Flexible sieve elements are fastened to the grate bars and extend across the gaps between the grate bars. The flexible sieve elements are moved or tensioned and relaxed by the movable grate bars. The lateral seal is formed of flexible material and is connected to the sieve elements and to the side walls. The lateral seal includes sealing leaves which overlap one another in an imbricated manner. Each sealing leaf extends in the sieving direction between two adjacent stationary grate bars.
