The present invention is relative to a melt spinning apparatus for melt spinning a biodegradable polymer material. The biodegradable polymer material is melted by a melt mechanism (4) including a screw (16) which is mounted in a vertically mounted cylinder (8) coaxially with the cylinder (8) and which is rotationally driven by a rotational driving mechanism (7). The screw includes at least one turn of a helical groove (17) on its peripheral surface. The biodegradable polymer material being melted in this way is discharged in the vertical direction from a discharge opening of a nozzle (10) mounted coaxially on the cylinder (8).

L'invention concerne un dispositif de fonte et de centrifugation capable de fondre et de centrifuger un matériau polymère biodégradable. Ce dispositif est caractérisé en ce que le matériau polymère biodégradable est fondu au moyen d'un mécanisme de fonte (4) comprenant une vis (16) logée dans un cylindre disposé de manière verticale (8) et étant coaxiale avec celui- ci (8), la vis (16) étant entraînée de manière rotative par un mécanisme d'entraînement rotatif (7), ainsi qu'une rainure hélicoïdale (17) d'au moins une rangée formée au niveau de la surface périphérique de celle-ci, et en ce que le matériau polymère biodégradable fondu est déchargé de manière verticale à partir de l'orifice de sortie d'une buse (10) disposée de manière coaxiale avec le cylindre (8), aux fins de centrifugation.
