ABSTRACT:
A duplex slitter scorer mounted on a single pivoted sub-carrier is provided with a single power adjusting apparatus disposed entirely below the paper feed path. The adjusting apparatus includes a single rotatable lead screw to position a common carrier mounting first and second relatively movable adjusting arms that are selectively engageable in sequence with the slitting and creasing heads. The lead screw axis is fixed transversely and both adjusting arms are retractable to permit indexing of the pivoted sub-carrier. To compensate for paper weave, the sub-frame is moved along its pivot axis. The lead screw is fixed against longitudinal movement but is partially controlled by a signal indicative of sub-carrier position along its pivot axis so that the instantaneous position of the adjusting apparatus common carrier is related to the instantaneous position of the sub-frame along its pivot axis.
