Apparatus for applying labels to articles

Abstract

The invention provides a method for applying labels to articles moved one by one past an application station. The labels are cut from a web which is fed through the machine, the web having adhesive applied to one side thereof which is pressure sensitive immediately before application to the articles. The machine includes cutting rollers which cuts through the adhesive side of the web in order to sever the labels therefrom, and the cutting edges of the cutting roller are kept clean by applying thereto liquid silicone or the like release composition. The liquid silicone is preferably applied by means of sleeves impregnated with the liquid silicone, such sleeves being rotatable on a spindle which is parallel to the axis of rotation of the cutting roller. The machine also has gearing coupling a device for feeding the web of materials to the cutting location. The cut labels are held by a vacuum drum before being applied to the articles and the gearing is also coupled to said vacuum drum. The machine is designed to operate continuously so that high speed application of the labels to the articles can be achieved.
