Method and apparatus for liquid coating

In order to enable a material-saving and uniform liquid coating substrates, the invention provides a process for the liquid coating, in which with a laterally goffneten groove (5) and one of the lateral opening (47) of the groove (5) facing surface (91) of a substrate (9) a reservoir (6) is formed, which with fluidem coating material (35) is filled with a gap (7) between the channel (5) and the surface (91) of the substrate (9) remain, and the liquid surface (36 ) of the fluid coating material (35) on the surface (91) of the substrate (9) forms a meniscus (37), and wherein the substrate (9) on the channel (5) or the groove (5) is moved past the Substat (9) along a direction (42) with a vertical component.
