摘要： A roll for use in the manufacture of paper and board, a press roll, in particular a center roll in a press, a backup roll for an extended-nip press roll, a hot press roll, or equivalent, which is in direct contact with a wet paper web, or a calender roll, a method for manufacturing the same and a coating composition therefor including an adhesion layer arranged on the frame part of the roll and a ceramic layer arranged on the adhesion layer. The ceramic layer has a thickness of from about 100 &mgr;m to about 2000 &mgr;m and includes from about 50% to about 95% by weight of Cr2O3 and from about 3% to about 50% by weight of TiO2, or from about 50% to about 80% by weight of Al2O3 and from about 20% to about 50% by weight of ZrO2, or exclusively Al2TiO5. The outer face of the ceramic layer is finished until the roughness Ra is from about 0.2 &mgr;m to about 2.0 &mgr;m and/or the porosity of the outer face of the roll is from about 1% to about 20%. In addition to or instead of TiO2, the ceramic layer may contain oxides of aluminum, silicon, zirconium, magnesium, manganese, tin, tungsten and mixtures thereof.

摘要： The invention concerns a heated roll and a method for heating of a roll, in particular of a press roll or calender roll in a paper or board machine. The roll has a hollow, tubular roll mantle. According to the invention, the roll is heated with electric current by means of electrical resistors fitted inside the body material of roll mantle. The heating is preferably applied to the roll substantially at the proximity of the face of the roll mantle, and the electric current may be supplied to the electrical resistors from the ends of the roll through glide rings.

摘要： A sealing strip of a suction roll (4) for a material web machine includes a longitudinal strip element (3) and a longitudinal holder (2) shaped as a U profile open in the direction of a facing surface (41). An element first layer (31) is an easily adjusting material and a second layer (34) is a stiffer material in the loading direction than the first layer. The strip element may be loaded so it or its edge does not substantially bend in the direction of movement of the facing surface. To optionally reduce the effect of abrasion: an inner mantel surface is treated by grain blasting, thermal injection coating, chemical or electro-chemical precipitation coating and/or polymer-based coating; and/or a lubricant or additive is fed between surfaces abrading against each other; and/or at least part of suction holes in a wall of the mantel are broached (71).

摘要： The invention concerns an equipment and a method in the transfer of a paper/board web in a paper or board machine. In an embodiment of the invention, the dryer section comprises at least one group of drying cylinders in which, instead of a conventional wire draw, a transfer belt (H100) is employed, to which the web (W) is affixed by effect of adhesion and which transfer belt is passed over drying cylinders (K1, K2, . . . ) and reversing rolls (E1, E2, . . . ) and further in said group (RI) of drying cylinders in the dryer section. The invention also concerns a method in the transfer of the web (W) in the dryer section (K) of a paper/board machine. In an embodiment of the invention, the web (W) is passed, while meandering in loop shape and while adhering to the face of the transfer belt (H100), from a drying cylinder (K1) in the group (RI) of drying cylinders in the dryer section (K) onto a reversing roll (E1) and further from the reversing roll onto the next drying cylinder (K2) and further in the group (RI) of drying cylinders.

摘要： A method and system for monitoring a separation process of a web in a paper machine in which the web is separated from a roll and passed into a free draw, which is preferably the first free draw of the web in the paper machine. A separation point of the web from the roll and a difference in speed of the web across the separation point, i.e., the draw difference, are measured. Cause-to-effect ratios in the separation process are established, e.g., in a data collecting system or analysis system, based on the measurements of the separation point and the speed difference. At least one additional process or running parameter of the paper machine is measured and the measurements of the separation point and the speed difference are compared with the additional process or running parameter(s) to thereby determine the manner in which the separation process of the web is affected by the additional process or running parameter(s).
