摘要： A SINGLE TIER DRYING SECTION IS DISCLOSED FOR DRYING A WEB. THE DRYING SECTION INCLUDES A DRYER AND A FELT ABOUT THE DRYER SUCH THAT THE WEB IS DISPOSED BETWEEN THE DRYER AND THE FELT FOR DRYING A FIRST SIDE OF THE WEB. A FURTHER DRYER IS DISPOSED DOWNSTREAM RELATIVE TO THE DRYER AND A FURTHER FELT IS GUIDED ABOUT THE FURTHER DRYER SUCH THAT THE WEB IS DISPOSED BETWEEN THE FURTHER DRYER AND THE FURTHER FELT FOR DRYING A SECOND SIDE OF THE WEB. A DRYER TRANSFER MECHANISM IS USED FOR TRANSFERRING THE WEB FROM THE DRYER TO THE FURTHER DRYER.

摘要： A self-loading controlled deflection roll has movable shoes disposed inside the roll shell, at the opposite ends and at the center of a central shaft, for displacing the external surface of the roll shell toward and away from a mating roll forming a nip with the controlled deflection roll. In order to ensure that both ends of the controlled deflection roll shell move evenly in a radial direction into nipping engagement with the mating roll, and to also ensure that the ends retract evenly away from nip engagement, a control system and method are provided for automatically adjusting the flow of hydraulic fluid, such as oil, which is used to displace the shoes at the opposite end of the central shaft. The control system and method make use of a mechanical linkage which is operated by movement responsive displacement of the shoes, the linkage positioning relatively movable parts of a control valve so as to increase or decrease the flow of hydraulic fluid to the respective end shoes, thereby ensuring that the end shoes move uniformly relative to each other.

摘要： A web support foil positioned adjacent to a Yankee dryer above a creping doctor. The foil supports the web as it leaves the dryer. Mounted to the top of the foil is an adjustable air deflector which is positioned tangent to the Yankee dryer. The air deflector blocks air moving along the web. A slotted opening draws air from a leading-edge pocket collecting fibers which are broken loose during the creping action. The web is held against the bottom side of the foil by one or more air jets which are directed over the bottom surface on the foil. The jets of air function as coanda air jets and prevent the web from sticking to the bottom surface of the foil while creating a Bernoulli effect which holds the web against the bottom of the foil.

摘要： A hydrostatic self-loading controlled deflection roll has a central, hydraulically operated shoe which extends substantially the entire cross-machine width of the rotating roll shell, and two outboard shoes disposed, in the cross-machine direction, outside of the nip loading zone. The use of the outboard shoes permits the use of a single, full-length nip shoe within the nip loading zone, which simplifies control and provides for more uniform temperature distribution. The outboard shoes also provide better crown control. The outboard shoes are preferably disposed within a head flange area of the roll, at the location where spherical bearings would normally be present in a conventional roll. A bearing ring is disposed axially outside of the head flange and around a portion of a bearing box at either end of the roll for rotatably supporting the roll shell about bearings in the bearing box. A barrier seal is disposed between the stationary roll shaft and the roll shell intermediate the bearings and outboard shoes.

摘要： An extended nip press apparatus is disclosed for removing water from a web. The apparatus includes a rotatable backing roll and an elongate shoe which cooperate with the backing roll for defining therebetween an extended nip for the passage therethrough of the web. The shoe defines a concave surface. A bearing blanket is movably disposed between the backing roll and the concave surface. The arrangement is such that the web is supported by the blanket with the web being disposed between the blanket and the backing roll. A lubricant is supplied between the concave surface and the blanket such that the blanket is slidingly supported by the concave surface during passage of the blanket through the extended nip. The concave surface encompasses a pocket defined by the shoe. The arrangement is such that the pocket is filled with lubricant flowing from the concave surface so that in the event of a wad of the web entering into the extended nip, the wad is yieldingly received within the pocket so that damage to the blanket by the wad is minimized.

摘要： A controlled deflection roll for a papermaking machine. The roll includes a roll shaft having a longitudinal axis, a roll shell surrounding the shaft, and a bearing pad assembly supported on the shaft to supportingly engage the shell and move the shell translationally relative to the shaft in a plane including the axis. In one embodiment, the bearing pad assembly includes a plurality of bearing pads. Each bearing pad is spaced apart in the cross-machine direction and has a contact surface engageable with the inner surface of the shell. The contact surface is in the shape of a parallelogram and defines therein at least one recess. The side edges of adjacent bearing pads are straight and parallel to each other and define gaps therebetween. The gaps do not extend along a plane which is perpendicular to the axis. In another embodiment, the bearing pad assembly includes at least one bearing pad having a contact surface and opposite edges. The contact surface has a contact surface portion engageable with the shell. The contact surface portion has a plurality of continuous contact surface portions extending between the opposite edges such that each of said continuous contact surface portions does not extend in a plane which is perpendicular to said axis. The roll further includes a hydraulic assembly independently actuating the plurality of bearing pads to selectively engage the shell and supplying lubricant between the support surfaces and the shell. A pressure profile and a temperature profile are created along the length of the shell. The bearing pads engage the shell such that the pressure profile and the temperature profile are substantially evenly distributed along the length of said shell.
