| 101 | Constraint system for parallel cantilever shafts | US388015 | 1995-02-14 | US5553965A | 1996-09-10 | Fred M. Fuss; John A. Mesolella |
| Cantilever shafts (34, 40) support bearing assemblies (54, 56) over which is mounted a tuned compliance or constraint member (92) including flexure members (102, 104, 106) which minimize deflection of the shafts and improve operation of associated rotary tools (18, 20). An improved lock nut (70-86) permits precise installation of the bearing assemblies. | ||||||
| 102 | Cantileverable roll for roll pair of paper making machine | US296243 | 1994-08-25 | US5535670A | 1996-07-16 | Christian Schiel; Joachim Grabscheid |
| A cantileverable roll for use in a roll press, wherein the cantileverable roll cooperates with a backing roll. The cantileverable roll has a rotating surface and is either a solid rotatable roll body or a stationary roll body with a rotatable shell around it. A journal at each end of the cantileverable roll is supported in a respective bearing bracket. At one end of the roll, preferably the drive end, there is a non-rotating extension piece which extends out axially from the roll body and is fastened to the bearing bracket at that end. A tension bar or the like connects the extension piece to a stationary structural part and introduces force in the roll body which compensates for the weight of the roll when the other end of the roll is temporarily unsupported and the roll is cantilevered. The backing roll may also be cantilevered. The various techniques for supporting the one end of the roll by using the coupling element from the extension piece to the frame of the paper making machine are disclosed. The cantileverable roll and the roll press are particularly useful in a paper making machine. | ||||||
| 103 | Supporting connections between two rolls | US8454 | 1993-01-25 | US5400708A | 1995-03-28 | Andreas Meschenmoser |
| A roll assembly comprising a rotatable roll (1 in FIG. 2) and a second roll (2 in FIG. 2) cooperating therewith, in which a pressing element (17) to effect displacement between the rolls along a pressure plane of the roll assembly is located in one of the rolls (1,2) and in which both rolls are supported at either end by respective support members (5,6). Prior to operation of the roll assembly, dumbbell-like shaped connecting parts (7) installed in corresponding cut-outs (9) in the support members (5,6) are tensioned and thereby securely form-locked by actuating the pressing element (17). Locking action is released by subsequent deactivation of the pressing element (17) after which the connecting parts (7) can be withdrawn. Two principal advantages of this arrangement, are the compacter construction, enabled by the fact that the frame no longer bears the pressing forces of the roll assembly, and the ease and speed with which components such as rolls, roll jackets or felt belts can be changed. | ||||||
| 104 | Press roll for paper machines | US467003 | 1990-01-18 | US5012730A | 1991-05-07 | Christian Schiel |
| Press roll with a tubular cylinder, featuring on each of its two ends a roll head with a journal, specifically for use in a roll press consisting of the press roll and a backing roll with controlled deflection, for the treatment of web type material such as a paper web or the like. The inside surface of the tubular cylinder is so shaped across the web width that the shape of the flex line of the tubular cylinder will approximate during operation the flex line of the roll shell of the backing roll. This yields a press roll having a relatively thin-walled tubular cylinder which is lightweight. Nonetheless, an extensively constant line force is achieved in the press gap of the roll press across the web width. | ||||||
| 105 | Wet press with vibration control | US202094 | 1988-06-03 | US4902384A | 1990-02-20 | Helmut Anstotz; Bernhard Brendel; Gunter Schrors |
| A wet press of a paper-making machine includes a pair of rolls defining a roll gap through which the paper to be treated and belt-shaped felt are simultaneously conducted. The felt is guided in a closed loop path by additional rolls which include a tightening roll. The tightening roll can be tilted to reduce roll vibrations by tightening the felt to set vibratory marks formed in the felt at an angle relative to the transverse width of the felt and the roll gap. A controllable positioning device is provided which includes a motor operated by a controller during predetermined time intervals or as a function of actual vibrations sensed at the pair of rolls forming the roll gap to automatically vary the tilt angle. | ||||||
| 106 | Roller-type presses including methods associated therewith | US1862 | 1987-01-09 | US4826571A | 1989-05-02 | David R. Webster |
| In a press for papermaking comprising in combination, a pair of elongated rollers arranged one to another to provide an adjustable elongated nip therebetween, each of the rollers comprising a substantially rigid elongated shaft and a substantially rigid elongated sleeve overlying and rotatably supported upon the elongated shaft, the respective shafts extending outboard of the respective sleeve to provide two pairs of parallel spaced shaft outboard portions, the improvement comprising, in the case of each roller, providing a circumferentially extending running fit between the outer surface of the shaft and the inner surface of the sleeve defining an elongated annular chamber extending lengthwise of the sleeve. Other embodiments are disclosed which include the shaft being tubular and pressurized, lubricant in the annular chamber and a cable system for urging the rollers together. A splashguard is also provided for preventing water on the surface of the rollers from rewetting the paper. | ||||||
| 107 | Device for reducing the vibration of a press section constituted by two or more rolls pressed one against the other in a paper manufacturing machine | US401738 | 1982-07-26 | US4464986A | 1984-08-14 | Umberto F. Bollani |
| A mechanism for a press section of a papermaking machine including a press having first and second press rolls forming a pressure loaded press nip therebetween with a support frame and end bearings for the first roll with a support carrying the end bearings on the frame including first and second layers of deformable elastic material with a plate connected to the bearing between the layers of material and plates on the outer surfaces of the layers connected to the frame so that vibrational forces normal to the direction of movement of the web through the nip are passed through the layers of elastic material. | ||||||

| A PAPER WEB AND ITS SUPPORTING FELT OR A FELT ONLY IS DEWATERED EMPLOYING A PRESS ASSEMBLY COMPRISING A PAIR OF PRESS ROLLS IN NIP-DEFINING RELATION WHEREIN ONE OF THE PRESS ROLLS IS A BLIND DRILLED ROLL. ON THE OFF-RUNNING SIDE OF THE NIP THE FELT IS GUIDED AWAY FROM THE NIP ON THE SIDE OF THE NIP TANGENT PLANE OPPOSITE THE BLIND DRILLED ROLL AT AN ANGLE DEFINED BETWEEN THE FELT AND THE COMMON TANGENT PLANE. THE BLIND DRILLED ROLL IS DIPOSED IN A SAVE-ALL HAVING A SIDE WALL TERMINATING AT AN UPPER EDGE SPACED CLOSELY ADJACENT TO THE COMMON TANGENT PLANE AND THE NIP PREVENT WATER FROM ENTERING THE FELT ON THE OFF-RUNNING SIDE OF THE NIP.
