Abstract:
A coreless, collapse-resistant center feed roll comprising cellulosic sheet material wound into a roll along a central axis, the roll having:a circumferential outer surface; anda first end and a second end, each end being composed of edges of the sheet material and defining an opening that extends through the roll along the central axis as a hollow inner core,so the sheet material at the hollow core is adapted to dispense from the roll through one of the openings while the roll remains stationary, wherein the roll includes at least one region where cellulosic sheet material of the roll is stiffened by adding an aqueous liquid to at least one end of the roll away from the hollow inner core and allowing the material to dry to reduce the likelihood that sheet material will collapse into the hollow inner core during dispensing of sheet material through one of the openings.
