Composite prelaminated tape system

Claim 1

A roll of tape comprising an elongated prelaminated tape composite wound convolutely upon itself about an annular core, especially suited for preparing a tape closure for disposable diapers by simply severing said elongated prelaminated tape composite parallel to the axis of the core at intervals corresponding to the predetermined width of said closure, the length of each such closure corresponding to the width of the roll of tape, said prelaminated tape composite comprising in combination (a) a fastening tape divided into a bonded section and a fastening section with the fastening tape comprising an elongated strip of sheet backing material, having first and second edges, being substantially as wide as said tape composite, and having a first layer of normally tacky and pressure-sensitive adhesive coated over substantially one surface of said backing material; (b) a first fingerlift adhered to the first layer of pressure-sensitive adhesive adjacent the second edge thereof; (c) a target tape, having first and second surfaces, the first surface adhered to said first layer of the pressure-sensitive adhesive layer; (d) a second layer of normally tacky and pressure-sensitive adhesive coated on the second surface of the target tape; (e) a second fingerlift adhered to the second layer of normally tacky and pressure sensitive adhesive; (f) a release tape, having first and second surfaces, the first surface adhered to said second layer of pressure-sensitive adhesive layer; (g) a third layer of normally tacky and pressure-sensitive adhesive coated over the second surface of said release tape; and (h) a unifying strip centered over said release tape edge and adhered to the third adhesive layer and to the first adhesive layer on the fastening tape by folding under the target tape.
