摘要： In the method for treating the surface of the web, liquid is added on the surface of a paper or paperboard web (W), possibly with other constituents. The absorbency of the surface of the paper or paperboard web is increased before liquid is brought on the surface of the web or simultaneously with bringing the liquid on the surface of the web. The method is used for wetting the surface of the web before calendering, or for coating the web in surface sizing or pigmenting. The absorbency of the surface is increased before bringing the liquid for example by means of a corona treatment, a flame treatment, an ozonization or by adding steam.

摘要： The present invention relates to an applicator apparatus (10) for a film-transfer coater. The applicator apparatus (10) includes an applicator chamber (2) bordered by an area (B) on the surface of said rotating applicator roll (1) and by an applicator apparatus (10) comprising a doctor (4, 12) adapted to extend in the direction of the longitudinal axis of the roll essentially over the width of the roll (1). The chamber is further bordered by a dam member (3, 15) located in front of the doctor (4, 12) in regard to direction of rotation of said roll (1) so as to extend in the direction of the longitudinal axis of the roll essentially over the width of the roll (1). The applicator apparatus further includes means (6) for feeding the web treatment material into applicator chamber (2) and means (7) for feeding steam into the gap between the applicator roll (1) and the dam member (3, 15) for lubricating the dam member (3, 15).

摘要： Method and arrangement for coating a paper or board web, wherein the web (1) to be coated is brought to a film transfer coater and taken to a nip (12) between the film transfer roll (3) of the coater and its backing roll (4), and coating mix is applied onto the surface of the film transfer roll (3). The web (1) is taken through the nip (12) between the rolls (3, 4) and the rolls (3, 4) are turned whereby the coating mix applied onto the applicator roll (3) is at least partly transferred onto the surface of the web (1). According to the invention the web (1) is supported through the nip (12) by means of a belt (2) travelling at the same speed as the web, the belt having been arranged to travel round the backing roll (4). The web (1) is taken onto the surface of the belt (2) prior to the nip (12) and separated from the belt (2) after the nip, and it is pressed against the film transfer roll (3) by means of the belt (2) and the length of the path covered in contact with each other by the web (1) and the film transfer roll (3) is controlled by varying the position of the web (1) and the belt (2).

摘要： The invention concerns an equipment and a method in handling of doctor blades for a paper/board machine. The doctor blade (T) will be placed against the face of a roll in the paper/board machine so as to keep said face clean and to service said face. A doctor blade blank (T) is taken from a doctor blade roll (10a1, 10a2, 10a3 ...), i.e. from a reel. The equipment comprises a cut-off device (14a1, 14a2 ...) for cutting off the doctor blade material to the desired pull-out or blade length.

摘要： The invention relates to a roll for a paper or board machine comprising axle journals on whose support the roll is arranged to revolve, end flanges with which the axle journals are connected, and a mantle which is connected with the end flanges. The mantle is provided with a number of openings extending through the mantle and/or recesses (15) formed into the outer surface of the mantle, which openings and/or recesses form a regular pattern. Solid connecting portions in the outer surface of the mantle around said openings and/or recesses (15) are opened so that, from each opening and/or recess (15), there is a connection, provided in the form of a groove or an additional recess (16, 17) extending into the outer surface of the roll mantle, with at least each of the openings and/or recesses (15) closest to it.

摘要： The invention relates to an apparatus for continuously reeling a paper web (W), especially a high-loss magazine paper web, around a reel spool (68). The apparatus comprises means for guiding the paper web towards the reel spool, means for winding the paper web around the reel spool to form a paper roll (PR), and means for positioning the paper web on the roll (PR) in different axial positions with respect to said reel spool (68). The means for positioning the paper web on the roll in different axial positions comprises oscillating means (66, 65) provided for an oscillating movement of the reel spool (68) in cross direction of the paper web (w).

摘要： The pressure roller reel-up for reeling of a web (W) onto a roll (R) contains a roller (1) via which the continuous web (W) entering the reel-up is arranged to wind around a reeling axle (3) arranged rotatably in a reeling position. The reel-up also comprises a load device (4) for pressing the roller (1) against a roll (R) being formed of the web around the reeling axle (3) in order to form a reeling nip (N) between the roller (1) and the roll (R). The roller (1) is inside a belt loop (2) laid against the periphery of the roll (R) within a given path length (L) after the reeling nip (N) formed between the roller (1) and the roll (R).

摘要： The invention relates to a method in the calendering of a paper web, wherein the paper web (W) is passed through a calendering nip (N) formed by two rolls (11, 12). Of the nip rolls at least one roll (12) has been made soft-faced by means of a coating (13) of a polymer or equivalent material or by means of a band passed over said roll and running through the nip (N). The profile of the calendering nip (N) is regulated in order to compensate for any flaws present in the web (W) entering the calender (10), and in the invention the regulation of the profile is carried out during the running of the machine by varying the properties of the coating (13) or, correspondingly, of the band on the soft-faced roll (12) locally in a direction transverse to the machine direction. Preferably, the properties of the coating (13) or the band are varied by means of heat. The invention also relates to a calender that makes use of the method.
