Abstract

A method for forming a double-sided loop strap includes: receiving a continuous longitudinal strip of loop material including a strip-form base bearing a field of upstanding loops on a fastening side of the strip bounded by opposite longitudinal edges, folding each of the longitudinal edges away from the fastening side, such that the base overlaps itself, and securing the folded edges in place by permanently bonding together overlapped areas of the base to form the double-sided loop strap.

First claim

What is claimed is:

1. A double-sided loop strap, comprising:
a first side comprising a first loop-bearing surface; and
a second side opposite the first side, the second side comprising a second loop-bearing surface and an adjacent grip area covered by a grip material forming an exposed grip surface,
wherein the exposed grip surface is recessed below the second loop-bearing surface, and
wherein the first loop-bearing surface is of a loop material forming one broad side of the strap opposite the grip surface, and the second loop-bearing surface is of a loop material having a longitudinal edge adjacent to the grip surface and secured by the grip material.

2. The double-sided loop strap of claim 1 , wherein the grip area comprises a longitudinally continuous lane bounded on both sides by loop material.

3. The double-sided loop strap of claim 1 , wherein the grip surface features protrusions of the grip material.

4. The double-sided loop strap of claim 1 , wherein the grip area has a lateral extent of between 10 and 90 percent of an overall width of the strap.

5. The double-sided loop strap of claim 1 , wherein the second loop-bearing surface is of a loop material having an edge bounding a hole through the second loop-bearing surface.

6. The double-sided loop strap of claim 1 , wherein the grip material has a dynamic coefficient of friction that is greater than about 0.3.

7. A double-sided loop strap, comprising:
a first side comprising a loop-bearing surface; and
a second side opposite the first side, the second side comprising a second loop-bearing surface and an adjacent grip area covered by a grip material forming an exposed grip surface,
wherein the exposed grip surface is bounded by an edge of the second loop-bearing surface, and
wherein the grip material extends underneath and bonds the edge.

8. The double-sided loop strap of claim 7 , wherein the edge is a continuous longitudinal edge of the second loop-bearing surface.

9. The double-sided loop strap of claim 7 , wherein the edge bounds a hole through the second loop-bearing surface.

10. The double-sided loop strap of claim 7 , wherein the grip material includes a foaming agent.

11. The double-sided loop strap of claim 7 , wherein a portion of the grip surface is level with or above the second loop-bearing surface.
