The conveyor system is disclosed as appended to a web-fed printing press, for transporting the completed signatures from a delivery fan to a stacking station. Included is a first conveyor having a pair of endless chains each having a series of first grippers in transverse alignment with their counterparts on the other endless chain. Each transversely aligned pair of first grippers conjointly grips, in a loading position immediately downstream of the delivery fan, a signature at two spaced points on one edge thereof and releases the same in a transfer position intermediate the delivery and stacking station. A second conveyor has but one endless chain with a series of second grippers mounted thereto. Each second gripper grips, in the transfer position, the signature at a point on the edge thereof intermediate the two spaced points where the signature has been gripped by one pair of first grippers on the first conveyor, and releases the signature at the stacking station. The two conveyors are driven independently of each other.
