Abstract
Abstract Apparatus for coating with a desired substance a succession of beverage bottles traveling along an arcuate guideway. A star wheel assembly, rotatable about an axis at which the arcuate guideway is centered, feeds the successive bottles along the guideway, further coacting with the opposed guideway-defining surface to cause rotation of each bottle about its own axis. Coaxially mounted on the star wheel assembly, either for simultaneous rotation therewith or for independent rotation, one or more annular rows of discrete coating bodies or one or more coating rolls apply the coating substance to the successive bottles, creating one or more band-shaped coatings around each bottle. In one embodiment the star wheel assembly is replaced by a feed roll assembly comprising a pair of annular rows of independently rotatable feed rolls.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
222 words
Apparatus for coating a succession of substantially cylindrical or round articles such as bottles with a desired coating substance, comprising, in combination: (a) Guide means defining an arcuate guideway for the passage of successive articles to be coated, said arcuate guideway being centered at a predetermined axis and said guide means having an arcuate guide surface made of a material capable of offering a high frictional resistance to each article to be coated; (b) feed means comprising at least one star wheel for feeding the successive articles along the arcuate guideway while pressing the articles against the guide surface of the guide means itself, said star wheel having teeth each of which has at least a concave leading side having a smoothly finished surface for sliding contact with the article with a little frictional resistance, whereby said star wheel is adapted to permit rotations of each article about its own axis in sliding contact with the star wheel and in frictional contact with the guide surface of the guide means; (c) coating means rotatable about a predetermined axis and adapted to be pressed against the successive articles being fed along the arcuate guideway for application of a desired coating substance thereto; and (d) whereby at least one band-shaped film of the coating substance is created around each article by the coating means.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
21 words
The coating apparatus according to claim 1, wherein the coating means is mounted on the feed means for simultaneous rotation therewith.
Claim 4
Dependent Claim
31 words
The coating apparatus according to claim 1 or 2, wherein the coating means comprises at least one series of discrete coating bodies arranged at constant angular spacings about the predetermined axis.
Claim 5
Dependent Claim
29 words
The coating apparatus according to claim 3, further comprising means for biasing each coating body into relative sliding contact with one of the articles traveling along the arcuate guideway.
Claim 6
Dependent Claim
26 words
The coating apparatus according to claim 1 or 3, further comprising means for adjustably moving the coating means in the axial direction of the feed means.
Claim 7
Dependent Claim
19 words
The coating apparatus according to claim 1 or 3, wherein the coating means comprises at least one coating roll.
Claim 8
Dependent Claim
84 words
The coating apparatus according to claim 1 or 2, further comprising means for supplying the coating substance to the coating means, the supplying means comprising: (a) a supply roll rotatable about an axis parallel to the predetermined axis; (b) means for delivering the coating substance to the supply roll at a controlled rate; and (c) a transfer roll rotatable in contact with the supply roll and with the coating means for passing the coating substance from the supply roll on to the coating means.
Claim 9
Dependent Claim
66 words
The coating apparatus to claim 1 or 2, further comprising means for supplying the coating substance to the coating means, the supplying means comprising: (a) a container for containing a supply of the coating substance, the container being mounted on the feed means for simultaneous rotation therewith; and (b) means for delivering the coating substance from the container to the coating means at a controlled rate.
Claim 10
Dependent Claim
43 words
The coating apparatus according to claim 1, wherein the coating means is coaxially mounted on the feed means for rotation relative to same, and wherein the apparatus further comprises means for rotating the coating means at a different speed from the feed means.
Claim 11
Dependent Claim
44 words
The coating apparatus according to claim 9, wherein the apparatus includes a roll in rolling contact with the coating means for supplying the coating substance thereto, and wherein the rotating means comprises means for imparting the rotation of the feed means to the roll.
Claim 12
Dependent Claim
25 words
The coating apparatus according to claim 9, wherein the rotating means comprises a planetary gear train connected between the feed means and the coating means.
Claim 13
Dependent Claim
66 words
The coating apparatus according to claim 1, further comprising a dispenser for supplying the coating to the coating means, the dispenser comprising: (a) a fixed housing (b) a dispenser element slidably mounted within the housing for movement toward and away from the coating means and partly projecting outwardly therefrom for dispensing the coating substance; and (c) means for biasing the dispenser element toward the coating means.
Claim 14
Dependent Claim
45 words
The coating apparatus according to claim 12, further comprising a transfer roll rotatably mounted between the dispenser and the coating means for passing the coating substance from the former to the latter, the dispenser element being biased into relative sliding contact with the transfer roll.
