Described is a method for making pads (13) of absorbent products, comprising the steps of making a plurality of filaments (4) starting from an extruded polymeric material, with these filaments (4) at a temperature close to the melting temperature of the polymer, depositing these filaments (4) on the outer surface (7a) of a first rotary cylinder (7) shaped to form on it a main layer (6) of non-woven fabric, rolling the surface (7a) of the first cylinder (7) with the outer surface (8a) of a second cylinder (8) rotating with the main layer (6) of non-woven fabric interposed between the surfaces (7a, 8a), crystallising the filaments (4) of polymeric material. L'invention concerne un procédé de fabrication de tampons (13) de produits absorbants, comprenant les étapes consistant à fabriquer une pluralité de filaments (4) en partant d'un matériau polymère extrudé, avec ces filaments (4) à une température proche de la température de fusion du polymère, déposer ces filaments (4) sur la surface externe (7a) d'un premier cylindre rotatif (7) profilé pour former sur celui-ci une couche principale (6) de textile non tissé, faire rouler la surface (7a) du premier cylindre (7) avec la surface externe (8a) d'un second cylindre (8) tournant avec la couche principale (6) de textile non tissé interposée entre les surfaces (7a, 8a) et cristalliser les filaments (4) de matériau polymère.
