Abstract
PURPOSE:To easily and surely form a faucet on a pipe having numerous continuous cavities extending in its wall in the axial direction, by thrusting the end of the pipe into a diameter-increased faucet forming gap to form the end and closing the openings of the cavities on the end of the faucet. CONSTITUTION:An outside mold 12 is moved toward a mandrel mold to define a faucet forming gap 18. A pipe 11 having cavities is held on a holding and thrusting-in unit. The end of the pipe is softened by heat. The pipe 1 is thrusted into the forming gap 18 by the holding and thrusting-in unit so that the pipe is formed. The thickness of the gap 18 is previously set equal to or more than that of the original thickness of the pipe 1 so that the original thickness of the pipe is almost maintained even if the thickness is temporarily reduced due to the increase in the diameter of the pipe. When the diameter of the pipe is increased, the cavities 3 of the pipe are not closed but remain open on the end face of the faucet. However, the end of the pipe is butted against a shaping wall 15 and the pipe is thrusted in further so that the end of the pipe is deformed and the cavities are cloased.
