Abstract

Perfeccionamientos en dispositivos para la fabricación, por extrusión, de monofilamentos bicompuestos, del tipo de los que comprenden un disco de hileras y un plato de está adaptado para encajar exactamente en el disco de hileras distribución, caracterizados porque la alimentación de los dos polímeros se efectúa a diferentes niveles con respecto al taladro del disco de hileras, prolongándose dicho taladro dentro del plato de distribución en forma de un semicilindro y utilizándose esta última parte para la alimentación de un polímero, mientras que la alimentación del otro polímero se efectúa en la porción del taladro en que éste presenta una sección transversal completamente circular.
