ABSORBENT ARTICLE PRODUCTION DEVICE, AND MODIFICATION METHOD FOR PRODUCTION DEVICE

An absorbent article manufacturing apparatus includes: a first conveying route (R11) that is arranged in a straight line along a first direction in plan view; a plurality of processing devices that process an intermediate product of an absorbent article (1) that is conveyed along the first conveying route (R11) ; and a heating unit (61) that restores bulk of a non-woven fabric (3a) through heating the non-woven fabric (3a) by blowing hot air onto the non-woven fabric (3a) while conveying the non-woven fabric (3a) along a direction in which the non-woven fabric is continuous, the non-woven fabric (3a) being a strip shape and serving as a part of the absorbent article (1). In a case where a direction that intersects the first direction in plan view is set as a second direction, the heating unit (61) is arranged in one of a position that is directly above the first conveying route (R11) and a position that is displaced from the first conveying route (R11) to the second direction.
