Abstract

EN LOS DISPOSITIVOS CONOCIDOS DE IMPREGNACION A PRESION, UNA CAMARA QUE SE ESTRECHA DE FORMA CONTINUA EN LA DIRECCION DE TRANSPORTE ESTA LOCALIZADA ENTRE UN RODILLO RODEADA POR LA BANDA A SER IMPREGNADA Y LA PARED INTERIOR DE UN RECIPIENTE QUE CONTIENE EL MEDIO DE IMPREGNACION. EL MEDIO DE IMPREGNACION SE SUMINISTRA A LA CAMARA BAJO ALTA PRESION, Y LA PRESION ES ADEMAS INCREMENTADA EN LA CAMARA MEDIANTE EFECTOS DINAMICOS. LA PRESION ALTA ORIGINA PROBLEMAS DE ESTANQUEIDAD EN LAS RANURAS DE ENTRADA Y SALIDA, ASI COMO EN LA CARA FRONTAL DEL DISPOSITIVO. LAS APLICACIONES DE ESPONJAMIENTO APLICADAS POR LA BANDA DE PAPEL Y EL MEDIO DE IMPREGNACION QUE PENETRA EN LAS SUPERFICIES DE DESLIZAMIENTO PUEDE PERTURBAR LA OPERACION DEL DISPOSITIVO. EL OBJETIVO DE LA INVENCION ES RESOLVER ESTOS INCONVENIENTES. EL NUEVO DISPOSITIVO TIENE APLICACIONES DE SELLADO CON RANURAS (12,23,24) ANCHAS Y ESTRECHAS DE MANERA ALTERNATIVA, EN FORMA DE SELLADO LABERINTICO. LAS RANURAS (12,23,24) ESTAN PROVISTAS CON SALIDAS(14,15,26) PARA EL MEDIO DE IMPREGNACION QUE FLUYE A TRAVES DE LAS RANURAS.
