Abstract
A device and method for excellent recovery of bulk in nonwoven fabric. While nonwoven fabric is transported so as to enter a heating chamber via an entry opening and, after progressing within the heating chamber, exit the heating chamber via an exit opening, heated air is supplied at a speed higher than the transport speed for the unwoven fabric so as to enter the heating chamber via the entry opening and after progressing within the heating chamber while contacting the nonwoven fabric, exit the heating chamber via the exit opening.
