Claim:
1. Drying drum assembly for a sheet handling apparatus for holding sheets comprising: a rotary drum having an outer peripheral wall provided with openings; a strip with perforations formed therein, which strip spirals circumferentially over an outer surface of the peripheral wall of the drum in a circumferential spiralling direction, such that a screen is formed over the peripheral wall of the drum, wherein the openings of the drum and the perforations of the strip are positioned with respect to one another for being in a fluid connection to one another and to a suction system, which suction system is arranged for controlling a flow of air through the openings of the drum and the perforations of the strip to removably fix the sheets on the screen, wherein the strip is biased by means of a tensioning device, which exerts a tensioning force on the strip substantially parallel to the circumferential spiralling direction of the strip.
