ABSTRACT:
An apparatus for embossing an imprint in a workpiece has a rigid frame having a front end to one side of the workpiece to be embossed and a rear end to the other side thereof. At least the front end of the frame can move relative to the workpiece in a longitudinal direction across the workpiece and between the front and rear frame ends. An anvil on the front frame end is engageable with the one side of the workpiece. A tool support on the rear end of the frame can move longitudinally relative to same and to the workpiece. A tool wheel rotatable on the tool support about a transverse tool axis generally perpendicular to the longitudinal direction has a periphery carrying a plurality of different embossing tools spaced angularly about the tool axis. This wheel is angularly displaceable through a plurality of respective positions in each of which a respective one of the tools longitudinally forwardly confronts the other side of the workpiece in line longitudinally with the anvil. An actuator is engaged backward against the rear end of the frame and is forwardly engageable with the tool wheel at a location thereon diametrally relative to the tool axis opposite the tool confronting the workpiece. Thus the actuator can expand longitudinally and pull the anvil back into engagement with the one side of the workpiece while pushing the wheel into engagement with the other side of the workpiece.
