Abstract

UNA CABEZA APLICADORA SE SITUA POR DEBAJO DE UN RODILLO DE APOYO SOBRE EL CUAL SE PUEDE EXTRAER UN SUSTRATO. LA CABEZA APLICADORA TIENE UNA CAJA QUE CONTIENE UN DEPOSITO CON MATERIAL DE RECUBRIMIENTO ENTRE UNA TAPA DE SOBREFLUJO SUPERIOR DE LA MAQUINA Y UNA PLANCHA DE EXTRACCION DE LA MAQUINA INFERIOR. EL MATERIAL DE RECUBRIMIENTO FLUYE A UNA DETERMINADA VELOCIDAD EN EL DEPOSITO ADYACENTE A LA TAPA DE SOBREFLUJO. LA PLANCHA PREMEDIDORA SE EXTIENDE RADIALMENTE DESDE LA ABERTURA DE ENTRADA DE RECUBRIMIENTO HASTA UNA POSICION PROXIMA AL RODILLO DE APOYO Y CONVERGIENDO CON EL, DONDE MIDE PREVIAMENTE LA CANTIDAD DE RECUBRIMIENTO APLICADO AL SUSTRATO. LA PLANCHA PREMEDIDORA TIENE PREFERENTEMENTE UNA PLURALIDAD DE AGUJEROS A TRAVES DE LOS CUALES SE EXTRAE EL RECUBRIMIENTO Y EL AIRE. UN ELEMENTO DE MEDICION ESTA COLOCADO CORRIENTE ABAJO DE LA PLANCHA DE PREMEDICION, EXISTIENDO UN AREA DE BAJA PRESION ENTRE AMBAS. EL AIRE Y EL RECUBRIMIENTO SE EXTRAEN DESDE EL AREA DE BAJA PRESION A TRAVES DE UN VALVULA, CONTROLANDOSE ASI LA PRESION.
