Abstract: There is disclosed in the present application a cementing apparatus in which a pattern of cement is imprinted upon a part by an imprinting plate which, between imprinting operations, is submerged in a reservoir of cement. A part support, which cooperates with the plate, is shaped to receive the part or workpiece and is movable between loading and imprinting positions. The workpiece is retained by vacuum on the work support and is carried by it into contact with the plate, maintaining register so that the cement pattern is applied in a predetermined position on the workpiece.
