摘要： The present invention relates to a calendering arrangement for a paper machine for producing higher-gloss paper grades, in particular paper grades with a Hunter gloss % above 40. In accordance with the invention, the arrangement comprises, as a combination, pairs of calendering units (1, 3) disposed in the machine direction one after the other and apart from one another, which pairs are each formed of separate and different calendering units (1, 3) and in each of which the nip load in the latter calendering unit (3) is higher than the nip load in the preceding calendering unit (1). Advantageously, the calendering unit (1) placed first in the machine direction is an on-line long-nip calendering unit (1) and the calendering unit (3) placed after that in the machine direction is an on-line or off-line supercalender.

摘要： A nip is formed between a backing roll (10) and a loading roll (20). The loading roll (20) is comprised of a stationary support structure (21) and, adapted to run about the same, a flexible mantle (22) supported by its inner surface (22a) on said support structure (21) by means of at least one supporting member (23) serving to press said flexible mantle (22) against said backing roll (10). The loading roll (20) includes further at least one essentially axially aligned row of discrete pressure medium feed points (25, 26), whereby a pressure and/or flow rate controlled flow of pressure medium can be fed through the feed points (25, 26) of said at least one row against said inner surface (22a) of said mantle (22). According to the method, the pressure medium fed through said feed points (26) is used cross-machine direction (CD) profiling of the paper or board web passing through the nip (N).

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： This publication deals with a heatable and/or coolable roll, i.e. a thermo roll, of a fibrous web machine for the treatment of a fibrous web, for example for pressing and/or calendering the fibrous web in contact, i.e. in a nip, between the thermo roll and a backing member which is in contact with the thermo roll or for drying or cooling the fibrous web on the shell surface of the thermo roll. In addition, a semi-finishedproduct of a thermo roll and methods for manufacturing and using a thermo roll are discussed.

摘要： A method and a device for calendering paper in a calender which comprises at least one calender unit (10; 110) in which a first calendering nip (N1; N3) is formed between a heatable calender roll (16; 116) and an extended-nip roll (12; 112), which nip is an extended nip, through which a paper web (W) is guided to run in order to calender the paper on at least one side. In the calender unit (10; 110), a second calendering nip (N2; N4) is formed with the heatable calender roll (16; 116) and a third calender roll (17; 117), which nip is a roll nip, and the paper web (W) is guided to run through said roll nip (N2; N4) such that, in both calendering nips (N1, N3; N2, N4), the same side of the paper web (W) is in contact with the heatable calender roll (16; 116).

摘要： The invention relates to a method for monitoring and storing the properties of various components (1) of a paper/board or pulp and finishing/converting machine (20) and the changes taking place in them and/or the ambient conditions and the changes taking place in them, and for transmitting this data to the control unit (10) of the paper/board or pulp or finishing/converting machine (20) and/or to a separate data processing system (4). In the component (1) is arranged a memory unit (2) accompanying it, in which can be written or which can be read electrically, by magnetisation or optically, in which memory unit are stored at least those properties (A) of the component (1) which affect the control values of a paper/board or pulp or finishing/converting machine (20). The method and device also comprise data transmission means (9b, 3b) for transmitting the data stored in the memory unit (2) to the control unit (10) of a paper/board or pulp or finishing/converting machine (20) and/or a separate data processing system (4).
