摘要： A device for expanding and dispensing expandable slit sheet paper includes a pair of support members for a roll of expandable slit sheet paper. 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 interior core member has an axial length that is greater than the width of said slit sheet paper that is wound on said interior core member and has end regions that extend beyond the roll of expandable slit sheet paper. Pressure means is provided for pressing a first end region against its core support member and applying a frictional rotation resistance to the core member end region. The roll of expandable slit sheet paper is mounted on the device by positioning one end region under the pressure means and in a support relationship with its core support member while the roll of expandable slit sheet paper is inclined with respect to the device. The other end region is then moved into its supported position with its core support member. An adjustable downward pressure is exerted on the paper core end region and causing the paper core end region to be pressed against its support member as the paper is pulled. The downward pressure creates the friction required to enable the unexpanded slit sheet to be unwind and fed while simultaneously expanding.

摘要： A drive system is configured to feed a sheet material. The drive system includes a first roller and a second roller. A circumference of the first roller has a first curved profile. A circumference of the second roller has a second curved profile. The first and second rollers are arranged such that, when the sheet material is not located between the first and second rollers, the first curved profile of the first roller contacts the second curved profile of the second roller. The first and second rollers are further arranged such that, when the sheet material is located between the first and second rollers, rotation of at least one of the first and second rollers causes the sheet material to be fed through the drive system.

摘要： A dunnage conversion apparatus for dispensing a cushioning wrap material from a roll of expandable slit sheet material is described. The roll of expandable slit sheet material includes an expandable slit sheet material in an unexpanded state. The expandable slit sheet material is pulled from the roll of expandable slit sheet material and expanded to a pre-expanded state and an expanded state. To expand the expandable slit sheet material and form the cushioning wrap material, a stretching force is applied to the expandable slit sheet material in a stretching direction as it is pulled from the roll of expandable slit sheet material. Accordingly, the dunnage conversion apparatus includes a tensioning device for assisting in the application of such stretching force.

摘要： The present invention provides void fill dispenser systems and methods that highly effectively enable the easy and usable creation of void fill with expanded slit sheet paper in a manner unattainable in the existing art. According to some illustrative embodiments, a void fill dispenser is provided that advantageously dispenses unique void fill in a manner not previously possible. In some embodiments, the void fill dispenser is made with a recyclable material, such as, e.g., a corrugated box made from paper. In some embodiments, the void fill dispenser is made with metal and/or other rigid and/or non-recyclable materials. In some embodiments, the void fill dispenser can comprise an automated metal dispensing system that dispenses expanded slit sheet paper particularly for void fill in an automated manner.

摘要： A packing machine and a method of use thereof for packing articles in airbags. The packing machine includes three consecutive stations that can receive airbags in a series of airbags one by one, wherein the article to be packed is placed in the airbag. The first station can receive a new bag containing the article. In the first station, the airbag can be horizontally sealed at the top to close the opening and can then be inflated. In the second station and the third station, the airbag can be vertically sealed and can then be dropped into a conveyor at the end of the third station. An air tube that extends between the first station and the second station can be used to inflate the airbags. Two linear actuators with gripping heads can move the airbags from between stations, and break the leading airbag from the series of airbags.

摘要： 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.
