Machine for labeling containers around their complete circumference

In a machine for labeling containers completely around their circumference, having a driven rotating turntable with rotating plates that are positioned around the circumference of the turntable and accommodate the containers, and drive means for rotating the plates at different individual speeds as the plates travel past a labeling station, including roller cams and a recessed cam defining a cam path for adapting to the cross-sections of different containers, the improvement wherein:

• one section of the recessed cam comprises yieldable cam elements each comprising spaced apart spring steel leaf springs that are positioned at intervals along the cam path, wherein the leaf springs have mutually facing inner surfaces supported by spacing rollers and mutually remote outer surfaces supported by supporting elements and wherein the spacing rollers have a diameter that equals the distance between the leaf springs and means for retaining the spacing rollers between the leaf springs to prevent the spacing rollers from being lifted out of the cam path, and adjustable means for supporting the cam elements.
