Abstract
Abstract A method of producing blocks of self-adhesive labels or the like involves feeding continuously to a cutting device a continuous label stock which on one face has a number of repeated images overlaid by a release coating and on the other face has a pressure-sensitive adhesive coating. In the cutting device a succession of sheets, each having more than one image, is cut from the stock and the sheets are formed into a stack of superimposed cut sheets, either simultaneously with the cutting or in a subsequent step. Finally, a number of blocks of superimposed labels or the like, each having a single image, are cut from the stack of sheets. Various methods of applying the labels from the blocks to cylindrical or non-cylindrical bodies are given.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
97 words
A method of producing blocks of self-adhesive products, which method comprises feeding continuously to a cutting device a continuous flexible web having on a first face thereof a multiplicity of repeated images overlaid by a release coating and further having on a second face thereof a pressure-sensitive adhesive coating, cutting from the web a succession of cut sheets each having at least two said images thereon, forming a stack of superimposed cut sheets, and subsequently cutting said stack to form at least two blocks of superimposed self-adhesive products, each said product having a single said image thereon.
Claim 2
Independent Claim
97 words
A method of producing blocks of self-adhesive products, which method comprises feeding continuously to a cutting device a continuous flexible web having on a first face thereof a multiplicity of repeated images overlaid by a release coating and further having on a second face thereof a pressure-sensitive adhesive coating, cutting from the web a succession of cut sheets each having at least two said images thereon, forming a stack of superimposed cut sheets, and subsequently cutting said stack to form at least two blocks of superimposed self-adhesive products, each said product having a single said image thereon.
Claim 3
Dependent Claim
33 words
A method according to claim 1, wherein the cutting of the sheets from the continuous flexible web and the forming of a stack of superimposed cut sheets are performed in successive separate operations.
Claim 4
Dependent Claim
49 words
A method according to claim 2, wherein the cutting of the sheets from the continuous flexible web comprises an incomplete cutting by means of a rotary die and the resulting incompletely cut sheets are subsequently separated from the stock and simultaneously stacked, by means of a shear cutting device.
Claim 5
Dependent Claim
34 words
A method according to claim 1, wherein the cutting of the sheets from the continuous flexible web and the forming of a stack of superimposed cut sheets are carried out in a single operation.
Claim 6
Dependent Claim
31 words
A method according to claim 4, wherein said single cutting and stacking operation is carried out by means of a die set consisting of a male die and a female die.
Claim 7
Dependent Claim
30 words
A method according to claim 5, wherein the surface surrounding the cutting area of the female die is modified to reduce any adhesion of said adhesively-coated web to that surface.
Claim 8
Dependent Claim
28 words
The method of claim 1, wherein said products are selected from the group consisting of labels, decorative wallpaper strips or tiles, interlocking cut shapes, tape and photographic products.
Claim 9
Dependent Claim
14 words
The method of claim 1, wherein the self-adhesive products are dispensed from a roll.
Claim 10
Independent Claim
161 words
A method of producing blocks of self-adhesive products, which method comprises the steps of: (a) applying a multiplicity of like images to a first face of a continuous flexible web; (b) applying a layer of a release material to said first face over said images; (c) applying a layer of a pressure-sensitive adhesive to a second face of said continuous flexible web; (d) feeding said continuous flexible web continuously to a die set comprising a male die and a hollow female die; (e) cutting said continuous flexible web in said die set to produce a succession of like cut sheets superimposed upon each other within said hollow female die, each of said cut sheets having a plurality of said images thereon; and (f) cutting said superimposed sheets in a direction generally perpendicular to the plane of the sheets, whereby to divide said stack into a plurality of blocks of superimposed self-adhesive products, each said product having only one said image thereon.
Claim 11
Independent Claim
161 words
A method of producing blocks of self-adhesive products, which method comprises the steps of: (a) applying a multiplicity of like images to a first face of a continuous flexible web; (b) applying a layer of a release material to said first face over said images; (c) applying a layer of a pressure-sensitive adhesive to a second face of said continuous flexible web; (d) feeding said continuous flexible web continuously to a die set comprising a male die and a hollow female die; (e) cutting said continuous flexible web in said die set to produce a succession of like cut sheets superimposed upon each other within said hollow female die, each of said cut sheets having a plurality of said images thereon; and (f) cutting said superimposed sheets in a direction generally perpendicular to the plane of the sheets, whereby to divide said stack into a plurality of blocks of superimposed self-adhesive products, each said product having only one said image thereon.
