There is provided a stripper assembly (212) for use in a mold stack (202) for forming a preform (210) suitable for blow-molding into a final-shaped container. The stripper assembly (212) comprises a stripper plate (214) connectable, in use, to a stripper plate actuator; neck rings (220) configured to cooperate to define a portion a neck region (226) of the preform (210); a stripper ring (230) configured to define at least a portion of a top sealing surface of the neck region (226) of the preform (210); the stripper plate (214) being configured to actuate the neck rings (220) and the stripper ring (230), in unison, along substantially the whole length of a complete ejection path, which is substantially parallel to a longitudinal axis of the mold stack (202); and wherein the neck rings (220) are configured for movement in a direction substantially perpendicular to the longitudinal axis of the mold stack, over at a portion of the complete ejection path, the stripper ring (230) having an air channel (236) configured to directed a flow of fluid towards the preform. |
