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.

The present disclosure relates generally to an inflation and sealing machine and in particular to a method for modifying one or more parameters of the machine. The method includes identifying a configuration of a supply material to be used with the inflation and sealing machine, such as by receiving a user input, automatically detecting characteristics of the material, and/or receiving data such as from a sensor regarding the characteristics of the material. Once the configuration of the supply material is identified, the method includes receiving a selection of a prestored recipe according to a configuration of the supply material, where the recipe determines or sets the value for one or more operating parameters of the machine.

Dispenser with bearings for dispensing a roll of tension activated expandable sheet material, as well as methods for using the same.

A dunnage conversion system includes a machine for converting a stock material into a strip of relatively lower-density dunnage, a coiling mechanism for winding the strip into a coil, a taping mechanism for automatically securing a trailing end of the strip to the coil, and a coil ejecting mechanism for automatically removing the coil from the coiling mechanism. The taping mechanism includes a guide surface between an outlet of the machine and the coiling mechanism to guide the strip to the coiling mechanism and to guide tape for engagement with a trailing end of the strip and to secure the trailing end of the strip to the coil. The coil ejecting mechanism includes a lever arm that pivots to push the completed coil off the coiling mechanism.

A device (1) for dispensing a cushioning and packaging element from at least one strip of paper includes at least two guides (2) around which at least one strip of paper is wound. The device (1) also includes at least one drive element for driving the at least one strip of paper. The device (1) further includes at least one creasing device (4) for creasing the at least one strip of paper. The guides (2) extend beyond the at least one creasing device (4), downstream of the at least one creasing device (4).

A machine includes an inflation arrangement, a sealing arrangement, and a tensioning device. The inflation arrangement provides air at a first pressure to inflate a first web of a first type of inflatable material, provides air at a second pressure to inflate a second web of a second type of inflatable material, receives the first and second webs, and aligns the first and second webs on the machine. The first pressure is different from the second pressure. The sealing arrangement seals the first and second types of inflatable material. The tensioning device provides a first tensioning force to the first web as the first web moves between the inflation and sealing arrangements and provides a second tensioning force to the second web as the second web moves between the inflation and sealing arrangements. The first tensioning force is different from the second tensioning force.

An apparatus for manufacturing a packaging product from a packaging-material web may include a production device for making the packaging-material web; a drawing device for drawing the packaging-material web off from a packaging-material source; a deforming device for deforming the packaging-material web; a removal conveying device for removing the packaging-material product from the apparatus; and/or a dispensing device for dispensing the packaging-material product in an aligned manner; and using a module interface, via which at least one of the functional units, forming a structural unit, can be connected in a releasable manner to an adjacent functional unit upwards and/or downwards in the conveying direction and/or changed over therewith.

The disclosure relates to padding articles comprising a cancellous body formed from an agglomeration of grains made from a polymer material and are bonded together in a cancellous structure. The padding articles provide thermal insulation, sound insulation, cushioning, or a combination thereof. The disclosure also relates to container systems that include the padding articles, apparatuses/methods for manufacturing the padding articles, and methods of use thereof.

A packaging material including one or more expandable layers that provide protection to contents of a packaging enclosure formed with the packaging material. The packaging material includes at least a first layer and a second layer bonded to one another. The first layer is pulled or extended in a first direction that is effective to cause the second layer to expand in a second direction. The second layer is a cut-patterned layer which creates structural strength in the packaging material when expanded.

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.
