Abstract
EN UN ELEMENTO DE CABEZA (11) SE SUJETA UNA ESPINA (15) EN UN PASO (13), POR MEDIO DE UN BRAZO. EN LA ESPINA SE ENCUENTRA UNA PERFORACION (29) PARA ALBERGAR UNA BARRA REGULADORA DESPLAZABLE AXIALMENTE (27). CON LA REFERIDA BARRA (27) EL NUCLEO (21) PUEDE QUEDAR EN FORMA AXIAL EN RELACION CON LA BOQUILLA. DICHA POSICION PERMITE GRADUAR LA SOLIDEZ DE LOS LADOS DEL TUBO EXTRUSIONADO. LA VELOCIDAD DE EXTRUSIONADO PUEDE QUEDAR REGULADA POR MEDIO DEL TORNILLO DE ESTRANGULACION (39). LA FUSION SE DIRIGE POR MEDIO DEL CANAL DE CONDUCCION DEL PRODUCTO FUNDIDO A LOS DIVERSOS PASES (13) (EN LA FIGURA SOLO ESTA REPRESENTADO UNO DE ELLOS). POR MEDIO DEL REPARTIDOR DE CORRIENTE (43) LA CORRIENTE DE FUSION QUEDA REPARTIDA. CON LO CUAL, UNA PARTE DE LA MASA FUNDIDA SE IMPULSA HACIA ABAJO, HACIA EL PASO (13), MIENTRAS QUE LA FUSION RESIDUAL PUEDE FLUIR HACIA LOS PASOS PROXIMOS (13). LA FUSION QUE CIRCULA HACIA EL PASO (13) APENAS QUEDA OBSTACULIZADA, POR EL BRAZO (17) Y SALE POR LA TOBERA (33) PARA FORMAR UN FRAGMENTO DE TUBO.
