Abstract

A device for the temporary guidance of successively transported sheets along a guiding surface defined by opposite side edges of a sheet, includes a sheet guiding element revolving in a given direction during operation. The guiding element has a groove oriented at least substantially in the given direction and the guiding element has at least one suction opening formed therein. The at least one suction opening has an aperture cross section in the groove to be temporarily covered by a sheet, and the at least one suction opening is subjected to a periodic underpressure exerting a suction effect on a sheet. Such a device exhibits good guiding characteristics at high sheet speeds.
