ABSTRACT:
This relates to a blow molding apparatus wherein plural preforms are directed to plural cavity blow molds by way of a pallet which supports the preforms by neck portions thereof. The pallets are positioned relative to blow molds of a set by way of a track. The track is transversely shiftable to present preforms transversely of the blow mold halves prior to the closing of the blow molds and there is associated with supports for the track wedge members which automatically lower the track relative to the blow molds more closely to position a supporting flange of each preform with respect to the upper surface of the blow molds. The track is finally further moved downwardly to engage the support flanges of the preforms with the top surfaces of the blow molds under controlled pressure conditions by means of fluid cylinders. This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application.
