Abstract: My invention relates to the method and apparatus for printing stripe patterns on the outside surface of cylindrical objects such as glass tumblers with their axes vertical during the printing operation, the stripes being printed substantially circularly about the axis of the cylinder as the center. The cylinder being striped is supported at a printing station for free rotation about its vertical axis. A stripe printing head provided with a stripe printing roller and an ink applicator drum, both rotating about substantially vertical axes, is moved to bring the printing roller in tangential printing contact with the tumbler surface. The printing head includes an enclosed ink (or pigment) supply well adjacent a segment of the perimeter of the applicator drum and means for maintaining the supply well full from a supply reservoir.
