Abstract

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.

First claim

What is claimed is:

1. A method of dispensing cushioning wrap material from an unpowered apparatus, the method comprising the steps of:
providing the unpowered apparatus, the unpowered apparatus including a stand with a base member having first and second upwardly-opening slots laterally-spaced apart, each of the first and second upwardly-opening slots including a transversely-extending surface on at least a downstream side of each of the first and second upwardly-opening slots;
inserting a replaceable cartridge into the stand, the replaceable cartridge including a roll of expandable sheet material in an unexpanded form and first and second support panels in abutment with respective axial ends of the roll of expandable sheet material, the first and second support panels being received in the first and second upwardly-opening slots of the stand, wherein the transversely-extending surface of each of the first and second upwardly-opening slots retains the first and second support panels of the replaceable cartridge, respectively, and maintains a rotational resistance of the roll of expandable sheet material as expandable sheet material is pulled from the roll of expandable sheet material;
mounting a roll of interleaf material rotatably secured to the stand; and
concurrently manually pulling interleaf material from the roll of interleaf material and the expandable sheet material from the roll of expandable sheet material while maintaining the rotational resistance of the roll of expandable sheet material such that the expandable sheet material expands to a first expanded form in thickness and in length, and such that the interleaf material and the expandable sheet material in expanded form are in abutting face-to-face contact.

2. A method as set forth in claim 1 , where the manually pulling step is a first manual pulling step, and further comprising the steps of adjusting the rotational resistance of the roll of expandable sheet material after the first manual pulling step, and a second manual pulling step that includes manually pulling the interleaf material from the roll of interleaf material and the expandable sheet material from the roll of expandable sheet material in the unexpanded form such that the expandable sheet material expands to a second expanded form in thickness and in length that is different from the first expanded form provided by the first manual pulling step.

3. A method as set forth in claim 2 , where the adjusting step includes adjusting the length of a connector that extends between the first and second support panels of the replaceable cartridge to adjust the rotational resistance of the roll of expandable sheet material relative to the first and second support panels.

4. A method as set forth in claim 3 , where the connector includes a flexible cord and the adjusting step includes twisting the flexible cord that extends between the first and second support panels to adjust the length of the flexible cord.

5. A method as set forth in claim 3 , comprising the step of removing the replaceable cartridge when the roll of expandable sheet material is depleted and providing a new replaceable cartridge having a new roll of expandable sheet material.

6. A method as set forth in claim 1 , comprising the step of mounting the stand to a support surface.
