Abstract

To ensure during the braiding of braiding cores, which have a complex braiding core geometry or vastly different side lengths, that the braiding threads are always correctly following the braiding core contour in terms of storage, at least two braiding rings are provided, which have a constant opening cross-section and are arranged in series directly adjacent to one another. The opening cross-sections delimited by the braiding rings overlap at least partially. The braiding rings are adjustable independently of one another.

First claim

What is claimed is:

1. A braiding machine for braiding a braiding core that is fed in a continuous manner, the braiding machine comprising:
at least two braiding thread spools;
at least two braiding rings having a constant opening cross section disposed in series so as to be mutually adjacent such that the constant opening cross sections delimited by the at least two braiding rings form an overlap opening that corresponds geometrically to a momentary braiding core cross section, wherein
the at least two braiding rings are disposed between the braiding thread spools and a run-on point of braiding threads onto the braiding core, and
the at least two braiding rings are disposed so as to be individually adjustable laterally relative to an axis passing through the constant opening cross sections of the at least two braiding rings.

2. The braiding machine according to claim 1 , wherein the braiding machine is a circular braiding machine.

3. The braiding machine according to claim 1 , wherein
the at least two braiding rings each have an annular opening cross section.

4. The braiding machine according to claim 1 , wherein
the at least two braiding rings each have an ellipsoidal opening cross section.

5. The braiding machine according to claim 1 , wherein
the at least two braiding rings have an ovoid opening cross section.

6. The braiding machine according to claim 1 , wherein
the at least two braiding rings are disposed in a mutually engaging manner.

7. The braiding machine according to claim 1 , wherein
the at least two braiding rings include three braiding rings of identical type are provided so as to be directly adjacent.

8. The braiding machine according to claim 1 , wherein
each braiding ring of the at least two branding rings in a braiding ring plane is disposed so as to be adjustable in a bi-axial translatory manner.

9. The braiding machine according to claim 8 , wherein
each braiding ring of the at least two branding rings is adjustable by way of a linear guide.

10. The braiding machine according to claim 1 , wherein
each braiding ring of the at least two branding rings is adjustable by way of a linear guide.

11. The braiding machine according to claim 1 , wherein
a spindle drive that is capable of separate actuation is provided for adjusting each one of the at least two braiding rings.

12. The braiding machine according to claim 6 , wherein
a spindle drive that is capable of separate actuation is provided for adjusting each one of the at least two braiding rings.

13. The braiding machine according to claim 7 , wherein
a spindle drive that is capable of separate actuation is provided for adjusting each one of the at least two braiding rings.
