  • Wet compaction of low density air laid webs after binder application
    Patent number: 4417931
    Abstract: In the manufacture of low density air laid webs of predominantly ligno-cellulosic material, the method and apparatus for bonding the dry web with binder and compacting the web with a wet, fabric covered surface so as to increase tensile strength and delamination resistance while reducing binder content and cost is described. Wet compaction of the binder laden web enables controlled penetration of the web with a smaller amount of binder than is possible without wet compaction, and also reduces energy consumption in drying due to the use of less binder.
