Detection of paper jams in paper or copy folding devices where there is a sensor pair for detection of a paper copy on a conveyor belt and the sensors only send a count impulse to a counter when both sensor receivers detect a copy

摘要

Procedure uses sensors (6, 7) for monitoring a conveyor belt that capture a sequence of folded copies along the transport path. The sensors include a transmitter and a receiver part. Only when both receiver parts detect a copy is a counter impulse (15) generated and sent to a paper blockage detector (12). An Independent claim is made for a device for detecting paper jams.
