ABSTRACT:
In a coating head, the configurations of the gap quantity d of a slit, the ejection width w of the slit, etc. are established on the basis of a relational expression in which extremely important factors in practical coating, such as the coating composition viscosity in a reservoir, the pressure loss coefficient of coating composition and the coating composition viscosity in the slit, are taken into consideration, and at the same time, an exchangeable cylindrical shaft is inserted into the reservoir to make the flow resistance in the reservoir controllable.
