Abstract

A braiding machine including several rings for passing spools. The braiding machine may include an inner ring and an outer ring which may be comprised of rotor metals, and an intermediate ring that may be comprised of horn gears. Spools may pass along the inner and outer rings, and the horn gears in the intermediate ring may allow spools to be passed back and forth between the inner ring and the outer ring.

5. The braiding machine of claim 1, wherein each of the first plurality of rotor metals comprises a respective concave side, wherein each of the plurality of horn gears comprises a respective slot, and wherein the concave sides of the first plurality of rotor metals have a different diameter than the slots of the plurality of horn gears.

6. The braiding machine of claim 5, wherein each of the third plurality of rotor metals includes a respective concave side, and wherein the concave sides of the third plurality of rotor metals have a different diameter than the slots of the plurality of horn gears.

7. The braiding machine of claim 1, wherein each of the first plurality of rotor metals includes a pair of opposite concave sides, and wherein each of the plurality of horn gears includes four slots.

8. The braiding machine of claim 1, wherein the spool can be passed from a first spool moving element in the first ring to an adjacent second spool moving element in the first ring.

9. The braiding machine of claim 1, wherein the spool can be passed from a first spool moving element in the third ring to an adjacent second spool moving element in the third ring.

10. The braiding machine of claim 1, wherein a spool moving element in the first ring has a geometry that is symmetric about a rotation of 180 degrees.

11. The braiding machine of claim 1, wherein a spool moving element in the second ring has a geometry that is symmetric about a rotation of 90 degrees.

12. A braiding machine, comprising:
