Abstract
Flip-flow screens having crossbars which extend transversely to the screening direction, carry a screen liner and are mounted alternately fixedly and movably with respect to a screen frame, where the screen liner is mounted on liner carriers which are curved upward in their lateral edge regions. In order to improve lateral sealing, provision is made for all the liner carriers to be fastened, preferably screwed, by their end regions to the screen frame. The lateral edge regions are preferably curved by 80-90°, and the liner carriers of the movable crossmembers may have in their curved portion a cross section which is tapered in relation to the rectilinear portion and/or which may consist of a softer material.
