Abstract
A wiping cylinder is coated with a synthetic resin plastic composition by rotating the cylinder downwardly past a straight-edge blade on which the plastic composition is supplied so that a thin uniform layer is spread onto the cylinder. The blade is progressively retracted from the cylinder so that successive layers are applied to provide the desired total thickness. Provision is made for first heating and then cooling a layer after it has been applied.
