摘要： The invention concerns a method in film transfer coating, in which the coating agent is applied as a film (F1, F2) onto the face of at least one of the rolls (12, 16) that form a film press nip (N), from which roll face the coating agent is transferred in the nip between the rolls (12, 16) onto the paper or board web (W') running through the nip. According to the invention, in the coating process, formation of coating-agent mist is prevented at the outlet side of the film press nip (N) so that steam jets are applied at least to the side of the web (W) that is being coated. The steam jets are passed favourably to the outlet side of the nip (N), and the steam jets are preferably passed substantially to the point of separation of the web (W') from the film press roll (12, 16). The invention also concerns an equipment intended for carrying out the method.

摘要： The invention concerns a method for two-sided coating of a printing-paper web with a coating paste or equivalent. In the method, the paper web (W) is passed through the coating part (1) of the paper machine, in which the first side of the web (W) is coated in the first coating station (10) of said coating part, and the coating-agent layer produced on the face of the web (W) is dried at least partly by means of a first drying unit (15, 16, 17). The second side of the web (W) is coated in the second coating station (20) of the coating part (1), and the second coating-agent layer produced on the face of the web (W) is dried at least partly by means of a second drying unit (25, 26, 27). The coating-agent layers are formed onto the paper web (W) alternatively by spreading the necessary amount of coating agent by means of a coating device (13, 24) as a film onto the face of a film press roll (12, 22), from which the coating agent is transferred in the nip (N1, N2) between the film press roll (12, 22) and the back-up roll (11, 21) as a coating-agent layer onto the paper web (W), or by forming the coating-agent layer directly onto the paper web (W) by means of a blade coating device (14, 23) that coats the web face while using one of the film press rolls (12, 22) as the back-up rolls of the blade coating devices (14, 23).

摘要： A method and an arrangement for spreading a treating agent, for example, size or a coating onto a moving surface in the manufacture of the web-shaped folios or paper and paperboard and various sheet products in particular. In the method, the treating agent is fed into at least one feeding chamber (3) and the agent is directed from the feeding chamber (3) onto the moving surface (1). Jets are formed from the treating agent by directing the agent through at least one nozzle plate (6) comprising openings (10) that are defined by the nozzle plate (6) around the entire periphery, and the formed jets are applied directly onto the moving surface (1).

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).
