Abstract
Official abstract text for this publication.
A process for applying particles to the inner wall of a tire comprising two sidewalls, a crown provided radially externally with a tread, a carcass-type reinforcing structure and at least one crown reinforcement, the inner surface of the sidewalls and of the crown forming an inner wall, at least one portion of said inner wall being covered with at least one layer of self-sealing composition. The particles are applied after the curing of the tire.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for applying particles to an inner wall of a tire comprising two sidewalls, a crown provided radially externally with a tread, a carcass-type reinforcing structure and at least one crown reinforcement, an inner surface of the sidewalls and of the crown forming an inner wall, at least one portion of said inner wall being covered with at least one layer of self-sealing composition, comprising applying the particles, after the curing of the tire, to the layer of self-sealing composition by a flocking technique, wherein the particles are comprised of tire grindings. 2. The process according to claim 1 , wherein the flocking technique is carried out by spraying under pressure. 3. The process according to claim 1 , wherein a shape of the particles is defined by a ratio L/E of greater than 3, where L represents the length or largest dimension of the particle and E represents the mean thickness of the particle. 4. The process according to claim 1 , wherein the particles have a mean diameter of between 0.2 and 5 mm. 5. The process according to claim 1 , wherein the particles have any geometric shape. 6. The process according to claim 1 , wherein the particles have a monochromatic yellow colour. 7. The process according to claim 1 , wherein the applied particles establish a particle layer having a mean thickness of between 0.1 and 0.5 mm. 8. The process according to claim 1 , wherein the particles cover between 60% and 95% of the inner wall. 9. The process according to claim 1 , wherein the tire grindings comprise reinforcing threads.
