Abstract

EN UN PROCESO DE EXTRUSION DE LAMINAS TUBULARES DE HDPE, QUE SON FABRICADAS CON CUELLOS (12) LARGOS, QUE PARA HOMOGENEIZAR LOS VALORES DE RESISTENCIA Y ESPESOR, SE HA PREVISTO DE FORMA ADICIONAL A LAS TOBERAS (2) ANULARES DEL CABEZAL (1) DE SOPLADO UNA CORONA (7) DE TOBERAS DE AIRE QUE RODEAN EL ANILLO (3) DE SOPLADO EXTERIOR EN LA ALTURA DEL EXTREMO DE LOS CUELLOS (12) LARGOS. LA PRODUCCION DE AIRE A TRAVES LAS TOBERAS (9) DE LA CORONA (7) DE TOBERAS DE AIRE SE CONTROLA EN DEPENDENCIA DE UN DISPOSITIVO (11) DE MEDIDA DE ESPESOR DE LA LAMINA DE FORMA GIRATORIA, QUE SE ENCUENTRA APLICADA FUERA DEL ABOCINAMIENTO (13) DEL ANILLO DE SOPLADO EXTERIOR. LA POTENCIA DE ENFRIAMIENTO DEL ANILLO (3) DE SOPLADO EXTERIOR ES PREFERENTEMENTE DOS VECES MAS GRANDE DE LA CORRESPONDIENTE DE LA CORONA (7) DE TOBERAS DE AIRE. PARA LA ESTABILIZACION DEL SOPLADO DE LAMINA SE HA PREVISTO UN MANDRIL (5) INTERIOR EN LA ALTURA DEL EXTREMO DEL CUELLO (12) LARGO.
