<p>A sheet inverter system comprising a dual inverter system operatively connecting with a sheet path along which closely sequentially spaced apart printed sheets are fed in use, said dual inverter system comprising two independent but cooperative alternate sheet inverters (12A,12B) and a sheet gating control system (14A,14B). The sheet gating control system (14A,14B) is programmable and operable to alternately direct alternate said closely sequentially spaced apart printed sheets in said sheet path into said alternate independent sheet inverters. <IMAGE></p> |
