Claim 1
Independent Claim
169 words
THE METHOD FOR CONTINUOUSLY WASHING A MINERAL FIBERCOLLECTING FORAMINOUS CONVEYOR WITH WATER AND REUSING SAID USED WASH WATER IN THE PREPARATION OF BINDER FOR APPLICATION TO THE MINERAL FIBERS AT A PLURALITY OF FIBER-FORMING STATIONS INCLUDING THE STEPS OF FEEDING AN ALKALINE DETERGENT INTO THE USED WASH WATER CONTAINING WASTE BINDER TO RAISE THE PH TO AN ALKALINE LEVEL, DIVIDING THE DETERGENTTREATED WASH WATER INTO PORTIONS, WASHING THE CONVEYOR WITH ONE PORTION OF THE DETERGENT-TREATED WASH WATER TO REMOVE WASTE BINDER THEREFROM, DIRECTING ANOTHER PORTION OF THE DETERGENT-TREATED WASH WATER TO A BINDER PREPARING STATION, MIXING BINDER INGREDIENTS WITH THE DETERGENTTREATED WASH WATER AT THE BINDER PREPARING STATION, FEEDING AN ACIDIC NEUTRALIZING AGENT COMPATIBLE WITH THE BINDER INTO THE WASH WATER FOR PREPARATION OF THE BINDER TO REDUCE THE ALKALINITY TO A PH OF SUBSTANTIALLY 7, SPRAYING THE BINDER MIX ONTO THE FIBERS AT THE FIBER-FORMING STATIONS, AND ADDING FRESH WATER TO THE USED WASH WATER SUFFICIENT IN AMOUNT TO MAINTAIN SUBSTANTIALLY CONSTANT THE TOTAL VOLUME OF WASH WATER.
