Abstract

Un aparato mejorado para formar fibras de vidrio del tipo que tiene una placa de orificios con una multiplicidad de orificios muy juntos y una cara inferior plana, medios para estirar hacia abajo conos de vidrio formados bajo dichos orificios para convertirlos en fibras de vidrio, y medios para soplar aire de enfriamiento contra la cara inferior de dicha placa de orificios, caracterizado por el perfeccionamiento que comprende medios para separar una masa de vidrio fundido adherida a la cara inferior de dicha placa de orificios en estado reunido para formar fibras individuales, comprendiendo dichos medios separadores un vástago estacionario y alargado que se yergue sobre el suelo, espaciado por debajo de dicha placa de orificios en una posición fuera de la corriente de fibras de vidrio y extendiéndose hacia dicha placa de orificios, un portador móvil a lo largo de dicho vástago, medios montados en dicho portador para coger de modo soltable dicha masa de vidrio fundido, y unos medios de accionamiento para hacer subir y bajar dicho portador a y desde una posición que permita que dichos medios agarradores alcancen dicha masa de vidrio fundido.
