The invention relates to a flip-flow screen (1) having crossbars (3, 4) which extend transversely to the screening direction (11), carry a screen liner (9) and are mounted alternately fixedly and movably with respect to a screen frame (2), wherein the screen liner (9) is mounted on liner carriers (6) which are curved upward in their lateral edge regions (7). In order to improve lateral sealing, provision is made for all the liner carriers (6) to be fastened, preferably screwed, by their end regions (7') to the screen frame (2). The lateral edge regions (7) are preferably curved by 80-90°. In one embodiment, the liner carriers (6) of the movable crossmembers (4) have in their curved portion a cross section (12) which is tapered in relation to the rectilinear portion and/or consist of a softer material. |
