Composite prelaminated tapes for diaper closures

A roll of tape comprising an elongate 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 elongate 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 comprising an elongate strip of sheet backing material, having first and second edges, being substantially as wide as said tape composite, and having a layer of a first normally tacky and pressure-sensitive adhesive coated over substantially one surface of said backing material;
• (b) a layer of a second normally tacky and pressure-sensitive adhesive coated over approximately one-third of the layer of said first normally tacky and pressure-sensitive adhesive along the first edge thereof;
• (c) a fingerlift adhered to the first pressure-sensitive adhesive adjacent the second edge thereof;
• (d) a release tape, having first and second surfaces, the first surface adhered to said first layer of pressure-sensitive adhesive layer;
• (e) a layer of normally tacky and pressure-sensitive adhesive coated over the second surface of said release tape;
• and
• (f) a unifying strip centered along the junction of sad second adhesive layer and the adhesive layer on said release tape and adhered to said adhesive layers.
