Method for applying particles to interior wall of tire of e.g. tourism vehicle moving at high speed, involves covering part of wall, with auto-sealing composition layer, and applying particles after vulcanizing tire to composition layer

摘要

The method involves covering a part of an interior wall with an auto-sealing composition layer (10). Particles (11) are applied after vulcanizing a tire (1) to the auto-sealing composition layer, where the tire comprises sides (3) and a top (2) equipped with a tread that is arranged radially outside a carcass reinforcement structure (7), and a top reinforcement (6). The particles are applied by flocking process, which is carried out by pressurized projection, where the particles have diameter ranging between 0.2 and 5 mm, and an unspecified geometrical form. The particles are selected among organic synthetic fibers, mineral synthetic fibers, synthetic fibers and natural fibers.
