Abstract
A wet gravure coating of fine magnetizable particles can be smoothed by a rectangular piece of flexible film that is secured at one end in flat jaws of a clamp to leave its opposite end free to drag against the coating, thus causing the flexible film to form an arc between its secured end and the convergence of the flexible film with the wet coating. The jaws also secure a flat plate which has a straight edge that deflects the arcuate portion of the flexible film toward the coating along a line extending transversely across the full width of the flexible film. The plate can be repositioned during the smoothing to adjust the radius of curvature of the arc in order to correct any defects that may appear in the smoothed coating. When the backing web is wide and is advanced at economically high speeds, the free end of the flexible film can be tensioned so that its trailing edge becomes bowed and in contact with the coating over its full width.
