Abstract
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.
