摘要： PROBLEM TO BE SOLVED: To provide a tissue web supporting apparatus capable of reducing paper breaks and the amount of dust occurring in scraping a tissue web from the surface of a yankee dryer. SOLUTION: This web supporting foil is installed in the vicinity of a yankee dryer over a creping doctor 24 and the foil supports a web when it is separated from the dryer. An adjustable air deflector 46 which is tangentially arranged on the yankee dryer is attached to the top of the foil. Air moving along the web is screened by the air deflector 46. An opening part with small holes sucks air from a tip pocket 44 for collecting fibers broken in creping treatment. The web is retained at the bottom side of the foil by one or more air jets directed toward the bottom of the foil. The air jets function as a Coanda air jet and generates Bernoulli's effect for retaining the web on the bottom of the foil while preventing the adhesion of the web to the bottom of the foil.

摘要： A controlled deflection roll (1) has a roll shell (2) which is hydrostatically radially supported by internally disposed hydrostatic shoes (3, 9). In order to axially position the roll shell (2), a mechanical locating link (23) is provided which is disposed externally of the roll shell (2). The link is coupled at one end to an element attached to the roll shell (2), and is coupled at an opposite end to a fixed support, such as a floor stand (7). The end of the roll at which the locating link (23) is disposed is thus axially fixed, while the opposite end of the roll remains free to float. The locating link (23) can be connected to an oscillator to oscillate the roll shell (2) axially during operation so as to distribute any non-uniformities in the roll shell (2) and thus to mitigate their effect on the sheet.

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 (1), and two outboard shoes (24, 26, 28, 30) disposed, in the cross-machine direction, outside of the nip loading zone. The use of the outboard shoes (24, 26, 28, 30) permits the use of a single, full-length nip shoe (3) within the nip loading zone, which simplifies control and provides for more uniform temperature distribution. The outboard shoes (24, 26, 28,30) also provide better crown control. The outboard shoes (24, 26, 28, 30) are preferably disposed within a head flange (17, 18) 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 (17, 18) 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 (1) intermediate the bearings and outboard shoes (24, 26, 28, 30).

摘要： 2149413 9411573 PCTABS00032 A self-loading controlled deflection roll (10) for forming a controlled pressure nip with another roll (4) along a nip line (N) with a hollow rotatable roll shell (14) rotatable on an axis (16) and a roll shaft (12) extending through the shell and radially supporting the shell along the nip line with axially facing surfaces (73, 73', 73'', 73''') on the shaft and rollers rolling on said surfaces supported on the rotating roll shell accommodating bending of the roll shaft relative to the roll shell fixing their relative axial positions. One roller (86, 87) is axially fixed and the other roller (90, 91) is mounted on a rocker arm (92, 93) loaded with the piston and cylinder (94, 95).

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 single tier drying section is disclosed for drying a web. The drying section includes a dryer and a felt guided 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 for forming a pressure nip with another roll has at least one support shoe mounted in a stationary support shaft for controlling the deflection of the roll shell in the direction of the nip. At either end of the controlled deflection roll, a pair of opposed guide shoes are slidably mounted on the stationary support shaft to apply pressure against the roll shell to stabilize the position of the roll shell relative to the stationary shaft. At least one guide shoe on either end of the roll is equipped with a compensating piston to permit its face surface to move radially outwardly relative to the guide shoe support on the stationary shaft. The guide shoes slidably reciprocate in planes parallel to the plane of the nip through the longitudinal axis of the roll and provide opposed, equal stabilization forces at substantially right angles to the plane of the nip. The guide shoes also have axially extending pads for bearing against annular end surfaces on the roll shell to maintain the roll shell fixed in the longitudinal direction relative to the support shaft during operation.
