ABSTRACT:
A system for forming coreless paper rolls having a center aperture of a predetermined cross-sectional configuration. The coreless paper roll is initially formed by winding a web about a first mandrel element having a first cross-sectional configuration and a distal end differing from the predetermined cross-sectional configuration. After the roll is formed it is slid over a second mandrel element having an outer surface with a second cross-sectional configuration to change the shape of the coreless paper roll center aperture from the first cross-sectional configuration to the predetermined cross-sectional configuration.
