In a labeling station for applying labels onto objects, having at least one pickup element mounted eccentrically on a rotatable carrier for movement about an axis, a gripper cylinder comprising a rotating carrier having eccentrically disposed gripping and pressing elements thereon, which elements are tangent to the circulation path of the pickup elements approximately in synchronism, the labels being transferred by the gripping and pressing elements to objects moved along a transport path, the part of the gripper cylinder which carries the pressing elements being eccentrically mounted on the gripper-cylinder shaft in such a way that the areas to be labeled of the objects are tangent to or slightly intersected by the path of rotation of the pressing elements, and the part carrying the pressing elements and the part carrying the gripping elements rotate with the same angular velocity, the improvement comprising means for adapting the rotative speed of the pressing elements to the path speed of the areas to be labeled of a first group of objects being conveyed along an arcuate path whose areas to be labeled are, in relation to the areas to be labeled of another group of objects being conveyed along an arcuate path, at a different distance from the gripper-cylinder axis including means for releasably replacing the part carrying the pressing elements with another part of a different diameter carrying pressing elements. |
