METHOD AND APPARATUS FOR CONDITIONING PREFORMS IN AN INJECTION STRETCH BLOW MOLD MACHINE

摘要

The conditioning station of an injection stretch blow mold machine is provided with a heater ring for each hot, soft preform presented to the station. The heater ring emits infrared light waves that are confined to the transition region of the preform between the neck and main body portions to pin-point the addition of heat to the transition region.
