<p>Marking apparatus for applying indicia to capped bottles or other containers of varying heights. The device consists of a rim having a print ring on the outer perpheral surface held in frictional engagement with a drive wheel that also performs a function of supplying ink to the print ring and is maintained in frictional engagement through a smaller diameter wheel engaging the inner surface of the rim. A substantial point contact between the inner surface of the rim and the outer surface of the support wheel allows the rim to move vertically to compensate for bottles of varying heights passing under the rim. While not necessary to the practice of the invention, an idler roller may engage the inner surface of the rim at the location spaced from the contact with the second wheel to provide additional support for the rim during its normal rotational movement.</p> |
