US Patent 7568684 Signature transport device with inhibit feature

A signature transport device includes a first conveyor moving a first signature and a second signature in a first direction. A signature lifting device removes the first signature from the first conveyor and a gripper removes the first signature from the signature lifting device at a first location. The signature lifting device has an inhibit position where the second signature follows a path, the path bypassing the first location so that the gripper bypasses the second signature. The present invention also provides for a method for transporting signatures.
