Abstract (en)

[origin: WO9505900A1] A coater incorporates a die (42), a reservoir (46), a gravure cylinder (48), and a doctor blade (50) for applying coating fluid to a moving surface (44). The flow rate of coating fluid to the gravure cylinder (48) is controlled to equal the rate at which coating fluid is consumed by the coating process. This eliminates the need to recycle surplus coating fluid. The coating fluid can be quickly and conveniently replaced with a solvent in the reservoir (46) when coating is not being performed to reduce the occurence of coating defects arising from excessive evaporation of solvent and premature solidification of coating fluid.
