Continuous washing method
摘要:
Method and apparatus for loosening soil from a mass of pervious cloth in which wash solution is applied to the rolls in the form of a plurality of reciprocable cascades to maintain the surfaces of the pervious cloth wet for a time sufficient to saturate the same; excess wash solution is continually drained from the mass of tightly-wound rolls.
