The present invention relates to a system for thermally profiling preforms prior to blow molding. The system includes a pallet for holding a plurality of preforms and a station, such as a heating oven, for thermally conditioning the preforms. In a first embodiment, the pallet comprises a self aligning pallet which is movable towards and away from the heating oven. In a second embodiment, the pallet holding the preforms is fixed in position and the heating oven is movable towards and away from the preforms. The pallet further includes rotatable mandrels for supporting the preforms and a programmable motor for rotating the preforms a desired amount and at a desired speed.

Oven-pallet alignment and profiled heating of preforms

An inventive orientation apparatus is provided in the present invention preferably for use with blow molding operations. The apparatus includes an object having a body portion and a neck portion. The neck portion has an outer peripheral surface and an alignment lug which extends outwardly from the peripheral surface and past the same. Additionally, a rotating support is included for supporting the object and causing the same to rotate, wherein the rotating support is movable with a moving carrier pallet. The apparatus also includes an orientating element located adjacent the carrier which engages the alignment lug on the object and stops the rotation of the object at a desired orientation. The invention may also include an orientation check device which is positioned upstream from the orientation element, adjacent the carrier, which is used for checking the orientation of the alignment lug for preventing a system jam.
