Abstract
Abstract To produce a continuous reel of self-adhesive labels without the limitations on size and quality involved in printing on a continuous web, the labels are initially produced as separate flat sheets, cut to finished size and stacked, and are then fed in succession from the stack to an adhesive applicator, through an adhesive drying device, and applied successively by their adhesive coated sides to a continuous web of release paper which is then reeled. The labels may be fed from the stack to the surface of a drum, by a reciprocating suction bar, and held by suction on the surface of the drum while the adhesive is applied and dried. The web of release paper is then brought into contact with the labels at the point at which the suction ceases to hold them on the drum.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
123 words
A process for the production of a continuous reel of selfadhesive labels, wherein the labels are produced as separate flat sheets cut to finished size and stacked, the separate labels are then fed in succession from the stack onto the surface of a drum and held thereon by vacuum means while being fed to an applicator by which they are coated individually on their reverse sides with a pressure-sensitive adhesive composition, the adhesive is dried by passing the labels through a hot air chamber extending about a substantial part of the periphery of the drum and the labels are applied successively by their adhesive coated sides to a continuous web of release paper which moves against said drum and which is then reeled.
Claim 2
Dependent Claim
123 words
A process for the production of a continuous reel of selfadhesive labels, wherein the labels are produced as separate flat sheets cut to finished size and stacked, the separate labels are then fed in succession from the stack onto the surface of a drum and held thereon by vacuum means while being fed to an applicator by which they are coated individually on their reverse sides with a pressure-sensitive adhesive composition, the adhesive is dried by passing the labels through a hot air chamber extending about a substantial part of the periphery of the drum and the labels are applied successively by their adhesive coated sides to a continuous web of release paper which moves against said drum and which is then reeled.
Claim 3
Dependent Claim
35 words
A process according to claim 1 wherein the application of the labels to the web of release paper is controlled by a photo-electric cell sensitive to the presence of a preceding label on the web.
Claim 4
Dependent Claim
33 words
A process according to claim 1 wherein after application of the labels, the web with the labels thereon is passed between a pair of pressure rollers to ensure the attachment of the labels.
Claim 5
Dependent Claim
129 words
Apparatus for producing continuous reels of self-adhesive labels, comprising means for supporting a stack of labels in the form of separate flat sheets cut to finished size, means for feeding separate cut labels in succession from the stack to an applicator which is arranged to coat the reverse sides of the labels individually with a pressure-sensitive adhesive composition, a rotatable drum having internal suction means for receiving and holding the labels on its periphery with their reverse sides outwards, drying means extending around a substantial part of the periphery of the drum for drying the adhesive on the reverse sides of the labels, means for subsequently applying the labels successively by their adhesive coated sides to a continuous web of release paper, and means for reeling the continuous web.
Claim 6
Dependent Claim
129 words
Apparatus for producing continuous reels of self-adhesive labels, comprising means for supporting a stack of labels in the form of separate flat sheets cut to finished size, means for feeding separate cut labels in succession from the stack to an applicator which is arranged to coat the reverse sides of the labels individually with a pressure-sensitive adhesive composition, a rotatable drum having internal suction means for receiving and holding the labels on its periphery with their reverse sides outwards, drying means extending around a substantial part of the periphery of the drum for drying the adhesive on the reverse sides of the labels, means for subsequently applying the labels successively by their adhesive coated sides to a continuous web of release paper, and means for reeling the continuous web.
Claim 7
Dependent Claim
11 words
Apparatus according to claim 4 wherein the applicator comprises a roller.
Claim 8
Dependent Claim
12 words
Apparatus according to claim 4 wherein the applicator comprises a doctor blade.
Claim 9
Dependent Claim
18 words
Apparatus according to claim 4 wherein the applicator comprises means for spraying the adhesive on to the labels.
Claim 10
Dependent Claim
18 words
Apparatus according to claim 4 wherein the applicator comprises means for screening the adhesive on to the labels.
Claim 11
Dependent Claim
24 words
Apparatus according to claim 4 wherein the means for feeding the cut labels from the stack to the applicatoR comprise a reciprocable suction bar.
Claim 12
Dependent Claim
21 words
Apparatus according to claim 6 wherein the drying means comprises an enclosure and means for supplying hot air to the enclosure.
Claim 13
Dependent Claim
35 words
Apparatus according to claim 6 wherein the drum has a perforated cylindrical wall and a plurality of chambers connected to suction ducts are disposed in close proximity to the inner surface of the drum wall.
