  • Publication number: 20140033883
    Abstract: A separator conveying device (300) includes: columnar rotors (310, 320) which hold a separator material (S), which is continuously supplied thereto, on outer circumferential surfaces (311) thereof; and cutting units (350) which cut the separator material in a state where the separator material is held on the outer circumferential surfaces of the columnar rotors, and cut out separators (40) with a predetermined shape. Then, the separators cut out by the cutting units are conveyed by rotating the columnar rotors while maintaining a state where the separators are held on the outer circumferential surfaces. In accordance with the separator conveying device of the present invention, the separators are cut out on the outer circumferential surfaces of the columnar rotors, and accordingly, tension acting on the separators at a time when the separators are cut becomes uniform, and a shape of the separators after the separators are cut becomes stable.
