Abstract

Un método para la preparación de una boquilla filtrante para cigarrillos que incluye las operaciones de tratar de modo continuo un cordón contínuo de fibras de acetato de celulosa para formar una haz de fibras a modo de velo relativamente abierto someter el haz de fibras a modo de velo y abierto a tratamiento con un producto químico fluido capaz de producir la disolución superficial de la fibra de acetato de celulosa en numerosos puntos al azar a lo largo de las fibras seguir abriendo y esponjando el haz a modo de velo tratado por el fluído hacer pasar el haz de fibras tratadas por fluído a través de un tubo de condensación estrechado para dar un cordón consolidado relativamente densificado pero esencialmente descanalizado y finalmente formar y tratar el cordón descanalizado para formar na varilla estructuralmente unitaria de fibras de acetato de celulosa descanalizadas y en esencia alineadas longitudinalmente que tienen fibras adyacentes soldadas entre sí en puntos arbitrarios de contacto.
