涂布装置及涂布方法;COATING APPARATUS AND COATING METHOD

摘要

本发明的课题在于提供一种涂布装置及涂布方法，所述涂布装置是将涂布液涂布于料片的上表面，且可充分提高涂布面的均匀性。本发明是有关于如下的涂布装置，所述涂布装置包括：棒材，经由涂布液与连续移行的料片上表面接触并进行旋转；以及堰板，相对于棒材而设置于料片的移行方向的上游侧，使涂布液穿过所述堰板与棒材之间，并向料片方向流通；且当将堰板与最接近于堰板的棒材的端缘部之间的距离设为A，将堰板与料片之间的距离设为B时，A为0.5mm~5mm，B为0.5mm~5mm，且B≦A。; and a flash board, disposed on a upper stream side of a moving direction of the web with respect to the bar to allow the coating liquid to pass in between the flash board and the bar and flow to a web direction. When a distance between the flash board and an edge of the bar closest to the flash board is set to be A, and a distance between the flash board and the web is set to be B, A ranges from 0.5 mm to 5 mm, B ranges from 0.5 mm to 5 mm, and B ≦
