Abstract
In high speed reproduction apparatus in which closely spaced printed sheets are sequentially fed downstream in a sheet path at a process velocity, a dual inverter system of two independent but cooperative sheet inverters is sheet control gated to receive alternate sheets from the sheet path for inversion in the alternate independent sheet inverters. These dual alternate sheet inverters may advantageously operate at substantially the same sheet velocity as the connecting sheet path, instead of the much higher speed and acceleration/deceleration typical of conventional single inverter systems. This enables less critical higher speed cut sheet handling and thus more reliable faster printing. Yet collated sequential sheet order is maintained. This dual inverter system may be an integral part of a duplex path to provide inversion of sheets for duplex printing of their other sides.
