Abstract: 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.

Abstract: The present invention provides void fill dispenser systems and methods that highly effectively enable the easy and usable creation of void fill with expanded slit sheet paper in a manner unattainable in the existing art. According to some illustrative embodiments, a void fill dispenser is provided that advantageously dispenses unique void fill in a manner not previously possible. In some embodiments, the void fill dispenser is made with a recyclable material, such as, e.g., a corrugated box made from paper. In some embodiments, the void fill dispenser is made with metal and/or other rigid and/or non-recyclable materials. In some embodiments, the void fill dispenser can comprise an automated metal dispensing system that dispenses expanded slit sheet paper particularly for void fill in an automated manner.

Abstract: 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.

Abstract: Disclosed are a honeycomb cell shock-protection paper pad structure, and a fabrication method and a fabrication apparatus, for overcoming springing back of a stretched honeycomb cell paper shock-protection pad. The honeycomb shock-protection paper pad structure includes paper strips that have an unconnected site of which upper and lower ends are formed with folded-edge bend portions and a connected site that is formed with a central bend portion. A shape-fixing method includes stretching a cellular-form shock-protection paper pad for extension, bending upper and lower ends of the paper strips of the stretched honeycomb cell shock-protection paper pad toward one side, and conducting shape-fixing rolling with paired rollers. A shape-fixing apparatus includes a chassis portion, an edge scraper portion including flexible upper and lower scraper blades mounted obliquely on the chassis portion, and a shape-fixing roller portion including rigid shaping paired roller mounted on the chassis portion.
