Abstract

The invention relates to a braiding bobbin for a braiding device. The braiding bobbin includes a cylindrical braiding spool, from which a previously wound, multilayer ribbon can be unwound, wherein a first layer of the ribbon consists of a pre-impregnated fiber film, and a second layer of the ribbon consists of a protective film. In addition, the braiding bobbin includes a bracket to which the braiding spool is frontally and rotatably fastened. Additionally provided for the braiding bobbin is a cylindrical additional spool for winding the protective film of the unwound ribbon and a deflection element. The deflection element is fastened to the bracket, wherein the deflection element is secured spaced apart in the radial direction R to the braiding spool and designed for deflecting the protective film from the braiding spool to the additional spool.

Claims

1. A braiding bobbin for a braiding device, the braiding bobbin comprising:

a multilayer ribbon including a first layer of a pre-impregnated fiber film and a second layer of a protective film,

a cylindrical braiding spool on which the multilayer ribbon is initially wound,

a bracket to which the braiding spool is rotatably fastened,

a cylindrical additional spool configured for winding the protective film of the multilayer ribbon when the multilayer ribbon is unwound, and

a deflection element fastened to the bracket, wherein the deflection element is secured at a distance in a radial direction to the braiding spool and is configured to deflect the protective film from the braiding spool to the additional spool,

wherein rotation of the braiding spool to unwind the multilayer ribbon therefrom causes rotation of the additional spool to wind the protective film thereto.

2. The braiding bobbin according to claim 1, wherein the braiding spool rotates about a braiding spool axis, terminates at a lowermost end, and terminates at an uppermost end distanced from the lowermost end by a height of the braiding spool along the braiding spool axis, wherein a lowermost plane perpendicular to the braiding spool axis includes the lowermost end, wherein an uppermost plane perpendicular to the braiding spool axis includes the uppermost end, and wherein the additional spool is not located between the lowermost plane and the uppermost plane.

3. The braiding bobbin according to claim 1, wherein the braiding spool and additional spool are coaxial.

4. The braiding bobbin according to claim 1, wherein an upper end of the braiding spool is directly joined with a lower end of the additional spool.

5. The braiding bobbin according to claim 1, wherein the braiding spool and additional spool are aligned coaxially about a coaxial axis or with respective axes aligned parallel to each other, and wherein the braiding spool and additional spool are distanced from one another along the coaxial axis or in the axial direction defined by the respective axes.

6. The braiding bobbin according to claim 1, wherein the additional spool is coupled with the braiding spool by at least one driving means, wherein rotating the braiding spool around the accompanying braiding spool rotational axis by means of the at least one driving means to unwind the multilayer ribbon therefrom causes the additional spool to rotate around an accompanying additional spool rotational axis to wind the protective film thereto.

7. The braiding bobbin according to claim 1, wherein:

an end of the braiding spool comprises a radially outwardly protruding braiding spool limiting disk, and/or

an end of the additional spool comprises a radially outwardly protruding additional spool limiting disk.

8. The braiding bobbin according to claim 7, wherein the deflection element extends in an axial direction from a first deflection element end to a second deflection element end, wherein the first deflection element end is situated radially outside relative to the braiding spool, the second deflection element end is situated radially outside relative to the additional spool, wherein the multilayer ribbon extends in a plane tangential to the braiding spool from the braiding spool to the first deflection element, wherein the protective film extends in a plane parallel the axis of the braiding spool from the first deflection element to the second deflection element, and wherein the protective film extends in a plane tangential to the additional spool from the second deflection element to the additional spool.

9. The braiding bobbin according to claim 8, wherein the deflection element comprises a first guiding element protruding in the radial direction for guiding the protective film.

10. The braiding bobbin according to claim 9, wherein the deflection element comprises a second guiding element protruding in the radial direction for guiding the protective film.

11. The braiding bobbin according to claim 9, wherein the braiding spool rotates about a braiding spool axis, terminates at a lowermost end, and terminates at an uppermost end distanced from the lowermost end by a height of the braiding spool along the braiding spool axis, wherein a lowermost plane perpendicular to the braiding spool axis includes the lowermost end, wherein an uppermost plane perpendicular to the braiding spool axis includes the uppermost end, and wherein the first guiding element is situated between the lowermost plane and the uppermost plane, and wherein the second guiding element is situated such that the uppermost plane is between the second guiding element and the lowermost plane.

12. A braiding bobbin for a braiding device, the braiding bobbin comprising:

a cylindrical braiding spool configured to rotate about a braiding spool axis and configured to hold a winding of a multilayer ribbon between a lowermost end and an uppermost end of the braiding spool, wherein the braiding spool axis defines an axial direction;

a bracket to which the braiding spool is rotatably fastened;

a cylindrical additional spool distanced from the braiding spool in the axial direction and configured to wind up a film layer from the multilayer ribbon when the multilayer ribbon is unwound, wherein the additional spool rotates about the braiding spool axis; and

a deflection element fastened to the bracket and positioned at a distance from the braiding spool in a radial direction, wherein the deflection element is configured to deflect the film layer from the braiding spool to the additional spool.

13. The braiding bobbin according to claim 12 wherein the additional spool is directly connected to the braiding spool.

14. The braiding bobbin according to claim 12 wherein:

the deflection element extends in an axial direction from a first deflection element end to a second deflection element end;

the first deflection element end is situated radially outward from the braiding spool; and

the second deflection element end is situated radially outward from the additional spool.

15. A braiding bobbin for a braiding device, the braiding bobbin comprising:

a cylindrical braiding spool configured to rotate about a braiding spool axis and configured to hold a winding of a multilayer ribbon;

a bracket to which the braiding spool is rotatably fastened;

a cylindrical additional spool configured to rotate about the braiding spool axis to wind up a film layer from the multilayer ribbon when the multilayer ribbon is unwound; and

a deflection element fastened to the bracket and positioned at a distance from the braiding spool in a radial direction, wherein the deflection element is configured to deflect the film layer from the braiding spool to the additional spool.

16. The braiding bobbin according to claim 15 wherein:
