Slit sheet tensioning device

In combination:

• A) a device for dispensing expandable slit sheet paper, comprising:
• a rod member adapted to mount an assembly of an interior core member with a roll of expandable slit sheet paper wound on the interior core member,
• said rod member having a first rod member end region,
• a support member,
• said first rod member end region being secured to said support member,
• said rod member having a second rod member end region at an opposite end of said rod member from said first rod member end region,
• said rod member being adapted to receive the assembly of the interior core member with the slit sheet paper wound on the interior core member,
• a pressing member that is movable to apply a frictional resistance to inhibit rotation of the core member, and a spring arranged to apply a spring force against said pressing member,
• further including a manually adjusted member that is arranged to apply a pressure against said spring such as to adjust the spring force applied by the spring against said pressing member;
• and
• B) an assembly of an interior core member with a roll of expandable slit sheet paper wound on the interior core member;
• wherein said interior core member is a hollow cylindrical tube made with paper,
• wherein said rod member extends through an interior of said hollow cylindrical tube, and
• wherein said pressing member is configured to contact a cylindrical surface of said hollow cylindrical tube such as to apply a pressure force against said cylindrical surface of said hollow cylindrical tube to apply said frictional resistance to inhibit rotation of the core member;
• and
• wherein said rod member includes two elongated portions extending parallel to an axis of and entirely through a length of said core member, said two elongated portions being adapted to support the core member at two respective points of contact at opposite sides of said axis of the core member.
