METHOD OF MANUFACTURING HOLLOW FIBER FORMED BODY, HOLLOW FIBER FORMED BODY, AND DEVICE FOR MANUFACTURING THE HOLLOW FIBER FORMED BODY

摘要

Disclosed is a method of producing a fiber-molded hollow article by using a papermaking mold ( 2 ) composed of splits ( 21, 22 ) which are joined to form a cavity ( 20 ) having two openings ( 20 a , 20 b) connecting with the outside and an expandable pressing member ( 3 ) adapted to be placed in the cavity ( 20 ). The method comprises the steps of immersing each of the splits ( 21, 22 ) before being joined in a fiber slurry to form a fiber preform ( 10 a , 10 b), joining the splits ( 21, 22 ) each having the fiber preform ( 10 a , 10 b) formed thereon while placing the pressing member ( 3 ) in the cavity ( 20 ), and molding and dewatering a molded article ( 1 ) in the papermaking mold ( 2 ).
