METHOD FOR FORMING A BELT STRUCTURE FOR TYRES OF VEHICLE WHEELS AND RADIAL TYRE INCLUDING SUCH BELT |
摘要 |
During the production of a tyre, a belt structure is formed by means of band-like portions (5) each comprising parallel cords (16) incorporated in an elastomer layer and sequentially laid in a mutually circumferentially adjacent arrangement on a toroidal support (3). According to the invention, the band-like portions (5) are applied with at least one of the smaller sides circumferentially non-aligned with the corresponding smaller side of at least one of the circumferentially adjacent band-like portions (5), so that said cords (16) in the side zones of the belt structure of the radial tyre thus obtained have a non-uniform density. |
