A roll type inverter system 10 with an independently driven duplex pinch roll device 12 is depicted in the figure. This inverter comprises a reversibly driven inverter roll 14 and an escort belt 16 which forms an endless belt around guide rollers 11, 13, 15, and 17. The escort belt is in driving contact around almost half of the inverter roll to form an elongated nip through which a document 18 may be passed. The duplex roll device comprises a drive roll 19 and pinch roll 21 which rolls do not reverse the direction of rotation during the duplex mode.
