Abstract
A suction wheel attracts sheets by suction and transports them. The suction wheel contains a suction wheel body rotatable about an axis of rotation and provided with a plurality of suction openings formed in the circumferential surface of the suction wheel body. Accordingly, the suction wheel body is of a non-circular shape. In particular, the suction wheel includes an attraction area for attracting a sheet, a retaining area for retaining and conveying a sheet, and a release area for releasing a sheet. A sheet feeder ideally incorporates such a suction wheel.
