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.
