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.
摘要:
A method and machine for applying an interconnected series of flat sheet-formed pour spouts with integral bands individually to a series of containers.
摘要:
This machine for punching, cutting and shaping pouring spouts from a metal band for miscellaneous packings comprises essentially a single shaft, connected through a bevel gear to the driving motor of the packing machine, for performing the various operations, including punching a preferably square-shaped hole engageable by a pin for feeding the metal band through the machine, such pin being pivotally mounted and driven with a horizontal reciprocating motion. Punch and die means are operated for cutting portions of the band for permitting the subsequent folding of the side wings of the spout. Other means are provided for punching into the band projecting lugs to be used for securing the spout to the packing.
