Abstract (en)
A method of forming coreless paper rolls from an elongated, coreless paper log includes applying moisture (30) to the log as it is wound to form discrete bands of moistened paper separated by unmoistened log portions. After the log has been wound and the spaced bands of moisture formed on the log, the log is slid axially from a winder shaft (16) and cut into individual coreless paper rolls. The cuts are made between the edges of the bands of moisture and the log is sawn while one band edge is located on the winder shaft.
