Abstract

EL OBJETO DE LA INVENCION ES EVITAR, MEDIANTE LA DISPOSICION DE UN NIVEL DE AGUA MAS ALTO QUE EL BAÑO DE AGUA, LOS INCONVENIENTES QUE SURGEN AL SECAR LA CAMISA DEL CILINDRO DE REFRIGERACION, CONSIGUIENDO CON ELLO EL MAXIMO EFECTO DE REFRIGERACION POSIBLE DE LA PELICULA FUNDIDA. ESTE OBJETO SE CONSIGUE CON UN DISPOSITIVO PARA LA REFRIGERACION DE UNA PELICULA FUNDIDA EXTRUIDA A PARTIR DE UNA BOQUILLA DE RANURA ANCHA EN UN CILINDRO DE REFRIGERACION, EL CUAL COMPRENDE POR LO MENOS UN CILINDRO DE REFRIGERACION GIRATORIO, CUYO EJE DE GIRO ESTA SITUADO DENTRO O FUERA DE UN PRIMER BAÑO DE AGUA CON UN NIVEL DE AGUA, CARACTERIZADO PORQUE TIENE UN SEGUNDO BAÑO DE AGUA (5) CUYO NIVEL DE AGUA (5A) ESTA SITUADO PARCIALMENTE POR ENCIMA DEL NIVEL DE AGUA (4A) DEL PRIMER BAÑO DE AGUA (4).
