Abstract

A papermaking assembly has a blade gap former with two endless sieve belts (3, 4) which are both deflected by the circumference (5, 6) of a breast roller (7.1, 8.1). The sieves then form a wedge-like inlet gap (10) into which a fibrous suspension (13) is discharged as a jet (12). The jet impinges (14(3, 14(4) at a number of points on the two sieves (3, 4). The sieves subsequently form a sandwich either side of the fibres and feed through a sequence of forming and dewatering stations. The impingement station (9) is a shoe (9.1) with a coating (28) with a series of strips (29.1-29.6) in-line with the direction of sieve travel (S). The gaps between the strips incorporated water drain holes (30.1-30.5), each in contact with the circulating sieve belt (3) within a housing (32). The housing base panel (33) is in contact with the breast roller.
