The utility model relates to a screen cylinder (1) used for cleaning or sorting a fiber material mixture. The screen cylinder (1) is internally provided with a cylindrical screen surface (8) formed by screen cuts (5), and the screen cuts are disposed between screen wires (2) and the front surfaces (7) of the screen wires (2). At least one front surface (7) of the screen wires (2) on the screen cylinder (1) is provided with profiling portions (14, 15), and the profiling portions (14, 15) are projections (15) and / or depressions (14) formed on the front surfaces (7) of the screen wires (2). When the profiling portions (14, 15) are observed from the direction of the normal (N) of the front surfaces (7) on the screen wires (2), a molding line (16) of the profiling portions (14, 15), which divides the the region of the profiling (14, 15) on the front surfaces (7) of the screen wires (2) and the remaining area on the front surface (7), comprises at least one arc-shaped portion (17a, 17b, 17c, 17d). |
