Abstract

SE FORMA UNA PRIMER PLIEGUE DE LA CARCASA (3) DEPOSITANDO SOBRE UN SOPORTE TOROIDAL (11), LONGITUDES EN FORMA DE TIRAS (13) CORTADAS CON EL TAMAÑO ADECUADO DE UN ELEMENTO CONTINUO EN FORMA DE TIRA Y CADA UNO DE LOS CUALES COMPRENDE ELEMENTOS LONGITUDINALES EN FORMA DE BANDA DE RODADURA (14) INCORPORADOS EN UNA CAPA DE MATERIAL ELASTOMERICO (17). LAS LONGITUDES EN FORMA DE TIRA SE DISPONEN SECUENCIALMENTE EN UNA RELACION MUTUA CIRCUNFERENCIAL, LADO CONTRA LADO, PARA FORMAR PARTES LATERALES (25) PARCIALMENTE SUPERPUESTAS ENTRE SI Y PARTES DE CORONA (24) EN UNA RELACION CIRCUNFERENCIAL MUTUA LADO CONTRA LADO. ASOCIADAS CON EL PLIEGUE DE LA CARCASA (3) SE ENCUENTRAN ESTRUCTURAS ANULARES (4) QUE COMPRENDEN UN PRIMER Y UN SEGUNDO INSERTO ANULAR CIRCUNFERENCIALMENTE INEXTENSIBLES (27, 28) Y UN RELLENO ELASTOMERICO (29) DISPUESTOS ENTRE LOS MISMOS. UN SEGUNDO PLIEGUE DE CARCASA (31) SE HACE EN UNA POSICION SUPERPUESTA CON RESPECTO AL PRIMER PLIEGUE DE LA CARCASA (3) Y LAS ESTRUCTURAS ANULARES (4).UNA ESTRUCTURA DE CORREA (5), UNA BANDA DE RODADURA (8) Y LAS PAREDES LATERALES (9) SE COMBINAN CON LA ESTRUCTURA DE CARCASA (2) ASI FORMADA, PARA DEFINIR EL NEUMATICO (1) A SER VULCANIZADO.
