1. A document transfer mechanism for transporting a document along a document transfer path, comprising:
- belt means passing over first and second wheel means mounted adjacent to said document transfer path for aligning a segment of said belt means with the document transfer path;
at least one spur means projecting from said belt means for engaging the trailing edge of a document positioned on the document transfer path between the first and second wheel means;
drive means for moving said drive belt means and pushing a document from the first wheel means to the second wheel means; and
accelerator means driven in synchronism with said drive means for engaging the leading edge of a document approaching the second wheel means and increasing the transport speed of the document relative to said belt means, thereby disengaging said spur means from the trailing edge of said document means prior to said spur means passing over said second wheel means.

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.
