Patent ID: 7204903

Claim:
A pressure container manufacturing method for manufacturing a pressure container by forming an outer shell made of a fiber reinforced composite material on an outer periphery of a liner which has a cylindrical portion, dome portions connected to both ends of the cylindrical portion, and a mouth piece disposed on a top of at least one of the dome portions, comprising: forming a body on the periphery of the liner by braiding a fiber bundle provided from a plurality of bobbins of a braider which is disposed in a circumferential direction of the liner, while moving the liner in an axial direction, wherein when a forming position of the body reaches a root portion of the mouth piece of the liner, a movement in a first direction of the liner is stopped, each of the bobbins is rotated approximately a half-turn in the circumferential direction of the liner, and thereafter formation of the body is continued while moving the liner in a second direction opposite to the first direction; and curing a resin which is impregnated in the fiber bundle, to form an outer shell.
