SYSTEMS AND METHODS FOR MAKING ENVELOPES AND/OR OTHER PROTECTIVE PRODUCTS WITH EXPANDED PAPER CUSHIONING
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.
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.
An extensible slit sheet paper product is produced having an expandable slit pattern that forms open cells upon expansion of the paper product. The paper product is an extensible paper having an extensibility in the range from 1-9% in the machine direction and 1-5% in the cross direction. The expansion produces an array of hexagonal cells. The expanded extensible paper can be used to wrap an object for shipping by wrapping and cushioning the object in the expanded slit sheet material. The extensible, expandable slit sheet paper can be wrapped around itself to produce a void fill product.

B65D 85/672 - Containers, packaging elements or packages, specially adapted for particular articles or materials for web or tape-like material wound in flat spiral form on cores
In accordance with a broad embodiment of the invention, a novel paper product is comprised of two or more slit sheet packing material layers, each layer having its own slit pattern design to create interlocking layers of expansion sheet packaging materials. Each layer expands to create a three dimensional open netting of cells of hexagons, and the like, and is designed to have limited nesting with its opposing layer, thereby maximizing the thickness of the combined layers as compared to nested layers. Adjacent layers have differing slit patterns and can be expanded through expander type machinery such that the expansion rates of the differing slit pattern layers can be varied to deliver the same width of exiting expanded material from each layer. Preferably the differing slit pattern produce when expanded, inclined land areas that have the same number of rows per inch, but different angles of inclination of the land areas, such that adjacent layers can interlock, that is, have a restricted amount of nesting.

An expansion device includes an unexpanded slit sheet roll that is wound on a paper core that is longer than the width of the slit sheet paper roll. The paper core is placed onto a rod member. An adjustable downward pressure is exerted on the paper core and the paper core exerts pressure on the rod 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.

In accordance with a broad embodiment of the invention, a novel paper product is comprised of two or more slit sheet packing material layers, each layer having its own slit pattern design to create interlocking layers of expansion sheet packaging materials. Each layer expands to create a three dimensional open netting of cells of hexagons, and the like, and is designed to have limited nesting with its opposing layer, thereby maximizing the thickness of the combined layers as compared to nested layers. Adjacent layers have differing slit patterns and can be expanded through expander type machinery such that the expansion rates of the differing slit pattern layers can be varied to deliver the same width of exiting expanded material from each layer. Preferably the differing slit pattern produce when expanded, inclined land areas that have the same number of rows per inch, but different angles of inclination of the land areas, such that adjacent layers can interlock, that is, have a restricted amount of nesting.

Method and apparatus for dispensing and expanding expandable slit sheet material
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.

The paper core is placed into a yoke that holds the paper in position on each side of the unexpended slit sheet material. An adjustable downward pressure is exerted on the paper core and the paper core exerts pressure on the yoke. As the paper is pulled, this downward pressure creates the friction required to enable the unexpended slit sheet to be unwind and fed while simultaneously expanding. A blank sheet is formed into a box that stabilizes slit paper sheet wound around a core member.

Expandable slit sheet packaging material that interlocks when layered and expanded
In accordance with a broad embodiment of the invention, a novel paper product is comprised of two or more slit sheet packing material layers, each layer having its own slit pattern design to create interlocking layers of expansion sheet packaging materials. Each layer expands to create a three dimensional open netting of cells of hexagons, and the like, and is designed to have limited nesting with its opposing layer, thereby maximizing the thickness of the combined layers as compared to nested layers. Adjacent layers have differing slit patterns and can be expanded through expander type machinery such that the expansion rates of the differing slit pattern layers can be varied to deliver the same width of exiting expanded material from each layer. Preferably the differing slit patterns produce when expanded, inclined land area that have the same number of rows per inch, but different angles of inclination of the land areas, such that adjacent layers can interlock, that is, have a restricted amount of nesting.
