Abstract
A screening apparatus comprises an elongated support frame; a mobile, deformable sieve consisting of a sieve mat extending along the length of the support frame and having lateral edges; and a series of alternatingly immobile and mobile sieve mat carriers mounted on the support frame and extending transversely to the length of the support frame, the sieve mat being affixed to the carriers and the mobile carriers being movable with respect to the support frame in the direction of the length of the support frame, the lateral sieve mat edges extending transversely to the carriers and being raised to form rims for the sieve mat.
