20170275036 · 2017-09-28 ·

The present disclosure is directed to an inflatable-cushion inflation and sealing device. The device includes an inflation assembly configured for insertion between first and second overlapping film plies. The inflation assembly includes a fluid conduit configured to direct a fluid in between the plies to form one or more cushions. The fluid conduit includes a nozzle. The inflation assembly includes a cutting member. The cutting member includes a blade holder with a blade and a blade guard mounted thereon. The blade guard has a safety position in which the blade is covered and a retracted position in which the blade is exposed. Installation of the blade holder onto the inflation assembly automatically positions the blade in the working position with the blade guard retracted. Removing the tray from the inflation assembly automatically positions the blade in the safety position by covering the blade with the blade guard.

DUNNAGE CUT-ASSIST BIASING MEMBER
20220227091 · 2022-07-21 ·

A conversion apparatus is provided herein. The conversion apparatus includes a cutting member having an edge configured for cutting the dunnage material. The conversion apparatus also includes a biasing member that is located adjacent to the cutting member such that the dunnage material passes between the biasing member and the cutting member. The biasing member operably contacts the dunnage material thereby biasing the dunnage material against the cutting member. The position of the biasing member relative to the cutting member is such that in response to the dunnage material being retracted back into the conversion apparatus the cutting member begins to sever the dunnage material, but in response to the dunnage material traveling in the dispensing direction the cutting member does not begin to sever the dunnage material due to the relative position.

Air cushion inflation machine

A machine for converting two different types of webs of inflatable material to two different types of inflated cushioning material includes an inflation arrangement, a sealing arrangement, and a tensioning device. The inflation arrangement is configured to provide air at a lower pressure to a first web of a first type of inflatable material to inflate the first type of inflatable material, and to provide air at a higher pressure to a second type of inflatable material to inflate the second type of inflatable material. The inflation arrangement includes a guide pin configured to the first and second webs and align the first and second webs on the machine. The sealing arrangement is configured to seal the first type of inflatable material and the second type of inflatable material to create the two different types of inflated cushioning material. The tensioning device is configured to provide a lower tensioning force to the first web as the first web moves between the inflation arrangement and the sealing arrangement, and to provide a higher tensioning force to the second web as the second web moves between the inflation arrangement and the sealing arrangement.

An insulated shipping container and method of forming and loading an insulated container utilizing sustainable materials including recycled post-industrial, pre-consumer natural fiber, plant-based fiber and synthetic fiber to include recycled polyethylene terephthalate (PET).

Apparatus for the production of a three-dimensional packaging material like a cushion product from a single- or multi-layer paper strip

An apparatus for the production of a three-dimensional packaging product, such as a cushion product, from a single- or multi-layer paper strip may include a preforming station deforming the paper strip to a three-dimensional packaging product with at least one crumple hollow space extending in the strip direction, and a rotation cutter following the preforming station in the feed direction of the paper strip, which is cutting a preformed paper strip to the desired length of the packaging product from a preformed paper strip. A cutting shaft on which a blade of the rotation cutter is mounted and a counter shaft on which the cutting pad is mounted may be included. A set-on element is mounted to the cutting shaft and/or the counter shaft for enlarging the flushing radial extension of the shaft and forming a flush profile channel wall section, the flushing profile course of the set-on element extending in the axial direction of the shaft to at least half of the width of the preformed paper strip section.

FORMING ASSEMBLY FOR A DUNNAGE CONVERSION MACHINE, DUNNAGE CONVERSION MACHINE AND PRE-PREPARED SHEET STOCK MATERIAL

A cushioning conversion machine converts a sheet stock material into a relatively lower-density cushioning dunnage product. An exemplary sheet stock material includes two sheets that each overlap a common side of another sheet and are connected to respective lateral edges of the other sheet. The conversion machine includes a forming assembly having a former for shaping and randomly crumpling the sheet material, a set of adjustable guide members to guide the crumpled sheet material to a feeding assembly downstream of the forming assembly, and a severing assembly downstream of the feeding assembly that separates discrete lengths of cushioning. The severing assembly includes a window frame passage that guides the crumpled sheet material to an outlet during operation of the feeding assembly and constrains the crumpled sheet stock material during operation of the severing assembly.

Dunnage conversion machine and method
11358362 · 2022-06-14 · ·

A dunnage conversion machine converts a sheet stock material into a dunnage product that is relatively thicker and less dense than the stock material. The conversion machine includes a conversion assembly that draws the sheet stock material therethrough and randomly crumples at least a portion of the sheet stock material. Before severing a discrete dunnage product of a desired length from the substantially continuous length of sheet stock material, the conversion assembly temporarily advances the sheet stock material therethrough while minimizing or eliminating the random crumpling of the sheet stock material in a reduced-crumpling zone, and then cuts the sheet stock material in the reduced-cutting zone to reduce or eliminate the production of scrap shards of sheet stock material.

Packing material and method of manufacturing the packing material

A packing material including a plurality of discrete cushioning elements and methods for making the same. The discrete cushioning elements may be cellulosic cushioning elements. A flexible linkage may connect the plurality of discrete cushioning elements in the packing material. The packing material may also include a bottom cellulosic sheet connected to a top cellulosic sheet with the plurality of cellulosic cushioning elements positioned between the top cellulosic sheet and the bottom cellulosic sheet. The packing material may also be a molded packing material that includes bonds comprising adhesive and cellulosic fibers. The adhesive and cellulosic fibers of the bonds may be dispersed between the folds of each of the cellulosic cushioning elements.

DUNNAGE CONVERSION MACHINE, METHOD, AND PRODUCT WITH A POLYGONAL CROSS-SECTION

A machine for converting a sheet material into a relatively less dense dunnage product includes a forming assembly and a feeding assembly downstream of the forming assembly. The forming assembly is configured to form the sheet material into a tubular shape with lateral edges of the sheet material adjacent one another. A deflector at a downstream end of the forming assembly is configured to engage the lateral edges of the sheet material and to urge the lateral edges into an interior of the tubular shape. This juxtaposes lateral edge portions of the sheet material adjacent the respective lateral edges. A forming channel at a downstream end of the forming assembly faces the deflector to receive the lateral edge portions and shape them into a tab. Finally, the feeding assembly includes rotating connecting members that engage and connect the overlapping lateral edge portions of the sheet material forming the tab.
