Abstract

Provided are adhesive tapes and methods of use. The adhesive tape provides a flying splice of fibrous materials. An example adhesive tape comprises an adhesive layer, a backing adjacent to the adhesive layer, and a non-adhesive mechanical fastener.

First claim

What is claimed is:

1. A method of providing a flying splice on a fibrous material, the method comprising:
providing an adhesive tape comprising:
an adhesive layer,
a backing adjacent to the adhesive layer, and
a non-adhesive mechanical fastener;

contacting the adhesive layer to a leading edge of a top winding of a first roll of the fibrous material;
fastening the non-adhesive mechanical fastener to a second from the top winding of the first roll of the fibrous material;
contacting the adhesive layer with an unwinding second roll of the fibrous material without stopping or slowing the unwinding of the second roll of the fibrous material; and
releasing the non-adhesive mechanical fastener from the second from the top winding of the first roll of the fibrous material; wherein the released non-adhesive mechanical fastener does not leave a residue on the second from the top winding of the first roll of the fibrous material.

2. The method of claim 1 , wherein the non-adhesive mechanical fastener comprises a shaped plastic.

3. The method of claim 2 , wherein the plastic of the shaped plastic is selected from the group consisting of nylons, polyesters, polyurethanes, polyvinyl chloride, polypropylene and any combination thereof.

4. The method of claim 2 , wherein the shape of the shaped plastic is selected from the group consisting of a single-sided hook shape, a half-sphere capped shape, a branched tree shape, a double-sided hook shape, a sphere capped shape, an open-loop shape, an arrow shape, a triangle capped shape, and any combination thereof.

5. The method of claim 1 , wherein the fibrous material is selected from the group consisting of textiles, cloth, fabric, wool, silk, cotton, flax, jute, nylon, polyester, acrylic, fur, spunlaid materials, spun-melt materials, spun-melt-spun materials, rayon, polyethylene terephthalate fibers, polypropylene fibers, staple nonwovens, flashspun materials, air-laid paper, fibrillated materials, and any combination thereof.

6. The method of claim 1 , further comprising a leading edge liner and a contact side liner; wherein the leading edge liner and the contact side liner are adjacent to and covering at least a portion of the adhesive layer.

7. A method of providing a flying splice on a fibrous material, the method comprising:
providing an adhesive tape comprising:
a first adhesive layer,
a second adhesive layer,
a backing adjacent to the first adhesive layer and the second adhesive layer, and
a non-adhesive mechanical fastener adjacent to the second adhesive layer;

contacting the second adhesive layer to a leading edge of a top winding of a first roll of the fibrous material;
fastening the non-adhesive mechanical fastener to a second from the top winding of the first roll of the fibrous material;
contacting the first adhesive layer with an unwinding second roll of the fibrous material without stopping or slowing the unwinding of the second roll of the fibrous material; and
releasing the non-adhesive mechanical fastener from the second from the top winding of the first roll of the fibrous material; wherein the released non-adhesive mechanical fastener does not leave a residue on the second from the top winding of the first roll of the fibrous material.

8. The method of claim 7 , wherein the non-adhesive mechanical fastener comprises a shaped plastic.

9. The method of claim 8 , wherein the plastic of the shaped plastic is selected from the group consisting of nylons, polyesters, polyurethanes, polyvinyl chloride, polypropylene, and any combination thereof.

10. The method of claim 8 , wherein the shape of the shaped plastic is selected from the group consisting of a single-sided hook shape, a half-sphere capped shape, a branched tree shape, a double-sided hook shape, a sphere capped shape, an open-loop shape, an arrow shape, a triangle capped shape, and any combination thereof.

11. The method of claim 7 , wherein the fibrous material is selected from the group consisting of textiles, cloth, fabric, wool, silk, cotton, flax, jute, nylon, polyester, acrylic, fur, spunlaid materials, spun-melt materials, spun-melt-spun materials, rayon, polyethylene terephthalate fibers, polypropylene fibers, staple nonwovens, flashspun materials, air-laid paper, fibrillated materials, and any combination thereof.
