ABSTRACT:
A paper cutting device for cutting sheet material from the lengthwise edges of the material toward the middle comprising a stationary blade and first and second movable blades with the sheet material placed between the stationary blade and the first and second movable blades. The paper cutting device enables the spacing between the stationary blade and the first and second movable blades to be opened by moving the stationary blade frame and the movable blade frame relative to each other. The first movable blade and second movable blade are supported on a first stud and second stud, respectively, near the distal ends of the edge of the blade part of the stationary blade so that the paths of the blade tips overlap when cutting the sheet material. The movable blade drive mechanism drives the first movable blade and second movable blade with the first movable blade leading and the second movable blade following.
