Abstract
1. Un método de formar el extremo de campana de un tubo de plástico, comprendiendo dicho método: calentar una sección extrema de dicho tubo hasta el estado de deformabilidad térmica de la misma; formar a partir de dicha sección extrema calentada una parte axial diametralmente agrandada y una pared extrema transversal que une dicha parte agrandada con el resto de dicho tubo; después de formar dicha parte agrandada, engrosar de manera sustancialmente uniforme su configuración en sección transversal reduciendo su longitud; al tiempo que se engrosa la configuración en sección transversal de dicha parte agrandada, formar de manera enteriza medios de nervio que sobresalen hacia fuera en la superficie interior de dicha pared extrema transversal, estando dichos medios de nervio situados radialmente hacia fuera desde la superficie interior de dicha parte agrandada con el fin de definir un espacio entre ellos; posicionar concéntricamente una junta de obturación circunferencial dentro de dicha parte agrandada y contra dicha pared extrema de tal modo que un segmento extremo de dicha parte agrandada se extienda más allá de dicha junta, estando configurada dicha junta de tal manera que partes de la misma estén situadas dentro de dicho espacio; y deformar radialmente hacia dentro dicho segmento extremo con el fin de bloquear a dicha junta de obturación en posición.
