MULTI-PASS LABELLING APPARATUS FOR CURVED OR PLANAR OBJECTS Apparatus for applying labels to the peripheral surfaces or to the end faces of bulky cylindrical objects has a carrier which is transportable up and down as well as toward and away from the labelling station. The carrier supports a suction head which is pivotable about a horizontal axis extending transversely of the direction of movement of the carrier toward and away from the labelling station, and a roll which is rotatable about its own axis a well as pivotable about an axis which is parallel to its own axis and to the pivot axis for the suction head. The latter picks up a horizontal label from a source which is spaced apart from the labelling station, the underside of the label is rendered adhesive while the carrier advances toward the labelling station, the label is then moved into a vertical plane so that its adhesive surface confronts the adjacent surface of the object, and the roll is caused to repeatedly moved along and to bear against the non-adhesive side of the label in order to apply the label to the object at the labelling station. The movements of the suction head and roll about their respective pivot axes can be carried out independently of each other, the same as the movements of the carrier between different levels and toward and away from the labelling station. |
