driving with a third motor a third loop for tucking the signature into a second jaw.
2. The method as recited in claim 1 further including altering a phase between at least the first and second loops, so as to set a lap or perform mode change.
3. The method as recited in claim 1 further including using a phasing center to alter a phase between a tucker in the second loop and the first jaw so as to perform a group jaw adjust.
4. The method as recited in claim 1 further including using a phasing center to alter a phase between a tucker and a second jaw in the third loop so as to perform a group jaw adjust.
