Abstract
Apparatus for decorating cylindrical articles includes a plurality of mandrel assemblies mounted on a carrier that rotates continuously on a main axis. The assemblies are equally spaced from each other and are disposed in an array surrounding the main axis. A cam device drives the base for limited radial movements relative to the carrier. Each assembly includes a base and a cantilevered mandrel pivotally mounted to the base on a mandrel pivot that is parallel to the main axis. For each revolution of the carrier a decorator engages an article on the mandrel and applies a decoration to such article. Engagement between the articles and decorator produces a reaction force that tends to tile the free end of the mandrel radially inward about the cam means as a center, if the reaction force is permitted to do so, decorating quality will be degraded. A bracing device is provided to resist tilting of the mandrel. On form of such bracing device includes a track and a roller that is mounted on the base and rides on the track. The tracks are fixedly mounted on the carrier and are disposed generally in a common plane at right angles to the main axis.
