Abstract

1,119,561. Headboxes for paper machines. BLACK CLAWSON CO. 22 June, 1965 [22 June, 1964], No. 26448/65. Heading D2A. [Also in Division F21 In a headbox, means containing a supply of stock is connected to a slice assembly, having a slice outlet through which the stock is discharged on to a forming member, by a plurality of tubular passageways. These passageways are substantially parallel and closely set over at least portions of their lengths connected to the slice assembly, and all terminate in a plane substantially at right angles to the axes of these portions. The slice assembly includes a pair of slice lips converging away from the adjacent ends of the passageways towards the slice outlet, which is in the form of a slot, to define a space of substantially triangular section. As shown, a headbox comprises a supply manifold 1, a slice assembly 2 and a bank of tubes 3. The manifold tapers from its inlet end 9 to its outlet end 10 which may have a valve (not shown) to vary the total flow through the tubes independently of the total flow into the manifold. The inlets of the tubes are arranged in three staggered pairs of rows, which converge into three closely spaced rows, terminating at the rear wall of the slice assembly. The upper lip 33 of the slice assembly is adjustable by screw-threaded rods 29. In modifications (not shown): the rows of tubes are staggered at the slice end (Fig. 5); the tubes are square (Fig. 6), polygonal (Fig. 7) or twisted (Fig. 15); square or vane-shaped rods are mounted in the manifold to create turbulence to prevent the deposit of fibres at the entries to the tubes (Figs. 8-11); the plate bearing the inlet ends of the tubes has a hemicylindrical surface and a clearing device comprising a spider at each end spanning a ring member and helical rods running between the rings is mounted close to the plate and rotated for the same purpose (Figs. 12-14).
