Document Type and Number:
WIPO Patent Application WO/2023/281924
Kind Code:
A1
Abstract:
First, a holding step for holding a tube 31 in a vertically extending direction is performed. Next, a liquid sucking step for sucking up and introducing a coating liquid 32a located in a liquid tank 12 into the tube 31 from the lower end of the tube 31 is performed by using a syringe device 13. Next, a liquid discharge step for forming a state in which the coating liquid 32a adheres in the form of a film to the inner surface of the tube 31 is performed by discharging the coating liquid 32a introduced into the tube 31 from the lower end of the tube 31 by using the syringe device 13. Next, a drying step for forming an inner coating layer 32 on the inner surface of the tube 31 is performed by drying and solidifying the adhered coating liquid 32a with a drying device 14. A coated tube is thus manufactured.
