Abstract

L'invention concerne un procédé et un dispositif de flexion pour la flexion progressive de ruban métallique dans la zone d'admission d'un système d'enroulage (3) sans mandrin. Pour éviter le glissement entre le ruban métallique (5) et les cylindres de flexion en mouvement (11, 12, 13), et les dommages résultants sur la surface du ruban métallique, la vitesse périphérique de tous les cylindres de flexion (11, 12, 13) en mouvement est adaptée à la vitesse superficielle (V11, V12, V13) du ruban métallique (5) au niveau de leur ligne de contact (BL11, BL12, BL13) respective avec la surface du ruban métallique.
