Abstract
Abstract In equipment that is intended for applying a blank of foil to bottles and that includes a turntable, at least one labeling station, a rotating transport star that has accommodations for the bottles and is positioned downstream of the turntable, and a rotating transfer-and-application device consisting of several similar units distributed around its circumference with elements that fold and press down the ends of the blank extending beyond the head of each bottle, the pressure-application elements and if necessary the folding elements are, as they revolve, kept outside the circumference of the elements on the turntable that accommodate the bottle. This avoids collisions at this point. The axis of rotation of the pressure-application elements and the axis of rotation of the output star are accordingly mutually eccentric in such a way that the orbits of the accommodations and of the pressure-application elements coincide along one segment. The equipment will not malfunction and will ensure satisfactory bottle foiling.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
178 words
In an apparatus for applying a blank of foil to bottles and that includes a turntable with a plurality of separately controlled devices around its circumference for rotating the bottles, at least one labeling station for transferring the foil blanks to the bottles once the rotation devices have positioned the bottles at a specific angle, an application device that presses the blanks onto the bottles, a rotating output transport star that has accommodations for the bottles and is positioned downstream of the turntable and upstream of a conveyor belt that carries the bottles away, and a supporting stand that is positioned in the vicinity of the output transport star and has a rotating transfer-and-application device comprising a plurality of similar units distributed around its circumference with pressure-application elements that fold and press down the ends of the blank extending beyond the head of each bottle, the improvement which comprises positioning the pressure-application elements so that as they revolve they are kept outside the circumference of the circle defined by the devices on the turntable that accommodate the bottles.
Claim 2
Dependent Claim
178 words
In an apparatus for applying a blank of foil to bottles and that includes a turntable with a plurality of separately controlled devices around its circumference for rotating the bottles, at least one labeling station for transferring the foil blanks to the bottles once the rotation devices have positioned the bottles at a specific angle, an application device that presses the blanks onto the bottles, a rotating output transport star that has accommodations for the bottles and is positioned downstream of the turntable and upstream of a conveyor belt that carries the bottles away, and a supporting stand that is positioned in the vicinity of the output transport star and has a rotating transfer-and-application device comprising a plurality of similar units distributed around its circumference with pressure-application elements that fold and press down the ends of the blank extending beyond the head of each bottle, the improvement which comprises positioning the pressure-application elements so that as they revolve they are kept outside the circumference of the circle defined by the devices on the turntable that accommodate the bottles.
Claim 3
Dependent Claim
28 words
An apparatus according to claim 1, wherein the axis of rotation of the pressure-application elements and the axis of rotation of the output transport star are mutually eccentric.
Claim 4
Dependent Claim
78 words
An apparatus according to claim 1, wherein the amount of eccentricity between the axis of rotation of the output transport star and the axis of rotation of the pressure-application elements and the radial distances of the accommodations in the output transport star from their axis of rotation and of the pressure-application elements from their axis of rotation are such as to ensure that the orbits of the accommodations and of the pressure-application elements extensively coincide along one segment.
Claim 5
Dependent Claim
57 words
An apparatus according to claim 3, wherein the one segment of the orbits is located in the vicinity of the conveyor belt that carries the bottles away, whereby since the interval between adjacent pocket-shaped accommodations in the output transport star and between adjacent pressure-application elements is always identical, peripheral speeds will always be identical within the segment.
Claim 6
Dependent Claim
24 words
An apparatus according to claim 1, wherein the number of pressure-application elements is lower than that of the accommodations in the output transport star.
Claim 7
Dependent Claim
29 words
An apparatus according to claim 1, including a mechanism that drives the pressure-application elements and a mechanism that drives the output transport star, the two drive mechanisms being separate.
Claim 8
Dependent Claim
24 words
An apparatus according to claim 6, wherein the mechanism that drives the presure-application elements is a reversing gear train alongside the output transport star.
Claim 9
Dependent Claim
40 words
An apparatus according to claim 7, wherein the reversing gear train has a driveshaft that extends through a housing flange on the supporting stand and mutually meshing cogwheels mounted on a supporting plate that extends over the output transport star.
Claim 10
Dependent Claim
22 words
An apparatus according to claim 8, wherein the housing flange has a level adjustor to control the height of the supporting stand.
Claim 11
Dependent Claim
56 words
An apparatus according to claim 8, wherein a bearing housing is mounted concentric to the axis of rotation of the transfer and application device on the side of the supporting plate that faces away from the cogwheels, the bearing housing accommodating a bearing shaft that secures a retainer plate on which the pressure-application elements are mounted.
Claim 12
Dependent Claim
63 words
An apparatus according to claim 10, wherein the pressure-application elements are mounted on the side of the retainer plate that faces the output transport star, the apparatus further including sleeves mounted on the side of the retainer plate that faces the supporting plate, and spring-loaded drag rods for the pressure-application elements arranged so as to be slidable up and down inside the sleeves.
Claim 13
Dependent Claim
21 words
An apparatus according to claim 11, wherein the axes of the drag rods coincide with the axes of the pressure-application elements.
Claim 14
Dependent Claim
43 words
An apparatus according to claim 11, further including support rollers mounted in the sleeves, the support rollers projecting out laterally and operating in conjunction with a contour on a pot-shaped wall of the bearing housing in order to move the pressure-application elements vertically.
Claim 15
Dependent Claim
40 words
An apparatus according to claim 10, including folding elements having preliminary-folding components, the preliminary-folding components being positioned radially around a common shaft that meshes through a cogwheel with the cogwheel in the reversing gear train that drives the bearing shaft.
Claim 16
Dependent Claim
18 words
An apparatus according to claim 14, wherein the folding elements are pivoting arms guided by a contour system.
Claim 17
Dependent Claim
34 words
An apparatus according to claim 15, wherein the contour system is designed in such a way that the pivoting arms, which are equipped with a nose, also function as preliminary and final folding mechanisms.
Claim 18
Dependent Claim
23 words
An apparatus according to claim 16, wherein the pivoting arms are guided by a contour on a guide plate in the bearing housing.
Claim 19
Dependent Claim
41 words
An apparatus according to claim 17, wherein the pivots of the pivoting arms are on a circle that is concentric with the orbit of the pressure-application elements and the number of pivoting arms is greater than the number of pressure-application elements.
Claim 20
Dependent Claim
24 words
An apparatus according to claim 15, wherein the contoured guide for the pivoting arms is independent of the system that guides the pressure-application elements.
Claim 21
Dependent Claim
30 words
An apparatus according to claim 19, wherein the pivots of the pivoting arms are on a circle that is concentric with that of the accommodations in the output transport star.
Claim 22
Dependent Claim
14 words
An apparatus according to claim 1, wherein the pressure-application elements are also folding elements.
Claim 23
Dependent Claim
10 words
An apparatus according to claim 1, further including folding elements.
