摘要： A forming roll for a paper-making machine of the two wire type comprises a cylindrical roll body and a multiplicity of generally corrugated-shaped ribs extending generally radially outwardly from and generally longitudinally along the surface of the cylindrical body. All of the ribs are of substantially identical wave shape along their lengths, and the ribs are substantially equally spaced apart circumferentially of the body. The ribs define a multiplicity of zig-zag, regular wave-like cells of uniform size and shape, each of which cells has a dimension longitudinally of the roll that is substantially greater than its dimension circumferentially of the roll. The medial axes of all of the cells at corresponding points circumferentially of the roll intersect cross-sectional planes of the roll at substantially the same angle such that the wave forms of all cells are substantially in phase longitudinally of the roll.

摘要： CELLULOSIC MATERIALA ARE CONTINUOUSLY DIGESTED AND SUBSEQUENTLY WASHED WITH A LIQUID TO PRODUCE A PULP IN A CLOSED, SUBSTANTIALLY STRAIGHT VESSEL HAVING AT LEAST ONE PARTITION STRUCTURE WITHIN IT AND EXTENDING GENERALLY TRANSVERSELY AND SUBSTANTIALLY LONGITUDINALLY OF THE VESSEL TO DIVIDE IT INTO AT LEAST TWO GENERALLY LONGITUDINALLY EXTENDING COMPARTMENTS. STEAM IS INTRODUCED INTO THE UPPER PART OF THE VESSEL FOR DIGESTION OF THE MATERIAL, AND A WASHING LIQUID IS INTRODUCED SEPARATLEY UNDER CONTROLLED CONDITIONS INTO THE RESPECTIVE COMPARTMENTS TO WASH THE MATERIAL. CELLULOSIC MATERIALS WHICH HAVE BEEN PRETREATED WITH CHEMICALS THAT PROMOTE DIGESTION ARE INTRODUCED SEPARATELY INTO EACH COMPARTMENT AND ARE WITHDRAWN SEPARATELY FROM EACH COMPARTMENT AT CONTROLLED RATES.

摘要： A double-felted press for a papermaking machine or the like comprises a pair of press rolls arranged to form a nip and an endless press felt trained around a segment of each of the rolls, the press felts passing through the nip. One of the rolls is a suction roll, and the suction zone is located entirely on the downstream side of the roll, relative to the direction of rotation of the roll, from the nip, is contiguous or in proximate relation to the nip, and is within the segment of the roll over which the felt for that roll is trained. A guide roll for the felt associated with the other press roll (the nonsection-roll is normally positioned such that the felt is separated from the web being pressed before the web reaches the suction zone of the suction roll but is arranged to be moved to a position training that felt around the suction zone of the suction roll so that the two felts turn around the suction zone of the suction roll and ensure that the web runs with the suction-roll felt. Normally, the two felts are trained to run together over the suction zone of the suction roll only upon startup of the machine.
