ABSTRACT:
Coreless paper roll products are formed by slitting a paper web to form web segments having side edges. The web segments are then wound about an elongated winder shaft. During winding of the paper web, liquid is applied to the web segments only at the side edges thereof while maintaining the web segments free of liquid between the side edges. When the rolls are formed and stripped from the winder shaft, the openings located at the ends of the roll at the roll central aperture will be well defined and allow ready insertion of a dispenser spindle. All the material of the roll can then be dispensed.
