Oval or "racetrack" conveyors are not widely used outside of pad printing. TOSH oval conveyors are motor driven with shot pin alignment mechanisms on the critical print stations. The fixtures move clock wise in an oval. Parts are loaded by the operator on one of the fixtures closest to them and are conveyed under the print head. Conceptually they bridge the gap between a rotary table and a linear indexer.

The main benefit of an oval conveyor is that they present the parts in a straight line to the print head. Linear alignment of the plates may be faster than on a rotary table because multi-color printing on a rotary table requires that the artwork be positioned so as to correct for the angle of the fixture in relation to the print head. Drawbacks of oval conveyors typically include speed, tooling costs and difficulty integrating with systems such as parts feeders.
