Abstract (en)

When coating liquid is applied to a web (W) in a bar coater while the web (W) is being run, the coating liquid is prevented from becoming solidified to cause a streak failure or result in occurrence of a foreign material adhesion where a solidified material adheres to a coated surface in a gas-liquid-solid interface on an upstream side of a bar (12). A tip end (16A) of an upstream side block (16) is formed in an acute angle and a material of a surface of the tip end (16A) is applied with treatment of any one of DLC, CrN, Hard Cr, and TiAlN, and a surface roughness Ra is set in a range of 1.3 to 5.0 µm.
