Patent number: 9370914Abstract: 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.Type: GrantFiled: January 14, 2013Date of Patent: June 21, 2016Assignee: Ranpak Corp.Inventors: Raimond Demers, Erwin Riga, Dan Coppus, Patrick Klemke, Kristien Varrewaere

Publication number: 20160130104Abstract: An unpowered, manually operable apparatus for dispensing cushioning wrap material drawn concurrently from a roll of separator material and a self-contained cartridge that includes a roll of expandable sheet material. The rolls are supported on a stand for rotation about respective parallel, spaced-apart axes. In addition to the roll, the cartridge includes a tensioning assembly and support panels that abut respective ends of the roll. The tensioning assembly and the support panels cooperate with the stand to control rotational resistance of the roll. The rotational resistance causes the expandable sheet material to expand in length and thickness as it is manually pulled from the stand with the separator material, and support surfaces on the stand hold the cartridge and the separator roll in position. When the cartridge containing the expandable sheet material is depleted, the cartridge is readily removed and replaced.Type: ApplicationFiled: June 12, 2014Publication date: May 12, 2016Applicant: Ranpak Corp.Inventors: Brandon Page, Marcelo Passos
