Abstract:
In a high speed reproduction apparatus with a sheet path in which closely sequentially spaced apart printed sheets are fed downstream in said sheet path in an original sheet sequence, said sheet path having an operative connection to a sheet inverter system into which said closely sequentially spaced apart printed sheets in said sheet path are fed to be inverted, the improvement wherein:said sheet inverter system comprises dual inverter system operatively connecting with said sheet path, said dual inverter system comprising two independent but cooperative alternate sheet inverters and a sheet gating control system, said sheet gating control system being programmable and operable to alternately direct alternate said closely sequentially spaced apart printed sheets in said sheet path into said alternate independent sheet inverters, and wherein said two independent but cooperative alternate sheet inverters are operatively connected to said sheet path to be alternatingly fed alternate sheets from said sheet path and to return sheets to said sheet path in said original sheet sequence; and wherein said two independent but cooperative alternate sheet inverters are spaced on opposite sides of said sheet path, wherein said two independent but cooperative alternate sheet inverters on opposite sides of said sheet path are connected in parallel with said sheet path to alternately receive said closely sequentially spaced apart printed sheets from said sheet path and to return said closely sequentially spaced apart printed sheets to said sheet path.
