A supply of single-ply, fan-folded sheet stock material includes a holder that facilitates simultaneously loading multiple plies of sheet stock material into a dunnage conversion machine for conversion into a dunnage product. The holder has inclined support surfaces and intersecting support walls that support the support surfaces in their inclined orientations. The holder has a W-shape cross-section, with inclined outer support surfaces and inclined inner support surfaces that may meet in the middle. The inner support surfaces generally are perpendicular to adjacent outer support surfaces to support a generally rectangular stack and sub-stacks of single-ply, fan-folded sheet stock material. The inclined support surfaces of the holder facilitate splitting the stack in half and supporting the two sub-stacks so that pages on top of the two stacks, connected by a center fold line, can be drawn into the conversion machine simultaneously.

An apparatus for the production of a cushion product from a single or multi-layer continuous paper strip includes a chute-like preforming station for the compression of a paper strip in the transverse direction and a deformation station following the preforming station in the feed direction of the paper strip having two embossing rollers engaging into each other in a deformation area in order to form the paper strip to a cushion product with at least one crumple hollow space extending in the longitudinal direction. The preforming station has a lifting unit and is positioned upstream in the feed direction of the embossing rollers for lifting a central area of the paper strip.

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.

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.

An apparatus for the manual or machine production of a tube-like packaging material from a paper supply unit, such as a paper strip wound up to a roll, includes a roll longitudinal axis and forming an inner hollow space, or a paper strip folded to a Leporello stack defining an upper side, from which the paper strip is drawable for forming the packaging material. A guiding chute has an opening for ejecting the packaging material from a paper supply unit arranged in an ejection position. The guiding chute has an inner contour narrowing in an ejection direction towards an opening. A receiving arrangement, such as a tube magazine, encompasses at least one paper supply unit at least partly circumferentially with paper supply units arranged sequentially behind each other, wherein the apparatus having a movable transport, such as a slide, for displacing at least the at least one paper supply unit in the ejection direction.

A supply of single-ply, fan-folded sheet stock material (100) includes a holder that has inclined support surfaces (114, 116, 120, 122) and intersecting support walls (124, 126) that support the support surfaces in their inclined orientations. The holder has a W-shape cross-section, with inclined outer support surfaces (114, 116) and inclined inner support surfaces (120, 122) that may meet in the middle. The inner support surfaces generally are perpendicular to adjacent outer support surfaces to support a generally rectangular stack (102) and sub-stacks (110, 112) of single-ply, fan-folded sheet stock material. A method includes laying open a stack of single-ply fan-folded sheet stock material to form two sub-stacks of sheet stock material and operating a dunnage conversion machine to simultaneously draw sheet stock material from both sub-stacks of sheet stock material, thereby providing a two-ply sheet stock material for conversion into a dunnage product.

A dunnage conversion system (100) includes a supply area (120), a dunnage conversion machine (110), and an arcuate slot (130). The supply area (120) is configured to hold a supply of a sheet material (122). The sheet material (122) is in a substantially flat configuration in the supply area (120). The dunnage conversion machine (110) is configured to pull the sheet material (122) from the supply area (120) and to convert the sheet material (122) into a non-flat configuration. The arcuate slot (130) is positioned between the supply area (120) and the dunnage conversion machine (110) such that the sheet material (122) is fed through the arcuate slot (130) as the sheet material (122) passes along a path from the supply area (120) to the dunnage conversion machine (110).

A stock supply assembly for a dunnage conversion machine includes a stock material support having a support structure, such as a shelf for a stack of fan-folded sheet stock material. The stock supply assembly is rotatable between a relatively lower loading position and a relatively higher operating position vertically displaced relative to the loading position.

A protective packaging formation device is disclosed herein. The device includes an inflation assembly that directs fluid between first and second overlapping plies of a web material. The device also includes a sealing mechanism. The sealing mechanism includes a heating zone and a cooling zone. The sealing mechanism also includes a heating element that extends along both the heating zone and the cooling zone, with the heating element having a first profile in the heating zone and a second profile in the cooling zone.
