Abstract

Abstract A process in which a carrier strip has a release coated web marginally secured thereto, the latter releaseably 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: 4
Claim 1
Independent Claim 28 words
The process of claim 1 in which the cutting of the web and the tape is along lines other than normal to the longitudinal edges of the web.
Claim 2
Dependent Claim 82 words
The process of claim 2 in which the carrier strip, release coated web and the tape are moved linearly in being assembled, said strip being flexible, and in which the lines along which the tape and web are cut are slits at an angle such that each section of the tape linearly precedes the corresponding tab portion of the web whereby to prevent lateral displacement of each tab as the assembled composite of strip, web and tape is wound on a spool.
Claim 3
Dependent Claim 40 words
The process of claim 1 in which the area of mutual contact between the underside of each section of tape and the release coated surface of the corresponding tab is less than the remaining area of the section of tape.
Claim 4
Dependent Claim 42 words
The process of claim 1 in which the carrier strip and the web are adhesively secured together by a strip of an adhesive that is laid onto the carrier strip in advance of the strip and the web coming into contacting superposition.
