The guiding element has agroove oriented at least substantially in the given direction and the guiding element hasat least one suction opening formed therein. The at least one suction opening has anaperture cross section in the groove to be temporarily covered by a sheet, and the atleast one suction opening is subjected to a periodic underpressure exerting a suctioneffect on a sheet. Such a device exhibits good guiding characteristics at high sheet speeds.
