A feed roll (110), a nudger roll (112), and a retard roll (114) are aligned so that their axes of rotation are in the same plane within a frame (102). The frame is inserted into the feed head and pivoted into an active position. Upon insertion into the feed head, the retard roll is captured by a separate retard bracket so that when the feed head is pivoted into the active position the retard roll is withdrawn from the frame and forms a feed nip with the feed roll. A gear train (111,113,115) is provided on both sides of the cartridge to drive the feed roll and the nudger roll. A notch in the frame supports the retard roller so that upon pivoting the frame from one position to another the retard roller is released from the frame. |
