Abstract
Abstract Method and apparatus for applying labels to articles which are particularly useful for articles which are relatively flimsy and dimensionally unstable, such as plastic carriers for a plurality of filled containers wherein the carrier has a top panel and a skirt extending downwardly therefrom with surface areas on the skirt for receiving labels. In the embodiment shown a series of articles are indexed through a label receiving position. Labels are transferred from a label supply and are pressed against the label receiving surface area on the skirt of the article. The opposite side of the skirt is supported against substantial movement while the label is being pressed against the skirt. An adhesive is applied to the label receiving area on the skirt as the article is being indexed into the label receiving position.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
194 words
Label application apparatus for applying labels to a side wall of an article having relatively thin side walls, comprising: (a) means for automatically successively indexing a series of articles from a supply thereof into position for receiving labels, (b) means for supplying labels to be applied to said articles, (c) means for transferring a label from said label supply means to and pressing it against a side wall of said article, (d) backup platen means movable into position on the other side of and in contact with said article side wall from said label transfer means after the indexing of an article to hold said side wall against substantial movement during the pressing of a label against said side wall, (e) means for moving said backup platen into said side wall support position in response to the indexing of an article into label receiving position and for moving said backup platen out of said side wall support position in response to the completion of label application to said side wall, and (f) means for moving said article out of label receiving position after said backup platen is removed from the side wall support position.
Claim 2
Dependent Claim

Label application apparatus for applying labels to a side wall of an article having relatively thin side walls, comprising: (a) means for automatically successively indexing a series of articles from a supply thereof into position for receiving labels, (b) means for supplying labels to be applied to said articles, (c) means for transferring a label from said label supply means to and pressing it against a side wall of said article, (d) backup platen means movable into position on the other side of and in contact with said article side wall from said label transfer means after the indexing of an article to hold said side wall against substantial movement during the pressing of a label against said side wall, (e) means for moving said backup platen into said side wall support position in response to the indexing of an article into label receiving position and for moving said backup platen out of said side wall support position in response to the completion of label application to said side wall, and (f) means for moving said article out of label receiving position after said backup platen is removed from the side wall support position.
Claim 3
Dependent Claim
72 words
Apparatus as defined in claim 1 which further includes (a) feed chute means for supplying articles to said indexing means, and (b) air assist means for moving said articles along said feed chute means including blower means, duct means for directing a stream of air from said blower means along a wall of said chute means, and ports formed in said chute wall between said duct means and said feed chute means.
Claim 4
Dependent Claim
36 words
Apparatus as defined in claim 2 which further includes vane means associated with said ports for guiding air flow through said ports in the direction of desired movement of said articles along said feed chute means.
Claim 5
Dependent Claim
61 words
Apparatus as defined in claim 1 which further includes (a) feed chute means for supplying articles to said indexing means, and (b) escapement means for controlling the flow of articles from said feed chute means to said indexing means including a plurality of escapement fingers spaced along the path of said articles, each finger having a downwardly depending article stop member.
Claim 6
Dependent Claim
55 words
Apparatus as defined in claim 4 which further includes means responsive to an indexing stroke of said indexing means for raising a first escapement finger means to permit feeding of an article to said indexing means, while lowering a preceding second escapement finger means to prevent other articles in said feed chute means from following.
Claim 7
Dependent Claim
44 words
Apparatus as defined in claim 5 in which said indexing stroke responsive means lowers said first escapement finger means after the feeding of an article and raises said second escapement finger means to permit the advancement of articles remaining on said feed chute means.
Claim 8
Dependent Claim
146 words
Apparatus as defined in claim 1 in which said indexing means includes (a) a linearly reciprocable member movable in a first direction to index articles through said label application apparatus, and movable in a second direction to return to an article indexing position, (b) pawl means carried on said reciprocable member having catch surface means formed thereon for engaging an edge of an article to be indexed, and inclined surface means formed thereon ahead of said catch surface means with a leading edge positioned outside of said engageable edge of articles to be indexed enabling said pawl means to be pushed past and away from an edge of a next article to be indexed during a return stroke of said reciprocal member without engagement of the catch surface means of the pawl means with said next article until said pawl means reaches said article indexing position.
Claim 9
Dependent Claim
88 words
Apparatus as defined in claim 7 which said indexing means further includes rail means disposed on each side of said reciprocable member for supporting articles being indexed, the leading edge of said inclined surface means of said pawl means being located below the upper surface of said rail means to permit movement of said leading edge of said inclined surface means of said pawl means under next articles to be indexed after a return stroke to be initiated without jamming of the pawl means against the next articles.
Claim 10
Dependent Claim
54 words
Apparatus as defined in claim 8 in which said pawl means are pivotably mounted and yieldingly urged upwardly, thereby permitting downward movement of said pawl means on a return stroke below said articles and upward movement to enable retention of the engagement of said catch surface means with an article during an indexing stroke.
Claim 11
Dependent Claim
88 words
Apparatus as defined in claim 1 in which said label transfer means includes (a) transfer plate means supported for reciprocal motion transverse to a side wall of said article, (b) means for connecting a vacuum source to said transfer plate means enabling retention on said transfer plate means of a label received from said label supply means, and (c) means responsive to the indexing of an article into label receiving position for driving said transfer plate means toward and into contact with a side wall of said article.
Claim 12
Dependent Claim
69 words
Apparatus as defined in claim 10 in which (a) said label supplying means includes means for feeding a web having labels thereon to a label transfer position in front of said transfer plate means, and in which (b) said transfer plate means carries web cutting means thereon enabling a label to be cut from said web during a forward stroke of the reciprocal motion of said transfer plate means.
Claim 13
Dependent Claim
31 words
Apparatus as defined in claim 11 which further includes means for holding a label in an upright position while it is being cut from the web by said transfer plate means.
Claim 14
Dependent Claim

Claim 16
Dependent Claim
33 words
Apparatus as defined in claim 14 in which said article retaining means includes yieldingly urging means engaging a surface of an article on the opposite side of said article from said indexing means.
Claim 17
