Abstract
A method is described for obtaining a coreless roll of web material with a first portion of web material forming an inner nucleus of the roll and a second portion of web material wound around the outside of the inner nucleus. The two portions can be separated from one another and, for that purpose, an interface or discontinuity is created in at least one turn of the web material forming the roll between the inner nucleus and the second portion of web material. This facilitates the extraction of the inner nucleus from the outer portion of the roll.
