Abstract
A paper inverter system includes a clutch driven inverter nip for maintaining a positive bi-directional contact with the sheet. The apparatus includes a pair of opposing rollers defining a nip therebetween and a shaft connected to at least one of the pair of opposing rollers. A spring is held stationary on a first end and is connected to the shaft on the other end for resisting the rotation of the shaft with a spring force. The clutch responsive to a control signal, selectively couples the shaft to a drive system against the spring force in a first rotational direction and decouples the shaft from the drive system for rotation in a second and opposite direction with the spring force. In another embodiment a clutch operates a planetary gear system to be bi-directionally control the nip.
