NEUMATICO RADIAL CON TELA DE CARCASA CON SOLDADURA POR RECUBRIMIENTO OBLICUO

NEUMATICO RADIAL CON AL MENOS UN FLANCO Y UN ARMAZON DE CARCASA CONSTITUIDA POR AL MENOS UNA LAMINA (20) REFORZADA POR HILOS PARALELOS (24), ESTOS DE DIRECCION SENSIBLEMENTE RADIAL, QUE POSEE AL MENOS UNA SOLDADURA POR SOLAPAMIENTO (21) FORMADA POR LA SUPERPOSICION DE DOS EXTREMOS (22, 23) O ELEMENTOS ADYACENTES DE DICHA LAMINA, CARACTERIZADA PORQUE, EN EL CITADO FLANCO, LA ORIENTACION GENERAL D2 DE LA SOLDADURA POR SOLAPAMIENTO ES OBLICUA CON RESPECTO A LA DIRECCION D1 DE LOS HILOS RADIALES (24). EL OBJETO DE LA INVENCION ES EN PARTICULAR UN NEUMATICO RADIAL PARA VEHICULOS TURISMO O CAMIONETAS, CUYA ARMAZON DE CARCASA TIENE UNA SOLA LAMINA RADIAL. LOS HILOS RADIALES (24) SON EN PARTICULAR A BASE DE POLIESTER, PARTICULARMENTE DE POLIETILENO TEREFTALATO. EL NEUMATICO DE LA INVENCION, EN COMPARACION CON LOS NEUMATICOS RADIALES DE TECNOLOGIA ANTERIOR, PRESENTA UN ASPECTO EXTERIOR DE LOS FLANCOS MEJORADO.

Date May 15, 1997A radial tire having at least one side wall and a carcass reinforcement consisting of at least one ply (20) reinforced by parallel threads (24) in substantially radial direction, termed radial threads, and having at least one lap weld (21) formed by superposition of two ends (22, 23) or adjacent elements of said ply, characterized in that, in the side wall, the general orientation (D2) of the lap weld is oblique with respect to the direction (D1) of the radial threads (24). The radial tire for a passenger vehicle or van, has a carcass reinforcement which includes a single radial ply, the radial threads (24) having in particular a polyester, particularly polyethylene terephthalate base. The tire according to the invention, compared to prior art radial tires, presents an improved outward appearance of the side walls.
