Linear folding device and method

摘要

A signature folding device includes a rotating belt and a plurality of blades attached to the belt, each of the plurality of blades contacting one of the signatures over an entire length of the one signature at a same time. Also disclosed is a method for folding a signature comprising transporting the signature on a fold table having a gap, the signature moving in a transport direction and forming a plane. A folding blade having a blade edge is moved in a direction both perpendicular and parallel to the transport direction, the blade edge being parallel to the plane upon contact with the signature, so as to pass through the gap and fold the signature.
