Abstract

Un método de fabricar un tubo de rayos catódicos que comprende una envuelta tubular de vidrio que está herméticamente cerrada en un extremo por una ventanilla que lleva un blanco en su superficie interna , estando dispuesto un electrodo dentro de dicha envuelta y delante del blanco, caracterizado porque la envuelta se obtiene succionando sobre un mandril una porción de tubo de vidrio que es reblandecida por calentamiento, las dimensiones transversales de cuyo mandril cerca de un extremo de la porción de tubo aumentan en la dirección del extremo al menos el doble en esencia de manera escalonada, de modo que en la dirección del extremo, tras la succión, al menos unas porciones de pared primera y segunda de la superficie interna de la porción de tubo quedan dispuestas en planos que son transversales al eje longitudinal del tubo, cuya primera porción de pared sirve de superficie de aplicación para la ventanilla.
