Abstract

ESTA INVENCION SE REFIERE A UN APARATO DE COEXTRUSION PARA VARIAR EL PERFIL EXTERNO DEL EXTRUDADO (19) QUE ESTA FORMADO POR UNA CORRIENTE DE MATERIAL ELASTOMERO EXTERNO Y OTRA CORRIENTE INTERNA MEDIANTE LA VARIACION (45) DE LA ABERTURA TERMINAL ANULAR DE UNA BOQUILLA ELASTICA (45) QUE VARIA EL TAMAÑO DEL ORIFICIO DE EXTRUSION EXTERNA Y CONSECUENTEMENTE DEL FLUJO DE LA CORRIENTE EXTERNA DE MATERIAL ELASTICO QUE SE DEPOSITA EN LA SUPERFICIE EXTERNA DEL EXTRUDADO TABULAR. UN PISTON HIDRAULICO ESTA MONTADO DE MANERA DESPLAZABLE AXIALMENTE PARA SU UNION CON LA BOQUILLA ANULAR ELASTICA Y TIENE UNA ABRAZADERA QUE SE MUEVE A LO LARGO DE LA SUPERFICIE EXTERNA DE LA BOQUILLA ELASTICA PARA VARIAR EL TAMAÑO DEL ORIFICIO DE EXTRUSION EXTERNA Y CONSECUENTEMENTE LA CANTIDAD DE MATERIAL ELASTICO QUE SALE A SU TRAVES. UN DETECTOR DE MOVIMIENTO LINEAL (65-69) ESTA CONECTADO AL PISTON PARA DETECTAR LA CANTIDAD DE MOVIMIENTO LINEAL DEL PISTON Y SUMINISTRAR SEÑALES DE CONTROL PARA CONTROLAR EL MOVIMIENTO DEL PISTON. EL ORIFICIO DE LA CORRIENTE INTERNA DEL MATERIAL ELASTICO ESTA LOCALIZADO UN POCO MAS ARRIBA DEL ORIFICIO DE LA CORRIENTE EXTERNA DE MATERIAL ELASTICO Y ES NORMALMENTE FIJO. UNA GUIA REINFORZADA (14) DIRIGE UN NUMERO DE ELEMENTOS DE REFUERZO DE FIBRA (15) EN EL EXTRUDADO TABULAR GENERALMENTE EN LA UNION DE LAS CORRIENTES EXTERNAS E INTERNAS DEL MATERIAL ELASTICO. TAMBIEN SE DESCRIBE UN METODO PARA VARIAR EL PERFIL EXTERNO DEL EXTRUDADO TABULAR.
