A coating device, comprising a supply roller having a first contact surface, and a counter-roller placed opposite the supply roller and a second contact surface substantially parallel to the first contact surface. The contact surfaces are at least a substrate width in width and maintain a mutual gap for receiving the substrate therein in contact with both contact surfaces. The supply roller and counter-roller are each rotatable about their central axis. A liquid is supplied to the supply roller. At least the contact surface of the supply roller or the counter-roller is axially adjustable along the central axis thereof. Adjusting means align an edge of the contact surface of the supply roller and the counter-roller with a side of the substrate. An opposite edge of the other of the supply roller and the counter-roller is aligned with an opposite side of the substrate.
