Abstract

ESTA INVENCION SE REFIERE A PERFECCIONAMIENTOS EN LA FABRICACION DE ESTERILLAS DE FILAMENTOS DE FIBRA CONTINUA UTILIZANDO ALIMENTADORES DE FILAMENTOS CONTROLADOS ALTERNATIVOS. MAS PARTICULARMENTE, LA INVENCION SE REFIERE A PERFECCIONAMIENTOS EN LA FABRICACION DE ESTERILLAS DE FILAMENTOS DE FIBRA DE VIDRIO CONTINUA, TENIENDO MAS DENSIDAD UNIFORME MEDIANTE EL CONTROL ELECTRONICO TANTO DEL RITMO ALTERNATIVO COMO DE LA VELOCIDAD A LA QUE LOS FILAMENTOS SE DEPOSITAN SOBRE LA SUPERFICIE DE UN TRANSPORTADOR MOVIL, EN TANTO SE REDUCE TAMBIEN LA VIBRACION ASOCIADA CON LOS ALIMENTADORES. TODAVIA MAS PARTICULARMENTE LA INVENCION SE REFIERE A PERFECCIONAMIENTOS EN LA PRODUCCION DE DOS ESTERILLAS DE FILAMENTOS DE FIBRA DE VIDRIO CONTINUA, TENIENDO UNA PROPIEDADES MECANICAS UNIFORMES EN TANTO QUE LA OTRA TIENE PROPIEDADES DIRECCIONALMENTE DEPENDIENTES. EN LA VERSION PREFERENTE, SE USAN MOTORES DE INDIZACION O DE VELOCIDAD GRADUAL SIN ESCOBILLAS PARA INVERTIR LA DIRECCION DEL MOVIMIENTO ALTERNATIVO DE LOSALIMENTADORES DE FILAMENTOS RAPIDA Y SUAVEMENTE, REDUCIENDO AL MINIMO SU VIBRACION. TAMBIEN SE DISPONE DE MOTORES ELECTRICOS DE VELOCIDAD VARIABLE, JUNTAMENTE CON UN CONTROLADOR LOGICO PROGRAMABLE E INVERSOR DE FRECUENCIAS, PARA AJUSTAR LA VELOCIDAD A LA QUE SE DEPOSITAN LOS FILAMENTOS POR LOS ALIMENTADORES SOBRE EL TRANPORTADOR MOVIL. SE HA REPRESENTADO, A MANERA DE EJEMPLO, QUE ESTOS PERFECCIONAMIENTOS PRODUCEN UNIFORMIDAD AUMENTADA TANTO DE LA DENSIDAD COMO DEL ESPESOR DE LAS ESTERILLAS.
