ABSTRACT:
A method for uniformly coating a moving substrate by eliminating nonuniformities in the voscosity of the coating solution along the line where the solution is applied to the substrate. A viscosity-varying region is provided either inside or outside of a coating solution pocket in an extruder assembly. In one embodiment, the voscosity-varying region is provided by making the length of a slit through which the coating solution flows onto the support less than that of the pocket. In another embodiment, the viscosity-varying region takes the form of small-diameter tube through which the coating solution is supplied to one end of the pocket. In a third embodiment, a roller is disposed in the pocket and the diameter of the roller and the pocket are tapered towards the center. In a still further embodiment, the solution is supplied through a distributor.
