Zusammenfassung:	The present invention relates to a method for winding preforms in order to produce tampons. In the method according to the invention, a material band is supplied. Band-like strips are separated from this material band and, by means of at least one drive roller (19), are pushed into a continuously rotating winding drum (16) such that the strip is positioned between a winding fork and a blade in such a way that, when the winding fork moves around the blade, the blade presses a portion of the strip into a fork spacing of the winding fork and thus allows entrainment. The present invention also relates to a corresponding device for carrying out the method according to the invention. La présente invention concerne un procédé d'enroulement de préformes pour la fabrication de tampons. Dans le procédé selon l'invention, une bande de matériau est fournie. Des rubans de type bande sont séparées de cette bande de matériau et, au moyen d'au moins un rouleau d'entraînement (19), sont poussés dans un tambour d'enroulement à rotation continue (16) de telle sorte que le ruban est positionné entre une fourche d'enroulement et une lame de telle sorte que, lorsque la fourche d'enroulement se déplace autour de la lame, la lame presse une partie du ruban dans un espacement de fourche de la fourche d'enroulement et permet ainsi l'entraînement. L'invention concerne également un dispositif pour mettre en uvre le procédé selon la présente invention.
