The invention relates to a centre-feed, core-free roll (10', 20, 30) comprising a sheet (10) of flexible dry material, such as a fibrous absorbent material, which is formed by winding said sheet around a winding axis. The invention is characterised in that the roll comprises a central initial unwinding section (10B, 21, 31) which forms a protrusion along the length of the aforementioned axis in relation to at least one part of the plane of one of the sides of the roll. Moreover, the initial unwinding section comprises a portion belonging to the inner end of the roll-forming sheet. In this way, the first inner coil can be unwound even when the central hole is reduced.
L'invention porte sur un rouleau sans mandrin (10', 20, 30) composé d'une feuille (10) de matériau souple non humide tel qu'un matériau fibreux absorbant, formé par enroulement de la feuille autour d'un axe de bobinage, caractérisé par le fait qu'il comprend une amorce (10B, 21, 31) de dévidage central formant une saillie le long dudit axe, par rapport à au moins une partie du plan de l'un des flancs du rouleau. En particulier, cette amorce est constituée par une portion de l'extrémité interne de la feuille constituant le rouleau. On permet ainsi de dévider la première spire interne, même lorsque le trou central est réduit.
