Abstract

L'invention concerne un procédé de bobinage d'une bande de matériau (4) en circulation, en particulier une bande de matière fibreuse, dans lequel la bande de matériau (4) est bobinée successivement sur plusieurs noyaux de bobine (10, 11) pour donner des rouleaux de bobinage (6), la bande de matériau (4) étant amenée par l'intermédiaire d'un tambour porteur (2), le rouleau de bobinage (6) à former étant détaché du tambour porteur (2) avant le début du transfert de la bande de matériau (4) dans le cas de la formation d'une tension libre, et un nouveau noyau de bobinage (11) étant apporté au niveau du tambour porteur (2), de sorte qu'il est entouré par la bande de matériau (4) au moins dans un secteur périphérique (13). Le procédé selon la présente invention est caractérisé en ce que la bande de matériau (4) dans le secteur périphérique (13), entouré par la bande de matériau (4), du nouveau noyau de bobinage (11) est séparée par un dispositif de séparation (14) produisant deux lignes de séparation (16.1, 16.2), les deux lignes de séparation (16.1, 16.2) se coupant dans le secteur de la bande de matériau (4) et formant ainsi une nouvelle origine (18) de la bande de matériau (4) et un agent adhésif (25) est mis en place entre la bande de matériau (4) et les nouveaux noyaux de bobinage (11) au moins dans le secteur de la nouvelle origine (18) à former.
