[0001] PACKING PRODUCT, METHOD OF AND MACHINE FOR PRODUCING A PACKING PRODUCT

[0002] FIELD OF THE INVENTION

[0003] The present invention relates to packing products and, more particularly, to sustainable, re-usable, and efficient packing products for protecting packaged items.

[0004] BACKGROUND OF THE INVENTION

[0005] A significant number of items are shipped throughout the world every day. The growth of on-line purchasing has increased shipping tremendously. However, merchandise damaged during transit creates lost revenue for the vendor, the shipper, and frustration for the recipient. It is thus beneficial to the shipper, the merchant, and the recipient that the shipped items arrive undamaged. Items are shipped to a consumer via box, envelope, or other style of container. To try and ensure items do not get damaged during transit, dunnage or packing material is typically used to bundle the item(s) for shipping.

[0006] Heretofore, various types of low density packing materials have been used. Plastic “peanuts”, plastic balls, plastic bubble-wrap, plastic air-filled “pillows,” formfitting foam, straw and straw-like material have been or are being used as packing material. Most if not all of these packing materials have drawbacks. Plastic and similar materials are bad for the environment because they are generally not biodegradable and toxic to wildlife. The use of many, small pieces of low density packing material (e.g. Styrofoam balls, or peanuts), while efficient to surround and retain packed items, creates unpacking problems. Air-filled pillows do not effectively bundle items, allowing for gaps within the packaging. Such prior art packing material creates other problems as well.

[0007] In view of the above, it is evident that paper packing material would be preferred over other types of packing material since paper is biodegradable, recyclable, sustainable, and low density. However, lengths of crumpled or twisted paper, clumps of paper, or shredded paper is not practical for wrapping items, or for large-scale packaging. i

[0008] SUBSTITUTE SHEET ( RULE 26) Several patents and / or patent publications provide various ways of converting paper into a low density packing or cushioning product since paper converted into a low density packing or cushioning product is generally practical for packing. For example, U.S. Patent No. 6,626,813 discloses a cushioning conversion system and method for making a coil of cushioning product from a sheet of paper. Figure 6 of U.S. Patent No. 6,626,813 shows the produced coil of cushioning product (the ‘813 coil), the ‘813 coil having a width the size of the sheet of paper. The size of the ‘813 coil makes it impractical to form the coils into adequate packing material that can cushion around variously-shaped items without much manipulating of the ‘813 coil or cutting them. This adds an additional packing step. U.S. Patent Publication No. 2008 / 0153685 discloses a method of making a dunnage (packing) product from a continuous length of stock material having a cohesive on at least one surface. The dunnage product is a large coil of crumpled paper (the ‘685 coil) that uses its cohesiveness to keep its crumpled and coiled shape. Like the ‘813 coil, the ‘685 coil makes it impractical to form the coils into adequate packing material that can cushion around variously-shaped items without much manipulating of the ‘685 coil - adding an additional packing step. Moreover, the ‘813 and ‘685 coils are not able to form a generally amalgamated mass and / or a cohesive mass around an item or items for packing, creating only a loose assemblage of paper that can shift and move during transit. Without limitation, such prior art packing products are either too large, not easily formable around items of various sizes and shapes, and / or do not easily conform in shape to the interior of the items’ packaging.

[0009] In view of the above, it would therefore be desirable to have a paper-based packing product that alleviates the shortcomings of the prior art. It would be further desirable to have a paper-based packing product formed to provide adequate volume filler as a package / packaging without being a solid mass. It would be still further desirable to have a paper-based packing product formed to provide structural integrity with a lesser amount of material than a solid mass. It would be moreover desirable that the paper-based packing product clump or bunch together to create a packing mass about an item or items for packing.

[0010] 2

[0011] SUBSTITUTE SHEET ( RULE 26) SUMMARY OF THE INVENTION

[0012] A paper-based packing product, use, machine and method of manufacture is provided that affords protection of packed / packaged items.

[0013] The packing product is fashioned as a double curl, either a “B” or modified “B” (collectively, “B”), from a dimension controlled strip of paper. The strip of paper may be cohesive paper having a cohesive side and a non-cohesive side, a coated paper, or the like. The “B” is formed by a first curl wound or spiraled about a first end of the dimensioned controlled strip of paper, and a second curl wound or spiraled about a second end of the dimensioned controlled strip of paper. A small portion of the dimension controlled strip of paper connects the first and second curls. The first and second curls are wound or spiraled in opposite directions. If cohesive paper is used, the first and second curls are formed such that the cohesive side is / faces radially outward (outside) and the non-cohesive side is / faces radially inward (inside).

[0014] A plurality of “B”s provide a generally unified mass or clump around an item or items within (packed) in a receptacle (for example, but not limited to, and interchangeably herewith, a package, container, box, envelope, case, carton, basket, chest, drawer, packet, canister, can, or the like). In the case of the use of cohesive paper to form the “B”s, a plurality of cohesive “B”s provide a unified cohesive mass or clump around an item or items in a receptacle due to the cohesive “B”s loosely adhering to one another. The cohesive “B”s of the unified cohesive clump may also loosely adhere to the item or items, as well as the interior of the receptacle. A mass or clump may be compressed to reduce its volume and / or provide tighter packing. Mass or clump reduction may also be used to create or provide blocking or bracing of items within a receptacle. “B”s are moldable and fit the form of the item(s) being packed / packaged.

[0015] A method of packing an item or items using the present invention includes placing a plurality of the present “B”s in a receptacle (e.g. a packing container) along with the item or items. The “B”s may be cohesive “B”s or not (collectively “B”s unless indicated specifically as being cohesive or non-cohesive). The method may include providing a plurality of “B”s dimensioned and sized according to the item or items being packed, size of the receptacle, weight of the item or items being packed, or other parameter / consideration. Smaller and / or lighter items may use smaller “B”s while larger and / or heavier items may use larger “B”s, or vice versa. A mix of

[0016] 3

[0017] SUBSTITUTE SHEET ( RULE 26) different sized “B”s may be used. Other considerations, characteristics, and / or factors may determine dimensions or influence specifics of the “B”s. “B”s may be used for large, medium, or small items / receptacles, as well as light, medium, or heavy items / receptacles.

[0018] In one form, a “B" is formed from a roll or other source of paper (cohesive, non-cohesive, or a cohesive / non-cohesive blend, coated or the like) that is dimensioned controlled into a strip of paper having a width that is preferably, but not necessarily, one quarter inch (1 / 4”) to three quarters inch (3 / 4”), with one half inch (1 / 2”) being most preferable, and preferably, but not necessarily, two inches (2”) to twelve inches (12”) long. Other sizes are contemplated and may depend on factors and / or characteristics of the item or items being packed. The paper preferably, but not necessarily, has a weight from the teens to the fifties. The width or vertical side of a “B” provides blocking / stack strength for the packaged item(s), while the radial size or diameter of the first and second curls of the “B” provides cushioning as well as other benefits for the packaged item. When a plurality of “B”s are clumped together in random directions, a protectant mass is formed around an item or items by interaction of the shape of the curls of each “B” and, when cohesive paper forms the “B”s, “B”s naturally additionally adhere to one or another due to the cohesive side of each “B” faces outward. A mass of “B”s can assume any size and shape, especially around a packaged item, such as in a corrugated box. The mass also forming well inside the corrugated box. The “B”s surrounding the item or items stabilize as well as protect the item(s). Such packing also keeps the item(s) free from abrasion.

[0019] “B”s can be used to pack single or multiple items, light or heavy items, and within any receptacle, closed or open. “B”s may also be used in conjunction with an item or items that are wrapped in various materials such as, but not limited to, bubble wrap, tissue paper, butcher’s paper, newspaper, cohesive paper, construction paper, coated paper, cotton paper, and plant paper. Other types of wrapping such as, but not limited to, foam may be used in place of paper wrapping.

[0020] The “B” producing machine may be sized according to application need. For instance, a small desktop “B” producing machine may be used for packing small boxes, while a larger, free-standing “B” producing machine may be used for packing larger boxes. “B” producing machines may be fashioned for low volume “B” production or high volume “B” production.

[0021] 4

[0022] SUBSTITUTE SHEET ( RULE 26) A method of and machine for producing the present “B”s includes providing a roll of paper (i.e. a roll of a continuous sheet of paper), forming a first curl of a first diameter at the leading end of the roll of paper, cutting the roll of paper into a strip of paper having the first curl to provide the strip of paper with a trailing end distal the first curl, then forming a second curl of a second diameter at the trailing end of the strip of paper. If cohesive paper (e.g. paper with a cohesive on one face or side thereof) is used, the first and second curls are formed with the cohesive side facing radially outward.

[0023] In one exemplary form, a machine / method for producing the present “B”s uses a roll of paper to continuously create “B”s, preferably, but not necessarily, automatically, with pre-set dimension control of the produced “B”s. The present “B” producing machine is preferably, but not necessarily, processor controlled (e.g. computer) that at least provides control of the various components of the machine. The processor may also allow custom or on-the-fly creation of “B”s by dimension control including, but not limited to, the spiral length (amount) of each curl, the width of the strip of paper and each curl, the tightness of each curl (spiral), the length of connection between the first and second curls, and the like.

[0024] In the exemplary form of the machine / method for producing the present “B”s, the sheet paper is fed through a first slot of a first slotted spindle or rod then a second slot of a second slotted spindle or rod, rotating the second slotted spindle in a first rotational direction to wind the leading end of the roll of sheet paper into a first curl, cutting the roll of sheet paper at a location before the second slotted spindle to create a strip of paper with a trailing end distal the first curl, rotating the first slotted spindle in a second rotational direction that is opposite the first rotational direction to wind the trailing end of the strip of sheet paper into a second curl, and ejecting the produced “B” from the first and second slotted spindles / machine. Variations are contemplated. Other steps not specifically mentioned in this paragraph may intervene per the present principles and specification. The roll of sheet paper may be further dimensionally controlled by cutting the roll of sheet paper into one or more widths. Other dimensions may be changed.

[0025] A method of and machine for packing or cushioning one or more items within a packing container or receptacle includes providing a machine to produce a plurality of the present “B”s, then placing them around or about the one or more items, with or without the item(s) first being wrapped. The plurality of “B”s are preferably, but not

[0026] 5

[0027] SUBSTITUTE SHEET ( RULE 26) necessarily, dimensioned and sized according to the item or items being packed and / or receptacle particulars. Smaller items may use smaller “B”s while large items may use larger “B”s, or vice versa. A mix of various sized “B”s may be used. The present machines for producing the “B”s are adjustable to provide different lengths of “B”s, width, etc. for different packing needs.

[0028] Different papers may be used for the “B”s. The paper may be have a color, pattern, be different weights, have texturing or the like.

[0029] The present packing product is advantageous by providing efficient packing and / or cushioning of an item or items in a receptacle without necessarily filling the entire cavity of the receptacle. For instance, the present packing product does not need to fill the interior corners of a receptacle as it clumps around the item(s) in the receptacle. This cuts down on the amount of necessary packing product.

[0030] Further, the present packing product is lightweight. Moreover, the volume of the present packing product is not solid. It encompasses air between its curls.

[0031] The present “B”s provide a simple solution for multiple packing / packaging needs such as general void fill, protective void fill, general cushioning, light duty cushioning, heavy duty cushioning, blocking and bracing, decoratively, and containment. The present “B”s are also sustainable, reusable and / or recyclable by the consumer and in the supply chain, reusable by the same business, and end user reusable.

[0032] The present “B”s are easy and simple to use, provide for faster packing / packaging (which is a reduction in labor), allows the use of less material to pack / package items over conventional / prior art packing product. Use of the present “B”s can replace plastic and foam packing, result in reduction of packed / packaged item damage, and provide a positive customer experience.

[0033] Items as delicate or fragile as glass ornaments of any shape up to items of any practical weight and shape can be packed using the present “B”s, particularly when the “B”s have been custom produced regarding their curl size (number of.

[0059] SUBSTITUTE SHEET ( RULE 26) DETAILED DESCRIPTION OF THE INVENTION

[0060] In Fig. 1 there is shown a strip of cohesive paper 400, from the various types of paper that can be used for / in the present invention (see Summary of the Invention), to form a packing material in the form of a “B” (see, e.g., Fig. 2) or a modified “B” (see e.g., Fig. 2A) in accordance with the present principles. While cohesive paper is preferred, non-cohesive paper, coated paper, non-coated paper, a paper blend, or others may be used. The strip of cohesive paper 400 has a selectable width, a selectable length, a cohesive side 401 , a non-cohesive side 402, a first end 407, and a second end 408, the nomenclature first and second being arbitrary. The first end 407 may be considered a leading end, while the second end 408 may be considered a trailing end. The width of the strip of cohesive paper 400 is determined by the particular cutter 426 used in the packing product production machine 413 (see Figs. 5-7), set automatically or electronically. The dimensions of the cutter 426 fix the width of the strip of cohesive paper 400. Different cutters are used to change the width of the strip of cohesive paper 400. For instance, one cutter 426 of the packing material production machine 413 may cut the sheet 420 of the roll of cohesive paper 415 into multiple strips of cohesive paper having the same width, while another cutter may cut the sheet 420 of the roll of cohesive paper 415 into multiple strips of cohesive paper 400 each having a different width. A cutter 426 may not be used such that the width of the sheet 420 of the roll of cohesive paper 415 is the width of the strip of cohesive paper 400. A cutter 426 may allow on-the-fly variations in a width or widths of paper strips as controlled by the machine with / without human intervention. Variations are contemplated. The length of the strip of cohesive paper 400 is determined by the principles of the present invention as described below.

[0061] Figs. 3 and 4 depict a “B” 404 formed or produced by the exemplary packing product production machine 413. Machines of other designs may be used to create the packing material (“B”s) shown and described herein with the same or other methods of production. Fig. 3 provides a side view of the “B” 404 while Fig. 14 provides a perspective view of the “B” 404. The “B” 404 is formed by the strip of cohesive paper 400 such that the cohesive side 401 , preferably, but not necessarily,

[0062] 9

[0063] SUBSTITUTE SHEET ( RULE 26) faces radially outward, while the non-cohesive side 402 is preferably, but not necessarily, facing radially inward. If non-cohesive paper is used, the outward and inward faces (401 , 402) are both non-cohesive. The “B” 404 has a first curl, spiral, coil, twist, whorl or the like 406 formed at the first end 407 (arbitrarily, a leading end) of the strip of cohesive paper 400, and a second curl, spiral, coil, twist, whorl or the like 405 formed at the second end 408 (arbitrarily, a trailing end) of the strip of cohesive paper 400, the nomenclature first and second being arbitrary, with a connecting portion 409. The first curl 406 is wound in a first direction, while the second curl 405 is wound in a second direction opposite that of the first direction. Thus, one direction is clockwise while the other direction is counterclockwise. The first curl 406 has a first diameter while the second curl 405 has a second diameter, the first and second diameters may be the same or different as required, necessary, or desired. The tightness of the winding of the curl effects the diameter, as well as the length of paper used to produce the curl. Preferably, but not necessarily, the amount or length of spiral of each curl is sufficient to provide a spiral that will hold its shape after forming. Fig. 4 shows a mass 50 of “B”s 404 in a receptacle about and / or around the item 60 for, without limitation, product / item packing, cushioning, blocking, bracing, and / or void fill.

[0064] Fig. 2A provides a variation of the present packing product generally designated 404a having the same or similar components / characteristics / features to the packing product 404 of Fig. 2. As such, those components / characteristics / features that are the same have the same callout number, while those components / characteristics / features that are similar include the designation “a”. The packing product 404a may be formed with or without cohesive paper like “B” 404. The strip of paper 400 has a leading (first) end 407 and a trailing (second) end 408, the nomenclature first and second being arbitrary here and throughout, unless indicated to the contrary, and the assignment of leading and trailing being arbitrary here and with respect to the “B” 404. A first curl 406a of a first rotational direction and of a first diameter is provided at the f irst / leading end 407 of the strip of paper 400, while a second curl 405a of the first rotational direction and of a second diameter is provided at the second / trailing end 408. The first and second diameters may be the same. Since the rotational direction of the first and second curls 406a, 408a are the same, a modified “B” (packing product) 404a is created. io

[0065] SUBSTITUTE SHEET ( RULE 26) Referring to Figs. 5-7, there is shown the exemplary packing product production / forming machine 413. The packing product production machine 413 has a frame 414 having a base or bottom 418 supported by a plurality (here, four) of feet, pads or the like 419a, 419b, 419c, and 419d preferably, but not necessarily, at or proximate to the four comers of the base 418. More or less feet may be used. The packing product production machine 413 may also be assembled onto other types of mounting, as well as its components. It should also be appreciated that the components of the packing product production machine 413 and / or the manner of effecting production of “B”s may be different than that shown. The frame 414 also has an upturned portion 429 at a longitudinal side of the base 418 that supports a mounting plate 434.

[0066] The packing product production machine 413 is configured to hold a roll of cohesive (non-cohesive, coated, or otherwise) paper 415 for making the present packing material. The roll of paper 415 is held on a rotatable shaft 416 and rotationally supported by a first retention spindle 417 on a first side of the roll of paper 415, and a second retention spindle 441 on a second side of the roll of paper 415, the nomenclature first and second being arbitrary. The first and second retention spindles 417, 441 hold the roll of paper 415 onto the shaft 415 such that the roll of paper 415 can rotate with the shaft 416. The roll of paper 415 has a continuous sheet of paper 420 that is fed into the various components / mechanisms of the packing material production machine 413 that will cut and dimension the sheet of paper 420 into a strip 400, form one or more “B”s from the strip 400, and eject the one or more formed “B”s from the packing product forming machine 413, as described in more detail below.

[0067] The sheet of paper 420 is fed into a packing product forming portion or section 448. The sheet of paper 420 extends under a guide roller 422, under a rotating cutting roller 425, then over the cutter 426. As explained above, the cutter 426 dimensions the sheet of paper 420 into strips 400 of paper of widths according to the cutter 426. The cutting roller 425 is rotated by a cutting roller motor 427 that is supported on a frame portion 428 that is attached to a brace 423 that extends from the upturned portion 429. The cutting roller motor 427 is coupled to the cutting roller 425 for rotating the cutting roller 425 and feeding the sheet of paper 420 over the cutter 420 in order to cut the sheet of paper 420 into the strips of paper 400. The n SUBSTITUTE SHEET ( RULE 26) leading end 407 of the width-dimensioned strip(s) of paper 400 is then fed into and through a first curling rod or spindle 450, then further fed into and through a second curling rod or spindle 451 , the nomenclature first and second being arbitrary. The first curling rod 450 is coupled to a first curling rod motor 431 that is supported on a first frame portion 431 that extends from the mounting plate 434 for rotating the first curling rod 450, while the second curling rod 451 is coupled to a second curling rod motor 433 that is supported on a second frame portion 432 that extends from the mounting plate 434 for rotating the second curling rod 450, the nomenclature first and second being arbitrary. The first curling rod motor 431 provides rotational positioning of the first curling rod 450. Additionally, the first curling rod motor 431 is controllable to rotate the first curling rod 450 a given number of revolutions in order to curl the trailing end 408 of the width-dimensioned strip(s) of paper 400 as described herein. The given number of revolutions may be controlled to provide the second curl 405 of the “B” 404 with the given number of spirals as desired for a particular packing application or otherwise, and / or a particular diameter. The diameter may depend on the tightness of the spiral and the length of the second curl 405. The second curling rod motor 433 provides rotational positioning of the second curling rod 451 . Additionally, the second curling rod motor 433 is controllable to rotate the second curling rod 451 a given number of revolutions in order to curl the leading end 407 of the width-dimensioned strip(s) of paper 400 as described herein. The given number of revolutions may be controlled to provide the first curl 406 of the “B” 404 with the given number of spirals as desired for a particular packing application or otherwise and / or a particular diameter. The diameter may depend on the tightness of the spiral and the length of the first curl 406. The given number of spirals of the first curl 406 and the given number of spirals of the second curl 405 may be the same or different, again depending on the particular packing application or otherwise. As represented in Fig. 16, the first curling rod motor 431 (M2) and the second curling rod motor 433 (M3) are in communication with a processor 460 of the packing product forming machine 413. Likewise, the cutting roller motor 427 is controlled through communication with and via the processor 460.

[0068] As shown in Fig. 8, the first curling rod 450 has a first longitudinal slot 454 that is open at one end and closed at an opposite end, while the second curling rod 451 has a second longitudinal slot 455 that is open at one end and closed at an opposite

[0069] 12

[0070] SUBSTITUTE SHEET ( RULE 26) end, the nomenclature first and second being arbitrary. The leading end of the sheet of width-dimensioned sheet of paper is fed into the first longitudinal slot 454 of the first curling rod 450, then through the second longitudinal slot 455 of the second curling rod 451 . The first and second curling rods 450, 451 are positioned by their respective motors 431 , 433 via the processor 460 such that the longitudinal slots are aligned to allow the sheet of width-dimensioned sheet of paper to be fed through the longitudinal slots.

[0071] The packing product production machine 413 further has a sheet cutting motor 442 that is in communication with the processor 460 and labeled M5 in Fig. 16. The processor 460 controls the sheet cutting motor 442. The sheet cutting motor 442 is mounted on a support 443 and is configured to operate a sheet cutter 452 that cuts the sheet of paper 420 into the strip of paper 400 at the appropriate time. As described herein, the packing product production machine 413 further has an ejection motor 435 that is mounted to a plate 434 situated on the upturned portion 429 and which is in communication the processor 460 and labeled M4 in Fig. 16. The processor controls the ejection motor 435. The ejection motor 435 controls an ejection rod 437 that is connected to a sliding ejection assembly 436. The sliding ejection assembly 436 is movably attached to an underside of a rail 439 of a support plate 438 that extends transverse from the mounting plate 434. As the ejection motor 435 rotates the ejection rod 437, the sliding ejection assembly 436 is caused to move along the rail 439 away from the mounting plate 434. The sliding ejection assembly 436 includes an ejection plate 457 that moves with the ejection assembly 436. The ejection plate 457 extends essentially parallel to the mounting plate 434 and is configured to push or eject formed “B”s from the first and second curling rods 450, 451.

[0072] As best seen in Fig. 5, the packing product production machine 413 has a bar 440 that retains a first pivoting retention arm 444, and a second pivoting retention arm 446, the nomenclature first and second being arbitrary, here and below. As seen in Figs. 11-13, for example, the first pivoting retention arm 444 has a first conical projection 445 at a bottom of the first pivoting retention arm 444 that extends transverse to the first pivoting retention arm 444. The first conical projection 445 is configured to hold an end of the first curling rod 450 during formation of “B”s. Again as seen in Figs. 11-13, for example, the second pivoting retention arm 446 has a

[0073] 13

[0074] SUBSTITUTE SHEET ( RULE 26) second conical projection 447 at a bottom of the second pivoting retention arm 446 that extends transverse to the second pivoting retention arm 446. The second conical projection 447 is configured to hold an end of the second curling rod 451 during formation of “B”s. The first curling rod 450 along with the first pivoting retention arm 446 is configured to move along the bar 440 as explained below during formation of “B”s.

[0075] As depicted in Fig. 16, the packing product production machine 413 has a processor 460 for controlling operation of the various components thereof. The processor 460 may include memory for storing programming, as well as other components to provide the functions and / or functionality of the packing material production machine 413 necessary for operation thereof. The processor 460 may be any type of processor. The processor 460 is in communication with the cutting roller motor 427 (M1 ), the first curling rod motor 431 (M2), the second curling rod motor 433 (M3), the ejection motor 435 (M4), and the cutting motor 442 (M5). While not shown, the packing material production machine 413 may include an interface that allows a user to select various parameters for production of a “B”. For instance, a user may select a length of the sheet of paper 404 which determines, at least in part, the number of turns or spirals of the first curl 406 and of the second curl 405. The user may also select the number of turns or spirals, tightness, and the like of the first curl 406, and of the second curl 405. The number turns or spirals may be different. Other functions and / or parameters may be modified and / or selected via a user interface III 462.

[0076] The cutter 426 of the packing product production machine 413 may be replaceable in order to create “B”s of various widths. For example, one cutter may provide for a given number of “B”s of the same width. Another cutter may provide for a given number of “B”s of different widths. Rather than switching out cutters, the cutter 426 may allow for automatic change of its cutting blades to set a width or widths of formed “B”s. The interface would thus allow for the user to select the cutting width(s).

[0077] Figs. 9-14 depict formation of one or more “B”s via the packing product production machine 413 particularly the action of the first pivoting retention arm 444, the second pivoting retention arm 446, and the sliding ejection assembly 436. In Fig.

[0078] 14

[0079] SUBSTITUTE SHEET ( RULE 26) 9, the first curl 406 of a “B” 404 has been formed around the second curling rod 451 with the second pivoting retention arm 446 and its conical projection 447 holding the end of the second curling rod 451 . The second curl 405 of the “B” 404 has been formed around the first curling rod 450 with the first pivoting retention arm 444 and its conical projection 445 holding the end of the first curling rod 450. In Fig. 10, the sheet of paper 420 has been cut into the strip of paper 400 with the “B” 404 being formed. The first curling rod 450 and associated first pivoting retention arm 444 has been translated toward the second curling rod 451 and its associated second pivoting retention arm 446, with the second curl 405 wound more tightly. In Fig. 11 , the sliding ejection assembly 436 begins to slide outwardly along the rail 439 of the support bar 438 such that the ejection plate 457 begins to push the formed “B” 404 off the first and second curling rods 451 , 450. The first and second pivoting retention arms 444, 446 are caused to pivot outwardly on the screw bar 440 via rotation of the screw bar 440. In Fig. 12, as the screw bar 440 is further rotated to pivot the first and second pivoting retention arms 444, 446 fully out and upward, the ejection plate 456 is caused to further slide push the formed “B” 404 from the first and second curling rods 451 , 450. In Fig. 13, the fully formed “B” 404 has been fully ejected from the first and second curling rods 451 , 450 and from the packing product production machine 413. In Fig. 14, the screw bar 440 has been rotated reverse to the previous rotation that pivoted the first and second pivoting retention arms 444, 446 to pivot the first pivoting retention arm 444 and its conical projection 446 back to holding the first curling rod 450, and the second pivoting retention arm 446 and its associated conical projection 447 back to holding the second curling rod 451. The packing product production machine 413.

[0080] Figs. 15A-F depicts a representation of the creation of multiple “B”s 404a, 404b and 404c being formed by the present packing material production machine 413. While multiple “B”s are shown being formed, the same principles and procedure applies to the formation of a single “B” 404. Fig. 15A depicts the sheet of cohesive paper 420 having been fed through the first longitudinal slot 454 of the first curling rod 450, and the second longitudinal slot 455 of the second curling rod 451 . The sheet of cohesive paper 420 having been previously cut by the cutter 426 into three widths. In Fig. 15B, the leading end of the width-cut sheet of cohesive paper 420 has been wound about the second curling rod 451 by rotation of the second curling rod

[0081] 15

[0082] SUBSTITUTE SHEET ( RULE 26) 451 to create the first curls 406a, 406b, 406c. In Fig. 15C, the sheet of cohesive paper has been cut by the sheet cutter 452 into a strip of cohesive paper 400. In Fig. 15D, the width-dimensioned strip of cohesive paper 400 has been wound about the first curling rod 450 by rotation of the first curling rod 450. In Fig. 15E, the first curling rod 450 has moved towards the second curling rod 451 and has been further rotated in order to tighten up the formed “B”. In Fig. 15F, the three formed “B”s 404a, 404b, 404c are being ejected from the first and second curling rods 450, 451 by the sliding ejection bar 457.

[0083] It should be appreciated that other manners of producing packing product, “B”s, or modified “B”s, in accordance with the present principles may be used, and are contemplated.
