A sheet feeder for advancing paper sheets one by one, has at least one traveling feeder belt whose one side is a feed plane and a stationary sheet restraining or retarding element that has a friction surface that faces towards and is spaced from the feed plane. The space between the friction surface and the feed plane forms a feed opening whose gap decreases in the feed direction. The feed belt runs on a belt support that is stationary, flat and rigid and extends along the greater part of the feed opening in the sheet transporting direction. |
