Abstract: An apparatus for imprinting a code or other marking on articles, such as capped jars, which comprises a printing or coding wheel having a series of circumferentially spaced printing die elements and rotatably mounted at a printing station above a straight line conveyor on which capped jars or other articles, are advanced, the wheel being disposed at an elevation to bring the die elements into engagement with the tops of jars advanced to the station and a drive for the wheel which includes a differential gear system for accelerating or decelerating the printing wheel and a stepping motor which is responsive to sensors spaced along the path of advance of the jars as they approach the printing station and operating to sense the location of the jar tops relative to the printing station. The sensors are connected through electric circuitry with a control device including a timer whereby the rotation of the printing wheel is adjusted so that the die elements match the spacing of the advancing jar tops and a die element is engaged with each successive jar top to print a code thereon.
