Abstract: In a labeling station for applying labels one above the other onto objects, having at least one pickup element mounted eccentrically on a rotating carrier for movement about an axis, a gripper cylinder is provided having a rotating carrier having eccentrically disposed gripping and pressing element for the upper and lower labels, which elements are tangent to the circulation path of the pickup elements approximately in synchronism. The labels are transferred by the gripping and pressing elements to objects moved along a transport path, whose areas to be labeled are at different distances from the gripper cylinder axis.

Abstract: A labeling machine is provided to apply simultaneously two labels to different diameter portions of a bottle, e.g. the neck and belly. The structure for applying the belly label is conventional but above the usual affixing element there is provided a second affixing element which is operatively connected to a cam follower which senses a cam track opposite the labeling station. This causes the second affixing member to be projected radially outward at the time of label affixing so it reaches the narrow diameter portion of the bottle.

Abstract: A labeling station of a labeling machine for bottles or the like having a gripping cylinder rotatable in one direction. The station includes a rotatable carrier and at least one glue segment mounted on the carrier for oscillatory rotational movement about an axis of rotation disposed between the center of curvature of its cylindrically curved pickup surface and the pick up surface, to dispose the center of the pickup surface tangential to the gripping cylinder at the center of the oscillatory movement. The rotational movement of the gluing segment is accelerated and retarded to effect rolling of the pickup surface on the gripping cylinder, by rotating the carrier and gripping cylinder in the same direction and rotating the gluing segment in the opposite direction during the rolling contact.

Abstract: A bottle labeling machine is provided with a circular rotatable support about which there are positioned a gluing station, a magazine carrying a stack of labels and a gripper cylinder so that the pickup-transfer surface of a segment carried by said support successively receives glue, picks up a label and transfers it to the gripper cylinder. The segment is geared so that while carried by said support it rotates about its own axis in opposite direction from the support and from the gripper cylinder. This permits a particular machine capacity to be realized with fewer gluing segments.
