Abstract
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.
