Abstract
Apparatus for applying a plurality of color images to cylindrical or frustoconical articles includes a turret mounting radially extending angularly spaced shafts, each of which mounts a mandrel. The turret is fixed vertically and is moved in angular steps so that each of the mandrels is alternately positioned at printing stations and drying stations. The mandrels are rotated in synchronism with printing rolls located at each of the printing stations. Each printing roll is mounted on an individual auxiliary frame which in turn is mounted to a subframe on a horizontal pivot axis so that the printing roll may be adjusted pivotally to a position wherein its outer surface is aligned with the outer surface of a mandrel. The subframe is vertically movable relative to the turret for simultaneously moving all of the printing rolls relative to the mandrels.
