A bulkiness recovery apparatus for nonwoven fabric includes a hot-air source; and a case unit including a base member, and first and second members. The first and second members face opposite first and second surfaces of the base member and partition first and second conveyor spaces. The base member has first and second hot-air chambers. The first and second surfaces have first and second jet inlets. The first and second hot-air chambers at least partly overlap in a direction normal to the first surface. First and second conveying directions of the nonwoven fabric in the first and second conveyor spaces are different. Hot air flows along the first conveying direction and is blasted from the first jet inlet into the first conveyor space. Hot air flows along the second conveying direction and is blasted from the second jet inlet into the second conveyor space.
