<p>Flip-flop screening jig comprising a first moved system, having a first transverse member (2), and a second moved system, having a second transverse member (4), wherein the first and second moved systems are arranged movably in relation to each other and at least one screening mat (5) is provided, fastened both to an assigned first transverse member and to an assigned second transverse member, in order to achieve alternating compressing and stretching of the screen mats (5). In order to ensure the durability of the fine screen mats in spite of a whiplash effect, it is provided that the screen mat (5) is formed as a fine screen mat produced from plastic woven fabric and is connected to a first transverse member (2) and/or a second transverse member (4) in each case by means of at least one joining element (6, 7, 8), which has a greater elongation at break than the fine screen mat (5) produced from plastic woven fabric.</p> |
