    摘要: A method of making a water spout (20) from an elliptical preformed tube (24, 26, 28). An outlet end (30) is formed from the tube at the opposite end of a central body portion (38) from an inlet end (34). The central body portion (38) has an arcuate extent of more than ninety degrees and is formed in a roll-forming operation. The method includes forming an outlet trim line edge (46) on the outlet end (30). A U-shaped slot (50) is formed in a lower surface (52). A flange forming tool (58) forms parallel walls (66) and a curved wall (68). A forming tool (70) having a horseshoe shaped cavity operates with a backup die (72) to form the distal end (76) of the outlet end (30) of the tube into an arcuate wall (78). The arcuate wall (78), parallel wall (66) and curved wall (68) flow together and are trimmed to form an aerator trim lip (82) on which a standard aerator is received. The inlet end (34) is formed on one end of an elliptically shaped preform to a round shape. Seal grooves (42) are formed on the inlet end (34) with roll forming tools.
