Abstract

SE PRESENTA UN PORTACOJINETE EXTRUIDO (10) PARA PRODUCIR CUERPOS DE PLASTICO TUBULARES DE CAPA MULTIPLE EN QUE EL PASO DE FLUJO DE RESINA TUBULAR PARA UNA DE LAS CAPAS DE RESINA POR LO MENOS ES INFINITAMENTE AJUSTABLE EN EL PUNTO DONDE DOS O MAS CAPAS DE RESINA SE UNEN ENTRE SI PARA FORMAR UN CHORRO DE CAPA MULTIPLE. LOS PASOS AJUSTABLES ESTAN FORMADOS DE DOS SUPERFICIES INCLINADAS SEPARADAS EN EL EXTREMO DESCENDENTE DE LOS PASOS. EL GROSOR DE LOS PASOS SE CAMBIA MOVIENDO UNA DE LAS SUPERFICIES AXIALMENTE RESPECTO A LA OTRA. LA SUPERFICIE INCLINADA MOVIL (60) SE ENCUENTRA SOBRE UN MIEMBRO DE ANILLO ANULAR (62) QUE HAY EN EL PORTACOJINETE (10). EN UNA PUESTA EN PRACTICA DE LA INVENCION, EL ANILLO (62) SE PUEDE REEMPLAZAR POR OTRO MIEMBRO DE ANILLO PARA MOVER AXIALMENTE LA SUPERFICIE, AJUSTANDO ASI EL GROSOR DE LA CAPA. EN OTRA PUESTA EN PRACTICA DE LA INVENCION, EL MIEMBRO DE ANILLO (62) SE MONTA DE MANERA ROSCADA EN EL PORTACOJINETE DE MODO QUE CUANDO SE GIRA EL ANILLO SE PRODUCE UN MOVIMIENTO AXIAL DE LA SUPERFICIE PARA AJUSTAR EL GROSOR DE LA CAPA. EN UNA PUESTA EN PRACTICA PREFERENTE DE LA INVENCION UN MECANISMO IMPULSOR QUE SE PUEDE ACCIONAR DESDE EL EXTERIOR DEL PORTACOJINETE HACE GIRAR AL MIEMBRO DE ANILLO PARA PODER REALIZAR EL AJUSTE SIN NECESIDAD DE DESMONTAR EL PORTACOJINETE. EL AJUSTE DEL TAMAÑO DE LOS ESPACIOS EN EL PORTACOJINETE AUMENTA LA GAMA DE GROSORES RELATIVOS DE LAS CAPAS Y AUMENTA LA GAMA DE VALORES DE VISCOSIDAD RELATIVOS QUE PUEDEN SER UTILIZADOS. ASI AUMENTA LA VERSATILIDAD Y UTILIDAD DEL PORTACOJINETE RESPECTO A LOS PORTACOJINETES QUE UTILIZAN ESPACIOS FIJOS.
