Abstract

According to some embodiments, methods of adjusting frictional resistance of an expandable slit sheet paper dispensed from a manual dispenser include, e.g.: supporting a roll of expandable slit sheet paper on a frame of the dispenser, said roll of expandable slit sheet paper having an initial diameter; manually pulling a distal end of the roll of expandable slit sheet paper from a perimeter of said roll such that the expandable slit sheet paper extends along an arc around a portion of a periphery of at least one bar that extends across a width of said expandable slit sheet paper, whereby applying a frictional resistance to the expandable slit sheet paper that causes said expandable slit sheet paper to expand and form open cells; and after dispensing expandable slit sheet paper from said roll such that a diameter of said roll is reduced from said initial roll diameter, adjusting said frictional resistance to the expandable slit sheet paper that causes said expandable slit sheet paper to expand and form open cells by altering a path of the expandable slit sheet paper around said at least one bar such as to increase the frictional resistance applied to the expandable slit sheet paper.
