Abstract: Glue roller for use in labeling machines and the like, comprising a metal hub, a tubelike support body fixed on the hub, and an elastic sleeve with a cylindrical outer surface seated on the support body. The support body is a first moulded part of foam material having sealed boundary zones, which is foamed directly onto the hub. The elastic sleeve is a second moulded part of elastic foam material with sealed boundary zones, which is foamed directly onto the support body. The support body and elastic sleeve are provided with interengaging projections and recesses which extend parallel to the axis of the roller.

Abstract: Apparatus for applying decorative metallic foils to the necks and over the closure elements of bottles. The bottles are orbited past a foid depositing element on a revolving table on which each bottle is supported on a turntable and stabilized by a retractable plunger. The adhesive coated foils are square or rectangular and are deposited so a pair of foil corners project up and down and a pair project laterally. A roller assembly bends in the lateral corners or points as the revolving table revolves. At a transfer area between the revolving table and a bottle removal star wheel a deflector bends down the upwardly projecting foil point. Variously oriented rotating brushes act on the foils when the bottles are on the star wheel and are rotating to finish the foil forming operations.

Abstract: A bottle filling and closing machine and a bottle labeling machine are mounted on opposite sides of a bottle conveyor line close enough together so that both machines can be operated by a single operator. The filling and closing machine, the labeling machine, and the conveyor means extending therebetween are normally driven in synchronism by a common motor. A clutch is included in the drive means for the labeling machine to enable it to be disconnected from the filling and closing machine, and an auxiliary drive motor is coupled to the labeling machine to enable it to be driven independently of the filling and closing machine. The conveyor means extending between the two machines can comprise conveyor star wheels or conveyor worms.

Abstract: A central band of cold glue is applied over most of the length of a label. Each label is then engaged by one of several circumferentially spaced gripper fingers on a rotating head which causes the labels to pass a hot glue applicator which applies bands lengthwise of the label on each side of the central cold glue band. Each label is finally rotated to a properly positioned container where a reciprocable squeezer presses the label onto the container.

Abstract: A bottle filling machine is adapted for circulating cleaning liquid through its combination gas and liquid storage tank and conduits, filler valves and other fluid passageways communicating therewith at high velocity by partitioning the tank into input and output chambers with a float that is urged into sealing relation by buoyancy and by pressure differential developed on its opposed sides as a result of the pressure drop produced in components that communicate between the chambers.

Abstract: Conveying apparatus for upright standing bottles between two synchronously driven bottle treating machines. The apparatus comprises a star wheel and a worm, both being driven synchronously with the bottle treating machines. Supporting and guiding rails for the bottles are provided with gaps through which broken bottles and fragments thereof are discharged.

Abstract: Apparatus for conveying upright standing containers such as bottles includes a driven star wheel which advances the containers in spaced relationship along a curved path. Curved support and guide rails are concentric to the star wheel and are spaced apart a distance to engage the container bottom and top and to restrain the container from being discharged centrifugally from the star wheel path. Abnormal containers such as bottles broken off at their tops or necks will not be confined to the curved path of the star wheel and will be rejected by centrifugal force.

Abstract: Inspection equipment for detection of foreign matter particles in the bottom area of containers with transparent bottoms, such as glass bottles. The equipment has a driven rotor the front face of which lies in the image plane of a projection optic with the illuminated bottle bottom serving as the object plane. The rotor has a first optical element in the form of a radially extending mirror which focuses the incident radiation on a fixed position photoelectric element. The output signal of the photoelectric element feeds an evaluator which responds to a certain decrease of the incident light intensity. The rotor is provided with a second optical element which is responsive to radiation from the center of the container bottom and which signals a second photoelectric cell, which feeds a second evaluator.Both evaluators signal container reject mechanism.

Abstract: A rotary label extracting carrier picks up glue from a glue roller and applies the glue to the back of the frontal label in a label magazine. The label extracting carrier picks up the frontal label with the glue and carries the glued label to a gripper cylinder having gripper fingers which grip the leading edge of glued label and peel it off the label extracting carrier for transfer to a bottle or other object. The circular pitch of the gripper cylinder is smaller than the circular pitch of the label extracting carrier, and the label extracting carrier is rotated synchronously with the gripper cylinder in such manner that the peripheral speed of the label extracting carrier is greater than the peripheral speed of the gripper cylinder. This arrangement produces a smooth peeling action of the labels as they are transferred from the label extracting carrier to the gripper cylinder and thereby substantially eliminates crushing and tearing of the labels.

Abstract: In order to save time and labor when reloading the label magazine of a labeling machine, a relatively large number of labels, such as 3000 to 8000, are piled into a stack, and binding means running along relatively opposite longitudinal sides of the stack and across its opposite end faces are applied to the stack so as to stabilize it. The binding means consists of adhesive tape or of a band of stretchable synthetic material, with or without a low backing trough of cardboard along one side of the stack. The binding means is removed after the unitary label package has been inserted into the magazine of the labeling machine.

Abstract: A label magazine having a bend is provided with ratchet teeth formed on the outside wall of the bend to cause fanning of the labels as they negotiate the bend and thus facilitate movement of the labels around the bend without jamming therein.

Abstract: A label applying turret having label support pads, a label marker and a pressing platen for pressing the label against the marker. The marker is mounted on the turret to rotate therewith and faces outwardly against the inwardly facing side of the label. In one embodiment a label gripping platen is aligned with the marker so that its action in gripping the label to the turret concurrently imposes die marking pressure on the label. In another embodiment a roller platen is mounted externally of the turret and presses the labels against the die marker.This application is a division of copending application Ser. No. 381,184 filed July 20, 1973, now U.S. Pat. No. 3,893,388, which was a continuation of copending application Ser. No. 223,204 filed Feb. 3, 1972, now abandoned.
