L'aggloméré comporte une région centrale creuse (22, 28). Au moins un dispositif de déroulage (16, 18) est supporté à l'intérieur de la région centrale creuse du ou des agglomérés. Le dispositif de déroulage comporte une tête (50), au moins un tube, une sortie, et un passage (38) à travers celui-ci. Un appareil d'enroulage est positionné en aval du dispositif de déroulage. L'appareil est caractérisé en ce que la tête du dispositif de déroulage a une forme de section transversale en ogive tronquée, et en ce que l'appareil est configuré pour maintenir une tension sur les brins ou sur les extrémités, de façon à réduire ainsi sensiblement une rupture et à réduire ainsi sensiblement la formation de boucles, d'emmêlements ou de nœuds.
