Abstract

Ronces artificielles, bifilaires, constituées d'un fil en acier dur et d'un fil en acier doux caractérisées par le fait que le fil en acier dur 3 est préondulé avant que les deux fils soient torsadés l'un sur l'autre au moyen d'un cadre de torsadage tournant 17. Le cadre 17, tournant autour d'un axe XX à une vitesse constante et à une fréquence égale à la fréquence des ondulations du fil 3 permet, grâce au tambour rotatif 20, de réaliser la ronde par torsadage en disposant le fil rectiligne 2 dans les ondulations dont est déjà doté le fil 3. On facilite et améliore ainsi le torsadage des deux fils l'un sur l'autre. Une telle ronce a un allongement accru grâce à la préondulation du fil en acier dur 3.
