Zusammenfassung:	The subject of this invention is a transfer suction roll (21) for transferring a material web with a perforated suction roll shell (22) that is pivot-mounted in roller bearings (25) and a suction box (24) mounted inside the transfer suction roll (21). The suction box (24) defines a suction zone (37) on the perforated suction roll shell (22) by means of seals (32). According to the invention, a suction hood (26) is arranged on the outer circumference of the transfer suction roll (21) through which air can be sucked out of the suction box (24) through the perforated suction roll shell (22).
