摘要： A jam-sensing method for a dunnage conversion machine includes the following steps: (a) converting a stock material into a relatively less dense dunnage material having characteristics that vary along the length of the dunnage material; (b) sensing the characteristics of the dunnage material; (c) generating a signal that varies as a function of the sensed characteristics; (d) monitoring the generated signal over time; and (e) generating a control signal when variation in the generated signal within a predetermined period is less than a predetermined amount, which would indicate a lack of movement of the material. This control signal can used to shut down the conversion process, thereby minimizing the extent of the jam condition.

摘要： A dunnage conversion system (20) for expanding an unexpanded slit sheet stock material (23) to form an expanded dunnage product (26). The dunnage conversion system includes a converging chute (28) to inwardly gather laterally-extending edges of sheet stock material towards one another, causing random crumpling of the sheet stock material to form a modified ply. The conversion system also includes feed wheels (120) that advance the modified ply through the converging chute and pinch rollers (122) that cooperate with the feed wheels to expand the modified ply traveling between the feed wheels and the pinch rollers to form a dunnage product. The expanded dunnage product is expanded both in a longitudinal feed direction and in thickness as compared to the unexpanded slit sheet stock material, and thus is a three-dimensional product having increased volume and lower density per unit of length as compared to the unexpanded slit sheet stock material.

摘要： A dunnage conversion machine includes a bunching assembly that randomly crumples at least two plies of sheet stock material into modified plies having a relatively thicker three-dimensional shape, and a feeding assembly that advances and connects together longitudinally-extending portions of the modified plies to form a dunnage strip. A diverter minimizes overlap of and encourages separation of lateral edges of the modified plies from one another, and a severing assembly severs distinct dunnage products from the strip. An exemplary resultant dunnage product includes two or more plies of crumpled sheet material interconnected along a longitudinally-extending portion having interconnected overlapped portions of each of the plies and a longitudinally-extending line of connection. Each ply may extend laterally outwardly along randomly crumpled edge portions having a crumpled lateral width greater than a lateral width of the longitudinally-extending portion, the edge portions extending from the line of connection to opposed, laterally-extending free edges.

摘要： A dunnage conversion machine (36) converts a sheet stock material into a dunnage product that is relatively thicker and less dense than the stock material, but is relatively thin and sufficiently flexible to function as a protective wrap. The conversion machine includes a feed mechanism (40) that advances a sheet stock material therethrough and a connecting mechanism (42) downstream of the feed mechanism. The connecting mechanism retards the passage of the sheet stock material therethrough by feeding the stock material therethrough at a slower rate than the feed mechanism feeds the stock material to the connecting mechanism. This causes the stock material to randomly crumple in a longitudinal space between the feed mechanism and the connecting mechanism.; The connecting mechanism connects multiple overlapping layers of sheet stock material together as they pass therethrough, including connecting at least one crumpled sheet to one side of one other sheet.

摘要： A method of converting a sheet stock material into a relatively less dense dunnage product includes the step of supplying the sheet stock material to a conversion mechanism for converting the sheet stock material into the dunnage product by permanently deforming the sheet stock material into a nonplanar configuration to provide the dunnage product with a density less than the density of the stock material from which it is formed. The sheet stock material comprises one or more plies of paper having a caliper no less than about 3.5 points (about 0.089 millimeter) or a bulk caliper no less than about 3.4 points (about 0.086 millimeter) for a basis weight no greater than about 32 pounds (about 86 grams per square meter) and when a moisture content is no greater than about 10%.
