ABSTRACT:
A reheating and blow molding system utilizing an indexing plate having pairs of core pins mounted on the periphery. Radiant heaters heat parisons mounted on the core pin to a temperature suitable for blow molding while the parisons are rotated in response to movement of a spin belt. Rotation of the parisons during heating provides greater uniformity of heating. Tapered shanks remove the core pins from core pin holders and dispose the parisons in a mold for blow molding. The core pins are then disposed in the core pin holders and indexed to a subsequent indexing location where the finished article is removed.
