BULKINESS RECOVERY APPARATUS FOR NONWOVEN FABRIC AND BULKINESS RECOVERY METHOD

摘要

PROBLEM TO BE SOLVED: To suppress variation in size in a width direction of a nonwoven fabric which may occur in a bulkiness recovery apparatus.SOLUTION: There is provided an apparatus for recovering bulkiness of a nonwoven fabric by blowing hot air to the nonwoven fabric to heat. The apparatus includes: a conveyance unit for conveying the nonwoven fabric that is continuous in a conveyance direction along the conveyance direction; a heating unit for heating the nonwoven fabric by blowing the hot air to the nonwoven fabric during conveyance; a width sensor for outputting information relating to a size in a width direction by measuring the size in the width direction of the nonwoven fabric in a position on a downstream side in the conveyance direction of the heating unit; and a controller for controlling at least one of the heating unit and the conveyance unit based on the information output from the width sensor.
