摘要： A sheet handling apparatus comprising a rotary drum having an outer peripheral wall with perforations, and a number of separate chambers, a suction system for controlling a flow of air through the perforations, thereby to attract sheets to the peripheral wall of the drum, and a stationary shutter member for blocking the flow of air through the perforations when they pass through a predetermined angular range. The number of separate chambers extend in axial direction and are distributed over the periphery of the drum. A disk-shaped manifold at the first axial end of the drum is co-rotatably with the drum. The manifold forms a number of radial channels each connected to one of said chambers and having an opening at a radially inward end of each channel. The stationary shutter member is arranged for blocking an opening of a channel to block air flow from a radially inward end of a channel.
