Then thesmall hooks on each side of the gripper pass under thepile, over the grasped signature, and lift the signaturesin the box to lessen the friction on the one the gripper draws the signatures out and dropsthem in the conveyor upon the preceding one, the chainmoves those in the conveyor under the next gripper, andthe above action is repeated until the first sheet passesunder each pile and completes a book. The detecting device is operated by the thickness ofthe sheets in the signature or by the signature , if there is one or more sheets missing, or one ormore sheets too many in the signatures, the small hookshown on each gripper arm will catch either on the upperedge or the lower of the notched plate as the signature isthicker or thinner than it should be, and by so catchingwill cause the machine to stop.
