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.degree. 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.
A sieve for scrubbers, comprising
A method of manufacturing a sieve for scrubbers, said sieve having a plurality of support members with a lateral groove and a plurality of elongated bars, each said elongated bar having a first set of dovetail notches with a base being wider than an opening and at least one side positioned at an acute angle .alpha. to the base, each said groove being adapted for close engagement with said first set of dovetail notches,
