Abstract

EL INVENTO SE REFIERE A UN PROCEDIMIENTO Y UN DISPOSITIVO PARA PRODUCIR CUERPOS HUECOS DE MATERIAL TERMOPLASTICO CUYAS PAREDES SE CONFORMA COMO LAMINADO MEDIANTE MOLDES DE INSUFLADO/EXTRUSION. SE PRODUCE PRIMERO UNA PREFORMA EN FORMA DE TUBO FLEXIBLE CUYAS PAREDES SE CONFORMAN COMO UN LAMINADO PRESENTANDO UN NUMERO DE CAPAS. LA CORRIENTE DE MATERIAL PARA LA FORMACION DE CAPAS LOS LAMINADOS SE CONDUCEN DENTRO DE UNOS CABEZALES EXTRUSIONADORES A TRAVES DE LOS EMBOLOS CIRCULARES SITUADOS EN EL ESPACIO (30) DE ALMACENAMIENTO EN DONDE SE PURIFICA EL LAMINADO. EL CABEZAL EXTRUSOR ESTA EQUIPADO CON UN ESPACIO (30) DE ALMACENAMIENTO EN FORMA ANULAR Y CON UN EMBOLO ANULAR PARA DESCARGAR EL ESPACIO (30) DE ALMACENAMIENTO. LA ANCHURA DE SALIDA PARA LA CORRIENTE DE MATERIAL SE SELECCIONAN LOS EMBOLOS ANULARES, YA QUE ES PROPORCIONAL EL GROSOR DE LA CAPA A FORMARSE AL ESPESOR DEL LAMINADO COLOCADO EN EL ESPACIO DE ALMACENAMIENTO.
