APPARATUS FOR TRANSPORTING CONTAINERS IN LABELLING MACHINES

摘要

Apparatus for transporting containers having circular portions with any one of a number of different diameters first along an adhesive applying unit and thereupon past one or more units which apply labels all the way around the circular portions of the containers has a rotary turntable with a set of depending rotary supporting elements for discrete containers. The supporting elements are rotated about their own axes, while orbiting about the axis of rotation of the turntable, by two arcuate cams which are adjacent the path of orbital movement of the supporting elements and are tracked by roller followers provided on disc-shaped holders at the upper ends of the supporting elements. Adjustment of the apparatus for the transport of containers having circular portions of different diameters is effected by moving the cams in the circumferential direction of the turntable. The positions of the various treating units remain unchanged.
