Patent ID: 7959849

Claim:
A method of applying a layer of material to an internal wall of a cycle tyre, in which the tyre has a shape of a torus with an inner wall and an outer wall and includes a crown extended by two sidewalls, two beads, and two bead wires placed in the beads, the tyre having a given nominal inflation pressure, the method comprising: turning the tyre inside out so as to bring the inner wall to face outside of the torus and to bring the outer wall to face inside of the torus; applying an internal inflation pressure above the nominal inflation pressure of the tyre to the outer wall to extend the outer wall while the tyre is turned inside out; applying the layer of the material to the inner wall of the tyre while the internal inflation pressure applied to the outer wall is above the nominal inflation pressure of the tyre; and turning the tyre outside out so as to return the inner wall to face the inside of the torus and to return the outer wall to face the outside of the torus, such that the layer of the material is in a state of compression when the tyre is outside out, and such that the layer of the material stays in the state of compression when the tyre subsequently is inflated to the nominal inflation pressure.
