When a sheet of plastic wrap is wound around noodle strips, a folded portion of the sheet of plastic wrap is held between layers of the noodle strip and is double wound on an outer side of the noodle strip. The sheet of plastic wrap covers an entirety of the wound noodle strip. The sheet of plastic wrap on an outer peripheral side of the folded sheet of plastic wrap extends from and is wound around a next noodle strip. Next, another folded portion of the sheet of plastic wrap is held between layers of the next noodle strip and is double wound on an outer side thereof. The sheet of plastic wrap sequentially covers an entirety of the next noodle strip.
