Method and apparatus for applying coating solution

摘要

The present invention provides a method for applying a coating solution by discharging a coating solution from a slit provided at a tip of a slot-die toward a surface of a web fitted onto a backup roller, the method comprising: a stand-by step of staying the slot-die at a stand-by position having a larger clearance between the slot-die and the web than that of a standard coating process; and a two-stage moving operation including a first moving step in which the slot die is moved to a coating initiation position having a smaller clearance than that of the standard coating process to initiate application of a coating solution, and a second moving step in which the slot die is moved away from the coating initiation position to a standard coating position having the clearance of the standard coating process to perform constant application of the coating solution.
