Abstract
A mechanism for encoding continuously moving documents. Documents are transported between a plurality of fixed dies and a plurality of electronically controlled hammers. An ink bearing ribbon is interposed between the documents and the fixed dies and is momentarily transported at the same velocity as the documents. As the documents traverse the plurality of fixed dies, the electronically controlled hammers are cycled, in a selected sequence and at selected positions, to provide the desired encoding. In those applications wherein the cycle time of the electronically controlled hammers is too slow to allow identical encoding in adjacent positions, a second plurality of fixed dies and electronically controlled hammers may be located adjacent to the first plurality or interspersed among the first plurality of fixed dies.
