ABSTRACT:
A gateless rocker inverter for reversing the lead and trail edges of a sheet includes two idler roll and drive roll nip pairs with the drive rolls continuously rotating in opposite directions. The idler rolls are attached to two ends of a coupler of a four-bar linkage which opens and closes the nips in sequence, first to drive the sheet forward and subsequently to drive the sheet in a reverse direction out of the inverter for duplexing purposes.
