To produce a sieve, sieve strips (2) are produced with openings (7) for sorting the fibre suspension. The long sides (4) with identical shape surfaces (5) along their length extension. At least two bar carriers have open recesses (6) at one side, at a given gap (a). Profile rods (1) are made, where the profile at the foot has a joint contour (10) to fit into the carrier recess (6). The sides are profiled with grooves (8) or projections (9), to fit into the shape surfaces (5) at the strips (2). The profile rods (1) are positioned in the carrier (3) recesses (6), parallel to each other, by laying or sliding into place, with the sieve strips (2) parallel to each other between them. The carriers (3) are manipulated into their final shape that, at the same time, distorts the mountings for the profile rods (1) and clamps them in place. Also claimed is a sieve where the carrier (3) is bent into a closed ring, with durably bonded butting ends, to give a cylindrical sieve body, or it is bent into an arc to give a sieve on a circle segment, or the carriers are flat to give a flat sieve body. |
