ABSTRACT:
An open end parison preform is heated to molding temperature preparatory to transfer to a molding station. The thus heated parison is grasped by a pair of opposed picker fingers and transferred into position over a neck forming plug. The relative temperature of the opposed picker fingers is controlled which effects the alignment of the bottom end of the parison over the plug.
