Sieve base with elastic detachable strip sieve elements - has fastening battens connecting longitudinal edges of elements to lightweight support structure

摘要

The sieve base is provided with strip-like rubber elastic sieve elements (2) fastened along their longitudinal edges to the support structure (4) using battens (3) provided with projections (8, 10) designed to snap into openings in the support structure or which can be connected by separate retaining elements. An open sieve surface is obtained and the support structure can be made lighter with greater manufacturing tolerances. If the inherent stability of the sieve elements is not sufficient the elements can be provided with reinforcement rods (6) across the longitudinal extension of the elements (2) and which have at their ends recesses which interact with one arm of an angled section (5) mounted at right angles.
