Abstract
Cylindrical screen, particularly for paper pulp, of the type comprising at least one filtering element (10) positioned between two flanges (1, 2) by means of a number of bars (3). The filtering element is composed by wires (10) placed side by side and held by rings (11). This filtering element is rigid in the axial direction and is placed upstream from the above mentioned bars (3), in relation to the direction of flow of the pulp. The filtering element is held against the bars (3) through the rings (11) that are in contact with the bars without being attached to them, so as to maintain its shape by withstanding the pressure exerted by the pulp.
