Abstract
A zipper with at least one curve includes a first tape and a second tape, and interlocking elements attached to the first tape and the second tape, wherein the first tape and the second tape are curved, and wherein a curve of at least one of the tapes was caused by compaction of that tape.
Claims22
A method of making a zipper, the method comprising:
- compacting a first tape to form a compacted first tape having a first degree of compaction;
- compacting a second tape to form a compacted second tape having a second degree of compaction;
- and
- attaching interlocking elements to the compacted first tape;
- and
- attaching interlocking elements to the second compacted tape,
- wherein the first degree of compaction is distinct from the second degree of compaction,
- wherein at least a portion of the first tape and at least a portion of the second tape are curved.
5 more elements
A method comprising:
- providing a first zipper, the first zipper comprising a first tape and a second tape and first interlocking elements attached to the first tape and the second tape;
- providing a second zipper, the second zipper comprising a third tape and a fourth tape and second interlocking elements attached to the third tape and the fourth tape;
- and
- forming a third zipper from (i) the first tape and a plurality of the first interlocking elements and (ii) the third tape and a plurality of the second interlocking elements,
- wherein at least a portion of the first tape and at least a portion of the third tape are curved,
- wherein a curve of the first tape was caused, at least in part, by compaction of the first tape.
3 more elements
A method comprising:
- making a first zipper, the first zipper comprising a first tape and a second tape and first interlocking elements attached to the first tape and the second tape;
- making a second zipper, the second zipper comprising a third tape and a fourth tape and second interlocking elements attached to the third tape and the fourth tape;
- and
- forming a third zipper from the first tape and a plurality of the first interlocking elements and the third tape and a plurality of the second interlocking elements,
- wherein at least a portion of the first tape and at least a portion of the third tape are curved,
- wherein a curve of the first tape was caused, at least in part, by compaction of the first tape, and
- wherein a curve of the third tape was caused, at least in part, by compaction of the third tape.
