A sheet conveyance system has at least one driven conveying shaft, with a variable spacing of the driven conveying shaft from the sheet stack. The driven conveying shaft includes at least one sheet conveyor that acts on the sheet to be conveyed with a friction coating. A toothed wheel is fixedly disposed on the conveying shaft, whereby this toothed wheel is enclosed by an outer ring that supports the friction coating and has an inner toothing constantly meshes with the outer toothing. The partial circle diameter of the toothed wheel is smaller than the inner toothing. A transferred force acts on the outer ring such that it is placed with a contact force onto the sheet. A spacer maintains a fixed spacing between the axis of rotation of the toothed wheel and the axis of rotation of the outer ring.
