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.
Claims25
A stock material unit for a dunnage conversion machine, comprising:
- a stock material sheet that forms a three-dimensional body;
- and
- a strap wrapped about the three-dimensional body as a closed loop and having:
- a load-spreading portion that has a first transverse width sufficient to distribute the weight of the three-dimensional body over the first transverse width to prevent or reduce damage to the three-dimensional body, wherein the first transverse width is less than a width of the three-dimensional body;
- a handle portion that has a second transverse width that is smaller than the first transverse width, the handle portion being formed without overlapping elements, and being sized such that the handle portion is graspable by a user's hand;
- a joining portion disposed on an opposite side of the handle portion from the load spreading portion and secured to the load spreading portion, thereby forming the closed loop, and
- wherein the load-spreading and handle portions are cooperatively configured to enable the three-dimensional body to be lifted from the handle portion.

A stock material unit for a dunnage conversion machine, comprising:
- a stock material sheet that forms a three-dimensional body;
- and
- a first strap and a second strap positioned on opposite sides of a center of gravity of the three-dimensional body, each strap wrapped about the three-dimensional body as a closed loop and having:
- a load-spreading portion that has a first transverse width sufficient to distribute the weight of the three-dimensional body over the first transverse width to prevent or reduce damage to the three-dimensional body;
- and
- a handle portion that has a second width that is smaller than the first width and is sized such that the handle portion is graspable by a user's hand;
- wherein the load-spreading and handle portions are cooperatively configured to enable the three-dimensional body to be lifted from the handle portion.

A method of assembling a stock material unit for a dunnage conversion machine, the method comprising:
- providing a three-dimensional body formed by a fanfolded stock material sheet that is configured for crumpling to convert the stock material sheet into dunnage by a dunnage conversion machine;
- and
- wrapping a strap about the three-dimensional body to position:
- a load-spreading portion of the strap extending around a plurality of corners of the three-dimensional body, the load-spreading portion having a first transverse width sufficient to distribute the weight of the three-dimensional body over the first transverse width at least at the plurality of corners to prevent or reduce damage to the three-dimensional body, wherein the first transverse width is less than a width of the three-dimensional body;
- a handle portion that has a second transverse width that is smaller than the first transverse width, the handle portion being formed without overlapping elements, and being sized such that the handle portion is graspable by a user's hand;
- and
- a joining portion disposed on an opposite side of the handle portion from the load spreading portion and secured to the load spreading portion, thereby forming the closed loop, and
- affixing ends of the strap to each other to secure the strap about the three dimensional body to enable the three-dimensional body to be lifted from the handle portion.
