  • Patent number: 6016745
    Abstract: An improvement is provided for an embossing machine of the type having a rotating dual die character wheel assembly. The die character wheels are mounted independently from their outer surfaces within the embossing machine so that a completely unobstructed region exists between the character wheels. This allows a workpiece to be marked to pass unimpeded through the region so that the entire workpiece is capable of being marked. Pinion gears are provided at the outer periphery of the character wheels which engage ring gears mounted on the character wheels whereby the character wheels are rotated simultaneously.
