Abstract
An apparatus is disclosed which transports and rectifies objects, such as pharmaceutical capsules, and prints appropriate indicia on the objects. The apparatus comprises a two-drum system, the first drum being used to shift objects from a radial to a longitudinal position, and then to reorient some of the capsules so that, when the capsules are delivered to a second drum, the cam drum, all capsules are pointing in the same direction. The system takes advantage of gravity for rectification. Spin printing means are provided to print indicia on the rectified objects, as the objects travel along the periphery of the cam drum. A process for operating the apparatus is disclosed.
