La tension d'un corps élastique (30) qui tire dans une section de retenue (10) une pièce de tirage (20) accrochée sur le fil (3Y) dévidé à partir d'une bobine (3) est mesurée par un dispositif de mesure de tension (40). Ensuite, grâce à un dispositif de dérivation (50), utilisant la corrélation prédéterminée entre la tension du corps élastique (30) et la position (une quantité physique pour la régulation de la quantité de fil (3Y) alimentée à partir de la bobine (3)) de la pièce de tirage (20) dans le sens du tirage, ladite position est déterminée à partir de la tension mesurée réelle. En se basant sur la position déterminée, la quantité de fil (3Y) alimentée à partir de la bobine (3) par le dispositif d'alimentation en fil (1) est régulée par un dispositif de régulation (1C).
