Abstract: Mounting and drive coupling for the extracting element support of a labelling station for a labelling machine. The mounting of the table which supports the extracting elements is positioned exclusively on the outer edge of the table, while the coupling between the table and the central drive shaft is located in the central space between the transmission and drive mechanisms and above the transmission elements. An alignment marking disc and marking wheel are included to assist in relatively positioning the extracting element with the support shaft.

Abstract: Wrap-around labels are applied with a hot-melt adhesive in a labelling machine in which upstream of the label box, the containers have the glue or adhesive applied to them by at least one, and preferably two, alternately operable nozzles while the rotary plates on which the containers are mounted are temporarily held stationary. This provides for highly precise gluing and the containers can then be rotated counter to the direction of rotation of the turntable carrying the plates at the label box so that a precise removal of the wrap-around label from the box is effected without allowing glue to accumulate on other labels in the box and impairing the labelling operation.

Abstract: A container labeling machine for applying one or the other of normal length body labels or extra-length boy labels has a rotating rotary table with container supporting controllable rotary plates. Adjacent its periphery is arranged a first labeling station for applying the normal length labels with a rotating labeling cylinder and a second labeling station for the extra-length labels with a stationary label container contacting the path of rotation of the containers. Two independent drives are provided for rotating the plates, one of which regulates the positioning and/or rotation of the rotary plates in the area of the first labeling station, and the second for continuous rotation of the rotary plates in the area of the second labeling station. The rotary plates are selectively connectible with the first or second drive. The two labeling stations and their common brush-on station overlap one another, whereby a very short total treatment stretch is possible.

Abstract: A device for the application of labels onto the periphery of cylindrical containers, which are advanced at intervals from each other, comprises a continually rotating drum which carries a stationary gripping member and a movable gripping member, which receive cold glue from a glue supply device and grip the uppermost label from the stack of labels to transmit this label to one of the advanced containers. The movable gripping member is movable under the control of a cam arrangement toward the front end of the label being transmitted and carries that front end therealong whereas the stationary gripping member while passing the rear end of the label applies glue to that rear end.

Abstract: A labeling machine has a rotor on which several oscillatingly driven pallet shafts are supported. Each shaft has a carriage shiftable transversely to the shaft axis. Glue pallets having partly cylindrical surfaces for being coated with glue are mounted to the carriage and are thereby movable from a radially outward position to a radially inward or neutral position for, respectively, contacting a glue roller and a label in a stack successively and for being retracted to neutral position out of the path of the roller and stack. The shafts have an enlarged central section which is rectangular in cross section and a complementarily shaped channel on a sleeve that carries the curved pallets is supported for sliding transversely to the pallet shaft axis.

Abstract: An improvement in a labeling station for bottles having pivoting extractors 2, 3, 4 with convex pickup surfaces, means for applying adhesive to the extractors and means for rolling the extractors over a stack of labels so as to pick up the front-most label which is thereafter supplied to a gripping cylinder, all in conventional manner. In accordance with the invention the labels are present as stacks in a magazine which can be moved from operative to inoperative position by holders which are activated only in the intervals between label removals so that the magazine can be moved to inoperative position when there is a gap in the supply of bottles going through the station.

Abstract: A bottle labeling machine has a turret rotating on a fixed axle. The turret has circumferentially spaced apart curved glue pallets mounted on individual pallet shafts supported in oscillatable drive members, respectively, which drive the shafts. The pallets orbit and oscillate to pick up glue from a roller, pick up a label next and deposit the label on a cylinder from which it is transferred eventually to a bottle. The drive members are externally splined axially and are each surrounded by an internally axially splined clutch member. The drive member has a smooth bore to permit it to rotate on a shaft that is driven in oscillating fashion as the turret rotates. The oscillating shaft has a transversely extending element on which there are axially projecting teeth that engage in corresponding recesses in the clutch member to effect oscillation of the pallet shaft.

Abstract: Labeling machine comprising a turret carrying plural pallets for periodically picking up glue, picking up a label on the glue, and transferring the glued label to a bottle or other workpiece by rotating the turret and oscillating the pallets radially inward and outward. Each pallet has a double-acting dog clutch for engaging or disengaging the drive which oscillates it; the clutch can be shifted only when the turret is at a particular angular position at which the pallet is sufficiently radially retracted to be clear of the sources of glue and labels and the mechanism for transferring labels. When a bottle is presented for receiving a label from a particular pallet the clutch is shifted to or maintained at its position for engaging the oscillating drive so the pallet transfers a glued label for application to the bottle.

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.

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.
