摘要： A dunnage conversion machine includes a forming assembly configured to form a sheet stock material into a strip of dunnage, and a feeding assembly downstream of the forming assembly that is configured to pull the sheet stock material through the forming assembly. The machine also includes a tear assist assembly downstream of the feeding assembly that includes a pinch arm on one side of the path and a stop opposing the pinch arm on an opposite side of the path. The pinch arm is movable between a resting position in which the pinch arm is located on the one side of the path, and a pinching position in which the pinch arm is located in the path to capture the strip of dunnage between the pinch arm and the stop. Reversing the feed assembly while the pinch arm is in the pinching position causes the strip of dunnage to tear.

摘要： A dunnage conversion system for making a coil of dunnage from a sheet stock includes a coiler, a movable dancer upstream of the coiler and interposed in a path of the sheet stock, and a controller communicatively coupled to each of the coiler and the movable dancer. The coiler is configured to wind the sheet stock, and the controller is configured to control the speed of the coiler based on the position of the movable dancer to control tension of the sheet stock upstream of the coiler. The sheet stock drawn about the movable dancer may be a slit-sheet stock having a plurality of slits configured to expand under tension applied in a feed direction. The controller may be configured to control expansion of the slit-sheet stock upstream of the coiler allowing conversion of the sheet stock into a coil of relatively less dense dunnage prior to or during winding.

摘要： A coiler for producing tighter or smaller coils of dunnage uses a cam to move fork pins from a dunnage-receiving position inwardly to a more closely-spaced coiling position. The fork pins are coupled to pin mounts that cooperate with the cam and slots in a guide plate to move the parallel fork pins between the dunnage-receiving and coiling positions. The fork pins are mounted to extend perpendicular to and through the guide plate on opposing sides of a path of the dunnage to capture and wind a dunnage strip into a coil.

摘要： A dunnage conversion machine includes (i) a pair of gripping rollers configured to rotate at a first rotational speed to advance a slit-sheet material in a downstream direction; (ii) a pair of expansion rollers configured to rotate at a second rotational speed, faster than the first rotational speed, creating a stretching force on the slit-sheet material and further advancing the slit-sheet material, causing expansion of the slit-sheet material to a fully expanded state; and (iii) a pair of relaxation rollers configured to rotate at a third rotational speed, slower than the second rotational speed, reducing the stretching force and further advancing the slit-sheet material, allowing the slit-sheet material to relax to a partially expanded state. The pair of relaxation rollers (iii) also are configured to capture the slit-sheet material in the partially expanded state between a top cover sheet and a bottom cover sheet to form a dunnage pad.

摘要： A dunnage conversion system includes a machine for converting a stock material into a strip of relatively lower-density dunnage, a coiling mechanism for winding the strip into a coil, a taping mechanism for automatically securing a trailing end of the strip to the coil, and a coil ejecting mechanism for automatically removing the coil from the coiling mechanism. The taping mechanism includes a guide surface between an outlet of the machine and the coiling mechanism to guide the strip to the coiling mechanism and to guide tape for engagement with a trailing end of the strip and to secure the trailing end of the strip to the coil. The coil ejecting mechanism includes a lever arm that pivots to push the completed coil off the coiling mechanism.

摘要： A manually-operated dunnage conversion apparatus includes a housing with an outlet opening, a supply of slit sheet stock material supported within the housing for dispensing from the outlet opening, and a pair of opposed expansion members rotatably coupled to the housing for rotation about respective, parallel expansion axes between the supply and the outlet opening. The expansion members are biased towards each other via a biasing member to provide a gripping force on sheet stock material fed therebetween to apply friction to the sheet stock material that causes the sheet stock material to expand in length and thickness as an operator pulls the sheet stock material from the outlet opening in the housing. With the possible exception of the biasing member, the apparatus may be made of paper-based products, making the apparatus recyclable, reusable, and composed of a renewable resource, as well as inexpensive to manufacture.

摘要： A machine for converting a sheet material into a relatively less dense dunnage product includes a forming assembly and a feeding assembly downstream of the forming assembly. The forming assembly is configured to form the sheet material into a tubular shape with lateral edges of the sheet material adjacent one another. A deflector at a downstream end of the forming assembly is configured to engage the lateral edges of the sheet material and to urge the lateral edges into an interior of the tubular shape. This juxtaposes lateral edge portions of the sheet material adjacent the respective lateral edges. A forming channel at a downstream end of the forming assembly faces the deflector to receive the lateral edge portions and shape them into a tab. Finally, the feeding assembly includes rotating connecting members that engage and connect the overlapping lateral edge portions of the sheet material forming the tab.

摘要： A conversion assembly for a dunnage conversion machine includes both a downstream pair of rotatable members and an upstream pair of rotatable members upstream of the downstream rotatable members. The downstream rotatable members include a pair of gears, and each gear has a plurality of teeth and is rotatable about a respective axis. The gears are positioned so that the teeth of one gear are sequentially interlaced with the teeth of the other gear as the gears rotate. The upstream rotatable members include a pair of feed wheels, and the gears and the feed wheels define a path for a sheet stock material from between the upstream pair of feed wheels to between the downstream pair of gears. The rate at which the sheet stock material is advanced by the feed wheels is the same as the rate at which the sheet stock material is advanced by the gears.

摘要： A bundle of packing material includes at least two strips of packing material folded into a compact configuration. The strips of packing material include a top strip having a length dimension between first and second end portions and a central portion between the first end portion and the second end portion, and a bottom strip having a length dimension between first and second end portions and a central portion between the first end portion and the second end portion. The central portion of the top strip overlays the central portion of the bottom strip and the length dimension of the top strip is oriented orthogonal to the length dimension of the bottom strip. The first and second end portions of top strip are folded over the central portions, and the first and second end portions of the bottom strip are folded over the central portions.

摘要： A packaging method includes the steps of (a) detecting whether a height (104) of contents (105) in a container (106) exceeds a predetermined height (112), and (b) indicating how much dunnage to dispense based on predetermined criteria, including whether a detected height exceeds a predetermined height that is less than a height of the container. The indicating step includes indicating a quantity of dunnage to dispense selected from a plurality of predetermined quantities of dunnage. If no detected height is greater than the predetermined height, the indicating step includes indicating that a regular amount of dunnage should be dispensed. And if a detected height is greater than the predetermined height, the indicating step includes indicating that either zero or less than the regular amount of dunnage should be dispensed. The detecting step also can include detecting whether any contents in the container have a height above the height of the container.
