1. A folder comprising:
- a first cylinder having at least one first gripper for holding signatures and at least one tucker for tucking the signatures to define a first fold;
a second cylinder having at least one first jaw for holding the signatures at the first fold;
a first motor driving the at least one first gripper; and
a second motor separate from the first motor, the second motor driving the at least one tucker of the first cylinder and the at least one first jaw of the second cylinder.

6. A folder comprising:
-
cutting cylinders for cutting a web of material into signatures, a first cylinder having at least one first gripper for holding the signatures at a lead edge and at least one first tucker for tucking the signatures to define a first fold;
a second cylinder having at least one first jaw for holding the signatures at the first fold and at least one second jaw for holding the signatures at a second fold;
a third cylinder having at least one second gripper for holding the signatures at the first fold and at least one second tucker for forming the second fold;
a first motor driving the cutting cylinders and the at least one first gripper;
a second motor independent from the first motor, the second motor driving the at least one first tucker of the first cylinder, the at least one first jaw of the second cylinder, and the at least one second gripper of the third cylinder; and
a third motor independent from the first and second motors, the third motor driving the at the one second jaw of the second cylinder and the at least one second tucker of the third cylinder. - View Dependent Claims (7, 8, 9)

10. A folder comprising:
-
at least one cutting cylinder pair;
a first cylinder having at least one first gripper for holding signatures and at least one first tucker for tucking the signatures to define a first fold;
a second cylinder having at least one first jaw for holding the signature at the first fold and at least one second jaw for holding the signature at the second fold;
a third cylinder having at least one second gripper for holding signatures and at least one second tucker for tucking the signatures to define a second fold;
