Abstract: A sufficient number of pick-and-place devices (e.g., rolls) whose periods of contact with a substrate are equal or substantially equal to one another are used to form continuous void-free uniform coatings despite the occurrence of unintended or intended coating caliper surges, depressions or voids. The wetted surfaces of the devices contact and re-contact the coating at positions on the substrate that are different from one another. Extremely uniform and extremely thin coatings can be obtained at very high rates of speed. The pick-and-place devices also facilitate drying and reduce the sensitivity of drying ovens to coating caliper surges. Equipment containing the pick-and-place devices is simple to construct, set up and operate, and can easily be adjusted to alter coating thickness and compensate for coating caliper variations.

Abstract: The uniformity of a wet coating on a substrate is improved by contacting the coating at a first position with the wetted surfaces of periodic pick-and-place devices, and re-contacting the coating with such wetted surfaces at positions on the substrate that are different from the first position and not periodically related to one another with respect to their distance from the first position. A coating is applied to a substrate by applying an uneven wet coating, contacting the coating at a first position with the wetted surfaces of periodic pick-and-place devices, and re-contacting the coating with such wetted surfaces at positions on the substrate that are different from the first position and not periodically related to one another with respect to their distance from the first position. These methods can provide extremely uniform coatings and extremely thin coatings, at very high rates of speed. The coatings can be applied in lanes with sharply defined edges and independently adjustable coating calipers.
