Abstract
A conveyor is provided with a supply roll, a corrective holding part and an additional holding part. The supply roll rotatably supports a belt-shaped cell material for an electrode or a separator. The corrective holding part conveys and holds the cell material fed out from the supply roll while bending a first side surface of the cell material that lies against an outer peripheral side of the supply roll into a concave shape. The additional holding part conveys and holds the cell material while bending a second side surface of the cell material into a concave shape. The holding parts include a curved contact surfaces that contact opposite side surface of the cell material. The curved contact surface of the corrective holding part has a radius of curvature that is less than a radius of curvature of the curved contact surface of the additional holding part.
