The invention relates to a sifting device, such as a perforated basket, a perforated cylinder or the like, in which slits or gaps are formed between sieve bars (6). The base of the sieve bars is received in receiving recesses (8) adapted to the dimensions of the base of the bars, in a carrier element (3). Said carrier element can also be a reinforcing or strengthening elemen t, and the sieve bars (6) are permanently fixed to the respective carrier el ement (3). At least one pocket (10, 11) that can be filled with a filler mat erial is provided between each carrier element (3) and each associated sieve bar (6), at least on the edge region (7) of the respective receiving recess (8). In the sifting device according to the invention, said pocket interrup ts the contact surface between the outer contour of the sieve bar (6) and th e inner contour of the associated receiving recess in the carrier element (3 ), such that a pre-determined intermediate space is formed in a targeted man ner in the form of a pocket (10; 11), at least on the edge region (7). Said pocket is then filled with a homogeneous or composite filler material used a s a fixing means, a constituent of said filler material being, for example, an adhesive. In this way, a permanent solid connection can be created betwee n sieve bars (6) and carrier elements (3).
