Zusammenfassung:	The invention relates to a process for producing a glass fiber-reinforced thermoplastic polymer composition, comprising the sequential steps of: a) unwinding from a first package of at least one first continuous glass multifilament strand having a first filament thickness t1 and a second package of at least one second continuous glass multifilament strand having a second filament thickness t2 larger than the first filament thickness t1 and b) applying a sheath of a thermoplastic polymer composition around the at least one first continuous glass multifilament strand and the at least one second continuous glass multifilament strand to form a sheathed continuous multifilament strand comprising the at least one first continuous glass multifilament strand and the at least one second continuous glass multifilament strand. L'invention concerne un procédé de fabrication d'une composition polymère thermoplastique renforcée par des fibres de verre, comprenant les étapes séquentielles suivantes : a) le déroulement d'un premier paquet d'au moins un premier brin multifilament de verre continu ayant une première épaisseur de filament t1 et d'un second paquet d'au moins un second brin multifilament de verre continu ayant une seconde épaisseur de filament t2 plus grande que la première épaisseur de filament t1 et b) l'application d'une gaine d'une composition de polymère thermoplastique autour dudit premier brin multifilament de verre continu et dudit second brin multifilament de verre continu pour former un brin multifilament continu gainé comprenant ledit premier brin multifilament de verre continu et ledit second brin multifilament de verre continu.
