The screen cylinder (1) is composed of three parts (2, 3, 4) arranged one within the other and connected to each other by a shrink fit. A perforated plate part (3) located in the middle having small holes (14) or slots is sandwiched between the inner part (2) and the outer part (4). The outer part and the inner part have large apertures (6, 10) each of which extends over several small holes (14) in circumferential direction of the perforated plate part (3). |
