THE METHOD OF COATING A FLUID HAVING A VISCOSITY OF 1.000 TO 60.000 CPS. ONTO A NONPERMEABLE WEB SUPPORT AT SPEEDS IN EXCESS OF ABOUT 300 FT./MIN. WHICH COMPRISES: (1) FORMING A RIBBON CONTAINING BOTH A LAYER OF THE FLUID COATING AND AN OUTER LAYER OF A FLUID COATING HAVING A VISCOSITY OF 5 TO 50 CPS., (2) SUBJECTING THAT SIDE OF THE RIBBON COMPOSED OF HTE LAYER OF FLUID HAVING A VISCOSITY OF 5 TO 50 CPS. TO A LOWER PRESSURE THAN THE OTHER SIDE OF THE RIBBON, THE DIFFERENCE IN PRESSURE BEING FROM 1 TO ABOTU 10 INCHES OF WATER PRESSURE, (3) CONTACTING THE SIDE OF THE RIBBON COMPOSED OF THE FLUID HAVING A VISCOSITY OF 5 TO 50 CPS. WITH A NONPERMEABLE WEB SUPPORT HAVING AN ELECTROSTATIC POTENTIAL DIFFERENT THAN THAT OF SAID RIBBON, SAID ELECTROSTATIC POTENTIAL DIFFERENCE BEING FROM 800 TO 10.000 VOLTS, AND (4) SIMULTANEOUSLY SUPPLYING THE RIBBON AND MOVING THE WEB SUPPORT ACROSS AND IN CONTACT WITH THE RIBBON.
