Abstract

LA TOBERA DE RANURA LINEAL SIRVE PARA EXTRUSION DE TERMOPLASTOS Y MUESTRA DOS CUERPOS DE TOBERA LIMITANDO AL MENOS UNA RANURA DE TOBERA, CON LO QUE UNO DE LOS CUERPOS DE TOBERA MUESTRA UN LABIO FLEXIBLE Y UN BLOQUE DE CALENTAMIENTO-ENFRIAMIENTO CON UN ELEMENTO DE CALENTAMIENTO CUYAS VARIACIONES DE LONGITUD GOBIERNAN O REGULAN LA POSICION DEL LABIO FLEXIBLE. EL CUERPO DE TOBERA CON EL LABIO AJUSTABLE TIENE DOS ORIFICIOS LISOS PARA UNA VARILLA ROSCADA. EL BLOQUEO DE CALENTAMIENTO-ENFRIAMIENTO SE ENGRANA CON EL LABIO FLEXIBLE. ENTRE EL CUERPO DE TOBERA DEL LABIO AJUSTABLE Y EL BLOQUE DE CALENTAMIENTO-ENFRIAMIENTO ESTA COLOCADA UNA PIEZA DE TOPE. AMBAS VARILLAS ROSCADAS SE LLEVAN MEDIANTE EL TOPE, CON LO QUE UNA DE LAS VARILLAS ROSCADAS SE ENGRANA CON EL TOPE Y CORRESPONDE CONTRA EL BLOQUE DE CALENTAMIENTO-ENFRIAMIENTO, Y LA OTRA VARILLA ROSCADA CORRESPONDE CON EL BLOQUE DE CALENTAMIENTO-ENFRIAMIENTO, Y LA OTRA VARILLA ROSCADA ENGRANA CON EL BLOQUE DE CALENTAMIENTO-ENFRIAMIENTO Y SU CABEZA DEROSCA SE APOYA EN EL CUERPO DE TOBERA.
