摘要:
The coating apparatus and method enable the coating liquid having been scraped-off to be reused without doing any one of the fluid adjusting treatment and the filtering treatment, while maintaining the features of the scraping-off type of extrusion coater, which is suitable for obtaining a uniform and extremely thin coating film. The coating head is provided with two slits: a coating slit and a recovering slit, and the excessive coating liquid having been discharged through the coating slit and applied to the web is scraped-off and recovered through the recovering slit.
摘要:
It is possible to give ultrathin and uniform coating on a flexible web in scraping-off type coating. The distribution of pressure in a web width direction is adjusted by a pressure distribution adjusting device when an excess of coating liquid excessively applied is scraped off by a doctor blade by giving relative pressure to a coating surface of a web and the doctor blade after applying the coating liquid that is more excessive than the desired quantity of the coating liquid on the web by a precoating apparatus while making the web continuously travel.
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.
