Abstract

PURPOSE: Liquid synthetic resin material of which viscosity and volume may rapidly be varied in response to its reaction is discharged uniformly to a desired wide width without any splash at all by mixing the resin material having two or more constituents under a specified pressure and condition.
CONSTITUTION: The valve 8 is placed on a dotted line in the hollow cavity 6 and the liquid synthetic resin materials P1 and P2 in the tank T are circulated by the pump via change-over mechanism 2. Air is fed to the air supply port 14 to move the leading end of the valve 8 from the dotted line position in the hollow cavity 6 to the solid line position therein, the change-over mechanism 2 is set to the adapter 4, the materials P1 and P2 are supplied to the injection port 7 of small diameter, injected up to the upper end of the hollow cavity 6 to make their mixed condition and charged in the hollow cavity 6. Thereafter, the plate material 11 having a smooth surface is used to shut off the materials at the lower end 6b of the hollow cavity 6 to change a flow of the mixture P along the smooth surface 10a of the plate material 11, a crescent-shaped form from the inclined port 10 along the surface of the smooth surface 10 of the plate material 11 and gradually made to form a film layer and supplied to the metal plate A.
