A support structure in the form of individual support segments made from sintered oxide ceramics are arranged to extend over the width of the apparatus and are in contact with one another, with a plurality of the segments being arranged consecutively in the direction of the course of the wire devices, the segments having a maximum linear expanse of 700 mm per segment and having junction areas between consecutively arranged segments defining a gap for feeding cooling water to the guide wire devices. | ||||||
| 62 | Wire section in a paper machine | US345480 | 1982-02-03 | US4472244A | 1984-09-18 | Eino Haltsonen |
| A wire section in a paper machine includes an upper wire unit which is compact and easily exchangeable, if required, the construction of the wire section being such that old, single-wire planar wire machines can be converted to twin-wire machines. The paper machine wire section includes a lower wire having an initial single-wire run in which dewatering of a web takes place, and at least one upper wire unit following the initial single-wire run which defines a twin-wire dewatering zone with an adjacent run of the lower wire and in which dewatering of the web takes place through both the lower and upper wires. The twin wire dewatering zone is further defined by a curved, solid-cover forming shoe situated within the upper wire loop and wherein the forming shoe is preceded by a curved dewatering zone where dewatering is mainly through the upper wire. The upper wire unit further comprises apparatus situated mainly above the forming shoe for conducting water dewatered from the web through the upper wire to at least one side of the paper machine substantially without the use of suction. | ||||||
| 63 | Dewatering apparatus for longitudinal wire papermaking machines | US392622 | 1982-06-28 | US4447295A | 1984-05-08 | Alfred Bubik; Hans Dahl; Herbert Holik; Rudiger Kurtz; Werner Seider |
| A dewatering apparatus contains a longitudinal wire and an additional wire which is guided, conjointly with the longitudinal wire, along a section of such longitudinal wire over a domed or arched surface. This domed or arched surface is formed, for instance, by the jacket or outer surface of a dewatering cylinder arranged within the wire loop of the longitudinal wire. The longitudinal wire is provided with a headbox and extends forwardly and after the dewatering apparatus essentially in a wire plane, above which upwardly rises the domed surface. Both of the wires are guided out of the wire plane over a dewatering shoe arranged within the wire loop of the additional wire towards the domed surface and from such--if desired over a deflection roll arranged beneath the wire plane--again towards the wire plane, where both wires separate from one another. Due to this arrangement there is realized a guiding of both wires which improves the dewatering action and is extensively independent of the elevational position of the wire plane, and at the same time affords a constructional simplification of the papermaking machine. | ||||||

| 67 | Method for use in the wet end of a paper machine, cardboard machine or an equivalent web forming machine | US12091783 | 2006-10-20 | US08133355B2 | 2012-03-13 | Martti Pulliainen; Mikko Vepsalainen; Jukka Rautiainen; Matti Hakkinen; Pekka Kylliainen; Seppo Karine; Jari Rasanen; Kirsi Partti-Pellinen; Ari Johansson; Isto Heiskanen; Jyri Jarvi |
| The invention relates to a method in the wet end of a web forming process. In the method, at least one electrode pair (102, 103) is placed in the wet end. The electrode pair (102, 103) is supplied with a current/voltage from a power source (100), so that an electric field is set up between the electrode pair (102, 103), causing the material particles in the pulp suspension in the wet end to be electrically charged in a desired manner and to move in a desired manner in the pulp suspension in the wet end. The current/voltage of the power source (100) is controlled by means of a measuring and control unit (101) so as to cause the material particles in the pulp suspension to be electrically charged and to move in a desired manner, thus allowing the retention, formation and orientation of the material particles in the pulp suspension to be substantially improved. | ||||||
| 68 | Reel shaft and reel-up for reeling a paper web | US10331112 | 2002-12-27 | US07503520B2 | 2009-03-17 | Sören Sven Eriksson; Tord Gustav Gustavsson; Anders Tommy Lindén |
| A reel shaft for reeling a paper web in a reel-up, which reel-up includes at least one unit that is mobile in the longitudinal direction of the paper machine and supports a pair of opposite engagement members each of which includes an engagement part, which engagement parts are arranged for rotatably carrying and detachably engaging the reel shaft during reeling. In accordance with the invention, the reel shaft is free of a support shaft and has a self-supporting, tubular sleeve substantially formed of fiber-reinforced plastic, which sleeve has an envelope surface on which the initial wrapping of the paper web shall be performed, and also an internal surface defining an axial channel terminating in axial openings at the ends of the reel shaft. The invention also relates to a reel-up for such reel shafts. | ||||||
| 69 | Shortened layout from dryer to reel in tissue machine | US10683243 | 2003-10-10 | US07192506B2 | 2007-03-20 | Anders Tommy Lindén |
| A dry end of a tissue machine is made shorter by close-coupling a reel-up to the drying section and supporting the web from the drying section to the reel-up by a foil or a belt such that web stability is maintained, thus allowing high-speed operation. The foil's downstream edge can form a nip with the paper roll and nip load can be controlled by controlling pivotal movement of the foil. The reel-up can include a calendering belt for calendering the web as it passes through a nip between the belt and a reel drum supported on the belt, and a rotatable reel spool on which a paper roll is wound in nipping engagement with the reel drum. Alternatively, the reel drum can be eliminated and the paper roll can be supported on the belt. A composite shaftless core for winding is also disclosed. | ||||||

| A property of a paper web is measured using one or more reflectance measurement sensors emitting measuring beams onto the web and receiving the beams reflected from the web, from which the web property is deduced. The web is supported on a web support during the measurement, such as on a passive or active airfoil or fabric. One or more measurement sensor(s) can be integrated within an active airfoil, and can comprise a plurality of optical fibers having sensing ends arranged in the airfoil such that the sensing ends of the fibers face the moving paper web through one or more apertures in a web-supporting panel of the airfoil. Alternatively, a traversing sensor can be mounted within the airfoil. Other embodiments include a reflectance sensor mounted adjacent an airfoil or other web support such as a through-air drying fabric or a support belt for the web. | ||||||

| 77 | Method for forming a uniform continuous web of paper | US3705847D | 1970-09-21 | US3705847A | 1972-12-12 | STILES LESTER W |
| A METHOD AND APPARATUS ARE DISCLOSED FOR FORMING A CONTINUOUS WEB OF PAPER UTILIZING THE PRINCIPLES OF ELECTROPHORESIS AND ELECTRO-OSMOSIS. A UNIFORM AQUEOUS DISPERSION OF PAPER-MAKING FIBERS IS FLOWED BETWEEN A PAIR OF HORIZONTAL, SPACED-APART, ELECTRICALLY CHARGED ENDLESS BELTS WHICH SERVE AS ELECTRODES FORMING A DEPOSITION ZONE. THE PAPER-MAKING FIBERS ARE ATTACHED TO ONE ELECTRODE BY ELECTROPHORESIS AND WATER TO THE OTHER ELECTRODE BY ELECTROOSMOSIS. A ELECTROMECHANICAL VIBRATOR VIBRATES THE TROUGH JUST PRIOR TO ENTRY OF THE AQUEOUS DISPERSION BETWEEN THE ELECTRODES TO MAINTAIN THE FIBERS IN SUSPENSION AND UNIFORMLY DISPERSE THEM WITHOUT FLOCCULATION. ELECTRICALLY NONCONDUCTING GUIDE BLOCKS ARE MOUNTED IN CONTACT WITH THE EDGES OF THE ENDLESS BELTS IN THE AREA OF
THE ELECTROSTATIC FIELD TO MAINTAIN THE PROPER ELECTRODE SPACING. AFTER THE ELECTRODE AND FIBER MAT ARE REMOVED FROM THE DEPOSITION ZONE, THE FIBER MAT IS SEPARATED FROM THE ELECTRODE SURFACE BY AN ADJACENT ELECTRICALLY CHARGED SURFACE WHICH TRANSFERS THE MAT. RESIDUAL WATER IN THE MAT IS REMOVED SIMULTANEOUSLY WITH THE TRANSFER BY ELECTROOSMOSIS. THE CELLULOSE FIBER MATS, PARTICULARLY USEFUL AS CAPACITOR TISSUE, HAVE BETTER ELECTRICAL PROPERTIES THAN CAN BE OBTAINED ON CONVENTIONAL PAPER-MAKING MACHINES. |
