Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA MEDIR LA POROSIDAD DE LOS PAPELES USADOS EN LA FABRICACION DE CIGARRILLOS. SOBRE UN AREA PREFIJADA DE MATERIAL SE DIRIGEN UNA SERIE DE FLUJOS CON DIFERENTES CAUDALES. UNOS MEDIDORES DE LA DIFERENCIA DE PRESION ENTRE LAS CARAS DEL MATERIAL ACCIONAN A UNOS ORGANOS QUE CONTROLAN LOS ELEMENTOS QUE GENERAN Y TRANSPORTAN LOS FLUJOS, DETERMINANDOSE LA POROSIDAD DEL MATERIAL EN BASE A LAS DIFERENCIAS DE PRESION MEDIDAS EN DOS CASOS DIFERENTES. UNO, EN EL QUE UN JUEGO DE FLUJOS DA UNA DIFERENCIA DE PRESIONES MENOR QUE LA QUE RESULTARIA DE CUALQUIER OTRO JUEGO, Y OTRO, EN EL QUE UN SEGUNDO JUEGO DE FLUJOS DA UNA DIFERENCIA DE PRESIONES MAYOR QUE LA QUE RESULTARIA DE CUALQUIER OTRO JUEGO.
