ABSTRACT OF THE DISCLOSURE Apparatus for coating a web, such as paper or board web, comprises a coating nip formed between a rotating counter roll and a smoothing member, or between two smoothing members, through which the web to be coated is passed with a coating substance being applied to the web before is passes through the nip. The apparatus comprises an arrangement by which the linear load and/or the distribution of the linear load in the coating nip is adjustable to control the quantity and/or the distribution of the quantity of the coating substance applied to the web in the transverse direction thereof. A smoothing member comprises an elongate member extending transversely to the direction of web movement through the apparatus and is flexible with respect to its longitudinal dimension so that the profile of the load distribution in the nip can be adjusted to be relatively steep, i.e, the load in the nip may differ relatively widely at points which are relatively close to each other. An arrangement is provided for selectively variably adjusting the load applied to the smoothing member along its longitudinal dimension.
