Abstract

The present invention relates to a screen cylinder (1) for dewatering pulp and to a method for producing the screen cylinder, comprising a screen plate (20) intended to surround a rotating screw which presses liquid through the said screen plate (20), the screen plate being surrounded by support rings (30) joined to support elements (40) running parallel in the axial direction of the screen cylinder, the said support rings (30) being held apart by means of spacer devices (50). The invention means that it is possible to use a thin screen plate (20) with a thickness of 1 - 6 mm, preferably 2 - 4 mm.
