Abstract
Un método de detectar roturas de filamentos de fibra de vidrio que están siendo estirados o extraídos a través de orificios de una placa de orificios, que comprende las operaciones de: disponer un termómetro de radiación de tal manera que una parte de un filamento de fibra de vidrio situada al menos inmediatamente debajo de al menos uno de dichos orificios sea enfocada en el campo de visión de dicho termómetro de radiación; y detectar la variación de la salida de dicho termómetro de radiación cuando, como consecuencia de una rotura del filamento a través de dicho orificio, se desarrolla un glóbulo de vidrio fundido en la superficie inferior de dicha placa de orificios, en dicho campo de visión del citado termómetro de radiación.
