In order to enable easily inserting of a tampon by means of enhanced sliding ability of its outer surface area and without hindering other properties of such tampon, which is generally equipped with ribs (11", 12", 13", 14", 15", 16", 17", 18") and grooves (11, 12, 13, 14, 15, 16, 17, 18) on its outer surface, the step of smoothing is proposed in accordance with the present invention, where said tampon is equipped with a covering layer (2) containing thermoplastic fibers, and is then heated exclusively in the area of convex outer surfaces (110", 120", 130", 140", 150", 160", 170", 180") of said ribs (11", 12", 13", 14", 15", 16", 17", 18") such that said fibers become plasticized, upon which the tampon is smoothed by means of exposing it to slight and uniform compression, which is acting radially inwards with respect to the tampon.Afin de permettre linsertion aisée dun tampon au moyen dune capacité de coulissement augmentée de sa surface externe et sans altérer dautres propriétés dun tel tampon, qui est généralement équipé de nervures (11", 12", 13", 14", 15", 16", 17", 18") et de rainures (11, 12, 13, 14, 15, 16, 17, 18) sur sa surface extérieure, létape de lissage est proposée selon la présente invention, où ledit tampon est équipé dune couche de couverture (2) contenant des fibres thermoplastiques, et est ensuite chauffé exclusivement dans la région de surfaces externes convexes (110", 120", 130", 140", 150", 160", 170", 180") desdites nervures (11", 12", 13", 14", 15", 16", 17", 18") de sorte que lesdites fibres deviennent plastifiées, après quoi le tampon est lissé au moyen de lexposition de celui-ci à une compression légère et uniforme, qui agit radialement vers lintérieur par rapport au tampon.
