摘要： A web (W) is passed from a preceding treatment stage to a finishing device in which the web (W) is finished in the finishing device and from which finishing device the web (W) is passed further to a subsequent treatment stage. The web (W) is brought to a roll (11; 14) of the finishing device as supported substantially before a nip area (N1; N2). The web (W) is passed from the circumference of a roIl (12; 15) of the finishing device as substantially supported afler the nip area (N1; N2). A device for passing a web in connection with a finishing device of a paper machine causes a web (W) to be brought by the device to the circumference of a roll (11; 14) of the finishing device substantially before a nip area (N1; N2) and/or the web (W) can be passed from the circumference of a roll (12; 15) of the finishing device substantially after the nip area (N1; N2).

摘要： The surface of a web is monitored by a fault detection system (20), a machine condition monitoring system, a quality measurement system, a web moisture measurement and/or a web temperature measurement and the soiled part of the surface of the roll is detected and localized by means of a soiling monitoring apparatus (31, 35; 60). A control system (41) controls a cleaning device (40) to remove the detected soiling. As a web (W) travels in a paper or board production or finishing process or in finishing machinery the web and/or the surface of the roll is monitored and after a detected deviation the surface thereof is momentarily spread with a liquid while machinery is running at the same time as the web (W) travels over said roll surface.

摘要： The present invention relates to a method and assembly for opening the nips (9,10) of a calendar comprising at least two elements (1, 2; 3, 4) brought to a nip contact with each other, especially for performing the nip opening at a break or damage occurring in the web (5) being calendered. The tension of the web (5) being calendered is measured at multiple points over the cross-machine width of the web (5) and the calender nips (9,10) are opened when the measured web tension at a preset number of points over the cross-machine width of the web (5) has fallen to a limit value that by a decision-making algorithm monitoring the tension profile of the web (5) is interpreted to indicate a web break situation or other damage on the web (5) requiring opening the nips (9,10).

摘要： A take-out roll, spreader roll or equivalent roll for a web-like material having three parts linked with one another, namely, a middle part and two end parts, one on each side of the middle part. The middle part and end parts are pivotal with respect to one another for the purpose of bending the roll into a desired curved shape. The middle part is constructed to operate as a revolving axle of the roll which is mounted revolvingly on support members by end bearings. The end parts are mounted in the area of their axial inner ends on the middle part by articulation devices. The end parts are further mounted in the area of their axial outer ends, revolvingly and movably in a radial direction on support parts which are separated from the revolving parts of the roll by bearings arranged inward of the end bearings in the axial direction of the roll.

摘要： The invention relates to a method and apparatus for measuring the tension of a moving web. In the invention, a measuring beam (2)is curved so that a web moving over or under the measuring beam (2) forms an air cushion (3) of the air it transports between the measuring beam (2) and the web (1). The web (1) causes a force effect transmitted by the air cushion on the measuring beam (2). The tension of the web (1) is measured by measuring the force caused by the web (1) and transmitted by the measuring beam (2).

摘要： A threading device and a method for threading a tail of a web, wherein, for guiding the path of a tail separated from a full-width web in a paper machine or a paper finishing device, the threading device comprises a suction channel, placed at least partly in a paper machine portion and provided with a reduced pressure for gripping the tail, and transfer means for transferring the suction channel in the portion of the paper machine and simultaneously for releasing the tail to the portion. In the method for threading of the tail, before threading the full-width web through a portion in a paper machine, the tail is separated from the web, the tail is cut, and the tail is conveyed in the portion of the paper machine, after which the full-width web following the tail in a continuous manner is conveyed to the portion, by providing a reduced pressure in a suction channel, by transferring an inlet opening of the suction channel close to the tail separated from the web, by transferring the tail into the suction channel by means of the reduced pressure prevailing therein, and by releasing the tail to the portion of the paper machine by transferring the suction channel and particularly the inlet opening in the direction of the portion of the paper machine.
