ABSTRACT:
A sieve bend has been described incorporating a headbox 40, throat mechanism 46, nip flap 90 and sieve surface area 52 supported by frame 96 which may have portions thereof rotated or positioned behind headbox 40 temporarily until its use is desired. The invention overcomes the problem of requiring frequent end for end reversal of the sieve surface area and of debris jamming the throat mechanism. Further, the invention permits in process variation of the sieve surface area 52 in response to downstream conditions.
