摘要

The device for one-sided coating of flat substrate (4) in a vacuum coating system, comprises a coating source in a coating chamber (1) of the vacuum coating system, and a frame (9) provided with a smooth lower side, a reception opening and an inner profile pointing to the reception opening, where the inner profile is formed equal to an outer profile of the flat substrate insertable into the frame. The flat substrate is insertable into the inner profile of the frame with its rear side in same plane with the lower side of the frame. The frame is movably formed in a continuous coating system. The device for one-sided coating of flat substrate (4) in a vacuum coating system, comprises a coating source in a coating chamber (1) of the vacuum coating system, and a frame (9) provided with a smooth lower side, a reception opening and an inner profile pointing to the reception opening, where the inner profile is formed equal to an outer profile of the flat substrate insertable into the frame. The flat substrate is insertable into the inner profile of the frame with its rear side in same plane with the lower side of the frame. The frame is movably formed in a continuous coating system together with the flat substrate through the vacuum coating system. The frame has a height, which is equal to the thickness of the flat substrate between the coating side and the rear side, and a width at all sides, where the width corresponds to an edge coating width of the substrate, which is determined without frame, with a rear side coating up to highly 1/1000th of the front side coating thickness. The frame is made of flat material, where the height of the frame corresponds to the thickness of the flat substrate between the coating side and the rear side. The frame has a covering part covering the coating side of the narrow edge. The covering part is formed as a separate component, and is connected with the frame in one-piece. The frame adjacent to the lower side is provided with a supporting frame, which engages beneath the flat substrate at the side lying below in a gravitation direction. An independent claim is included for a method for one-sided coating of flat substrates in a vacuum coating system.
