Abstract
Abstract Apparatus for wrapping bottle necks, preferably with foil wrappers. The apparatus includes wrapper applying mechanism and following treatment apparatus to shape and conform the wrapper to the bottle neck and crown. The treatment apparatus includes a series of pressing and smoothing tools which are arranged on a serpentine path and conveyor means for advancing the bottles on said serpentine path past said tools. The wrapper shaping and conforming tools are desirably arranged on circular arcs and the conveyor desirably comprises star wheels which convey the bottles on said arcs for engagement with said shaping and conforming tools.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
109 words
In apparatus for wrapping bottle necks, which apparatus includes wrapper applying apparatus for applying the wrapper to the bottle neck and following treatment apparatus to shape the wrapper against the bottle neck, the improvement in which said treatment apparatus comprises a series of pressing and smoothing tools arranged on a serpentine path and conveyor means for advancing the bottles on said serpentine path past said tools, said serpentine path comprising a plurality of circular arcs along which said tools are disposed, said conveyor means comprising a plurality of star wheels arranged in series, said star wheels having their axes of rotation substantially at the centers of said circular arcs.
Claim 2
Dependent Claim
109 words
In apparatus for wrapping bottle necks, which apparatus includes wrapper applying apparatus for applying the wrapper to the bottle neck and following treatment apparatus to shape the wrapper against the bottle neck, the improvement in which said treatment apparatus comprises a series of pressing and smoothing tools arranged on a serpentine path and conveyor means for advancing the bottles on said serpentine path past said tools, said serpentine path comprising a plurality of circular arcs along which said tools are disposed, said conveyor means comprising a plurality of star wheels arranged in series, said star wheels having their axes of rotation substantially at the centers of said circular arcs.
Claim 3
Dependent Claim
35 words
The apparatus of claim 1 in which said arcs comprise yieldable friction surfaces against which the star wheels press the bottles to cause the bottles to turn as they are advanced by the star wheels.
Claim 4
Dependent Claim
67 words
The apparatus of claim 2 in which said treatment apparatus further comprises for one of said star wheels a disk-like, pressing-on rotor having a yieldable periphery, means supporting said rotor for rotation within one of the circular arcs, the periphery of said rotor contacting the bottle necks, said rotor being rotated on its axis by rotation of the bottles as they are turned on their own axes.
Claim 5
Dependent Claim
25 words
The apparatus of claim 3 in which the means supporting the rotor has an axis of rotation eccentric to the center of said circular arc.
Claim 6
Dependent Claim
20 words
The apparatus according to claim 3 in which said rotor has a periphery which overhangs the crown of the bottle.
Claim 7
Dependent Claim
102 words
In apparatus for wrapping bottle necks, which apparatus includes wrapper applying apparatus for applying the wrapper to the bottle neck and following treatment apparatus to shape the wrapper against the bottle neck, the improvement in which said treatment apparatus comprises a series of pressing and smoothing tools arranged on a serpentine path and conveyor means for advancing the bottles on said serpentine path past said tools, one of said tools comprising a rotary brush the periphery of which engages the bottle neck, and support means for the brush on which it is arranged concentrically to a circular arc in said serpentine path.
Claim 8
Dependent Claim
102 words
In apparatus for wrapping bottle necks, which apparatus includes wrapper applying apparatus for applying the wrapper to the bottle neck and following treatment apparatus to shape the wrapper against the bottle neck, the improvement in which said treatment apparatus comprises a series of pressing and smoothing tools arranged on a serpentine path and conveyor means for advancing the bottles on said serpentine path past said tools, one of said tools comprising a rotary brush the periphery of which engages the bottle neck, and support means for the brush on which it is arranged concentrically to a circular arc in said serpentine path.
Claim 9
Dependent Claim
99 words
Apparatus for pressing a foil wrapper against a bottle neck and comprising a star wheel, an arcuate rail about the periphery of the star wheel, said rail having a yieldable surface against which the star wheel presses bottles conveyed thereby, whereupon to twirl the bottles on their own axes, a pressing rotor having a turning axis within the arc of said rail and having a peripheral resilient surface disposed for engagement by the necks of said bottles, whereby said rotor presses the wrapper against the bottle necks as the bottles twirl and also turn the rotor on its axis.
Claim 10
Dependent Claim
99 words
Apparatus for pressing a foil wrapper against a bottle neck and comprising a star wheel, an arcuate rail about the periphery of the star wheel, said rail having a yieldable surface against which the star wheel presses bottles conveyed thereby, whereupon to twirl the bottles on their own axes, a pressing rotor having a turning axis within the arc of said rail and having a peripheral resilient surface disposed for engagement by the necks of said bottles, whereby said rotor presses the wrapper against the bottle necks as the bottles twirl and also turn the rotor on its axis.
Claim 11
Dependent Claim
26 words
The apparatus of claim 7 in which the axis of rotation of the pressing rotor is concentric to the axis of rotation of the star wheel.
Claim 12
Dependent Claim
26 words
The apparatus of claim 7 in which the axis of rotation of the pressing rotor is eccentric to the axis of rotation of the star wheel.
Claim 13
Dependent Claim
126 words
In apparatus for wrapping bottle necks, which apparatus includes wrapper applying apparatus for applying the wrapper to the bottle neck and following treatment apparatus to shape the wrapper against the bottle neck, tHe improvement in which said treatment apparatus comprises a star wheel, a yieldable friction surface disposed in an arc about the star wheel whereby the star wheel advances the bottle along said arc and presses the bottle against said yieldable friction surface to cause the bottles to turn about their own axes as they are advanced by the star wheel, and pressing and smoothing apparatus disposed on an arc adjacent the bottle neck to press the wrapper against the bottle necks as the bottles turn on their own axes and advance along said arc.
Claim 14
Dependent Claim
126 words
In apparatus for wrapping bottle necks, which apparatus includes wrapper applying apparatus for applying the wrapper to the bottle neck and following treatment apparatus to shape the wrapper against the bottle neck, tHe improvement in which said treatment apparatus comprises a star wheel, a yieldable friction surface disposed in an arc about the star wheel whereby the star wheel advances the bottle along said arc and presses the bottle against said yieldable friction surface to cause the bottles to turn about their own axes as they are advanced by the star wheel, and pressing and smoothing apparatus disposed on an arc adjacent the bottle neck to press the wrapper against the bottle necks as the bottles turn on their own axes and advance along said arc.
Claim 15
Dependent Claim
40 words
The apparatus of claim 10 in combination with a pressing rotor within said arc and on which said pressing and smoothing apparatus is mounted for pressing the wrapper against the bottle necks as the bottles turn on their own axes.
