A tabletop converter has a conversion assembly that inwardly gathers and crumples a stock material to form a strip of dunnage. The conversion assembly includes a feeding assembly that moves the stock material and a controller that controls the feeding assembly to operate in both a forward direction and a reverse direction. To automatically separate a discrete dunnage product from the strip, a holder grabs and holds the strip of dunnage at a holding location downstream of the feeding assembly. The feeding assembly then operates in a reverse direction and urges the strip away from the holding location. This causes the strip to separate at or between the holding location and the feeding assembly, leaving a discrete dunnage product ready for use. The converter is mounted to a stand that allows the converter to rotate relative to part of the stand about both a horizontal axis and a vertical axis.

Cutterless dunnage converter and method

A dunnage conversion machine () and corresponding method for converting a supply of sheet stock material into a relatively less dense dunnage product includes a conversion assembly () that converts sheet stock material into a dunnage product, and a tension-adjusting assembly () having a sequence of transversely extending members () disposed upstream of the conversion assembly (). The transversely extending members () engage the stock material and help to prevent or to minimize excessive edge tension and/or the tearing associated therewith, while maintaining sufficient tension for proper tracking, especially for the conversion of single ply, lesser quality and/or short fiber paper, and/or otherwise improves or enhances the conversion process. The transversely extending members () are generally aligned end-to-end, and define a path for the stock material from a supply thereof, via a stock supply assembly () to the conversion assembly ().

Dunnage conversion machine and method

A motor-free dunnage conversion system comprises a housing () having a dispensing outlet () through which sheet stock material () can be pulled by a user to form a strip of dunnage. The housing () has a forming member () with circumferentially converging side walls that gradually inwardly gather and crumple the sheet stock material as it is pulled therethrough. The system can also include one or more of a stand having a support mounted thereto for supporting a supply of stock material, a repositionable member () supporting the forming member (), a guide member at the upstream end of the housing to guide the stock material from a supply to the forming member, and a catch device operative upon movement of the dunnage strip relative thereto to catch and hold the strip for severing a dunnage product therefrom.
