Abstract
An improved labeling device of the type including a rotatable transfer drum for transferring containers onto which labels are to be affixed; an adhesive coating drum for applying an adhesive coating; and a label supply drum for first holding and then releasing labels. The improvement comprises arranging the components such that the containers carried by the rotatable container transfer drum first contact the adhesive coating drum and subsequently the adhesive coated containers while still carried by the container transfer drum are brought into contact with labels carried by the label supply drum, thereby making it possible to apply labels to containers at high-speeds and to use strong adhesives.
Claims4
In a labeling device of the type comprising:
- a rotatable container transfer drum means for transferring containers onto which labels are to be affixed;
- an adhesive coating drum means for applying an adhesive material;
- and
- a label supply drum means for first holding labels and then releasing them, said label supply drum means comprising a drum having protrusions spaced along its periphery, suction outlets to ports on the surface of said protrusions, and valve means for alternately applying and releasing suction applied to said suction ports, thereby first gripping and then releasing said labels;
- wherein the improvement comprises contacting the containers carried by said rotatable container transfer drum means with said adhesive coating drum means, thereby applying adhesive to said containers and subsequently contacting said adhesive coated containers while still carried by said container transfer drum means to said labels supported on said label supply drum means, thereby applying labels to said adhesive coated containers.
