ABSTRACT:
A coating apparatus for applying a coating on a flexible support which is continuously moving across a die characterized by the die having at least one lip portion with an extrusion slit separating the lip portion into a front blade surface followed by a smoothing blade surface. The improvements are that the smoothing blade surface has a pocket adjacent the slit and an upstream side of the smoothing blade surface lies on a tangent taken at a downstream edge of the front blade surface. The pocket may be formed by a planar surface which separates the slit from a curved surface of the smoothing blade surface or can be formed by the shape of a curved surface of the smoothing blade surface which has the leading or upstream edge disposed inward of the downstream side or edge of the front blade surface. If more than one layer is to be provided, the die has two lip portions which are substantially identical, which portions are spaced apart by a gap so that the first coating can be spaced from the die for a short period of time.
