ABSTRACT:
The friction feeder for paper sheets is provided with a continuously rotating feed roller (2) arranged under a decollation plane and with an immobile decollating roller (4) arranged above it with parallel axis, forming an adjustable decollating gap. Continuously driven conveyor belts (14-17), whose delivery strands (14'-17') extend on both front sides of the feed roller (2) in the decollation plane are also provided. To achieve accurate starting and stopping of the decollation process, pre-decollating rollers (35, 36), which loosely lie on the delivery strands (14'-17') of the conveyor belts (14-17) in front of the decollating roller (4) in the delivery direction (arrow 7), and the pre-decollating rollers are mounted nonrotatably on a common, freely rotatable shaft (37), whose axis is parallel to the decollating roller (4), and the lowermost paper sheets of a sheet stack (23) located in front of the pre-decollating rollers are in contact with the pre-decollating rollers. These pre-decollating rollers (35, 36) can be lifted off from the delivery strands (14'-17') of the conveyor belts (14-17) by means of a lifting device (44-51) arranged under the decollation plane (1).
