description The invention relates to a method and device for cleaning extrusion heads (10) in the extrusion of thermoplastics, which are ejected or extruded from an extrusion nozzle (14) as a tubular preform (12). According to the invention, in order to remove interfering deposits and baked-on residues (20) on the outlet nozzle (14), the tubular preform (12) is briefly turned around and upset, wherein the deposits (20) adhering in the vicinity of the outlet nozzle (14) are wiped off and transported away by the tubular preform (12). In an advantageous way, the tubular preform (12) itself is used as a cleaning element while the tubular preform is being turned around, while the cleaning automatically occurs during the ongoing operation of the continuous extrusion without interruption of the production process. La présente invention porte sur un procédé et un dispositif pour le nettoyage de têtes d'extrusion (10) lors de l'extrusion de matières synthétiques thermoplastiques qui sont expulsées ou extrudées, sous forme d'ébauche tubulaire (12), hors d'une filière d'extrusion (14). Selon la présente invention, pour enlever les incrustations et dépôts gênants (20) se trouvant au niveau de la filière de sortie (14), l'ébauche tubulaire (12) est brièvement coudée et refoulée, les dépôts (20) qui adhèrent dans la région proche de la filière de sortie (14) étant alors enlevés et évacués par l'ébauche tubulaire (12). Dans ce processus, l'ébauche tubulaire (12) est avantageusement utilisée elle-même comme élément de nettoyage pendant son changement de direction, le nettoyage s'effectuant automatiquement pendant la marche ininterrompue de l'extrusion continue, sans interruption du processus de fabrication.
