Paper machine twin-wire former and dewatering device therein

摘要

Object: To prevent lowering of yield of fibers of stock which is pinched by two wires and being transferred, by use of dewatering blades disposed on each of the wires. Dissolving means: A blade set is disposed respectively on two wires 1, 2 forming loops to pinch stock 7 and running therealong and the blades of one blade set are dewatering limiting blades 20, each having a plane portion 20a to support the wires 1, 2 and an inclined face 20b disposed on the wire entering side of said plane portion 20a and forming a space of wedge-shape facing to the wire face and enlarging toward the upstream side in the wire running direction; the blades of the other blade set are dewatering blades 21, each having a plane portion 21a to support the wires 1, 2 and an edge 21b to scrape water toward the upstream side of said plane portion 21a; and said plane portion 21a having said edge 21b is disposed opposingly to said space of wedge-shape. <IMAGE>
