Apparatus and method for coating a portion, in particular a chamfer and/or an end face, of a planar workpiece with a coating medium

Abstract

The present invention relates to an apparatus (1) for coating a portion, in particular a chamfer and/or an end face, of a planar workpiece with a coating medium, the apparatus comprising a coating unit (2) which has an application device (3) and a blow-off device (4) which are arranged such that the portion of the workpiece to be coated can be moved along first to the application device (2) and then to the blow-off device (3), wherein a negative pressure can be generated in a negative pressure region (8) of the coating unit (2), wherein the application device (3) has a coating medium supply (9) for supplying the coating medium to an application region (10) in which the coating medium can be applied to the portion of the workpiece by means of the negative pressure in the negative pressure region (8), wherein the blow-off device (4) has at least one blow-off nozzle (13) through which a gas, in particular air, can be blown onto the workpiece in order to blow applied coating medium off the workpiece into the negative pressure region (8) and thereby adjust a layer thickness of the coating medium on the workpiece, wherein the blow-off device (4) has an air intake opening (14) through which additional air from outside the coating unit (2) can flow in during blowing using the blow-off nozzle (13) in order to generate an air flow between the workpiece and the negative pressure region (8) and to reduce unwanted deposits of coating medium on the workpiece.
