ABSTRACT:
This relates to a heating system and process for reheating preforms prior to delivering the preforms to a blow molder. The heating system utilizes different types of heating units, one of which will heat the preform wall more highly at the interior surface and the other of which will heat the preform wall at the exterior surface. By effectively controlling the heat input to a preform from each heating unit and by controlling the outputs of the different heating units in combination, the desired temperature profile through the preform wall may be obtained substantially without any time in the oven being provided for heat equilibration and at the same time a maximum heating effort may be effected to produce the necessary heating of a preform within a minimal time and more uniformly than heretofore possible.
