A labelling machine which includes a plurality of label suction drums rotatably mounted on a bed plate and a plurality of label holders for supplying labels one-by-one to a corresponding label suction drum. A label applicator drum is positioned adjacent to the label suction drums for receiving labels carried by the label suction drums, and thereafter applying the labels to an object which may have either an arcuate or a planar surface. Each label suction drum is provided with a plurality of arcuately spaced projections and vacuum suction outlets between the projections. The labels are retained on a peripheral surface of each label suction drum between the projections by a vacuum applied through the vacuum suction outlets. An upper stop element is positioned adjacent the periphery of each label suction drum and the label applicator drum. The upper stop element, which is spaced from the bedplate by a distance corresponding to the height of the labels, corrects any horizontal misalignment of the labels relative to the label suction drum. A push mechanism urges the labels carried by the label suction drums towards the label applicator drum. |
