Document Type and Number:
Japanese Patent JP4366757
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To replace a coating liquid or the like in a short period of time in a coating liquid feed line by installing respective fluid-passages in a cylinder storing a fluid inside and in a piston feeding the fluid to the inside or the outside of the cylinder by reciprocal motion, of a piston pump. SOLUTION: In a die coat method which is used for forming a coating film C on the surface of a material A to be coated such as a glass substrate or the like while a coating liquid 114 delivered out of contact with the surface, a piston pump 120 is used as a feeding means of the coating liquid 114 to a die 30. In order to feed the coating liquid 114 in a tank 112 to the die 30, a piston 128 is travelled to the lower side by a definite quantity and a cylinder 124 is filled in with the coating liquid 114 through a fluid-passage 132, after a taken-in valve 126 is opened and a delivery valve 122 is closed. Then, the piston 128 is travelled to the upper side by a definite quantity and the coating liquid 114 in the cylinder 124 is fed to a manifold 62 of the die 30 through an outlet 136, after the taken-in valve 126 is closed and the delivery valve 122 is opened.
