Abstract

Procedimiento para la fabricación de neumáticos radiales, que comprenden una carcasa radial, una estructura de refuerzo con al menos dos estratos de cords metálicos que constituyen la cintura, cruzados entre sí y orientados simétricamente respecto a la dirección longitudinal del neumático, y una banda de rodaje, cuyo procedimiento comprende las fases de: a) Confeccionar la carcasa en configuración cilíndrica sobre un tambor fundamental de confección expansionable; b) proceder a una primera conformación de la carcasa en el estado no vulcanizado para llevarla a configuración tórica, procedimiento que se caracteriza por el hecho de comprender las fases ulteriores de: c) Disponer y enrollar en configuración cilíndrica la cintura formada por los dos estratos de cords metálicos, sobre un tambor auxiliar expansionable, con un diámetro igual al diámetro exterior de la carcasa después de la primera conformación tórica sobre el tambor fundamental de confección; d) expansionar la parte expansionable del tambor auxiliar y mantener deslizantes en el contacto dichas parte expansionable y cintura, y llevar, en este estado de deslizamiento, la cintura de la configuración cilíndrica inicial a una configuración tórica con desarrollo ecuatorial de valor superior al desarrollo ecuatorial de la carcasa después de la primera conformación; e) contraer el tambor auxiliar; f) extraer del tambor auxiliar el paquete anular que comprende la cintura y la banda de rodaje enrollada sobre aquella después de la fase d); g) transferir y centrar este paquete anular en correspondencia del plano ecuatorial de la carcasa sobre el tambor fundamental; h) expansionar el tambor fundamental y proceder a una segunda conformación tórica de la carcasa hasta llevar la corona de la misma a contacto con la correspondiente superficie tórica de la cintura, e i) vulcanizar en molde bajo presión el neumático formado de esta manera.
