Title: Coating method and apparatus therefor
Inventor: ISHINISHIKI MAMORU
IPC: B05D1/26
Filed: 1978-12-06
Abstract: PURPOSE: To prevent failures due to stripes generated in the course of coating liquid solidification by a method wherein org. solvent evaporation is controlled by its gas concentration at the interfaces of solid, liquid, and gas phases in the hopper provided at the coating point of channel or bead coating of web.  
     CONSTITUTION: A hood 14 coveres space from the upper block 8 of the hopper 3 to a certain point of the web W which is reversed by the backing roller 2 so that the covered area is nearly of box shape and the covered width has at least the width of the web W. Evaporated gas accumulated and filled in the hood 14 controls, according to gas concentration, org. solvent evaporation at the coating point C and neighbouring three-phase interfaces of solid, liquid, and gas phase. This allows a suddenly formed solid precipitate to be again dissolved by vapor gas in the hood 14 and thus removed or separated from the solid face, thereby quickly preventing stripes from occurring.
