ABSTRACT:
Cylindrical sieve for paper pulp strainer of the type of thin sheetmetal is formed by juxtaposition of U-shaped sectional elements (2) made from a metal strip. The element (2) has a first flange (3), a bottom (4), followed by a second flange (5) bent over toward the exterior of the U-shaped element on itself so as to define a space (6) in the fold thus formed, intended to receive and hold the first flange (3') of the adjacent element (2'). The base of the U-shaped element is pricked to form depressions or slots.
