Abstract

Abstract A process in which a carrier strip has a release coated web marginally secured thereto, the latter releasably adherently mounting a longitudinally extending tape having a pressure sensitive adhesive on its underside. The release coated strip is longitudinally severed with the line of severance being spanned by the adhesive coated tape. Subsequently, the combined span of the tape and a marginal portion of the release coated stock that is freely superposed on the carrier strip, are transversely slit defining a plurality of discrete pressure sensitive adhesive backed sections of tape, each provided with a corresponding tab by means of which each discrete section of tape can be peeled from the composite structure for application to another article. The process produces a roll of individually dispensible, pressure sensitive adhesive tape sections, each with its corresponding tab being so angularly related to the length of the composite structure as to facilitate winding up of the product, in the process of manufacture, to protectively enclose the tabs between successive coils of the carrier strip. Upon unwinding of the roll through a specially adapted guide means of a dispensing apparatus, each tab is individually projected out of the plane of the carrier strip to provide clearance for grasping a free end of the tab stripping the associated adhesive backed sheet article from the roll. The carrier strip and tape may have different characteristics of light reflectivity, controlling an automatic feed system for the dispensing apparatus, cooperatively associated with a photoelectric light cell or the like.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 24 words
A composite assembly as in claim 1 in which said coating on the expoSed face of said superposed sheet has relatively high release properties.
Claim 2
Dependent Claim 47 words
A composite assembly as in claim 1 in which said section of tape has a greater portion of the area of its adhesive coated underside in contact with said first one of the two parts of said superposed sheet than is in contact with said second part.
Claim 3
Dependent Claim 77 words
A composite assembly as in claim 1 in which: the area of mutual contact of the adhesive coated underside of said tape and said second, tab part of said superposed sheet is adapted to permit lateral separation of said second, tab portion from said tape in response to tension in said second, tab part when the balance of the area of adhesive coated underside of said section of tape is held against lateral displacement on a surface.
Claim 4
Dependent Claim 39 words
A composite assembly as in claim 1 in which: said section of tape is of oblong parallelogram plan configuration and comprises a metallic foil, said second tab part being arranged as a longitudinal extension of said section of tape.
Claim 5
Dependent Claim 22 words
A composite assembly as in claim 1 in which said two parts of said release coated sheet constitute but cut parts thereof.
Claim 6
Dependent Claim 244 words
An article of manufacturing comprising: an elongated carrier strip; an elongated strip of flexible sheet material, having an upwardly facing release coated surface, in parallel contacting superposition on said carrier strip; an elongated flexible tape having a pressure sensitive adhesive on the underside thereof in parallel adherently contacting superposition on the upper surface of said release coated strip; said release coated strip being longitudinally divided into discrete, contiguous first and second marginal portions along a line that is spanned by said tape whereby said discrete portions are adhesively held against relative lateral displacement; longitudinally extending means securing said first marginal portion of said release coated strip to said carrier strip; said tape having that longitudinal edge on said second marginal portion of said release coated strip spaced from the edge of said second marginal portion; said tape and said release coated strip being divided into discrete areas along lines extending transversely thereof at intervals spaced longitudinally thereof to define a plurality of discrete sections of said tape and of said second marginal portions of said release coated strip; each of said sections of tape being adhesively secured to a corresponding discrete section of said second marginal portion of said release coated strip with a tab area of the release coated strip defined between said edges of said tape and said second marginal portion; each of said tab areas serving to peel the corresponding section of tape from adherent contact with said first marginal portion.
Claim 7
Dependent Claim 54 words
An article as in claim 7 in which: said carrier strip has a width exceeding the width of and underlying said second marginal portion of said release coated strip; said article being coiled with successive coils of said carrier strip protectively enclosing a coil of said discrete sections of said second marginal portion therebetween.
Claim 8
Dependent Claim 22 words
An article as in claim 7 in which said release coated strip is longitudinally butt cut to define said two marginal portions.
Claim 9
Dependent Claim 23 words
An article as in claim 7 in which said tape and said release coated strip are butt cut to define said discrete portions.
Claim 10
Dependent Claim 24 words
An article as in claim 7 in which said first marginal portion of said release coated strip is adhesively secured to said carrier strip.
Claim 11
Dependent Claim 42 words
An article as in claim 7 in which said lines along which said tape and said second marginal portion of said release coated strip are divided each have a length exceeding the combined span of said tape and said second marginal portion.
Claim 12
Dependent Claim 33 words
An article as in claim 12 in which said tape incorporates a lamination of metallic foil and is of uniform width whereby each discrete area of said tape has an oblong parallelogram planform.
Claim 13
Dependent Claim 86 words
An article as in claim 12 iN which: said carrier strip has a width exceeding the width of and underlying said second marginal portion of said release coated strip; said article being coiled with successive coils of said carrier strip protectively enclosing a coil of said discrete sections of said second marginal portion therebetween; said article being coiled in a take-up direction for inserting each of said discrete areas of tape into the coil in advance of the corresponding discrete area of said second marginal portion.
Claim 14
Dependent Claim 33 words
An article as in claim 7 in which each of said discrete areas of tape has a greater area of adhesive contact with said first marginal portion than with said second marginal portion.
Claim 15
Dependent Claim 91 words
An article as in claim 7 in which the area of mutual contact of the adhesive coated underside of said tape and said second marginal portion of said release coated strip is adapted to permit lateral separation of said discrete area of said second marginal portion from the corresponding discrete area of tape in response to tension in said tab area of said second marginal portion when the balance of the area of adhesive coated underside of the corresponding discrete area of tape is held against lateral displacement on a surface.
