Abstract

Claims (35)

1. An assembly comprising:

a first structure formed by first filamentary elements, the first structure having a longitudinal edge extending in a first direction which defines a first axis;

a second structure formed by second filamentary elements, the second structure having a longitudinal edge extending in a second direction which defines a second axis; and

a supporting structure comprising supporting filamentary elements linking the first filamentary elements of the first structure and the second filamentary elements of the second structure, wherein the supporting filamentary elements of the supporting structure are interlaced with the first filamentary elements and the second filamentary elements,

wherein the assembly further comprises at least one filamentary securing element interlaced with the first filamentary elements and the second filamentary elements, the at least one securing element having a first end and a second end, and at least one of the first and the second ends of the at least one securing element being free to slip relative to the first filamentary elements and the second filamentary elements,

wherein the first axis and the second axis are parallel, and

wherein the at least one securing element is arranged so that, when the first structure and the second structure are separated from one another so as to tauten without breaking the supporting filamentary elements, at least one of the first end and the second end of the at least one securing element slips relative to the first filamentary elements and the second filamentary elements without causing the at least one securing element to break.

2. The assembly according to claim 1 , wherein the at least one securing element is arranged so that, when the first structure and the second structure are separated from one another, at least one of the first end and the second end of the at least one securing element slips relative to the first filamentary elements and the second filamentary elements.

3. The assembly according to claim 1 , wherein the first axis and the second axis are superposed.

4. The assembly according to claim 1 , wherein the first structure and the second structure each comprise a transverse edge extending at right angles to the respective longitudinal edge, and

wherein the transverse edge of the first structure and the transverse edge of the second structure are superposed.

5. The assembly according to claim 1 , wherein the first end and the second end of the at least one securing element are free to slip relative to the first filamentary elements and the second filamentary elements.

6. The assembly according to claim 1 , wherein the first structure has two opposing transverse edges extending transversely to the longitudinal edge, a length of the first structure being equal to a shortest distance between the two opposing transverse edges when the first structure is placed on a flat surface, and

wherein the at least one securing element extends over all or part of the length of the first structure.

7. The assembly according to claim 1 , wherein the at least one securing element extends in a third direction which defines a third axis, an angle between the third axis and the first axis being non-zero.

8. A method for manufacturing an assembly according to claim 1 , the method comprising the following steps:

placing the first structure on the second structure so that the first axis and the second axis are substantially parallel, and

fixing the first structure on the second structure by interlacing the at least one securing element with the first filamentary elements and the second filamentary elements so as to hold the first structure in position relative to the second structure, one of the first end and the second end of the at least one securing element being left free to slip relative to the first filamentary elements and the second filamentary elements.

9. The method according to claim 8 , further comprising, after fixing the first structure on the second structure, separating the first structure and the second structure from one another, during which at least one of the first end and the second end of the at least one securing element slips relative to the first filamentary elements and the second filamentary elements.

10. The method according to claim 9 , wherein, while separating the first structure and the second structure from one another, at least one of the first end and the second end of the at least one securing element slips relative to the first filamentary elements and the second filamentary elements without causing the at least one securing element to break.

11. The method according to claim 8 , further comprising, prior to fixing the first structure on the second structure, superposing the first axis and the second axis.

12. The method according to claim 8 , wherein the first structure and the second structure each comprise a transverse edge extending transversely to the respective longitudinal edge, the method further comprising, prior to fixing the first structure on the second structure, superposing the transverse edge of the first structure and the transverse edge of the second structure.

13. The method according to claim 8 , wherein the first structure has two opposing transverse edges extending transversely to the longitudinal edge, a length of the first structure being equal to a shorter distance between the transverse edges when the first structure is flat, and the first structure being fixed over all or part of its length onto the second structure.

14. A tire having an axis of revolution and comprising:

an assembly manufactured according to claim 8 ; and

an annular space delimited radially by an inner face of the first structure and by an inner face of the second structure.

15. An assembly comprising:

a first structure formed by first filamentary elements, the first structure having a longitudinal edge extending in a first direction which defines a first axis;

a second structure formed by second filamentary elements, the second structure having a longitudinal edge extending in a second direction which defines a second axis; and

a supporting structure comprising supporting filamentary elements linking the first filamentary elements of the first structure and the second filamentary elements of the second structure,

wherein the assembly further comprises at least one filamentary securing element interlaced with the first filamentary elements and the second filamentary elements, the at least one securing element having a first end and a second end, and at least one of the first and the second ends of the at least one securing element being free to slip relative to the first filamentary elements and the second filamentary elements,

wherein the first axis and the second axis are parallel,

wherein the first structure and the second structure are separated by a space, the space consisting of at most the supporting structure and the at least one filamentary securing element, and

wherein the at least one securing element is arranged so that, when the first structure and the second structure are separated from one another so as to tauten without breaking the supporting filamentary elements, at least one of the first end and the second end of the at least one securing element slips relative to the first filamentary elements and the second filamentary elements without causing the at least one securing element to break.

16. The assembly according to claim 15 , wherein the space has a variable volume depending on a quantity of air injected between the first structure and the second structure.
