摘要:
The present invention involves an apparatus and a method of making slotted tubular dunnage. The method of the present invention includes providing a tube having a pair of flanges at opposite sides extending along the length of the tube, and holding the tube by gripping the flanges at opposite sides of the tube and squeezing sides of the tube together. The method further includes moving the tube into a slotting position between a steel rule die and a kissing plate while holding the tube with the sides squeezed together. The method further includes shifting the die against and through the sides of the tube forming a slot therein surrounding a cutout slug of the tube. The method further includes withdrawing the die from the tube while retaining the slug within the slot. Furthermore, the method includes moving the tube to a discharged position and discontinuing the squeezing of the tube.

A formed piece comprises a substantially cylindrical outer surface layer of sheet material extending along a longitudinal axis of the formed piece from a first end to a second end of the formed piece, and inner layers of sheet material within the outer surface layer randomly arranged and creating air gaps between at least a portion of the inner layers. The surface layer and inner layers of sheet material are twisted around the longitudinal axis of the formed piece and along the length of the longitudinal axis.

The present invention relates of a method and apparatus for making an improved resilient packing material by forming, resiliently folding and crimping shredded strips of moistened paper material into an improved interlocking, bulk, packaging material. The method and apparatus includes a wetting or dampening system which can be selectively varied to regulate the moisture content of moistened paper material.

Flowable loose packing dunnage is formed from paperboard into three dimensional particles of various shapes. Also, an apparatus for forming the dunnage employs two vertically aligned arrays of toothed, untoothed and/or cutting wheels through the nip of which paperboard segments pass and by which they are shaped into dunnage particles. Further, in a method of forming the dunnage particles, strips of paperboard are cut into segments which are formed into three dimensional shapes. A method of protecting a packed object surrounds it with the flowable loose packing dunnage made of paperboard in accordance with the present invention.

A void fill material (10) can be formed from ordinary scrap cardboard into an interlocking packaging material. Each piece of the material (10) has a primary section (20) defining a primary plane. The void fill has at least two limbs extending from the primary section. The void fill can be in any geometric shape, such as a block Y (10), a block H (62), an angled Y (80), an X (100), and a cross (120). Scoring can be applied to the void material at any location, thereby facilitating the deformation of the void fill.

Apparatus for fabricating discrete segments of cushioned web material for use as dunnage. The apparatus includes a mobile supply cart having at least one substantially horizontal support arm for receiving the hollow core of rolled web material. The apparatus also includes a separate driven rugation device with feed rollers for directing multiple plies of the web material in overlying, contacting relationship along a single path of travel. The separate cart and rugation device may be removably interconnected for lateral alignment. Driven interdigitized texturing rolls downstream of the feed rollers emboss a raised pattern on the web material, and a plurality of separating rollers downstream from the texturing rolls separate the plies of web material and direct them in divergent paths of travel. Combining rolls recombine the plies of textured web material such that the embossed areas of each ply do not directly overlie each other but are offset, creating void areas between the adjacent plies. A driven cutter downstream of the combining rolls severs the recombined offset embossed plies into discrete segments. The cutter may have a rotating disc blade with a peripheral edge which moves transverse to the longitudinal length of the plies to cut the plies. Last, driven exit rollers convey the cut segments of material from the rugation device.

A void fill material (10) can be formed from ordinary scrap cardboard into an interlocking packaging material. Each piece of the material (10) has a primary section (20) defining a primary plane. In a preferred embodiment, a first, second and third finger (22, 24, 26) extend from the primary section (20). The primary section (20) and each finger (22, 24, 26) have a length to width ratio between 3:1 and 1:1. The first finger (22) extends from one side of primary section (20) while the second and third fingers (24, 26) extend from its other side. The intersection (30, 32, 34) between each finger (22, 24, 26) and the primary section (20) is scored, thus allowing the fingers to be bent away from the primary plane. The cushioning benefit of the void fill material (10) is improved by the ability of the deformed fingers (22, 24, 26) to interlock with the fingers of the other void fill material pieces.
摘要:
This invention comprises apparatus and methods for folding and crimping shredded strips of sheet material into preselected lengths of interlocking, decorative material and/or bulk packaging material. The apparatus generally includes an attachment for a commercial paper shredding device which shreds sheet material therein. The apparatus comprises a movable barrier against which the shredded strips of sheet material are impelled upon being expelled from cutting blades of the shredding device. The movable barrier causes the strips to become controllably jammed within a confined area between the barrier and the cutting blades. Further insertion of additional strips into the confined area causes the strips to become compacted, folded, and crimped against a remaining dam of jammed sheet material located within the confined area. This causes the strips to fold and press against themselves, and form lengths of thin sheet material having an accordion-shaped configuration. Cutting blade components may be provided to further cut the strips into preselected lengths.
