Flexible adjustable smoothing blade

An apparatus continuously smoothes a wet coating of magnetizable particles and binder on a moving flexible web. A first longitudinal end of a flexible film is held in contact with the wet coating on the substrate and is free to drag against the wet coating. The first longitudinal end is deflected to...

Beschreibung
Zusammenfassung:	An apparatus continuously smoothes a wet coating of magnetizable particles and binder on a moving flexible web. A first longitudinal end of a flexible film is held in contact with the wet coating on the substrate and is free to drag against the wet coating. The first longitudinal end is deflected toward the substrate along a line extending transversely between the first and second transverse ends. The amount of deflection is adjusted and varied during coating to adjust the radius of curvature of the deflection of the first longitudinal end. A smoothing bar or a cylindrical rod, with or without a sharp edge, can hold the flexible film in position. The deflection and adjustment can be performed by a screw. Alternatively, a cylindrical rod is used by itself.
