Abstract

Perfeccionamientos en los aparatos de entrega de artículos tales como hilos, cintas y similares, particularmente para entregarlos positivamente bajo una tensión aproximadamente constante en función de la acción de recogida ejercida por una máquina de utilización, del género que comprende, por una parte, un sistema de movimiento del hilo mandado por un motor de velocidad regulable, por otra parte un sistema tensor constituido por órganos de reenvío tales como poleas, ojetes o análogos, llevados por dos soportes móviles forzados elásticamente a alejarse el uno del otro, pasando el hilo en zigzag entre estos órganos del uno y del otro soporte, mientras se prevén medios de control de la velocidad del motor en función de la posición relativa de dichos soportes de manera que la velocidad de entrega del hilo aumente a medida que se acerquen y disminuya a media que se alejen, caracterizados porque los órganos de reenvío (7b) están soportados por los soportes móviles (1) mediante pequeños brazos (7a) de masa muy reducida forzados elásticamente en el sentido correspondiente a la tensión del hilo (11).
