ABSTRACT:
A simple, double rotary workpiece or cage holder is disclosed for coating articles such as tubes or article-holders. The articles or article holders are supported in oversized support holes or on undersized pegs so that rotation of the cage about a horizontal axis causes gravity-induced precession of the tubes. The center of gravity of the article holders may be displaced so that the article holders are maintained at an acute angle relative to the cage axis, to facilitate coating difficult shapes such as lenses.
