ABSTRACT:
An improved elongated coating rod holder for a coating doctor apparatus wherein the rod holder has formed therein an elongated cavity for receiving the coating rod with the cavity comprising at least two sealing surfaces therein. The coating rod holder also has formed therein a cooling water chamber formed as a plurality of smaller chambers having an interconnecting passageway between adjacent chambers. The cooling water chamber is formed directly below the elongated cavity which is connected to at least one cooling water inlet and at least one cooling water outlet formed in the rod holder. The elongated cavity and the cooling water chamber are formed in-line with the axis of rotation of the coating rod so that a pressure exerted on the coating rod during a coating operation will be transmitted downwardly through the coating rod and outwardly to act to seal the rod member against the sealing surfaces of the elongated cavity thereby preventing leakage of water from the water chamber to the exterior of the rod holder.
