Abstract
Apparatus for screening a papermaking pulp or stock suspension through a stationary cylindrical screen includes a rotating hydrofoil member which has a curved outer or camber surface portion mounted for rotation with the camber surface in a close but spaced proximity to the inside surface of the screen, in which a discrete part or segment of the body of the member is movable with respect to the body and defines a portion of the curved camber surface, so that the effective spacing between the curved surface and the adjacent inside surface of the screen may be adjusted. The hydrofoil is fabricated from sheet metal and forms an outwardly opening spanwise slot, and a sheet metal fabricated segment is received within the slot and forms a substantial continuation of the outer surface, and is adjustable by a threaded fastener which is accessible through a slot formed in the face surface of the hydrofoil.
