    摘要: A method and apparatus in ropeless tail threading in a multi-roll calender is disclosed wherein the threading tail is guided through the multi-roll calender in such a way that, before the multi-roll calender, the threading tail is guided first of all to the broke processing and then cut when the tail threading begins. The tail threading takes place in stages, so that at least once during the tail threading the threading tail in connection with the multi-roll calender is guided to broke processing and cut, after which the tail threading is continued, once the previous stage has succeeded.

    摘要: The present invention relates to a method for calendering a moving web (1) of paper or board. The web (1) is passed to a calender (2) and calendered therein. At least one quality of the calendered web (1) is measured at a first measurement point (3) adapted at a location downstream from the calender (2). Additionally, at least one quality of the web (1) entering the calender (2) is measured at a second measurement point (4) adapted at a location between the calender (2) and the preceding section of the line. A control variable (6) affecting the calendering effect on the calender (2) is controlled by a feedback control scheme based on the measurement result obtained from said first measurement point (3) and a control variable (9) affecting the processability of the web (1) to be calendered is controlled by a feedback control scheme based on the measurement result obtained from said second measurement point (4).

    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: The invention relates to a method for positioning a shoe of a shoe press/shoe clender in a paper machine. In the method, the position of the shoe (11) of the shoe calender/shoe press is measured and, based on the results of the measurement, the position of the shoe is controlled so as to be as desired in the direction of nip compression. The invention also relates to an arrangment for positioning a shoe of a shoe press/shoe calender in a paper machine, which arrangment comprises a shoe roll (10) or equivalent which includes a shoe (11) and hydraulic cylinders (12) connected thereto for moving the shoe (11). The arrangement comprises further at least two measuring devices (15) for measuring the position of the shoe (11) and means (12) for controlling the position of the shoe (11) based the results obtained by means of the measuring devices so as to be as desired in the direction of nip compression.
