摘要： The invention relates to a process for producing multilayer fiber web (MLW) by joining two or more fiber webs (W1, W2, W3,...) together. The webs (W1, W2, W3,...) to be layers of the multilayer web (MLW) are joined in hot pressing zone of a joining unit (10) in which by pressing a moist fiber web together with another fiber web a tight bond between the webs that create layers of the multilayer fiber web is achieved.

摘要： The invention relates to a method of making surface-sized paper/board. The web to be treated in the method is after surface sizing passed to a treatment process for providing a desired drying shrinkage and/or increase of drying stresses to create thereby a desired effect on the flexural strength and/or bulk of paper/board.

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： A method and an arrangement for controlling evaporation and moisture in a multinip calender (10) when a continuous fibrous web (W) is calendered in calendering nips (1, 2, 3, 4, 5) placed one after the other before the fibrous web is wound on a reel-up/winder (9). It is characteristic of the invention that, with a view to making the net evaporation from and the final moisture content of the web (W) constant when the running situations in the calender (10) change, the web is passed in the calender from the outlet of at least one nip into an air-float chamber (20) of the turning airborne type.

摘要： The invention relates to a method and arrangement for processing a wide paper or board web in connection with such a manufacturing method, in which a wide base web (14) is manufactured and the base web is processed in at least one processing stage before the separation of the finished product by cutting it transversely from the web on the production line. According to the invention, the base web (14) is divided at least once to form two part-webs (17, 18) before the separation of the finished product by cutting it transversely from the web and before the final processing stage preceding separation. At least one part-web (17, 18) formed in this manner is guided to a finishing stage before the separation of the finished product by cutting it transversely from the web on the production line.

摘要： The invention relates to a method for manufacturing a metal belt (102) for use in a paper/board machine or in a finishing machine. The method comprises producing a metal belt by placing side by side and/or in succession several metal belt blanks (10a; 10b; 10c) narrower than a final width of the metal belt in a number necessitated by the belt (102) of a desired width and length, and welding joints therebetween by friction welding, the joint developing a composition substantially similar to the basic material.

摘要： In the method for leading a web between calender roll nips (N), a web (W) is guided between the calender roll nips (N) in a loop which runs apart from the calender rolls, inside which loop an air pocket (3) is formed. The mass and/or heat flow in the air pocket (3) is prevented in the cross direction of the web by means of obstacles (5) placed in connection with the pocket.
