Abstract

La présente invention concerne un dispositif d'enroulement (1) équipé d'un mécanisme d'entraînement (30) destiné à un noyau d'enroulement (2) et d'une unité de commande (60). Selon l'invention, l'unité de commande (60) comporte un moyen de stockage (61) et un moyen de réglage de quantité de rotation (63). Le moyen de stockage (61) stocke des données mesurées révélant une série temporelle de la quantité enroulée cumulée d'une feuille d'électrode (3) enroulée sur le noyau d'enroulement (2) et des données cibles révélant une série temporelle de la quantité enroulée cumulée de la feuille d'électrode (3) lorsque celle-ci est enroulée à une vitesse d'enroulement constante. Le moyen de réglage de quantité de rotation (63) règle la quantité de rotation d'un arbre de sortie (11a) de façon à réduire la différence entre les données mesurées et les données cibles. À l'aide de cette configuration, la vitesse d'enroulement de la feuille d'électrode (3) peut être maintenue constante.
