Abstract

UN COMPACTO TUBULAR (14) OBTENIDO POR COMPACTACION DE POLVO ES APLICADO CON UNA SUPERFICIE CIRCUNFERENCIAL (16) EN UNA MINIMA DISTANCIA REQUERIDA PARA DICHA APLICACION, DESDE UN EMPOTRAMIENTO (15) QUE CORRESPONDE A DICHA SUPERFICIE CIRCUNFERENCIAL (16). EL ESPACIO ENTRE ENTRE LA SUPERFICIE CIRCUNFERENCIAL (16) Y EL EMPOTRAMIENTO (15) ES EVACUADA, DE TAL FORMA QUE EL COMPACTO (14), MIENTRAS SUFRE UNA CIERTA DEFORMACION PARA PUENTEAR DICHO ESPACIO, ES SUCCIONADO CONTRA EL EMPOTRAMIENTO (15) DE FORMA QUE SE RETENGA FIRMEMENTE CONTRA EL. UN DISPOSITIVO PARA LLEVAR A CABO EL METODO COMPRENDE UN SOPORTE (1) QUE TIENE UN EMPOTRAMIENTO (15) CORRESPONDIENTE A UNA SUPERFICIE CIRCUNFERENCIAL (16) DEL COMPACTO (14), AL MENOS UNA APERTURA (2) PROVISTA EN EL EMPOTRAMIENTO (15) DE LOS MEDIOS DE SOPORTE (1), Y UN CANAL QUE SE DISPONE EN LOS MISMOS (1) Y QUE EN UN EXTREMO COMUNICA CON LA APRETURA (2) EN EL OTRO EXTREMO CONECTABLE (11,12) A UNA FUENTE DE VACIO (13), DE TAL FORMA QUE UNA EVACUACION, LLEVA SOBRE LA FUENTE DE VACIO (13) A TRAVES DEL CANAL Y LA APERTURA (2), DEL ESPACIO ENTRE EL EMPOTRAMIENTO (15) Y EL COMPACTO (16) SUCCIONA EL ULTIMO EN UNA POSICION DE RETENCION FIRME CONTRA EL EMPOTRAMIENTO (15).
