  • Method and apparatus for cross-folding signatures
    Patent number: 5547452
    Abstract: A collecting cylinder and a folding flap cylinder cooperate to form a cross-folding device for signatures in a rotary printing press. The leading edge of each signature is initially retained on the collecting cylinder and is held there after insertion of the cylinder into the folding flap. The trailing edge of the signature is transferred to grippers on the folding flap cylinder at a point where the two cylinders are in contact. Operation of the cross-folding device results in reduced folded product damage.
