摘要： A method and an arrangement for manufacturing calendered paper or board particularly in the on-line manufacturing method. In the method, a base web is formed from a mixture of water and pulp supplied from the headbox and the web is dried by removing water over the press section and over the dryer section by heating. The formed web is calendered at least once to modify the surface on at least one of its sides. Before calendering the cross-direction thickness profile of the web is standardized and calendering is carried out by means of a long-nip calender, whereby good surface quality is obtained without losing the bulk or stiffness of the web.

摘要： In the method, a long nip (N) shoe calender formed of a shoe roll (10) and a thermo roll (20) is used. In calendering, a nip dwell time which is over 10 ms, advantageously over 20 ms, a nip pressure which is below 3 MPa, advantageously below 1 MPa, and a surface temperature of the thermo roll (20) which is over 200 °C, advantageously over 250 °C, are used. In addition, the board web (W) surface to be pressed against the thermo roll (20) is moisturized before the nip.

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 controlling a surface quality variable (300) in one or more fibre webs (3) in a shoe calender (1) comprising one or more calender nips. In each calender nip of the shoe calender, the overall loading pressure of the shoe element (8) and the loading pressure difference between the leading edge (8') and the trailing edge (8") of the shoe element are controlled so as to achieve minimum difference between the determined values (300") for the surface quality variables of the fibre web and the set values (300') for the same quality variables after the shoe calender.

摘要： The invention relates to a processing device and a method applying the same for processing a coated or uncoated fibrous web. The device comprises a belt (2) adapted to extend around a guiding element (3), at least one counter-element (5) being disposed outside said belt to provide a contact area with the belt, such that the belt (2) and the counter-element (5) establish therebetween a web processing zone for passing a web to be processed therethrough. The processing zone length is defined by means of the disposition of the belt's (2) guiding element (3) and/or by means of the design of the counter-elements (5). A contact pressure applied to a web in the processing zone is adapted to be adjustable within the range of about 0.01 MPa to about 70 MPa. The invention further relates to a safety paper, a method for producing said paper and a calender for making said paper, where the web is left with areas of desired shape uncalendered or less calendered.

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.
