塗布装置、塗布方法および塗膜つき樹脂フィルムの製造方法
Document Type and Number:
Japanese Patent JP6387830
Kind Code:
B2
Abstract:
This coating device comprises: a rotatable coating bar (1) that is arranged inside a container (34) having a coating fluid inlet and an upper opening; a plurality of pairs of rotatable supports (2a, 2b) that are arranged intermittently along the longitudinal direction of the coating bar (1), and that support the coating bar (1) from below; and a weir (37) that is located close to the outer periphery of at least the support (2b). The positional relationship between the support (2b) and the weir (37) is determined such that, if a line that connects the shaft center (13b) of the support (2b) and a point (A) which is the end edge of the weir (37) and which is closest to the support (2b) is defined as a straight line (L1) and if a point where the straight line (L1) intersects with the outer periphery of the support (2b) is defined as an intersection point (B), a straight line (L2) that is perpendicular to the straight line (L1) and that passes through the midpoint of a line segment (AB) does not intersect with the coating bar (1). With this construction, it is possible to suppress ripples on the fluid level inside the container caused by an accompanying flow, and also prevent air bubbles from being entrained and accompanied at the coating section.
