Abstract

La invención es una disposición de sellado de un horno de estirado. La disposición comprende un horno de estirado (1) que comprende un orificio vertical central (3) con elementos calentadores circundantes (4) para recibir una preforma de vidrio (2) que comprende una porción ahusada (7) conectada a una varilla de extensión (8). En la parte superior del horno de estirado (1) está dispuesto un sello (5) con una abertura para sellar el interior del horno de estirado (1) del entorno circundante. La disposición comprende un buje anular exterior (16) dispuesto en la parte superior del horno de estirado (1) y un buje anular interior (17) con un primer extremo (18) y un segundo extremo vertical (19) opuesto. El buje anular interior (17) puede posicionarse para rodear al menos parte de la porción ahusada (7), estando el primer extremo (18) situado en la región inicial de la porción ahusada (7) y el segundo extremo (19) comprende protuberancias (22) sobre la superficie exterior. Cuando el buje interior (17) es insertado en el buje exterior (16), el buje interior (17) está dispuesto para ser movible dentro del buje exterior (16) y las protuberancias (22) forman soportes para sujetar el segundo extremo del buje interior (19) por encima del orificio vertical central (3).
