A paper sheet guiding cylinder for a printing machine is mounted in the machine side frames, is drivingly linked to the printing machine drive, and has an outer casing provided with through holes. Means are provided for blowing air into the paper sheet guiding cylinder and means located inside the paper sheet guiding cylinder deflect the blown air in the direction of the cylinder casing. In order to deflect the blown air, a radial ventilator is rotatively mounted in the paper sheet guiding cylinder (11) and is linked to driving means which are independent from the paper sheet guiding cylinder. Through holes are provided in the side walls (20) of the paper sheet guiding cylinder (11).
