ABSTRACT:
A parison stick is used with an injection-blow molding machine for injection-blow molding of a hollow article of plastic material from a parison of this plastic material. The stick has three axially-contiguous portions. The portion (A) connects the parison stick to the injection-blow molding machine. The portion (B) positions the parison stick in the wall of a mold within the machine. The portion (C) terminates in the cavity of the mold and includes distinctly and axially-spaced first and second openings through which gas blows and inflates a parison previously injected around this portion. The openings are connected to a gas-feed chamber via at least one channel. The parison stick further includes at least one obturator connected to an actuator which is controlled by a control member of the machine.
