Publication number: 20240255839Abstract: A wire suspended screen includes a roller assembly and a screen assembly. The roller assembly includes an inner tube and a plurality of sleeves partially extending around the inner tube, defining a longitudinal recess along the roller. The sleeves are spaced apart, defining gaps. Wires are attached to the inner tube and wind over the outer surface of the inner tube in the gaps. The wires are attached to an upper slat of the screen assembly. As the roller is rotated, the wires wind and unwind from the inner tube to raise and lower the screen assembly, depending on the direction of rotation. When the screen assembly is raised, the upper slat fits into the longitudinal recess. As the screen is raised further, the screen assembly winds over the exterior surface of the sleeves and upper slat. The roller can be motor driven.Type: ApplicationFiled: May 31, 2022Publication date: August 1, 2024Inventors: Ron Knutson, Erwin Riga, Bert van Dinther

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

Patent number: 7722519Abstract: A dunnage conversion machine (10) and corresponding method for converting a supply of sheet stock material into a relatively less dense dunnage product includes a conversion assembly (20) that converts sheet stock material into a dunnage product, and a tension-adjusting assembly (26) having a sequence of transversely extending members (28) disposed upstream of the conversion assembly (20). The transversely extending members (28) 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 (28) are generally aligned end-to-end, and define a path for the stock material from a supply thereof, via a stock supply assembly (15) to the conversion assembly (20).Type: GrantFiled: August 22, 2005Date of Patent: May 25, 2010Assignee: Ranpak CorporationInventors: Mike J. Timmers, Jos Saive, Dan Coppus, Raimond Demers, Erwin Methorst, Erwin Riga

Publication number: 20090325773Abstract: A motor-free dunnage conversion system comprises a housing (20) having a dispensing outlet (40) through which sheet stock material (34) can be pulled by a user to form a strip of dunnage. The housing (20) has a forming member (44, 50) 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 (22) supporting the forming member (44, 50), 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.Type: ApplicationFiled: September 8, 2009Publication date: December 31, 2009Applicant: RANPAK CORP.Inventors: Robert C. Cheich, Hubertus Y.M Cals, Erwin Riga, Donald Gorg, Daniel L. Carlson, Shawn Baiers, Edward S. Martis, Jr., Carrie A. Schlegel
