ABSTRACT:
A continuous motion pre-form reheat oven for use with a continuous motion stretch blow molding apparatus. The pre-form reheat oven receives pre-forms, reheats the pre-forms, and then discharges the pre-forms onto a moving stretch pin means operatively mounted on a continuous motion stretch blow molding apparatus, as a rotary type stretch blow molding machine. The oven has a pre-form heating zone and a pre-form conditioning zone, and it is adapted to be mounted adjacent a continuous motion stretch blow molding apparatus. The oven includes a plurality of longitudinal tunnels with heater means along each side of each of the tunnels in the pre-form heating zone. The heater means each includes a plurality of heater rods which are separated by heat reflectors and which are each individually temperature controlled. The oven pre-form conditioning zone includes cooling means for cooling the bodies of pre-forms, and heating means for controlling the heat in the neck areas of the pre-forms. Hoist means is provided for raising the oven to an inoperative position. A continuous linear and rotational motion pre-form conveying means is provided for conveying pre-forms from a loading station and through the oven and to a discharge station for discharging the pre-forms onto the stretch pin means.
