Abstract

Método y dispositivo de tratamiento de la extremidad de un tubo plástico para formar un receptáculo de extremidad de tubo en el cual un espacio de tratamiento y moldeo, a través del cual se hace pasar la pared de extremidad ablandada de dicho tubos de plástico, incluye una primera porción inclinada hacia el exterior para ensanchar el radio del tubo mientras la pared de extremidad del tubo avanza, una segunda porción inclinada hacia el exterior dispuesta detrás de la primera porción inclinada hacia el exterior y que ensancha el radio del tubo mientras se desplaza la pared de extremidad del tubo, y una porción inclinada hacia el interior que se extiende a partir de la parte superior de dicha primera porción inclinada hacia el exterior hasta la porción de seno de dicha segunda porción inclinada hacia el exterior y que acorta el radio del tubo mientras la pared de extremidad de tubo avanza, estando dicho método caracterizado porque consiste en: ensanchar la extremidad ablandada del tubo en la dirección circunferencial del mismo en la primera porción inclinada hacia el exterior, estando sometida dicha extremidad del tubo a una fuerza de empuje en su dirección axial, encoger la extremidad de tubo ablandada, que ha atravesado la parte superior de la primera porción inclinada hacia el exterior, en su dirección circunferencial en la porción inclinada hacia el interior para eliminar cualquier deformación parcial de la pared del tubo, aumentar relativamente el espesor de la pared del tubo ablandada en la dirección radial de la misma mientras la extremidad delantera del tubo atraviesa la porción de seno de la segunda porción inclinada hacia el exterior y alcanza su parte superior, y aumentar finalmente el espesor de la pared ablandada del tubo en el espacio de tratamiento y moldeo por medio de la presión de empuje ejercida en esta extremidad del tubo después de pasar a través de la parte superior de la segunda porción inclinada hacia el exterior y después de alcanzar la extremidad finaldel espacio de moldeo.
