A method for conveying a strip plastic film that can appropriately change the conveyance path for a strip plastic film continuously conveyed from an upstream side such as a raw film to a downstream side includes, when the strip plastic film conveyed from the upstream side is conveyed to the downstream side while being wound on the outer surface of a guide member in at least the central region in the width direction of the film, moving, rotating, or tilting the guide member that has the strip plastic film wound thereon via a base connected to the guide member to change the frictional resistance of the strip plastic film with respect to the guide member and the tension of the strip plastic film, thereby allowing the strip plastic film to slide along the outer surface of the guide member, and thus changing the conveyance path for the strip plastic film.
A method for conveying a strip plastic film, comprising, when a strip plastic film conveyed from an upstream side is stretched on an outer surface of a guide member in at least a central region in a width direction of the film, and the strip plastic film is conveyed to a downstream side with the stretched state maintained, and is also folded in the width direction:
A conveyance guide for a strip plastic film, the conveyance guide being adapted to allow a strip plastic film conveyed from an upstream side to be folded at a desired position in a width direction of the film while allowing the strip plastic film to be stretched on an outer surface of the conveyance guide and thus guiding the strip plastic film to a downstream side, the conveyance guide comprising:
