A document-handling machine feeds currency by means of a pair of separately driven, counter-rotating rolls, as shown in Fig. 1. It is seen that the sections of feed roll 1, and restraint roll 2, alternate rather than directly oppose each other, and interleave by a nominal .010". The two rolls are of different materials with feed roll 1 having a higher coefficient of friction than restraint roll 2. It is apparent that when a group of documents 3 (currency) is presented to the rolls, as shown, the documents will be successively peeled off the top of the (Image Omitted) stack and passed between the rolls. This system, however, is adversely affected by temperature, wear, condition of the notes (old/new), type of notes (US/non US), etc.
