Lateral sealing for a flip-flow screen

摘要

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.

1. A flip-flow screen, comprising:
a screen frame having lateral longitudinal walls that define a screening direction; a plurality of crossmembers mounted to the screen frame and extending transverse to the screening direction, wherein the crossmembers alternate as being either fixedly mounted or movably mounted to the screen frame; a plurality of liner carriers that are attached to the plurality of crossmembers, each liner carrier having lateral edge regions, end regions, and end faces; wherein the lateral edge regions curve upwardly, at least some liner carriers of the fixed crossmembers are fastened at their end regions to the lateral longitudinal walls of the screen frame, and at least some liner carriers of the movable crossmembers are fastened at their end regions to the lateral longitudinal walls of the screen frame; and a screen liner mounted on the liner carriers.
