The invention relates to a sieve for a paper pulp scrubber or similar equipment, and to a method for fabricating such a sieve. The sieve is produced by mechanical interfit of bars with support members, the bars carrying notches, the lips of which engage at least one V-shaped lateral groove formed in each support member, while the support members present, on their face receiving the bars, a first set of notches for positioning the bars. The cross-section of the support members at the level of the first notches has the same configuration and dimensions as the cross-section of the second notches and the cross-section of bars at the level of notches has the same configuration as the cross-section of notches formed in the support members. Assembling is made by bending a bar by an angle of about 20-25 DEG for widening a second notch and inserting a support member therein. The bar is then straightened back, so that the support member will be firmly clamped in the notch. |
