Abstract
There is provided a bulkiness recovery apparatus for nonwoven fabric, the apparatus being for recovering bulkiness of the nonwoven fabric by blowing hot air to heat the nonwoven fabric. The apparatus includes: a conveying section that conveys the nonwoven fabric along a conveying direction, the nonwoven fabric being continuous in the conveying direction; a heating section that heats the nonwoven fabric by blowing the hot air to the nonwoven fabric being conveyed; a width sensor that measures a widthwise dimension of the nonwoven fabric at a position downstream from the heating section in the conveying direction, and that outputs information concerning the widthwise dimension; and a controller that controls at least either one of the heating section and the conveying section based on the information that has been output from the width sensor.
