PROCESS FOR COATING STRIP-FORM SUBSTRATES |
摘要 |
A method of coating a strip of viscous solution on a movable substrate by feeding the coating solution through a narrow gap between coating apparatus which includes feed means and the movable substrate under a static pressure differential between the inlet and the outlet of the gap wherein the gap is part of a coating chamber of the coating apparatus. The gap is wider than the wet formed layer after formation. The coating chamber is connected to a vacuum means at the side of the coating from which the substrate is introduced. A negative pressure is effectuated at the inlet side of the coating apparatus. The vacuum means having a vacuum which seals the inlet end of the narrow gap in the coating apparatus by sucking air from the vacuum means through a diaphragm which withdrawal is at a uniform rate of flow.
