Abstract
A dielectric heating section for a blow molding machine is provided. Within the heating section a plurality of heating stations are defined by electrode pairs. At least one electrode of each pair is made recontourable to achieve the desired temperature profile within the wall section of a thermoplastic preform suspended therebetween. The preforms are rotated while supported within the alternating electric field created between the electrodes when the electrodes are energized by a radio frequency signal generator. The preforms are moved from station-to-station to achieve high rate controlled heating of each preform.
