A noncompressive dewatering device generates air streams that can be used to remove water from cellulosic webs in an energy efficient manner. Further, a wet-pressed machine can be modified to economically produce low-density tissue with an energy/capital efficiency greater than that of the throughdrying...http://www.google.de/patents/US6096169?utm_source=gb-gplus-sharePatent US6096169 - Method for making cellulosic web with reduced energy input
