METHOD OF REMOVING A DISMOUNTABLE TOROIDAL SUPPORT FROM A CURED TYRE |
摘要 |
A toroidal support (1) comprises circumferentaillay distributed sectors each having a substantially U-shaped main body and an attachment plate (22) to be engaged between a flange (24) and a counter-flange (25). The conformation of sectors (2a, 2b) enables creation, during vulcanization, of a steam flow licking the whole inner surface of the toroidal support at a short distance from the inner surface of the tyre (5), so that an efficient and homogenous heat transmission is ensured. For removal of the toroidal support (1), each sector, after disengagement of the flange (24) and the counter-flange (25), is extracted from the tyre (5) by a centripetal radial movement combined with angular oscillations around opposite axes (K, K') placed each close to a shoulder region of the tyre (5). Working fluid under pressure can be admitted between the tyre (5) and the toroidal support (1) to cause a preliminary separation of the tyre itself. |
