摘要： A method for grinding a roll, in which method a roll (2; 25) in a paper or paper- board machine or a corresponding machine for processing a fibrous web is ground by a grinding device (1; 15) installed in the machine, and in which method an abrasive tool (12; 16) of the grinding device (1; 15) is fed against the surface of the roll (2; 25) by a feeding device (11 ) controlled by a control device. In the method according to the invention, the abrasive tool (12; 16) is fed against the surface of the roll (2; 25) at a speed which is lower than the speed of change in the distance between the abrasive tool (12; 16) and the surface of the roll (2; 25) in the radial direction of the roll (2; 25) when the roll (2; 25) is rotating, as well as in such a way that the abrasive tool (12; 16) first grinds only the peak points of deviations in circularity of the roll (2; 25) and then gradually larger and larger areas as the grinding proceeds and the deviations in the circularity decrease. The invention also relates to an apparatus according to the method of the invention.

摘要： The invention relates to a seal for a suction roll of a paper or board machine, said seal being placed inside a rotating shell of the suction roll and having a system for monitoring the wear of the seal (22) disposed in connection with the seal (22), said monitoring system comprising means (23, 24) for monitoring the wear of the seal (22). The means for monitoring the wear of the seal comprise an arrangement (23, 24; 27; 30, 31, 32, 33, 40; 37) for determining the need for replacement of the seal (22) based on information about the wear of the seal (22) without interrupting the operation of the suction roll.
摘要翻译：本发明涉及一种用于纸或纸机械的吸辊的密封件，所述密封件被放置在吸辊的旋转外壳内，并具有用于监测与密封件相关联设置的密封件（22）的磨损的系统（ 22），所述监测系统包括用于监测密封件（22）的磨损的装置（23,24）。用于监测密封件磨损的装置包括用于基于关于磨损的信息来确定更换密封件（22）的需要的装置（23,24; 27; 30,31,32,33,40; 37）密封件（22），而不中断抽吸辊的操作。
