Publication number: 20130316151Abstract: A dunnage conversion machine (36) converts a sheet stock material into a dunnage product that is relatively thicker and less dense than the stock material, but is relatively thin and sufficiently flexible to function as a protective wrap. The conversion machine includes a feed mechanism (40) that advances a sheet stock material therethrough and a connecting mechanism (42) downstream of the feed mechanism. The connecting mechanism retards the passage of the sheet stock material therethrough by feeding the stock material therethrough at a slower rate than the feed mechanism feeds the stock material to the connecting mechanism. This causes the stock material to randomly crumple in a longitudinal space between the feed mechanism and the connecting mechanism. The connecting mechanism connects multiple overlapping layers of sheet stock material together as they pass therethrough, including connecting at least one crumpled sheet to one side of one other sheet.Type: ApplicationFiled: August 2, 2013Publication date: November 28, 2013Applicant: RANPAK CORP.Inventors: Robert C.

Publication number: 20130296154Abstract: A dunnage conversion machine provides an improved electronic monitoring and control system for detecting and resolving many jamming conditions before they require significant operator intervention. The machine includes a conversion assembly with a feeding device that feeds the sheet stock material through the machine, and a sensing device downstream of the feeding device to monitor movement of the stock material downstream of the feeding device and to output a corresponding signal. A controller controls operation of the feeding device in response to the signal from the sensing device. The controller uses the signal to detect a potential jam condition and controls the feeding device to prevent or minimize the occurrence or severity of the jam condition, thereby minimizing the amount and degree of required operator intervention.Type: ApplicationFiled: June 13, 2012Publication date: November 7, 2013Applicant: RANPAK CORP.Inventor: Jiri G.

Patent number: 8568128Abstract: An apparatus for shaping packaging material, comprising a housing support including hopper, a packaging material reservoir, a discharge orifice, and a bearing structure therebetween defining a continuous feeding path for the packaging material. The feeding path includes an interior wall continuously extending around an axis of the material's feeding direction. The housing support further includes at least one concavity in the bearing structure extending laterally away from the feeding path, the concavity having a portion within the feeding path at a slit formed within the interior wall, the concavity holding a shaping device that is rotatably mounted on the bearing structure and partially projects from the slit into the feeding path, the shape of the slit being complementary to the shape of a section of the shaping device adjoining the slit such that a tolerance gap is formed allowing the shaping device to rotate relative to the bearing structure.Type: GrantFiled: May 29, 2009Date of Patent: October 29, 2013Assignee: Sprick GmbH Bielefelder Papier-und Wellpappenwerke & Co.Inventors: Stefan Sprick-Schütte, Oliver Schmidt

Patent number: 8550971Abstract: Methods, apparatus and systems for producing cushioning material from sheet material. In some embodiments, the apparatus comprises horizontally aligned forming members having fins for use in pulling and processing sheet material. The sheet material can be perforated sheet material. A holder can be provided for holding sheet material in stock roll form, the holder having a cross-bar for producing resistance against the stock roll to dissipate momentum of the stock roll when the motor of the apparatus is stopped.Type: GrantFiled: June 19, 2012Date of Patent: October 8, 2013Assignee: Nuevopak Technology Company LimitedInventors: Simon C. S. Chan, Shek Wah Hau

Publication number: 20130237398Abstract: A dunnage-producing system includes a dunnage conversion machine for converting a stock material into a relatively less dense dunnage product, a supply of stock material, and a guide element. The conversion machine is rotatable about a substantially vertical axis. The supply of stock material includes a support for the stock material that is movable relative to the conversion machine, such as for replenishing the stock material. The guide element is rotatable with the conversion machine to maintain a consistent position relative to the conversion machine, thereby consistently positioning the support relative to the conversion machine to avoid tearing or jamming problems associated with an improperly aligned supply of sheet stock material.Type: ApplicationFiled: November 14, 2011Publication date: September 12, 2013Applicant: RANPAK CORP.Inventors: Edward W. Lintala, Carrie Schlegel

Publication number: 20130196839Abstract: A compact dunnage conversion machine includes a converging chute with a restricted inlet, a powered feed assembly with a sealed gearbox, a plurality of interchangeable power supplies, and a restricted outlet chute. The converter can convert a sheet stock material into dunnage for use in packaging one or more objects in a container. The restricted inlet and outlet make it more difficult for foreign objects to enter the converter and disrupt the conversion process. The sealed gearbox interposed between the driving elements of the feed assembly and an electric motor facilitates maintenance and repair of the feed assembly, while also protecting the gears therein. Finally, the power supplies provide electrical power to the motor and can include an electrical storage device, such as a battery, or an alternating-current-to-direct-current converter which is connectable to a source of electricity for supplying that electricity to the motor in an acceptable form.Type: ApplicationFiled: March 15, 2013Publication date: August 1, 2013Applicant: RANPAK CORP.Inventor: Ranpak Corp.

Publication number: 20130178351Abstract: A dunnage crumpling apparatus is provided having first and second entry-side crumpling members and first and second exit-side crumpling members. The first and second entry-side crumpling members define an entry therebetween. The first and second exit-side crumpling members define an exit therebetween that is disposed along the longitudinal path downstream of the entry. A crumpling zone being defined between the entry and exit. The first entry-side rumpling member is configured for moving at an first rate and is associated with the second entry-side crumpling member for moving sheet material through the entry in a first direction along a longitudinal path at an entry rate. The first exit-side crumpling member is configured for moving at an second rate and is associated with the second exit-side crumpling member for moving the sheet material through the exit in the first direction along the path at a exit rate that is slower than the entry rate to crumple the sheet material for producing dunnage.Type: ApplicationFiled: March 4, 2013Publication date: July 11, 2013Applicant: Pregis Innovative Packaging, Inc.Inventor: Pregis Innovative Packaging, Inc.

Publication number: 20130130882Abstract: 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: ApplicationFiled: January 14, 2013Publication date: May 23, 2013Applicant: RANPAK CORP.Inventor: Ranpak Corp.
