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.

First claim

What is claimed is:

1. A braiding machine, comprising:
a support structure; and
a spool system, comprising:
a first set of spool moving elements arranged in a first ring on the support structure, the first set of spool moving elements comprising a first plurality of rotor metals;
a second set of spool moving elements arranged in a second ring on the support structure, the second set of spool moving elements comprising a plurality of horn gears;
a third set of spool moving elements arranged in a third ring on the support structure, the third set of spool moving elements comprising a second plurality of rotor metals; and
a spool with thread, the spool being mounted to a carrier element,

wherein the spool mounted to the carrier element can be passed between the first set of spool moving elements and the second set of spool moving elements and wherein the spool mounted to the carrier element can be passed between the third set of spool moving elements and the second set of spool moving elements, and
wherein the plurality of horn gears is displaced axially from the first plurality of rotor metals and the second plurality of rotor metals.

2. The braiding machine of claim 1 , wherein the second ring is concentrically arranged between the first ring and the third ring, and wherein the plurality of horn gears are positioned in overlapping fashion with the first plurality of rotor metals and the second plurality of rotor metals.

3. The braiding machine of claim 1 , wherein the first set of spool moving elements is equal in number to the third set of spool moving elements.

4. The braiding machine of claim 3 , wherein the second set of spool moving elements is equal in number to the first set of spool moving elements and the third set of spool moving elements.

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:
a support structure; and
a spool system, comprising:
a set of rotor metals arranged in a first ring on the support structure;
a set of horn gears arranged in a second ring on the support structure; and
a spool with thread, the spool being mounted to a carrier element,

wherein the spool mounted to the carrier element can be passed between the set of rotor metals in the first ring and the set of horn gears in the second ring, and
wherein the set of horn gears is displaced axially from a surface of the braiding machine a different distance than the set of rotor metals.

13. The braiding machine of claim 12 , wherein the set of horn gears and the set of rotor metals are arranged in an overlapping configuration relative to each other, and wherein the set of rotor metals includes a first rotor metal having a first convex side, a first concave side, a second convex side opposite the first convex side and a second concave side opposite the first concave side.

14. The braiding machine of claim 13 , wherein the first rotor metal is symmetric about a rotation of 180 degrees.

15. The braiding machine of claim 13 , wherein the set of horn gears includes a first horn gear with four slots, and wherein a diameter of each of the four slots is smaller than a diameter of the first and second concave sides of the first rotor metal.

16. The braiding machine of claim 15 , wherein the first horn gear is symmetric about a rotation of 90 degrees.

17. The braiding machine of claim 12 , wherein the carrier element is held in a gap formed between two adjacent rotor metals of the set of rotor metals while the spool is in the first ring.

18. The braiding machine of claim 12 , wherein the carrier element comprises a rotor engaging portion coupled to a rod portion, and wherein the rod portion of the carrier element is held in a slot of a horn gear in the set of horn gears while the spool is in the second ring.

19. The braiding machine of claim 12 , wherein the first ring is arranged concentrically with the second ring.

20. A braiding machine, comprising:
a support structure comprising a top surface; and
a spool system supported on the top surface, the spool system comprising:
a first set of rotor metals arranged in an inner ring on the support structure;
a set of horn gears arranged in an intermediate ring on the support structure;
a second set of rotor metals arranged in an outer ring on the support structure, wherein a first rotor metal of the first set of rotor metals is displaced from a first horn gear of the set of horn gears axially relative to the top surface; and
a spool with thread, the spool being mounted to a carrier element,

wherein the spool mounted to the carrier element can be passed between the first set of rotor metals and the set of horn gears and wherein the spool mounted to the carrier element can be passed between the second set of rotor metals and the set of horn gears.

21. The braiding machine of claim 20 , wherein the inner ring is concentrically arranged within the intermediate ring.

22. The braiding machine of claim 21 , wherein the intermediate ring is concentrically arranged within the outer ring.
