ABSTRACT:
A continuously wound strip of toweling, either solid wound or wound about a hollow central core, forms the roll with radial end surfaces. A pair of diametrically aligned, axial pin openings are formed in one of the roll end surfaces equally radially spaced from the central longitudinal axis with radially inner extremities radially outwardly of any roll core. If the roll is solid wound, a central axial opening is formed in the other roll end surface preferably semi-spherical in shape or if the roll is hollow core wound, the core forms the central axial opening at the other roll end surface. In either case, with dispenser pin support and central support at the opposite roll ends, dispensing unwinding of the strip of toweling to the pin hole radially inner extremities releases the roll for endwise pivoting about the other roll end automatically dismounting the same. In addition to the central opening at the other roll end surface, a circumferential groove may be formed therein radially outwardly of the central opening to adapt the roll for versatile use with known dispenser dismounting structures.
