A packing product, its use, a machine for production of the packing product, and a method of manufacture, creates a double curl, “B” or modified “B” having elastic, cushioning, form-fitting, and coherent packing properties. The “B” is created from a dimension-controlled strip of preferably, but not necessarily, cohesive paper having a cohesive side and a non-cohesive side, a leading end, and a trailing end. The leading edge is wound into a spiral in a first direction with the cohesive side of the dimension-controlled cohesive paper facing outward, while the trailing edge is wound into a spiral in a second direction that is opposite the first direction, with the cohesive side of the cohesive paper also facing outward. A plurality of “B”s provide a clumped, cohesive mass around a packed item. The machine can produce “B”s of various sizes to accommodate various sized items and/or packaging.

According to some illustrative embodiments, a protective product is provided that includes: at least one expandable slit paper sheet, said at least on expandable slit paper being expanded between opposing ends of said slit paper; a first embossed paper sheet facing said expanded slit paper sheet and a second paper sheet facing an opposite side of said at least one expanded slit paper sheet, at least one of said first embossed paper sheet and said second paper sheet being fixed to said expanded slit paper sheet at the opposing ends of said expanded slit paper sheet and thereby maintaining said expanded paper in its expanded state, said first embossed paper sheet having a plurality of embossings that increase the rigidity of said embossed paper sheet, whereby inhibiting deformation of said embossed paper sheet that is fixed to said expanded slit sheet paper.

A method and system for forming domes or protruded structures in a flat material such as paper is disclosed. The method includes cutting one or more sheets; applying an adhesive between the one or more sheets, joining the one or more sheets together in a registered manner to form a substrate, encapsulating the one or more sheets in a container to prevent curing of the adhesive, opening the container, and pressing the adhesive under pressure to shape the substrate into a desired shape may include the domes or protruded structures.

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.

A method for production of a female embossing tool (6) intended for embossing a sheet element (60): provide a female embossing tool (6) with an outer layer (44) made of a material with shape-memory type properties, and the outer face of the layer has no recesses; provide a male embossing tool (5, 5′) with an outer face with at least one protuberance corresponding to at least one desired embossing relief that is to be formed on the sheet element (60) after embossing; and cooperation of the male embossing tool (5, 5′) with the female embossing tool (6) such that the outer layer (44) of the female embossing tool (6) undergoes a plastic deformation which creates at least one recess (42, 42′) of a shape complementary to the protuberance(s) (41, 41′) of the male embossing tool (5, 5′).

An apparatus for supplying a coil-like padding product for packaging purposes comprises a supply device for supplying a web-type padding material and also a rolling-up apparatus, which rolls up the web-type padding material to form the coil-like padding product. It is proposed that the rolling-up apparatus should comprise a flexible delimiting means, which can form an at least partially curved delimiting wall of an at least temporarily present rolling-up space, of which the extent is preferably alterable and which has an inlet for the web-type padding material, it being possible for the web-type padding material to enter into the rolling-up space through said inlet, wherein the web-type padding material is guided by the at least partially curved delimiting wall, this resulting in the formation of the coil-like padding product.

The invention concerns an elongated protective corner for the transport and/or packaging of products. The corner has at least two non-corrugated paperboard plies combined together to create two perpendicular wings and an apex. The plies form multiple ply sections, and at least one of the ply sections of a given ply overlaps another ply section of the same ply. This overlapping arrangement gives the apex a resistance force of about 100 to about 500 lbs. The thickness of the corner can vary, with each wing being in the range of about 100 to about 250 points, and each ply is made from paperboard having a grammage of about 120 to about 380 g/m.sup.2. The resistance force can be determined by mounting the corner upon two blocks, and applying a force to the apex at a middle of the corner until a fracture is detected.

A computer system for creating custom-made corrugated edge protectors receives one or more product protection variables. The system also determines one or more corrugated edge protector attributes based upon the one or more product protection variables. Additionally, the system generates a construction command that is configured to cause a packaging production machine to create a custom-made corrugated edge protector. The system also sends the construction command to the packaging production machine. The construction command causes the packaging production machine to create the custom-made corrugated edge protector.

A method for production of a female embossing tool intended for embossing a sheet element: provide a female embossing tool with an outer layer made of a material with shape-memory type properties, and the outer face of the layer has no recesses; provide a male embossing tool with an outer face with at least one protuberance corresponding to at least one desired embossing relief that is to be formed on the sheet element after embossing; and cooperation of the male embossing tool with the female embossing tool such that the outer layer of the female embossing tool undergoes a plastic deformation which creates at least one recess of a shape complementary to the protuberance(s) of the male embossing tool.

An apparatus for the production of a three-dimensional packaging product, such as a cushion product, from a single- or multi-layer paper strip may include a preforming station deforming the paper strip to a three-dimensional packaging product with at least one crumple hollow space extending in the strip direction, and a rotation cutter following the preforming station in the feed direction of the paper strip, which is cutting a preformed paper strip to the desired length of the packaging product from a preformed paper strip. A cutting shaft on which a blade of the rotation cutter is mounted and a counter shaft on which the cutting pad is mounted may be included. A set-on element is mounted to the cutting shaft and/or the counter shaft for enlarging the flushing radial extension of the shaft and forming a flush profile channel wall section, the flushing profile course of the set-on element extending in the axial direction of the shaft to at least half of the width of the preformed paper strip section.
