Abstract: An apparatus is disclosed for drying a web of paper emerging from a press section of a papermaking machine. The apparatus incudes a first dryer section means for initiating the drying of the first side of the web. A first transfer arrangement transfers the web from the press section to the first dryer section. A second dryer section is disposed downstream relative to the first dryer section for initiating the drying of a second side of the web, the second side of the web being opposite to the first side thereof. A first dryer transfer arrangement transfer the web without open draw between the first and second dryer sections. The first dryer transfer arrangement permits both threading of the web without the assistance of threading ropes and the drying of both sides of the web.

Abstract: A wide area type of wet press for dewatering an endless traveling web, such as paper, wherein a shoe having a curved face is applied to a traveling belt which travels through a high pressure zone between the shoe and a rotating backing roll. The nip line of the most intense nip pressure along the length of contact of the shoe over the backing roll is selectively located, as desired, by pivotally supporting the shoe about two, parallel, longitudinally extending axes which, in turn, are supported on separately controlled hydraulic pistons. The pressure profile of the nip pressure over the face of the shoe can also be altered by controlling the hydraulic pressure in the support pistons.

Abstract: In a papermaking machine, a method and mechanism for delivering stock to a dewatering web including a pressure headbox with a narrowing slice opening, a receiving throat either with a single traveling forming wire or a pair of traveling forming wires, bridging the space between the headbox opening and the wire so that the stock jet is contained without a free surface, and applying a trailing flexible element opposite the stock in a single wire machine or against one wire in a twin wire machine with the force and location of the trailing element controlled by a series of push rods arranged parallel in a cross machine direction.

Abstract: An apparatus is disclosed for removing fluid from a fibrous web. The apparatus includes a press member and a blanket which cooperates with the press member for defining therebetween an elongate pressing section such that the web is pressed between the press member and the blanket during passage through the pressing section. An elongate press shoe urges the blanket towards the press member such that when the web passes through the pressing section, fluid is removed from the web. A heater is disposed adjacent to the press member for transferring heat to the web such that when the web passes through the pressing section, the web is subjected for an extended period to increase pressure and temperature so that water vapor generated within the pressing section during the passage of the web through the pressing section forces the fluid in the liquid phase away from the web. The press member has an outer surface which cooperates with the web.

Abstract: A method for winding a traveling web into a wound web roll supported on a two-drum belt winder having a belt looped over two fixedly mounted support drums. The tension in the belt is adjustable from an initially relieved tension condition where a depression is formed in the belt over the notch between the support drums. A new core is inserted in the depression and is wrapped by the on-coming paper web to begin forming a wound roll of paper. As the wound roll of paper increases in diameter, the tension in the looped belt is increased to provide greater support in the span between the nips of the wound roll over the belt against the support drums. Initially, a rider roll is also brought into nipping engagement with the wound paper roll. The nip load of the rider roll is gradually relieved as the diameter of the wound paper roll increases.

Each of the extremities defines an upstream edge and a downstream edge such that for each tube, the upstream edge is nearer than the downstream edge to the upstream end of the outlet.

Abstract: A piston apparatus for use in a controlled deflection roll includes a rectilinear-shaped piston having at least one side seal extending longitudinally in a slot in each side wall and an end seal in each end of the piston extending between the side seals. The end seals have at least one pair of intersecting surfaces at each end thereof which cooperate with a corresponding pair of surfaces of each side seal to move longitudinally relative to the piston and side seals to maintain a continuous seal peripherally about the piston. The continuous seal engages the side walls of a channel within the support shaft of the controlled deflection roll and a non-movable seal surface in each of two, opposed dams at either end of the channel in the support shaft. The side and end seals move with the piston relative to the support shaft and seal surfaces on the end dams.
