ABSTRACT:
This relates to a loader for loading preforms into collets of pallets in a blow molding machine wherein a plurality of preforms are simultaneously loaded into the blow molding molds during each operation of the machine. The loader includes a preform supply wherein there is a preform receptacle having a number of preform pockets corresponding to the number of preforms to be loaded in a pallet. A preform carrier is moved between a position underlying the preform receptable for receiving preforms therefrom to a position underlying a pallet presented to the loading station. The preform positioning device then engages the bottoms of preforms and moves the preforms up through the preform carrier into the lower end of the collets of pallets where they are automatically retained in place by spring loaded detents. This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application.
