摘要： A paper web is passed through a calendering nip that is formed between a roll which has been provided with a soft face and a heatable hard roll. The heatable roll is heated so as to plasticize the surface layer of the paper web that is placed at the side of the heatable roll, preferably so that the temperature of the surface layer in the calendering nip exceeds the glass-transition temperatures of the polymers contained in the paper. Before entering into the calendering nip, the paper web is moistened, so as to lower the glass-transition temperatures of the polymers contained in the paper, and pre-heated. The pre-heating of the paper web is carried out by bringing the paper web into contact with the heatable roll before the web enters the calendering nip and by, before the calendering nip, feeding steam or water onto the face of the paper web that is placed at the side of the heatable roll so as to improve the transfer of heat from the hot roll to the paper web.

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.

摘要： A system for maintaining calender rolls of a paper machine clean when producing high-gloss paper or coated paper, such as LWC or MWC. To prevent a coating agent, such as coating dye, from adhering onto and soiling a smooth surface of a calender roll, with an overheating phenomenon, the system has a second measurement station (10) provided with measuring and indicator means for producing an output indicating soiledness of the web (W) or a humidity profile. When the output of the second measurement station (10) indicates excessive soiledness or an uneven humidity profile, the system performs at least one of: cleaning the surface of the smooth-surfaced calender roll; changing the nip load in the calender (5); making a correction adjustment of the CD-directional humidity profile of the web (W); cutting the web (W) and conducting it into the pulper; and/or changing the running speed of the web (W).

摘要： In the method for paper web transfer in a paper machine or finishing apparatus for paper, a paper web (W) is transferred in a first machine portion (A) at a first travelling speed. In a second machine portion (B) following the first one in the travel direction of the web, the tail is transferred at a travelling speed lower than the first travelling speed. In the second machine portion (B) the tail (TB) is transferred independently without a draw connection to the web (W, TA) transferred in the first machine portion (A), the travelling speed of the tail (TA) transferred in the second machine portion (B) is increased, and a draw connection is established between the tail and the web (W, TA) transferred in the first machine portion.

摘要： The moisture profile and/or moisture gradient of a paper web of at least SC quality paper is controlled in a paper machine comprising a calender (1) which has at least two roll stacks (21, 22; 31, 32), one stack has at least three rolls and another has at least five rolls. The web is moisturized to a desired pre-moisture content M1 by a pre-moisturizer (7) before the calender. At least one intermediate moisturizer (3) is arranged between two roll stacks moisturizes the web to a desired intermediate moisture content M2 before the last roll stack (31, 32), in which the web is dried to a desired final moisture value M3. For continuously controlling and optimizing the moisture profile and/or moisture gradient of the web, the pre-moisturizing W1 of the web is controlled by a pre-moisturizer (7) control parameter which corresponds to the final moisture value M3 of the web.

摘要： A control device in particular in a multi-roll press (22 to 24) of a calender intended for the glazing of a continuous thin web, such as a paper web, which said press comprises a compensated upper roll (22), a compensated lower roll (24), and at least one press roll (23) fitted between the rolls. The control device itself comprises a press-load control circuit (B, C, D, 11, 14, 15; A, 29, 30), a compensation circuit (E, 16, 17) for the upper roll (22), as well as a compensation circuit (F, 27, 28) for the lower roll (24). According to the invention, both of the compensated circuits (E, 16, 17 and F, 27, 28) are, via their own feedbacks (12 and 13), connected to the control circuit (B), which is fitted so as to select the most slowly changing one from among the signals of the feedbacks (12 and 13) and to brake down the roll (22 or 24) whose compensation is being varied most rapidly. By means of the invention, the calender will always be loaded in a constant way, whereby a better paper quality and constant running values are obtained.

摘要： A roll comprises a rotatable mantle portion and a non-rotating shaft portion and, connected to the shaft portion, means for roll deflection adjustment. These means comprise a bushing or the like mounted around the non-rotating shaft portion at one roll end and being, by means of a bearing, in radially force transmitting contact with the roll mantle portion. The bushing is pivotably connected to the shaft portion at a position between the bearing and a second bearing between the shaft portion and the mantle portion at a position more remote from the roll end. The bushing is provided with a device for altering radially the position of the first mentioned bearing with respect to the shaft portion by altering the angle setting of the bushing with respect to the roll shaft portion.
