Selective embossing press with drum stop means

An embossing press comprising a pair of oppositely disposed embossing rolls, each said embossing roll comprising a shaft, a plurality of indicia drums mounted on said shaft with each said drum mounted opposite a corresponding said drum on the other said shaft, means for releasably coupling said indicia drums to said shaft for rotation of said drums with said shaft, said means permitting the uncoupling of said drums and said shaft on the application of a sufficient force, upstanding indicia mounted on and spaced angularly apart on the outer periphery of said drums of one said shaft, and complementary indented indicia mounted on and spaced angularly apart on the outer periphery of said drums of the other said shaft, shaft drive means operatively connected to each said shaft for rotating each said shaft and said drums thereon from an initial rest position through a predetermined angle of rotation so that all of the indicia on each said drum can be moved into an operative position confronting the corresponding indicia on the corresponding drum on the other said shaft, arrestor means for holding each of said drums in position, each said drum having a plurality of grooves formed therein to provide an interengagement location with said arrestor means for each indicia on said drum, said arrestor means being selectively engageable with said grooves for arresting each said drum with a selected indicia thereon in the operative position and confronting the corresponding said indicia on the corresponding said drum on the other said shaft, pressure means for urging the oppositely disposed embossing rolls toward one another under pressure for embossing with said indicia located in the operative positions, severing means operatively connected to said pressure means to permit individual sections of material to be severed from a continuous length of sheet material fed to the press for embossing so that individual embossed elements or plates can be produced after the embossment of the individual sections, said severing means comprising a pair of shearing bars, one of said shearing bars being mounted on one of said shafts and the other said shearing bar being mounted on the other said shaft so that said shearing bars are displaceable between their operative positions wherein they cooperate with one another, when the shaft are rotated forwardly from their initial positions, so that they will not obstruct the embossing operation and are returned to their operative positions upon return of said shaft to the initial rest position, bearings disconnectedly mounted on each said shaft for rotation therewith so that relative rotation between said bearings and said shaft can be accomplished, each said shearing bar is connected to said bearings for mounting said shearing baroon said shaft with which it is associated, and stop means arranged for defining an inoperative position of each said shearing bar.
