Double-sided fasteners
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.
1. A double-sided loop strap, comprising:
a continuous longitudinal strip of loop material comprising a base bearing a field of upstanding hook-compatible loops on a fastening side of the strip bounded by opposite longitudinal edges of the strip, the longitudinal edges folded away from the fastening side of the strip to overlap the base; and
a plurality of bonded regions of fused loop material permanently securing the strip in a folded condition, the plurality of bonded regions comprising:
a first set of one or more bonded regions overlapping and extending along at least one of the longitudinal edges; and
a second set of bonded regions comprising a patterned array of bonded regions distributed outboard of the longitudinal edges.
2. The loop strap of claim 1 , wherein the first set of one or more bonded regions defines a first ratio of bonded-to-unbonded area and the second set of bonded regions defines a second ratio of bonded-to-unbonded area that is different than the first ratio.
3. The loop strap of claim 2 , wherein the first ratio is greater than the second ratio.
4. The loop strap of claim 1 , wherein the longitudinal edges are adjacent, such that the first set of one or more bonded regions overlaps both of the longitudinal edges.
5. The loop strap of claim 1 , wherein each of the bonded regions of the first set is surrounded on all sides by an unbonded area of loop material.
6. The loop strap of claim 1 , wherein each of the bonded regions of the second set is surrounded on all sides by an unbonded area of loop material.
7. The loop strap of claim 6 , wherein each of the bonded regions of the second set has a generally circular shape.
8. The loop strap of claim 1 , wherein the bonded regions of the first set have at least one of a different shape, size, or pattern density than the bonded regions of the second set.
9. The loop strap of claim 1 , wherein the first set of one or more bonded regions comprises a row of bonded regions.
10. The loop strap of claim 1 , wherein the first set of one or more bonded regions comprises bonded regions shaped to form visually recognizable graphics.
11. The loop strap of claim 10 , wherein the recognizable graphics comprise alphanumeric characters.
12. The loop strap of claim 1 , wherein the second set of bonded regions comprises a uniform pattern of discrete bonded regions.
13. A double-sided loop strap, comprising:
a continuous longitudinal strip of loop material comprising a base bearing a field of upstanding hook-compatible loops on a fastening side of the strip bounded by opposite longitudinal edges of the strip, the longitudinal edges folded away from the fastening side of the strip to overlap the base; and
a plurality of bonded regions of fused loop material permanently securing the strip in a folded condition, the plurality of bonded regions comprising:
a first set of one or more bonded regions overlapping and extending along at least one of the longitudinal edges; and
a second set of bonded regions comprising a uniform patterned array of discrete bonded regions distributed outboard of the longitudinal edges,
wherein the longitudinal edges are adjacent, such that the first set of bonded regions overlaps both of the longitudinal edges;
wherein each of the bonded regions of the second set is surrounded on all sides by an unbonded area of loop material; and
wherein the bonded regions of the first set have at least one of a different shape, size, or pattern density than the bonded regions of the second set.
14. The loop strap of claim 13 , wherein the first set of one or more bonded regions defines a first ratio of bonded-to-unbonded area and the second set of bonded regions defines a second ratio of bonded-to-unbonded area that is different than the first ratio.
15. The loop strap of claim 14 , wherein the first ratio is greater than the second ratio.
16. The loop strap of claim 13 , wherein each of the bonded regions of the first set is surrounded on all sides by an unbonded area of loop material.
17. The loop strap of claim 16 , wherein each of the bonded regions of the second set has a generally circular shape.
18. The loop strap of claim 13 , wherein the first set of one or more bonded regions comprises a row of bonded regions.
19. The loop strap of claim 13 , wherein the first set of one or more bonded regions comprises bonded regions shaped to form visually recognizable graphics.
20. The loop strap of claim 19 , wherein the recognizable graphics comprise alphanumeric characters.
