A method is described for obtaining a coreless roll (R) of web material with a first portion of web material forming an inner nucleus (R1) of said roll and a second portion of web material (R2) wound around the outside of said nucleus. The two portions (R1 , R2) can be separated from one another and, for said purpose, an interface or discontinuity is created in at least one turn of the web material forming the roll, between said inner nucleus and said second portion of web material, so as to facilitate the extraction of the inner nucleus from the outer portion of the roll.
L'invention concerne un procédé d'obtention d'un rouleau sans noyau ( R ) d'un matériau en bande continue, comprenant une première portion de matériau en bande formant un noyau intérieur (R1) dudit rouleau, et une seconde portion de matériau en bande (R2) enroulée sur le pourtour extérieur dudit noyau. Les deux portions (R1, R2) peuvent être séparées l'une de l'autre et, à cet effet, une interface ou une discontinuité est créée dans au moins un tour du matériau en bande formant le rouleau, entre ledit noyau intérieur et ladite seconde portion de matériau en bande, de manière à faciliter l'extraction du noyau intérieur de la portion extérieure du rouleau.
