A system for transporting a separator by using an air guide roller includes an air guide roller controller and an air guide roller configured to receive a control command from the air guide roller controller and to spray the air onto one surface of a separator when the separator travels.

A manufacturing method for a glass film includes at least a cutting step of cutting a strip-shaped glass film while conveying the glass film in a predetermined direction by a conveying device. In the cutting step, the glass film is cut in predetermined cutting zones by irradiating the glass film with laser beams. A support conveyance surface of the conveying device for the glass film is separated at the cutting zones for the glass film. Further, a first surface plate capable of supporting the glass film in a contact manner is disposed at a position that is located in a width direction of the glass film with respect to the cutting zones and corresponds to a center of a glass film obtained by the cutting in the width direction.

A web conveying device includes a roller portion, a first air passage, a second air passage, and an air current generation portion. The roller portion rotates in contact with a web. The first air passage extends in an axial direction of a rotation shaft of the roller portion inside an outer peripheral portion of the roller portion and communicates with an outside at an end on a side of a first direction parallel to the axial direction. The second air passage extends from the first air passage in a direction that forms an obtuse angle with respect to the first direction and communicates with the outside of the outer peripheral portion. The air current generation portion generates an air current that flows in the first air passage in the first direction.
