Method for uniformly distributing discrete particles on a moving porous web. |
摘要 |
<p>Method and apparatus for substantially uniformly distributing a layer of discrete particles (10) along a predetermined portion of the uppermost surface of a moving porous web (20) so that the particles (10) occupy less than 100% of the predetermined portion of the uppermost surface of said moving web (20). The method preferably comprises the steps of… (a) entraining the particles (10) into a moving gaseous stream;… (b) passing the gaseous stream through a conduit (7) oriented so as to discharge the gaseous stream containing said entrained particles (10) in a direction substantially parallel to the direction of travel of the moving porous web (20);… (c) mixing the particles (10) entrained in the gaseous stream inside the conduit (7) to provide a substantially uniform distribution of the particles (10);… (d) discharging the gaseous stream containing the uniformly distributed entrained particles (10) from the conduit (7) adjacent the predetermined portion of the uppermost surface of the moving porous web; and… (e) maintaining the fluid pressure adjacent the lowermost surface of the moving porous web (20) at a level lower than that adjacent the uppermost surface of the web (20).</p> |
