Abstract
A singulator of the friction belt type capable of synchronous or asynchronous modes of operation is described. The singulator includes a buffer assembly for accepting a shingled stream of documents, a feeder pinch belt for extracting the first document from the buffer and a scanner for scanning the document as it passes through the feeder into an accelerator which is also a pinch belt. The accelerator accelerates the document to a constant speed leaving the singulator. A control means is provided which operates coupled to the feeder drive and the scanner so that the next upstream document is extracted a predetermine time after the first document leaves the accelerator.
