Abstract
A coating device for use in coating circular cross-sectioned substrates has a semi-circular doctor blade. The coater may also have a plate for holding axially symmetric substrates which can be rotated about an axis. A groove in the plate centers the substrate on the plate for rotation. The doctor blade is located adjacent to the substrate such that when the plate and substrate are rotated, the doctor blade applies a uniform thickness of coating to one side of the substrate. After one side of the substrate has been coated, the other side is coated by placing the substrate coated side down on a plate with a larger groove to accommodate the increased size of the substrate due to coating.
