Abstract

L'invention concerne un procédé et un dispositif auxiliaires (1) pour ouvrir des bottes de fibres (2) comprimées qui sont pourvues d'au moins un cerclage (3) et, éventuellement, d'un emballage. La botte de fibres (2) est, à l'aide d'une presse (4), soumise à une pression au niveau d'au moins deux côtés de botte (16) opposés et recouverts des cerclages (3), et ainsi comprimée. Cette réduction de la botte soulage les cerclages (3) qui dépassent ainsi, de façon lâche, sur au moins un autre côté de botte (17) libre. Dans cette zone lâche (12), les cerclages (3) sont ensuite coupés et retirés de la botte de fibres (2) manuellement ou mécaniquement.
