Abstract

A screening cylinder for screening suspensions of lignocellulosic fiber material. The screening cylinder (10) is formed of rods ( 11), which between themselves form gaps (12) extending along the entire length of the cylinder (10). The rods (11) are held toget her by a number of overall rings (16) arranged on the cylinder. In order to improve the efficiency of the screening cylinder, the upper surface of the rods (11) is provided with at least one depression (15) between edge portions (13, 14) of the rods (11).
