced. Beyond the registration position, the bands are separated to accomodate the material to be embossed. In one embodiment, the bands are formed by blocks with respective raised and recessed characters for the inner and outer bands. The blocks are linked together and are hinged in the case of the inner bands.
