An unpowered, manually operable apparatus for dispensing cushioning wrap material drawn concurrently from a roll of separator material and a self-contained cartridge that includes a roll of expandable sheet material. The rolls are supported on a stand for rotation about respective parallel, spaced-apart axes. In addition to the roll, the cartridge includes a tensioning assembly and support panels that abut respective ends of the roll. The tensioning assembly and the support panels cooperate with the stand to control rotational resistance of the roll. The rotational resistance causes the expandable sheet material to expand in length and thickness as it is manually pulled from the stand with the separator material, and support surfaces on the stand hold the cartridge and the separator roll in position. When the cartridge containing the expandable sheet material is depleted, the cartridge is readily removed and replaced.
1-11. (canceled)
A method of dispensing cushioning wrap material from an unpowered apparatus, the method comprising the step of concurrently manually pulling interleaf material from a first roll rotatably secured to a frame and expandable sheet material in an unexpanded form from a replaceable cartridge secured to the frame while maintaining rotational resistance of the second roll such that the expandable sheet material expands to a proper expanded form in thickness and in length, and such that the interleaf material and expandable sheet material in expanded form are in abutting face-to-face contact.
