Abstract

Dispositivo para preparar una mezcla de componentes de plástico químicamente reactivos entreverada con fibras de refuerzo, sobre todo una cabeza de mezcla de una instalación de poliuretano, con una cámara de mezcla (30) para mezclar los componentes de plástico químicamente reactivos, un tubo de salida (36) dispuesto después de la cámara de mezcla (30) en el que está colocado un émbolo de limpieza (37) reversible que presenta un canal central que constituye el tubo de salida (15, 115) de un dispositivo para cortar fibras de refuerzo, con un dispositivo de trasporte con el que se capturan las fibras de refuerzo de un cordón de fibra sin fin y se envían al dispositivo para el corte, caracterizado porque el dispositivo para cortar está constituido por un mecanismo de corte para fibras naturales que presenta un tubo guía (4) para las fibras naturales que con un contratubo de sujeción (10) rodea un canal (5) de sección anular para la alimentación del gas a presión aportado y que ante el extremo del contratubo de sujeción (10) forma una boquilla anular (8), donde el cordón de fibra natural (1) está guiado a continuación sólo por la pieza final del contratubo de sujeción (10) en cuya abertura de salida (9), y transversalmente al eje del contratubo de sujeción (10), hay uno o varios elementos de cuchilla en contacto de cizallamiento con la superficie final del contratubo de sujeción (10) de modo que se pueden mover junto a él, y porque después de los elementos de cuchilla está colocado el tubo de salida (15, 115).
