ABSTRACT:
A device for guiding a sheet at the exit side of a transport nip formed by a pair of rollers is provided with a movable guide member having a thin end. When the device is in a position of rest, the guide member occupies a position such that the thin end is situated close to but not touching the transport nip. The leading edge of a sheet fed through the transport nip is intercepted by the thin end of the guide member, by means of an operative electrostatic force, whereafter the sheet pushes the guide member ahead of itself and is thereby separated from the nip-forming surfaces of the pair of rollers.
