Extrusion coating head and coating method for flexible support |
摘要 |
An extrusion coating head comprises an upstream side block (12) and a downstream side block (13) aligned in the conveying direction, and adjusting mechanism. The upstream and downstream side blocks (12, 13) respectively have edge surfaces (12a, 13a) on which the flexible support (1) is pressed. The upstream and downstream side blocks (12, 13) define therebetween a slit (15b) through which a coating composition can be extruded and applied onto the flexible support. The adjusting mechanism adjusts a length (t) of a perpendicular line which is drawn from an upstream end (A) of the edge surface of the downstream side block to a tangential line (L) of the edge surface of the downstream side block which is drawn from a downstream end of the edge surface of the upstream side block, to thereby adjust a distribution of a coating thickness on the flexible support in the width direction.
