Abstract
A rigid metal housing is positioned downstream of a coating applicator. The housing supports a plurality of positionable contact elements formed of a low friction, high wear-resistant material, which extend inwardly from the housing to engage a slow speed rotating rod. At least one of the contact elements is adjustable to support the rod for stable rotation, and to retain an effective seal between the contact elements and the rod to thereby prevent leakage of clearing/lubricating fluid into the applied coating. The contact elements may be advanced inwardly as the elements and the rod wear, thereby extending the effective life of the rod holder apparatus. Screws may bear against a rear contact element through segmented backing plates allowing refinement of the coat weight along the width of the substrate. Furthermore, an air tube may be positioned between the housing and a rear fixture to adjust overall coating thickness.
