Abstract
La invención se refiere a un procedimiento para la producción de estructuras fibrosas en forma de anillo que consiste en las siguientes etapas: uso de un tejido en forma de una banda (50) formada por dos tramas unidireccionales superpuestas, formando su dirección ángulos opuestos respecto de la dirección longitudinal de la banda, estando las dos tramas unidas mutuamente de manera que forman mallas elementales deformables; bobinado con deformación del tejido para transformarlo en una espiral plana, deformándose las mallas elementales de tal modo que la variación de la masa por unidad de rea entre los diámetros interno y externo de las espiras es limitada, y presión de las espiras planas entre sí.
