Abstract: Apparatus for performing a plurality of sequential operations upon each of a series of articles. In the exemplary embodiment, such apparatus is arranged to perform a two stage coating and printing operation on the outer surface of cylindrical tubes. A rotatable turret includes a first and second series of carriers angularly spaced in first and second arrays around the circumference thereof. Means are provided to index the turret to bring the tubes held in the carriers of the first array to a first operational station for coating, and the tubes held in the second array of carriers to a second operational station for printing.
