Abstract
An apparatus for recovering bulkiness of a nonwoven fabric by blowing hot air and heating the nonwoven fabric transferred in a transfer direction, includes a case member that has both end portions in the transfer direction opened; an entrance and an exit provided to openings on opposite end sides, in the transfer direction, of the case member to transfer the nonwoven fabric; a wall surface along the transfer direction and located between the entrance and the exit; a blast opening in the wall surface for blasting hot air inside the case member in a blasting direction being the transfer direction or opposite to the transfer direction; and a discharge opening provided to the case member and downstream in the blasting direction. Hot air flows from the blast opening toward the discharge opening while coming into contact with one of two faces of the nonwoven fabric inside the case member.
