This bulk recovery device for nonwoven fabric is provided with a hot air supply source, and with a case unit which includes a base member, a first member which is opposite to a first surface of the base member and partitions a first conveyance space of the nonwoven fabric, and a second member which is opposite to a second surface of the base member on the side opposite of the first surface and partitions a second conveyance space of the nonwoven fabric. This bulk recovery device is arranged such that: the conveyance direction of the nonwoven fabric is different in the first conveyance space and the second conveyance space; the hot air flowing along the conveyance direction from one side to the other side in the conveyance direction is jetted into the first conveyance space from a first jet opening formed in the first surface, and the hot air flowing along the conveyance direction from other side to the one side in the conveyance direction is jetted into the second conveyance space from a second jet opening formed in the second surface; a first hot air chamber, which communicates with the first jet opening through which hot air is supplied, and a second hot air chamber, which communicates with the second jet opening through which hot air is supplied, are formed on the inside of the base member; and the first hot air chamber and the second hot air chamber overlap at least partially in the direction perpendicular to the first surface. |
