The invention relates to a holder for a cradle of a coating bar or for a coating blade in a coating unit and a method for securing the cradle of the coating bar or the coating blade in a coating device. The coating bar or blade are arranged to spread and smooth a size film or a corresponding layer of coating agent onto a face of a moving base to be coated by loading the coating bar or blade against the moving base. The moving base may be a roll of a size press or the web passed over a back-up roll. The cradle of the coating bar or the coating blade is mounted in a holder arranged in an application beam transverse to the machine direction. A journalling duct transverse to the machine direction is formed in the frame of the holder. An oblong member is arranged rotatably in the journalling duct and comprises a cam-like projection of eccentric section. The member can be rotated for the purpose of fixing the cradle of the coating bar or the coating blade in its place. In this position, the cam-like projection rests against a rear face of the cradle of the coating bar or of the coating blade and secures the cradle or coating blade against a support provided on the application beam.
