摘要: Noise-causing vibrations in the span of a tensioned web running over and away from an arcuate guide surface area of a circular perimeter fixed guide bar at a speed such that in the off-running angle between the web and the curved perimeter of the bar, air moving in the direction of the web in such angle would tend to follow the curvature of the bar (Coanda effect) and cause splitting of the air between the web and the bar, inhibited by locating spoiler means in a plane extending substantially tangentially from the off-running side of the arcuate guide surface area. The spoiler means is desirably in the form of one or more ribs providing surface in the tangential plane. Where the web span runs between spaced fixed circular perimeter bars, spoiler means may also be located in a plane extending substantially tangentially toward the on-running side of the arcuate guide surface of the bar located at the downstream end of the span.

摘要: An extended nip press has a heated backing roll, on the surface of which a paper web is preheated before it passes through the extended nip. The paper web is restrained on the surface of the backing roll to achieve post-pressing drying. During a portion of the post-pressing drying, the extended nip press may be arranged so that the paper web is not backed by the pressing/drying felt, thus allowing free venting from the web to occur. In some cases, this zone will be augmented by a vacuum assist unit to draw steam away. This high temperature press is capable of outgoing dryness in the range of sixty-five percent versus fifty percent for conventional technology. This combination of high temperature pressing and drying can be expected to improve the maximum strength of the web by approximately 20 percent or more over conventional pressing methods. Two high temperature press dryers of this invention may be combined to achieve outgoing dryness of approximately seventy percent.

摘要: The press section of a papermaking machine has two conventional presses followed by two or three presses including one heated Extended Nip press thereby allowing control of the two-sidedness of the web by balancing the temperature and pressure of the Extended Nip Press with the pressure and temperature of the additional presses to form a one-sided sheet. The use of smooth high temperature press felts can aid in the reduction of two-sidedness of the formed web. The dryer section may alternatively add a fifth press utilizing the first dryer roll as the backing roll, two Extended Nip presses, a heated Extended Nip press followed by a heated conventional press, or a heated Extended Nip press in the third pressing position followed by a conventional heated press utilizing the first dryer as the backing roll.

摘要: A spreader bar apparatus is disclosed for separating slit portions of a web. The apparatus includes a first spreader bar which extends in a cross-machine direction relative to the web. The first spreader bar is bowed relative to the slit portions such that the slit portions are separated axially relative to each other when the slit portions are guided around the first spreader bar. A second spreader bar is disposed downstream relative to the first bar and extends in a cross-machine direction relative to the web for guiding the separated slit portions. The second bar is bowed relative to the separated slit portions such that each of the slit portions disposed downstream relative to the second bar is disposed parallel to each other. A first and a second porous layer are connected to the first and second bars respectively such that when the bars are connected to a source of pressurized air, air flows through the bars and the porous layers towards the slit portions for generating respectively a first and second air cushion. The cushions reduce the frictional resistance between the moving slit portions and the bars. Additionally, the air cushions reduce the noise level caused by movement of the slit portions when the slit portions move relative to and are guided by the spreader bars.

摘要: A high temperature pressing roll has a cast or formed steel roll which is coated with a molybdenum-containing alloy. The preferred alloy has 14 to 16 percent molybdenum, 28 to 30 percent nickel, 30 to 34 percent chromium, 1.2 to 1.8 percent silicon, 4 to 4.5 percent boron, a maximum of 0.2 percent carbon and copper between 3 and 3.8 percent with the balance being iron. The roll is first coated with a bonding coating consisting of nickel and chromium. This bonding layer is then flame sprayed or plasma sprayed with a molybdenum alloy. The coating once applied is ground to a 30 RA or smoother surface. The molybdenum alloy is sprayed on to achieve a surface depth of approximately forty thousandths of an inch.

摘要: A heated extended nip press apparatus and method are disclosed for pressing water from a formed web. The apparatus includes a frame and a backing roll rotatably supported by the press frame. A press device is connected to the press frame and movable relative to the backing roll. The press device cooperates with the backing roll for defining therebetween n extended nip for the passage therethrough of the web. An endless looped blanket extends through the extended nip such that the web is disposed between the blanket and the backing roll. Additionally, the press device includes an arrangement for selectively changing the pressure applied on the blanket along a machine direction relative to a further pressure applied for moving the press device relative to the backing roll such that optimum web properties are obtained and delamination of the pressed web is inhibited.
