Abstract

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.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 170 words
Apparatus for applying labels to articles which are moved sequentially through an application station, comprising: feeding means for feeding through the apparatus a web with labels thereon and activated adhesive on one side thereof, a severing station at which the labels are cut from the web, a drum and co-operating roller comprising a nip forming said severing station, said drum being an anvil, and die cutting edges on said co-operating roller, the cutting edges serving to cut the labels from the web by cutting through the adhesive side of the web and including a lubricating roller in tangential contact with the co-operating roller, support means for supporting the lubricating roller so that it is free to float towards and away from the co-operating roller, and spring means for urging the lubricating roller against the co-operating roller, said lubricating roller carrying liquid lubricating medium which is applied to the co-operating roller as it rotates, keeping said die cutting edges clear of adhesive at least for a plurality of label cutting actions.
Claim 2
Dependent Claim 170 words
Apparatus for applying labels to articles which are moved sequentially through an application station, comprising: feeding means for feeding through the apparatus a web with labels thereon and activated adhesive on one side thereof, a severing station at which the labels are cut from the web, a drum and co-operating roller comprising a nip forming said severing station, said drum being an anvil, and die cutting edges on said co-operating roller, the cutting edges serving to cut the labels from the web by cutting through the adhesive side of the web and including a lubricating roller in tangential contact with the co-operating roller, support means for supporting the lubricating roller so that it is free to float towards and away from the co-operating roller, and spring means for urging the lubricating roller against the co-operating roller, said lubricating roller carrying liquid lubricating medium which is applied to the co-operating roller as it rotates, keeping said die cutting edges clear of adhesive at least for a plurality of label cutting actions.
Claim 3
Dependent Claim 25 words
Apparatus according to claim 1, wherein said drum is a vacuum drum to which cut labels are held when cut by the die cutting edges.
Claim 4
Dependent Claim 52 words
Apparatus according to claim 1 or 2, wherein said lubricating roller comprises a spindle having a resilient surface means which carries liquid lubricating medium, said surface being defined by a closed cell neoprene rubber flexible sleeve, which is in several spaced sections which are carried on collars independently rotatable on the spindle.
Claim 5
Dependent Claim 44 words
Apparatus according to claim 3, wherein said support means comprises a pair of pivotable spring loaded brackets which ensure that said lubricating spindle is resiliently urged onto the cooperating roller, but can readily be removed by swinging said brackets away from the co-operating roller.
Claim 6
Dependent Claim 27 words
Apparatus according to claim 4, wherein the position of the brackets may be adjusted to adjust the spring loading of the lubricating spindle on said co-operating roller.
