Abstract
An embossing module for an automatic embossing machine utilizes a pair of opposed embossing element carrying wheels driven by oscillating bail arms which directly engage the embossing punch and die elements. An electromechanical interrupter mechanically decouples motion of the bail arm from the embossing elements in the event of a failure. The printwheels are driven by separate motors utilizing separate position encoders and common servo command circuits.
