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

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.
Claim 12
Dependent Claim
41 words
A method according to claim 9, wherein the pressure-sensitive adhesive is applied to only a part of the area of the second face of said web such that adhesive is absent in the region of cutting of sheets from said web.
Claim 13
Dependent Claim
34 words
A method according to claim 9, wherein the cutting of said superimposed sheets to form said plurality of blocks is carried out with a cutter selected from the group comprising guillotines and die cutters.
Claim 14
Dependent Claim
24 words
A method according to claim 11, wherein the resulting blocks of superimposed self-adhesive products are subsequently modified by displacing adjacent products from vertical superimposition.
Claim 15
Dependent Claim
35 words
A method according to claim 9, wherein an apertured panel is disposed between said continuous web and said male die, whereby to assist disengagement of said web and said die after cutting of said web.
Claim 16
Dependent Claim
28 words
The method of claim 9, wherein said products are selected from the group consisting of labels, decorative wallpaper strips or tiles, interlocking cut shapes, tape and photographic products.
Claim 17
Dependent Claim
14 words
The method of claim 9, wherein the self-adhesive products are dispensed from a roll.
Claim 18
Independent Claim
167 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) cutting said web with a rotary cutter to incompletely separate from said web a succession of like partially cut sheets, each sheet having a plurality of said images thereon and being cut around a major proportion of its periphery; (e) in a subsequent step, continuously separating said incompletely separated sheets from said cut web and forming a stack of superimposed separated sheets; and (f) cutting said stack of superimposed sheets in a direction generally perpendicular to the plane of said sheets, whereby to divide said stack into a plurality of blocks of superimposed self-adhesive products, each said product having a single said image thereon.
