L'ensemble d'entraînement comprend un premier moteur et un second moteur disposés de manière coaxiale. Le premier moteur est disposé en amont du second moteur, et présente une puissance nominale supérieure au second moteur. Le dispositif comprend en outre un dispositif de commande accouplé à l'ensemble d'entraînement, et le dispositif de commande est conçu pour déterminer, sur la base d'une tension cible à appliquer à la bande, une distribution de puissance de sortie respective du premier moteur et du second moteur. Le premier moteur et le second moteur sont tous deux conçus pour fournir une force d'entraînement à l'actionneur en fonction de la distribution de puissance de sortie de façon à appliquer une tension cible à la bande sur l'actionneur. De cette manière, une commutation ininterrompue des modes de fonctionnement de l'ensemble d'entraînement pendant le fonctionnement de l'ensemble d'entraînement est obtenue sur la base de la tension cible sur la bande, ce qui permet d'obtenir une commande précise de la tension sur des bandes ayant des épaisseurs et des spécifications différentes.
