Abstract

L'invention concerne un procédé et un enrouleur (1) pour enrouler une bande métallique. La bande est enroulée dans un support d'enrouleur (5) sur un mandrin d'enrouleur (7) pour former une bobine (3) pourvue d'un œil de bobine (49) à travers lequel s'étend le mandrin d'enrouleur (7) et est pressée pendant l'enroulement sur le mandrin d'enrouleur (7) par au moins un élément presseur (9). Le mandrin d'enrouleur (7) est au moins partiellement retiré de l'œil de bobine (49) de la bobine (3) après avoir été enroulé le long d'un axe longitudinal (15) du mandrin d'enrouleur (7). La bobine (3) est maintenue en position par l'au moins un élément presseur (9) et est empêchée de se dérouler. La bobine (3) est fixée après le retrait du mandrin d'enrouleur (7) de l'œil de bobine (49) par un dispositif de protection (11) empêchant le déroulement, et la bobine (3) empêchée de se dérouler par le dispositif de protection (11) est libérée de l'au moins un élément presseur (9) et éloigné du support d'enrouleur (5).
