ABSTRACT:
Upon leaving the mold, plastic bottle preforms are engaged internally and/or externally by pneumatic suction grips which form an annular chamber (15, 27) through which atmospheric cooling air is circulated. This increases the rate of production of the preforms by cooling them during handling, rather than separately at a discrete cooling station.
