## Abstract

A paper web splice tape which is usable to splice a free end of a new paper web to a depleting paper web is formed as a double sided adhesive tape. A continuous high strength adhesive layer is provided on an outer surface of the splice tape and is engageable with the depleting web. The inner side of the splice tape is separated into a high strength adhesive zone, an adhesive free zone and an easily releasable adhesive zone.

## Claims

### Claim 1

A paper web splice tape usable to splice a leading edge of a new paper web roll to a depleting paper web, said paper web splice tape comprising:
a central elongated continuous carrier tape having a first outwardly facing surface and a second inwardly facing surface, said first and second surfaces being opposing;
first and second spaced longitudinally extending, inwardly facing zones on said second surface of said carrier tape, said first and second zones being spaced by a central, longitudinally extending zone, said first, second and central zones extending continuously along the length of said carrier tape;
a high strength continuous adhesive layer applied directly to and completely covering said first outwardly facing surface of said carrier tape and having an outwardly facing high strength adhesive surface, said outwardly facing high strength adhesive surface being directly securely adherable to a depleting paper web;
a high strength adhesive band applied directly to and completely covering said longitudinally extending, inwardly facing first zone of said second surface of said carrier tape and having an inwardly facing high strength adhesive surface, said inwardly facing high strength adhesive surface being directly engageable with an outer surface of a free end of a first layer of a new paper roll;
an easily releasable adhesive band applied directly to and completely covering said longitudinally extending, inwardly facing second zone of said second surface of said carrier tape and having an inwardly facing easily releasable adhesive surface, said inwardly facing easily releasable adhesive surface being directly releasably engageable with an outer surface of a second layer of a new paper web roll adjacent a free end of a new paper roll; and
an adhesive free inwardly facing area formed by said central zone on said second surface of said carrier tape, said adhesive free area separating said high strength adhesive band applied to said first zone from said easily releasable adhesive band applied to said second zone and overlying an edge of a free end of a first layer of a new paper roll when said paper web splicing tape is applied to a new paper roll.

### Claim 2 (depends on 1)

The paper web splice tape of claim 1 wherein said paper web splice tape has a uniform cross-section.

### Claim 3 (depends on 1)

The paper web slice tape of claim 1 wherein said easily releasable adhesive band is a one time adhesive layer.
