An automotive body framing system includes a setter supported by parallel spaced tracks for movement from a work position to a standby position and to a gate change position and driven by corresponding racks and synchronized pinion drive units. Opposing gate storage belt shuttles are located at the gate change position for receiving the setter therebetween, and a gate staging cart is supported in back of the setter by parallel tracks and is also moved between opposing gate storage belt shuttles by synchronized rack and pinion drive units. Power operated registration units are positioned on the setter to register each gate received at precise horizontal and vertical positions, and the setter, staging cart and gate storage belt shuttles each have a series of resilient guide and support rollers to provide for quiet operation during rapid transfer of the gates on the setter, staging cart and belt shuttles. |
