Abstract
Stock material units that may be used in a dunnage conversion machine. For example, stock material units include sheet material that may be fed into the dunnage conversion machine and may be converted thereby into dunnage.
Claims20
A method of assembling a stock material unit for a dunnage conversion machine, comprising:
- providing a three-dimensional body of a continuous, fan folded, first sheet of stock material, the fan folded first sheet having a plurality of substantially parallel folds that define opposing sheet sections including, first and second sheet sections, the first sheet section overlaying the second sheet section, the first sheet being adapted to be drawn from the three-dimensional body and convertible into low-density dunnage by a dunnage converter;
- non-removably attaching a first portion of a first adhesive to a surface of the first sheet section;
- and
- removably attaching a second portion of the first adhesive to the second sheet section, thereby removably securing the first sheet section to the second sheet section, such that the first sheet section can be folded away from the second sheet section to expose the second portion of the first adhesive for contacting and splicing to a second sheet of the stock material, wherein the first adhesive is selected to have sufficient adhesive strength after removal of the second portion of the first adhesive from the second sheet section to splice the first sheet to the second sheet of stock material so that the dunnage converter can draw one of the first or second sheets of stock material into the dunnage converter via the splice by drawing the other of the first or second sheets of stock material into the dunnage converter.

A method of assembling a stock material unit for a dunnage conversion machine, the method comprising:
- providing a continuous sheet of foldable material defining a three-dimensional body, the continuous sheet including a tapered sheet section defined by a slanted fold and positioned adjacent to at least one face of the three-dimensional body;
- non-removably attaching a first portion of a connector of a splicing assembly to a portion of the tapered sheet section;
- and
- removably attaching a release layer to a second portion of the connector.

A method of splicing multiple stock material units for a dunnage conversion machine, the method comprising:
- folding a first sheet section of a first stock material unit away from a second sheet section, thereby exposing an adhesive side of a splicing connector that is attached to the first sheet section;
- positioning a second stock material unit against the first stock material unit, thereby splicing together the first stock material unit with the second stock material unit;
- and
- feeding a first section of the second stock material unit into the dunnage conversion machine, such that the second stock material will pull the first stock material into the dunnage conversion machine via the splicing connector to convert the multiple stock material units into dunnage.
