ABSTRACT:
In an embossing press, a pair of rolls are arranged to be moved toward and away from one another to effect the embossing operation. Each embossing roll includes a number of drums with replaceable indicia plugs on their circumferential peripheries. The drums are detachably coupled to a shaft so that the drums can rotate with the shaft or can be uncoupled while the shaft continues to rotate. A drive system is connected to each of the shafts for rotating them through a predetermined angle of rotation. An arrestor set-up is associated with the drums for uncoupling each drum from its shaft so that a particular indicia plug is located in the operative position of the embossing rolls. A feeder mechanism directs a continuous length of sheet material into the operating position of the rolls and shearing blades, movably connected to the shafts, are arranged to cut the sheet materials into individual sections.
