摘要

A flat sieve for farinaceous or granular products in different fractions or qualities, with an oscillatory drive and at least one sieve stack, has the upper termination of the sieve stack formed by an inlet frame which has at least one front tensioning unit with at least one guide element, by means of which a tensioning element (8) is vertically movable. The guide element is a cam plate in which a roller is guided which corresponds to the tensioning element and the movement of which corresponds with the vertical movement of the tensioning element.
