摘要： In a paper machine a paper web is conducted by a continuous felt or the like into the press nip between two rolls. One roll is a suction roll and the other roll is a pressure roll having a single pressure opening located opposite to the suction opening of the suction roll such that it does not encompass the nip between the two rolls. From the pressure opening of the pressure roll a gas, preferably heated, is conducted into the space between the rolls most appropriately before the press nip. A blocking member such as a beam with a triangular cross section may be positioned on the incoming side of the rolls to form a confined space between it and the rolls to prevent escape of the warmed, pressurized gas.

摘要： A drying cylinder in which the inside of the mantle or at least its end portions have circumferential grooves for collecting condensate. The inlet of a condensate drain pipe is placed in each groove and the pipes have been joined to a common condensate collecting pipe having adjustment means for regulating the amount of condensate from the drain pipes. The condensate collecting pipe is further connected to a condensate draining system of the cylinder.

摘要： A compound paper machine system for producing multi-layer paper webs which includes several web forming units and a common endless lower wire or felt therebeneath on which the individual webs are deposited. Each web forming unit may comprise a forming cylinder on which slurry is deposited from a headbox and a separate endless wire or felt which laps part of the upper surface of each cylinder and which is guided so as to deposit the individually formed webs onto the common endless lower wire or felt. Optionally the separate lapping wires or felts for each unit can be a single porous belt.

摘要： The paper machine comprises a horizontal cylinder, a slurry feed box opening onto the top side of the cylinder and the upper rim of the feed slice of which has been continued in order to form a roof-like upper lip between the feed slice and a feed roll placed on the cylinder at an approximate distance from the feed box in the direction of slurry flow, an endless felt or wire running from the feed roll along the cylinder towards the lower part of the same, an appropriate number of guiding and tension rolls for conducting said felt or wire back to the feed roll, a suction box or suction roll placed on the side of the feed roll opposite to that facing the cylinder and at the point where the slurry web and felt or wire depart from the cylinder surface, and possibly a compressed air box or equivalent placed above the felt or wire and after the feed roll, as seen in the direction of travel of the wire, approximately coincident with the gap remaining between the roof-like upper lip of the feed box and the wire. The horizontal cylinder is a suction cylinder which has therein a suction zone extending substantially from and including the upper roof-like lip continuously to the suction box or suction roll. The upper roof-like lip and suction cylinder form a first drying area for the slurry to form a partially dewatered web while the belt thereafter contacts the web against the surface of the suction cylinder over a major portion of the descending surface of the suction cylinder to form a second drying area in which suction and centrifugal force act upon the web to remove additional water.

摘要： AN APARATUS FOR FEEDING PAPER STOCK TO A PAPER MACHINE IN WHICH EVEN DISTRIBUTION OF THE PULP STOCK FREE FROM FIBER ACCUMULATIONS IS OBTAINED ACROSS THE ENTIRE WIDTH OF THE PAPER MACHINE. THE STOCK FLOWS FROM DISTRIBUTION TUBES INTO A CHAMBER THROUGH A PLURALITY OF TRANSVERSE INLET ROWS AND IMPINGES ON THE OPPOSITE WALL OF THE CHAMBER. THE INLET WALL IS PROVIDED WITH HUMPS WHICH EXTEND ACRODD THE CHAMBER, BOTH PARALLEL TO AND BETWEEN EACH PAIR OF INLET ROWS. THE STOCK FLOWS FROM THE CHAMBER THROUGH A DISCHARGE CHANNEL AND TO THE HEAD BOX OF THE PAPER MACHINE.
