Abstract
In a labeling machine for a can or bottle, a label on a vacuum drum is wiped on the reverse face near one edge with a solvent and also is sprayed on the reverse face near the other edge with an adhesive, the label then being wrapped around and affixed to the can or bottle to expose the obverse face of the label. Mechanism for accomplishing these actions and for synchronizing adhesive spraying and wrapping speed is disclosed.
Claims14
An apparatus for applying a label to a container, comprising:
- (a) a frame;
- (b) a vacuum drum mounted for continuous rotation on said frame, said vacuum drum having at least one axially extending, radially raised portion on its outer periphery;
- (c) container conveying means mounted on said frame for spacing and then tangentially presenting individual containers to an adjacent periphery of said vacuum drum;
- (d) means for supplying a label to said outer periphery of said vacuum drum, said label having an obverse side and a reverse side and a leading edge and a trailing edge , said label being positioned on said drum with said reverse side exposed and said trailing edge upon said raised portion of said drum;
- (e) means on said frame for wiping solvent onto the raised and exposed trailing edge of said label in advance of rotation of said label to said adjacent periphery of said drum, said solvent wiping means being outwardly spaced from said outer periphery a sufficient distance so that said wiping means comes into contact solely with said raised trailing edge of said label;
- and,
- (f) means on said frame for ejecting adhesive onto the exposed leading edge of said label in advance of rotation of said label to said adjacent periphery of said drum, for tangential adhesive engagement with a container, said adhesive ejecting means being outwardly spaced from said outer periphery a sufficient distance to prevent contact between said ejecting means and said raised portion of said drum.

A method of applying a label to a circular cylindrical body of a container comprising the steps of:
- a. disposing the obverse side of a label about the periphery of a continuously rotating cylindrical drum, having at least one axially extending, radially raised portion to displace the trailing edge of the reverse side of said label outwardly;
- b. ejecting an adhesive only onto the leading edge of said label, from a location removed radially outwardly from said raised portion;
- c. wipe-applying a solvent only onto the trailing edge of said label, as it comes into contact with a solvent applicator spaced slightly from said periphery of said drum;
- d. continuously conveying containers in spaced relation, and tangentially presenting individual containers to an adjacent periphery of said vacuum drum for contacting said leading edge of an individual label;
- e. rotating said container and said attached label between said drum and an opposing curved roll on pad.
