<p>A turntable in a bottle-processing machine, more particularly a labelling machine, has a plurality of sensor-controlled rotating plates arranged in a circle, and a flat, stationary control-cam. The cam is scanned as the turntable rotates by the rotating-plate sensors each sensor pivoting a rotating plate back and forth by means of a lever-arm guided trailingly in the control-cam. A gearwheel connected to the lever-arm is arranged between and meshes with gearwheels of two adjacent rotating plates. The two rotating plates controlled in rotation by the same gearwheel, are mounted, together with the gearwheel and its lever-arm, in a common cup-shaped housing-block. The turntable has sockets in which the housingblock may be secured, in a predetermined rotational position, by means of stops, catches, or the like.</p> |
