Abstract
Sieve with slots or holes, made from a U-shaped section, constituted by a stack of identical circles, each circle (1, 1') being made from a tapered U-shaped section of which the two ends are welded or mechanically connected to one another, characterized in that this stack of circles (1, 1') is maintained tightly between two rings (2-3, 2-'3') by a plurality of tie rods (4, 4') and in that the lateral walls of the circles in the stack rest on one another without any further fastening together, so that the walls of the sections can undergo elastic deformation under the effects of the tightening.
