Method in film transfer coating and equipment intended for carrying out the method

摘要

Method and arrangement for coating a web in a film press nip defined by a pair of rotating rolls and through which the web runs and in which a coating agent is applied as a film onto a face of at least one of the rolls and transferred in the nip from the face of the roll(s) onto a respective side of the web to thereby coat the respective side of the web. Steam jets are applied to each side of the web that is being coated to prevent formation of coating-agent mist at a web-outlet side of the nip. The steam jets can be directed from a location after the nip to the web-outlet side of the nip and/or substantially to a point of separation of the web from contact with the roll(s).
