Abstract

Un núcleo para la formación del interior de un artículo cilíndrico hueco provisto de un extremo abierto por el que se sana el núcleo del artículo y de un diámetro interno mayor axialmente hacia dentro del extremo abierto, que comprende un mandril generalmente cilíndrico y un anillo separado montado sobre el mandril para formar el diámetro interno mayor, formándose dicho anillo por la reunión de segmentos ensamblados entre si que no pueden moverse radialmente hacia dentro ni hacia fuera mientras el anillo se halla montado sobre el citado mandril, pero que pueden sacarse individualmente del interior de un artículo formado en torno al núcleo después de haber sacado primeramente dicho mandril, moviendo cada uno de los segmentos radialmente hacia dentro, hacia el centro del articulo, y retirándolo después por el extremo abierto del artículo.
