Abstract

Para enrollar un material de tira de caucho alrededor de un cilindro de formacion, se enrolla espiralmente un material S de tira de caucho extruido desde una boquilla 2 de un extrusor 1 por un aplicador 6 y se forma alrededor del cilindro 5 de formacion en tanto que se esta girando. En la operacion de formacion, la velocidad periferica Vd el cilindro 5 de formacion se ajusta para ser menor que la velocidad de extrusion Ve del material S de tira de caucho desde la boquilla 2 del extrusor 1, es decir, a una velocidad periferica de 0.6 a 0.95 veces la velocidad de extrusion Ve y de manera preferente a una velocidad periferica de aproximadamente 0.9 veces la velocidad de extrusion Ve. Con este arreglo, el material de tira de caucho estirado por el hinchamiento de la boquilla se puede contraer, se puede formar un miembro estructural y neumatico alrededor del cilindro de formacion con alta exactitud en todo momento independientemente de la clase del material de tira de caucho, y se puede mejorar la capacidad de trabajo asi como la estabilidad de forma despues de que se forma el material de tira de caucho.
