We invested in OptiSizer-Combi with Turn Dry Compact to PM6 at Ebetsu Mill Oji F-Tex Co., Ltd. in April 2013 to have flexible coating operation range. OptiSizer-Combi has a feature of swing machine for pond-sizing and rod metering sizing, and two alternative types of applicator chamber, baffle plate or sealing blade can be selected. The feature of Turn Dry Compact is such excellent performance of non-contact drying system with Air turn that can keep better web runnability. In this paper, we introduce the outline of OptiSizer-Combi and Turn Dry Compact, and describe solutions to problems which we have had during operation such as coating variation due to coating color properties, coating color accumulation onto TDC, coating color overflow over the rod due to excessive applicator chamber pressure.
