This invention relates to a labeling system for continuously applying a layer of a UV curable adhesive to plastic, sheet fed, cut and stack, labels, irradiating the adhesive on the labels to render the adhesive sufficiently tacky to effectively adhere the labels to containers in a commercial labeling machine and thereafter applying the labels to discrete containers through the sufficiently tacky adhesive layer. The plastic labels can be clear, opaque (including metallized) plastic films and can be retained in a dispensing magazine prior to the application of the UV curable adhesive to the labels.

1. An apparatus for continuously applying plastic labels to containers, said apparatus including:a rotatable applicator roll for receiving a UV curable adhesive on the outer surface thereof; a rotating transfer member including a plurality of transfer pads carried thereon, said transfer member being located to rotate the transfer pads in close proximity to the outer surface of the applicator roll, whereby adhesive from the roll is transferred to an outer surface of each of said pads; a dispensing magazine for retaining a plurality of individual labels in a stack, with the lowermost label in the stack being located in a downstream path of travel of the transfer pads after each of said transfer pads has engaged the outer surface of the applicator roll to receive adhesive thereon, each of said pads, with the adhesive thereon, being rotated into close proximity with the lower surface of the lowermost label in the magazine for selectively applying the adhesive to the lowermost label in the stack and for removing said lowermost label from the stack through surface adhesion to releasably secure said lowermost label to each of said transfer pads; a UV cure station adjacent the transfer member downstream of said dispensing magazine, said UV cure station including a rotatable member for receiving the individual labels with the adhesive thereon from the transfer pads, and directing the labels through a UV cure section to thereby partially cure the adhesive to increase the tackiness of said adhesive; a container handling device for receiving containers at an inlet; rotating said containers through a label application section, and directing the containers with the labels applied thereon to an outlet; said UV cure station being positioned adjacent to the container handling device such that the individual labels with the partially cured adhesive thereon are directed sequentially into engagement with the periphery of discrete containers as the discrete containers are directed through the label application section. 2. An apparatus for continuously applying plastic labels to containers, said apparatus including:a rotatable applicator roll for receiving a radiation curable adhesive on the outer surface thereof; a rotating transfer member including a plurality of transfer pads carried thereon, said transfer member being located to rotate the transfer pads in close proximity to the outer surface of the applicator roll, whereby adhesive from the roll is transferred to an outer surface of each of said pads; a dispensing magazine for retaining a plurality of individual labels in a stack, with the lowermost label in the stack being located in a downstream path of travel of the transfer pads after each of said transfer pads has engaged the outer surface of the applicator roll to receive adhesive hereon, each of said pads, with the adhesive thereon, being rotated into close proximity with the lower surface of the lowermost label in the magazine for selectively and sequentially applying the adhesive to the lowermost label in the stack and for removing said lowermost label from the stack through surface adhesion to releasably secure said lowermost label to each of said transfer pads; an irradiating station adjacent the transfer member downstream of said dispensing magazine, said irradiating station including a rotatable member for receiving the individual labels with the adhesive thereon from the transfer pads, and directing the labels through an irradiating section to thereby a least partially cure the adhesive and render it sufficiently tacky to effectively adhere each of the individual labels to a container; a container handling device for receiving containers at an inlet; moving said containers through a label application section, and directing the containers with the labels applied thereon to an outlet; said irradiating station being positioned adjacent to the container handling device such that the individual labels with the at least partially cured adhesive thereon are directed sequentially into engagement with the periphery of discrete containers as the discrete containers are directed through the label application section to thereby effectively seal the labels to the containers. 3. The apparatus of claim 2, wherein the rotatable applicator roll is a gravure roll including cells thereon for receiving the radiation curable adhesive therein.4. The apparatus of claim 3, wherein each of the transfer pads includes a generally smooth surface onto which the adhesive is applied by the applicator roll.5. The apparatus of claim 4, wherein each of the transfer pads includes an outer member comprising an elastomeric material providing the smooth surface for receiving the radiation curable adhesive thereon.6. The apparatus of claim 5, wherein the elastomeric material is a photopolymer material.7. The apparatus of claim 2, wherein said radiation curable adhesive is an adhesive curable by ultraviolet radiation.8. The apparatus of claim 3, wherein said radiation curable adhesive is an adhesive curable by ultraviolet radiation.9. The apparatus of claim 4, wherein said radiation curable adhesive is an adhesive curable by ultraviolet radiation.10. The apparatus of claim 5, wherein said radiation curable adhesive is an adhesive curable by ultraviolet radiation.11. The apparatus of claim 6, wherein said radiation curable adhesive is an adhesive curable by ultraviolet radiation.
