A folding device (1) for a disposable hygiene article (S) comprises: a first conveying portion (2A) for conveying the disposable hygiene article (S) along a first path (R1)； a second conveying portion (2B) for conveying the disposable hygiene article (S) along a second path (R2) extending in a direction intersecting with the first path (R1)； a folding mechanism (3) used to fold the disposable hygiene article (S) between the first conveying portion (2A) and the second conveying portion (2B), and having a folding component (18)； a driving mechanism (30) connected to the folding component (18), and used to drive the folding component (18) by performing reciprocating linear motion along the second path (R2) between a folding position and a retracted position； and a guiding mechanism (4) for guiding, in an extension direction of the first path (R1) or by using an extension line (R11) of the first path (R1) as a reference, a front end portion of the disposable hygiene article (S) to a side opposite the second conveying portion (2B). The driving mechanism (30) is a structure in which at least one belt wheel (13, 14) is directly connected to a servo motor (12), and a synchronous belt (15) is attached around the belt wheels (13, 14) in a looping path. The folding device (1) performs high speed folding while preventing the disposable hygiene article (S) from wrinkling.La présente invention concerne un dispositif de pliage (1) pour un article d'hygiène jetable (S) comprenant : une première partie de transport (2A) pour transporter l'article d'hygiène jetable (S) le long d'un premier trajet (R1) ； une seconde partie de transport (2B) pour transporter l'article d'hygiène jetable (S) le long d'un second trajet (R2) s'étendant dans une direction croisant le premier trajet (R1) ； un mécanisme de pliage (3) utilisé pour plier l'article d'hygiène jetable (S) entre la première partie de transport (2A) et la seconde partie de transport (2B), et ayant un composant de pliage (18) ； un mé
