Abstract
A method and a device for braiding a rigid core with a braided structure with at least largely heavy-duty fibers and having regions with a differing number of layers. The device has a braiding machine, a linear displacing apparatus between the core and the braiding machine and a guiding apparatus for temporarily placing at least one element onto the uppermost layer of the braided structure in an automated manner, the at least one element having on the end face a defined stiff edge about which a braiding reversal may be created.
Claims14
A device for braiding a braided structure of at least largely of heavy-duty fibers having regions with a differing number of layers, comprising:
- a braiding machine;
- a fiber braiding core about which the braiding machine braids at least one layer of the braided structure;
- a linear displacing apparatus for reversible displacement of the core relative to the braiding machine during braiding;
- and
- a guiding apparatus which places at least one element onto the uppermost layer of the braided structure in an automated manner during a braiding reversal, the at least one element having defined stiff edge about which the fiber braiding is reversed.
A method for producing a braided structure having regions with a differing number of layers, comprising the steps of:
- braiding the braided structure in a number of layers onto a fiber braiding core wire a braiding machine, wherein the core is displaced relative to the braiding machine;
- and
- creating differing numbers of braided fiber layers in different regions of the core by reversing the movement of the core relative to the braiding machine,
- wherein, during at least one movement reversal, an element with a defined, stiff doubling-over edge is brought in an automated manner onto the uppermost braided layer to hold the braided layer at a predefined reversal point, and following the reversal movement, the braiding machine continues braiding to form a doubled-over braided layer.
