Various devices and methods for expanding and dispensing expandable slit sheet paper include a support member for a roll of expandable slit sheet paper. In some embodiments, the roll of expandable slit sheet paper has an interior core member and a roll of expandable slit sheet paper wound on said interior core member. The device preferably includes a tension device that is used to provide tension to resist rotation of the roll or the movement of the expandable slit sheet paper during use. The pressure of the tensioning device creates a friction required to enable the unexpanded slit sheet to be unwind and fed while simultaneously expanding.

In the preferred embodiments, the present invention provides substantially improved slit sheet cushioning products by advantageously combining novel paper properties with novel slit patterns for improved features and characteristics. In some illustrative and non-limiting example embodiments, cushioning products of the present invention can include, e.g., a novel slit sheet material in combination with extensible paper employed as, e.g., a cushioning pad or as cushioning within an envelope product, wherein the cushioning product can be substantially more resilient, but, yet, e.g., thinner for better utilization of space.

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.

According to some illustrative embodiments, a system and method is provided that includes, e.g., means for continuously conveying an assembly of layered sheets including a first paper sheet, at least one expanded sheet and a second paper sheet in a conveying flow between, e.g., a rotary mandrel or member at an upstream position in a direction of conveyance and a rotary die crushing and cutting tool, with said rotary mandrel or member and said rotary die crushing and cutting tool maintaining the at least one expanded sheet in an expanded state, said rotary tool having a crushing component that crushes a portion of the at least one expanded sheet such as to form a flap forming region of an envelope and a cutting component that cuts the assembly of layered sheets such as to separate individual envelope units.

Various embodiments of the present disclosure provide an improved edge protector having two plies wrapped around a core and a method of manufacturing the improved edge protector.

Stock material units that may be used in a dunnage conversion machine. For example, stock material units include sheet material that may be fed into the dunnage conversion machine and may be converted thereby into dunnage.

A drum covering for a drive drum (21) in a corrugating machine has a textile carrier material that reversibly shrinks when heated up, said carrier material being coated on at least one side with a coating material. Furthermore, it has two rectangular regions (71, 72) that are each connected to a convexly deltoid-shaped region (6) on a narrow side. Sets for producing the drum covering contain several covering pieces. A drive drum provided with the drum covering can be produced by the central axis (M) of the convexly deltoid-shaped region (6) being arranged along the circumferential central axis of the drive drum (21). Then, the convexly deltoid-shaped region (6) is fixed on the drive drum surface by means of at least one fixing element. The drive drum (21) is rotated, wherein the rectangular regions (71, 72) of the drum covering are wound around the drive drum (21) in a spiral-shaped manner. The rectangular regions (71, 72) are cut off on the ends of the drive drum (21) and the ends of the rectangular regions (71, 72) are fixed on the drive drum surface by means of further fixing elements. This drive drum can be installed in a corrugating machine in such a way that the rectangular regions (71, 72) are wound around the drive drum against the rotational direction of the drive drum (21) when the corrugating machine is in operation.

The presently disclosed subject matter generally relates to recyclable insulation material for shipping containers, groceries bags, etc., machines for making the recyclable insulation material, and methods for the making the recyclable insulation material. In one aspect, an insulation product may include a first layer and a first continuous paper sheet formed into a first plurality of flexible loops disposed on and attached to the first layer and defining a first plurality of air channels that extend in a direction that is substantially perpendicular with a machine direction of the insulation product. A take up factor of the first continuous paper sheet to the first layer may be greater than 1:1.

Stock material units that may be used in a dunnage conversion machine. For example, stock material units include sheet material that may be fed into the dunnage conversion machine and may be converted thereby into dunnage. The stock material unit includes one or more material sheets that form a three-dimensional body and a strap assembly wrapped about the three-dimensional body. The strap assembly includes a base sheet that defines a first face of the strap assembly, a reinforcement member secured to the base sheet and extending along at least a portion of a length thereof, and an adhesive securing a first end of the strap assembly to an opposite, second end of the strap assembly to retain the dunnage in the stock material unit configuration.
