Beschreibung
Zusammenfassung:	A suction roll system (1) with a rotatably mounted cylindrical suction roll (32), a cylinder jacket (34) of which is provided with a plurality of suction holes (36), which can be selectively connected via a control system individually or in groups to a vacuum system (14), is intended to make possible, in a reliable fashion, a particularly short switchover times and also a high flexibility, even when groups of a plurality of suction holes (36) are actuated. To this end, according to the invention, the control system comprises a fixedly mounted hollow cylinder (2) projecting into the suction roll (32) and connected by its interior volume (10) to the vacuum system (14), the cylinder jacket (20) of which is penetrated by a number of control slots (22).
