Abstract

Perfeccionamientos en dispositivos para rellenar con polvo los intersticios de un cable de conductores múltiples, caracterizados porque se dota a cada dispositivo de: una carcasa cilíndrica; un tubo concéntrico con la carcasa y separado hacia su interior para formar una cámara anular, cuyo tubo se acampana hacia fuera en su extremo de entrada, cerrándose la cámara en cada extremo y desembocando o abriéndose anularmente en el tubo adyacente al extremo de entrada; un dispositivo alimentador de polvo que desemboca en la carcasa; y medios para desplazar el polvo desde la abertura de la carcasa hasta la abertura anular y a través de la misma al interior del tubo.
