Abstract

A braiding machine comprising a support structure, a track, an enclosure, a plurality of rotor metals, and a passageway having a first opening and a second opening, and a method of forming an upper using a braiding machine, the method comprising braiding over a forming last that passes from a first side of a braiding point to a second side of the braiding point of the braiding machine. The braiding machine is capable of forming intricate braided structures and may include different sized rings and non-linear passageways through which a forming last passes. Multiple forming lasts may be attached together by connection mechanisms and passed through the braiding machine.

First claim

What is claimed is:

1. A system for forming braided structures over objects, the system comprising:
a braiding machine, comprising:
a support structure comprising an enclosure and a track extending around the enclosure;
a plurality of spools with thread positionable along the track;
a passageway extending through the enclosure, the passageway having a first opening at a first end of the passageway and a second opening at a second end of the passageway,
a braiding point located proximate the second opening of the passageway; and

a conveyor spaced from the braiding machine,
wherein the braiding machine and the conveyor are positioned so that as an object is advanced through the passageway and from a first side of the braiding point to a second side of the braiding point while the plurality of spools with the thread are moved around the track, the thread is deposited about the object to form a braided structure thereon and the object with the braided structure formed thereon is advanced onto the conveyor.

2. The system of claim 1 , further comprising a thread tensioner coupled to the braiding machine between the track and the braiding point.

3. The system of claim 1 , wherein the passageway is non-linear between the first opening and the second opening.

4. The system of claim 1 , wherein the conveyor comprises a belt.

5. The system of claim 4 , wherein a plane defined by the belt is oriented perpendicular to an axis of the braiding point.

6. The system of claim 1 , wherein the object comprises a first object of a plurality of objects, and wherein the plurality of objects are movably coupled together in sequence with a plurality of flexible connection mechanisms that are respectively interposed between the plurality of objects.

7. The system of claim 1 , further comprising a thread-organization ring coupled to the braiding machine.

8. The system of claim 7 , wherein the thread-organization ring is removably coupled to the braiding machine, and wherein the thread-organization ring is replaceable with any one of a plurality of other thread-organization rings of different sizes.

9. The system of claim 1 , wherein the object is a shoe last, and wherein the braided structure is a braided shoe upper.

10. A system for forming braided structures over objects, the system comprising:
a braiding machine, comprising:
a support structure comprising an enclosure and a track extending around the enclosure;
a plurality of spools with thread positionable along the track;
a passageway extending through the enclosure, the passageway having a first opening at a first end of the passageway and a second opening at a second end of the passageway, wherein the passageway is non-linear,
a braiding point located proximate the second opening of the passageway; and

a plurality of objects on which braided structures can be formed by the braiding machine, the plurality of objects movably coupled together in sequence with a plurality of respectively interposed flexible connection mechanisms,
wherein each one of the plurality of respectively interposed flexible connection mechanisms comprises a non-rigid, pliable material.

11. The system of claim 10 , wherein the braiding machine is configured so that as each one of the plurality of objects is advanced through the passageway and from a first side of the braiding point to a second side of the braiding point while the plurality of spools with the thread are moved around the track, the thread is deposited on each one of the plurality of objects to form a braided structure thereon.

12. The system of claim 10 , further comprising a thread tensioner coupled to the braiding machine between the track and the braiding point.

13. The system of claim 10 , wherein the plurality of objects comprises a plurality of shoe lasts.

14. The system of claim 13 , wherein the plurality of shoe lasts are all of a common size.

15. The system of claim 13 , wherein the plurality of shoe lasts comprises at least two shoe lasts of different sizes.

16. The system of claim 10 , further comprising a conveyor spaced from the braiding machine, wherein the plurality of objects with the braided structures formed thereon are advanced onto the conveyor during a braiding process.

17. The system of claim 10 , wherein the plurality of respectively interposed flexible connection mechanisms are each formed of rubber.

18. A system for forming braided structures over objects, the system comprising:
a braiding machine, comprising:
a support structure comprising an enclosure and a track extending around the enclosure;
a plurality of spools each having a tensile element and positionable along the track;
a passageway extending through the enclosure, the passageway having a first opening at a first end of the passageway and a second opening at a second end of the passageway,
a braiding point located proximate the second opening of the passageway; and

a conveyor spaced from the braiding machine,
wherein the braiding machine and the conveyor are positioned so that as an object is advanced through the passageway and from a first side of the braiding point to a second side of the braiding point while the plurality of spools each having the tensile element are moved around the track, the tensile element is deposited about the object to form a braided structure thereon and the object with the braided structure formed thereon is advanced onto the conveyor.
