PROBLEM TO BE SOLVED: To provide a bulkiness recovery apparatus for a nonwoven fabric which can suppress the reduction of a bulkiness recovery effect by heating of the nonwoven fabric, and which is reduced in size.SOLUTION: A bulkiness recovery apparatus 50 for a nonwoven fabric includes: a case unit including a base member, a member which faces a first surface of the base member and demarcates a first transfer space A1 for a nonwoven fabric 3, and a member which faces a second surface opposite to the first surface and demarcates a second transfer space A2 for the nonwoven fabric; and a hot air supply source 13. The first transfer space and the second transfer space are different from each other in the transfer direction of the nonwoven fabric. Hot air flowing from one side to the other side in the transfer direction is injected from a first injection port formed in the first surface into the first transfer space, and hot air flowing from the other side in the transfer direction is injected from a second injection port formed in the second surface into the second transfer space. A first hot air chamber communicating with the first injection port and a second hot air chamber communicating with the second injection port are formed within the base member. The first and second hot air chambers are arranged so as to at least partly overlap each other in a direction orthogonal to the first surface. |
