  • Thermoplastic container forming method
    Patent number: 4717523
    Abstract: Apparatus and method are provided for straightening a parison tube (58b) in an apparatus of the type in which thermoplastic tubing (48) is extruded into open halves (24 and 26) of a blow mold (22) and a parison tube (58b) is severed from the thermoplastic tube (48) concurrently with the blow mold being rotated around an axis (28). The present invention orients the curvature of the parison (58b) in a predetermined plane (52) by accelerating the parison tube (58b) transversely to the axis (90) of the parison tube (58b); and then the parison tube (58b) is straightened by applying jets of air (76) against the neck and moil portion (68) of the parison tube (58b), thereby straightening the parison tube (58b), and thereby preventing the neck and moil portion (68) of the parison tube (58b) from being pinched between the mold halves (24 and 26) in the area of the neck and moil cavity (38).
    Type: Grant
