In a labeling machine having a labeling station including a support means for revolving the support about its axis successively past a gluing roller, a label pickup station and a label gripping cylinder, at least one gluing segment on the support axis, the gluing segment having a cylindrically curved pickup surface with a radius smaller than the distance between the support axis and the gripping cylinder, the gripper cylinder and each gluing segment being coupled to one another through a nonuniformity gearing such that they have the same sense of rotation and each gluing segment performing a rotatory movement in the opposite direction which is accelerated or retarded such that its pickup surface rolls against the glue roller, the labels and the gripper cylinder, the labeling station being designed for optional operation with one or more gluing segments and the nonuniformity gearing being replaceable such that the transmission ratio of the gearing from the support to the gripper cylinder is reciprocal to the number of gluing segments with which the support is provided and the division of the gripper cylinder, the improvement wherein the nonuniformity gearing comprises a stationary sun gear and a lantern-pinion gearing, each lantern pinion being fixedly coupled with the drive shaft of each gluing segment and being provided with trundles, the sun gear having teeth with the flanks of different steepness according to the acceleration or retardation of each gluing segment, at least the section of the sun gear which acts in the area of the gripper cylinder being interchangeable. |
