Problems solved by technology

Now, when handling assemblies, it is commonplace for one structure to slide relative to another, so the supporting structures are not tensioned to prevent their relative movement

Embodiment Construction

[0048] component 1

[0049] Component 1 includes:

[0050] - a first structure 10 formed by a filamentary element,

[0051] - a second structure 12 formed by a filamentary element,

[0052] - A supporting structure 14 comprising supporting filiform elements connecting the first structure 10 and the second structure 12 .

[0053]Examples of assemblies 1 comprising these three structures 10 , 12 , 14 and which can be used have been described in detail, for example, in the aforementioned documents WO 2017 / 103490 and WO 2017 / 103491.

[0054] More specifically, the first structure 10 is generally trapezoidal (for example, parallelepiped or rectangular), and has a first longitudinal edge 10a, a second longitudinal edge 10b opposite to the first longitudinal edge 10a, and two The opposite transverse edges 10c, 10d, the first longitudinal edge 10a extending in a first direction defining a first axis 11, said two opposite transverse edges 10c, 10d being transverse to the first lon...

Abstract

The invention concerns a method for manufacturing (S) a sub-assembly (3) for a tyre (4) comprising the following steps: providing an assembly comprising a support structure (14) comprising supportingthread-like elements linking a first structure (10) of thread-like elements and a second structure (12) of thread-like elements, aligning (S1) the first structure (10) and the second structure (12), securely attaching (S4) the first structure (10) to the second structure (12) using a securing element (18), and cutting (S5) the assembly (1) along the securing element (18) in such a way as to separate said securing element (18) from the rest of the assembly (1) and obtain at least one subassembly (3) not containing a securing element (18).

Description

technical field [0001] The present invention relates generally to the field of tires for vehicles, typically personal passenger vehicles, two-wheeled vehicles, heavy trucks, agricultural or civil engineering vehicles or aircraft, or more generally for any rolling gear. More specifically, the invention relates to the flattening of such tires. Background technique [0002] The tire 4 is a ring-shaped structure intended to be mounted on a rim, pressurized by inflation gas and flattened on the ground under load. [0003] As shown in the example of tire 4 figure 1 As can be seen in , the tire 4 has a running surface (ie, the surface intended to be in contact with the ground), a running plane (ie, a plane perpendicular to the axis of rotation YY' and intersecting the running surface), a circumference Axial axis XX' (which corresponds to the axis of the running plane tangential to the running surface) and a radial axis Z-Z' (which corresponds to the axis transverse to the axis of...
