Abstract
Abstract A labeling machine with a rotating label turret which picks up labels from a label magazine and carries the labels past a glue applicator roller and to the label application or on-rolling station includes a plurality of radially movable label supports which are radially extendable and retractable at the periphery of the turret. The retractable label supports include vacuum nozzles connectable to a source of suction. In one embodiment of the invention, the label supports are in the form of spaced ring sectors and the label supports retract if they are not carrying a label to provide clearance between the label support and glue applicator roller to prevent deposition of glue on the label supports. In a modified embodiment of the invention, the label supports are in the form of an array of parallel spaced concentric bands or ribs having a radius of curvature approximately equal to the radius of the outer periphery of the turret. The label supports are biased inwardly by springs and provided with rollers which travel along a fixed, centrally located cam surface which controls the radial position of the label supports. A relieved portion in the cam surface causes the label supports to move radially inwardly at the on-rolling station so that the vacuum pickups and the label support bands are flush or recessed with respect to the periphery of the turret so that uniform pressure can be applied to the full width of the labels and the containers.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
191 words
In a labeling machine which includes a rotatable label turret, a label magazine for supplying labels to the turret, and a glue applicator roller located adjacent the periphery of said turret, the improvement comprising a plurality of label supports around the periphery of said turret, means for mounting said label supports on said turret for radial movement with respect to the axis of said turret, means for radially moving said label supports between extended and retracted positions, said means for radially moving said label supports including rollers on each of said label supports, a fixed cam surface and springs biasing said rollers against said cam surface, said cam surface being contoured adjacent said glue applicator roller, and means operable in response to the absence of a label on said label supports to afford inward movement of said label supports to the retracted position to provide clearance between said label supports and said glue applicator roller, and operable in response to the presence of a label on said label supports to lock label supports carrying labels against movement to the retracted position when said label support is adjacent said relieved cam surface.
Claim 2
Dependent Claim
191 words
In a labeling machine which includes a rotatable label turret, a label magazine for supplying labels to the turret, and a glue applicator roller located adjacent the periphery of said turret, the improvement comprising a plurality of label supports around the periphery of said turret, means for mounting said label supports on said turret for radial movement with respect to the axis of said turret, means for radially moving said label supports between extended and retracted positions, said means for radially moving said label supports including rollers on each of said label supports, a fixed cam surface and springs biasing said rollers against said cam surface, said cam surface being contoured adjacent said glue applicator roller, and means operable in response to the absence of a label on said label supports to afford inward movement of said label supports to the retracted position to provide clearance between said label supports and said glue applicator roller, and operable in response to the presence of a label on said label supports to lock label supports carrying labels against movement to the retracted position when said label support is adjacent said relieved cam surface.
Claim 3
Dependent Claim
15 words
The improvement of claim 1 wherein each of said label supports includes a vacuum nozzle.
Claim 4
Dependent Claim
35 words
The improvement of claim 1 wherein said label supports include label support portions in the form of circular ring sectors, said label supports being separated by gaps and together forming the periphery of said turret.
Claim 5
Dependent Claim
128 words
A labeling machine comprising a label turret, a label magazine located adjacent the periphery of said label turret, a glue applicator located adjacent said turret, a label application station, said turret having a peripheral surface with a series of recesses, a corresponding series of label support bands disposed in said recesses, means interconnecting said bands for concurrent movement of said bands between an advanced position in which they extend beyond the peripheral surface of the turret for receiving labels from said label magazine and receiving glue on the labels from said glue applicator and a retracted position at said label appLication station flush with said peripheral surface of said turret in which position the labels are supported at least in part by said peripheral surface of the turret.
Claim 6
Dependent Claim
128 words
A labeling machine comprising a label turret, a label magazine located adjacent the periphery of said label turret, a glue applicator located adjacent said turret, a label application station, said turret having a peripheral surface with a series of recesses, a corresponding series of label support bands disposed in said recesses, means interconnecting said bands for concurrent movement of said bands between an advanced position in which they extend beyond the peripheral surface of the turret for receiving labels from said label magazine and receiving glue on the labels from said glue applicator and a retracted position at said label appLication station flush with said peripheral surface of said turret in which position the labels are supported at least in part by said peripheral surface of the turret.
Claim 7
Dependent Claim
