ABSTRACT A labelling station in a labelling machine, more particularly for bottles, has one or more glueing segments mounted upon a carrier driven in rotation. The axes of rotation of the segments are arranged, upon the carrier, between the centres of curvature of their pick-up surfaces (which are curved cylindrically with a radius shorter than the distance between the axis of the carrier and the gripper cylinder) and the pick-up surfaces, and move in a circular path concentric with the axis of the carrier. The carrier, gripper cylinder, and glueing segments are coupled together, by a step-up and a non- uniform transmission, in such a manner that they rotate in the same direction. The said glueing segments carry out an accelerated or a retarded rotary motion in the opposite direction in such a manner that their pick-up surfaces roll off upon the glueing roller, the labels, and the gripper cylinder. The labelling station is designed for selective operation with one or more glueing segments, and the step-up and non-uniform transmissions are exchangeable in such a manner that the step-up ratio of the transmission between the carrier and the gripper cylinder is inverse to the number of glueing segments on the carrier and of the divisions of the gripper cylinder. The non-uniform transmission is in the form of a hypocyclic drive, each rotary wheel of which is rigidly coupled to the drive-shaft of the removal element and comprises drive-pins, while the stationary ring-gear comprises teeth with flanks varying in steepness according to the acceleration or retardation of rotation required for the rolling motion of the glueing segments at individual stations. At least that section of the ring-gear which operates in the vicinity of the gripper cylinder, is exchange- able.
