Abstract

A module element for driving and retaining braiding bobbin carriers on a predetermined bobbin path has at least one base element that can rotate about an axis of rotation, and at least one retaining element that is formed integrally with the base element. The retaining element is configured to releasably hold at least one braiding bobbin carrier offset from the rotary axis.

First claim

What is claimed is:

1. A braiding device for braiding fibrous semifinished products, the braiding device comprising:
a plurality of module elements for driving and retaining braiding bobbin carriers on a predetermined bobbin path, each of the module element comprising
a base element that is rotatable about an axis of rotation; and
a retaining element integrally formed with the base element,

wherein the retaining element releasably holds at least one braiding bobbin carrier offset from the axis of rotation using a first electromagnet,
wherein the plurality of module elements are arranged relative to each other such that at least one first retaining element of a first module element transfers the braiding bobbin carriers to a second retaining element of a second module element along the predetermined bobbin path, wherein the transfer occurs by suspending a magnetic field of the first electromagnet.

2. The braiding device element of claim 1 , wherein the plurality of module elements are configured to braid a flat fibrous semifinished product by being arranged in series or in parallel relative to each other.

3. The braiding device of claim 1 , wherein the plurality of module elements are configured to braid three-dimensional fibrous semifinished products by being arranged in several planes relative to each other.

4. The braiding device of claim 1 , wherein the plurality of module elements are configured to braid tubular fibrous semifinished products by being arranged in a circle.

5. The braiding device of claim 1 , further comprising:
a servicing device that forms at least one parking position for at least one braiding bobbin carrier.

6. The braiding device of claim 1 , further comprising:
a controller configured to control the plurality of module elements such that a multidimensional braid is formed with several braiding layers.

7. The braiding device of claim 6 , wherein the controller includes a memory unit storing predetermined bobbin paths that form predetermined fibrous semifinished products.

8. The braiding device of claim 1 , wherein the braiding bobbin carriers include at least one magnetic area that interacts with the retaining element of the module element.

9. The braiding device of claim 1 , wherein the second retaining element comprises a second electromagnet, and the transfer further occurs by initiating a magnetic field of the second electromagnet of the second retaining element.
