Abstract: Acording to embodiements described herein, at least one release agent may be applied onto a cellulosic mixture during production of a cellulosic composite materials. The method for applying the release agent may include supplying a cellulosic mixture comprising a cellulosic fiber and a binder, applying a first release agent onto the top surface of the cellulosic mixture with a first spray, and applying a second release agent onto the top surface of the cellulosic mixture with a second spray, The first spray mayh agitate the top surface of the cellulosic mixture by causing at least some cellulosic fiber material on the top surface of the cellulosic mixture to be displaced. The second spray may substantially coat the entire top surface of the cellulosic mixture.

Abstract: A spraying system may be used for applying a coating fluid onto a cellulosic mixture. The spraying system may include a conveyor and spraying apparatus. The conveyor may include a cellulosic mixture contacting surface and may be moveable in a conveying direction. The spraying apparatus may be operable to deliver coating fluid towards the cellulosic mixture contacting surface. The spraying apparatus may include at least one primary spray nozzle and at least one secondary spray nozzle. Each of the at least one primary spray nozzles may be oriented such that it can deliver the coating fluid in a first spray generally opposite the conveying direction. Each of the at least one secondary spray nozzles may be oriented such that it can deliver the coating fluid in a second spray generally concurrent with the conveying direction.
