Definitions
- the invention herein pertains to improved bale wrapping materials exhibiting a number of beneficial properties to overcome prior deficiencies.
- Such properties include a separation interface overlay that allows for greater rigidity at the formed leading and trailing edges of such wraps.
- shear-reducing wrap material portions is described, as well as recoil reduction structures within the formed leading edge regions.
- roll core adhesive additions allow for greater resiliency to the base wrap material as it unwinds therefrom, reducing potential waste wrap products by permitting greater amounts of wrap materials in use.
- Other considerations include the ability, through proper configuration designs, to position a wrap separation label within a certain range of distances from the formed trailing edge, thereby providing greater reliability of wrap dispensing during use. Such benefits are thus supplied individually and in tandem for improved versatility and utility of such wrap materials.
- Such wrapping materials may be used in conjunction with any solid objects that are typically collected, transported, and/or stored in such a manner.
- Objects including agricultural crops, fabrics, paper products, plastic products, basically any solid object, are typically provided in some manner that requires, at some point in time, wrapping of individual or multiple articles.
- Such wrapping whether within a plastic or polymer film, a netting, a mesh, or any like segmented web of material, is applied in such a fashion to facilitate collection, storage, transport, basically any type of protective activity for such objects.
- shrink-wrap films over boxes containing electronic equipment, packaging covering meat, vegetables, and the like, in a supermarket, even, as more fully described below, agricultural crop bales, wrapping materials have long been utilized for such valuable reasons.
- agricultural crops are typically harvested and collected into bales to facilitate transport and ultimate introduction within a processing machine (for instance, cotton is baled for transport to a gin).
- a processing machine for instance, cotton is baled for transport to a gin.
- wrapping articles have been provided to accommodate such necessary activities, particularly to ensure such crops are kept together during transport, as well as to allow for proper measurement of the amount actually harvested and transported. In any event, such wrapping articles have become a mainstay within the agricultural industry.
- wraps as typically used today, however, exhibit a number of drawbacks that lead to undesirable issues.
- wrapping materials that include adhered-to portions that require totally separated lengths of polymer materials during manufacture.
- Such materials again, using cotton as one non-limiting example, have been 0 developed to comply with certain requirements associated with such harvesting machines.
- the baling machine must include a clutch/brake mechanism to separate the wrap portion from its roll, and to permit feed of the trailing edge and separation from the
- This step thus ultimately permits the wrapping materials to unwind properly around the bale and then separate from the roll itself and adhere the trailing edge (separated from the roll) to the rolled bale surface.
- This secures the wrapping material around the subject bale in other words, and allows access to a new leading wrapping material edge to initiate rolling around a new bale within the harvesting machine.
- These wrap structures in use today, require the use of a folding of the web of wrap material over an adhesive layer to accommodate the protection of the adhesive layer, the braking and pulling of wrapping material a certain distance for such trailing edge adherence, and provision of a leading edge of a new wrap portion.
- This structure though, as noted above, requires separate wrap portions from the outset held together solely by adhesives on the base roll.
- the adhesive edges further may exhibit undesirable results during actual utilization in that preliminary contact between an adhesive edge with a portion of the baled structures, or even potential adhesion to the baling machine itself, may result in problematic jamming of the machine (or other problems).
- This structure thus may have nibs (if it is associated with a scored roll, for instance) that may be drawn into the baler machinery, or, otherwise, may simply be drawn as an entire leading edge therein.
- leading edge nibs may exhibit weaker adhesive capability upon application to a bale, or, vice-versa, the trailing edge may not exhibit suitable adhesive properties to remain in appropriate contact with the wound wrap already present on a subject bale. This could lead to undesirable unwrapping from around such a bale, among other things.
- the leading edge portion may engage with the rubber dispenser rollers of the harvesting machine, leading to, as noted, undesirable results.
- baling wraps of today Another notable problem with the standard baling wraps of today is the potential for slippage or expansion when placed around a bale. Any distortion due to uneven application or weakened regions around the bale itself could lead to the overall shape of the bale being compromised and further introduction within a specifically shaped transport and/or placement within a processor thereafter may be complicated or even prohibited, not to mention failure of the wrap to actually cover the subject crops from the elements during presence in a field while awaiting transport. In essence, such prior wrapping materials are prone to uneven stresses around a target bale.
- labels have been generated and applied to specific locations on a trailing edge.
- Such labels including, for instance, bar codes, QR codes, and the like, activate the clutch/brake once proper reading and notifying is provided to the harvester to allow for a set amount of time to stop the wrap cycle and allow for wrapping of the subject bale.
- These labels are typically applied at a set distance from the trailing edge for proper wrap separation (of folded wrapping materials, for instance) and sequential contact to adhere to the wrap material already in place on the round bale.
- the placement of such a label at a distance that activates the clutch/brake at an
- An advantage of the present invention is the drastic reduction of the propensity of such a wrapping material to exhibit recoil and/or undesired feed within a baling machine upon separation of a trailing edge from a leading edge. Another advantage is the ability to provide greater uniformity of such a finished wrap in terms of bale coverage with significantly reduced capability of bale size distortion during application and afterwards during storage and transport. Yet another advantage of the present invention is the reduction in waste material usage without losing back tensioning during utilization thereof such that substantially similar force is applied to the wrap when nearing its total unwound state from the base core. Still another advantage is the ability to apply a control label at multiple locations at the trailing edge of such wrap material.
- the present invention encompasses a roll of continuous wrapping material provided around a cylindrical core including a plurality of successive wrapping segments with a first wrapping segment, a series of middle wrapping segments, and a last wrapping segment attached to said cylindrical core, said wrapping segments being connected to each successive segment through periodic separable connections, wherein each of said wrapping segments has a leading section, a trailing section, and a body section therebetween, wherein said wrapping segment leading section extends from a leading edge to said body section, wherein said trailing section leads from said body section to a trailing edge, wherein said body section exhibits a width that is wider than the width of said leading section at its leading edge, wherein said configuration of said trailing edge is complementary to said configuration of said leading edge, wherein said leading edge of each wrapping segment is T/US2015/022330 adjoined to said trailing edge of a different wrapping segment through said periodic separable connections other than the leading edge of said first wrapping segment and the trailing edge of said last wrapping segment, and wherein each of said adjoined leading and trailing
- roll of wrapping segments as described above, wherein said overlay is optional, and wherein said body section includes rigidifying additions present therein.
- the wrapping material roll as described above including an indicator included within any location within said trailing section thereof to create a signal to control activation of the rolling device itself, with said overlay and said rigidifying additions being optional components.
- this wrapping material roll as described above, and including any or all of the overlay and rigidifying additions noted above, wherein said last wrapping segment is attached directly to said cylindrical core.
- the method of wrapping at least one solid object (such as, without any limitation intended, an agricultural bale, like cotton) within a wrap application device (such as, again, without any limitation intended, a harvesting device) with at least one wrapping segment of the inventive wrapping material rolls described above is also included.
- Such materials are typically provided as continuous webs of mesh, film, fabric, composite, and the like, with separable connections between adjoining wrapping segments (such as, without limitation, scoring, dotting, perforations, slits, etc.) introduced during manufacture.
- any surface additions including edge overlays, resiliency/rigidifying structures (longitudinal, crisscross, wave, circle patterns, etc.) are introduced during material manufacture as well.
- Such overlays would include scoring, dotting, slitting, perforations, and the like, as described in greater detail below, subsequent to introduction to the web surface.
- the very end of a selected web distance may be cut into a selected end shape of any geometry and provided with adhesive to attach to a core, as well.
- the terminal edge of the subject wrap includes double-sided adhesive to releasably attach to the core and, upon removal from such a core, the other side can then adhere to the outer surface of the subject wrapped bale, as well.
- a core is typically a cardboard or plastic cylinder of a certain diameter in order to allow unwinding of the wrap material at desired rates and distances.
- the web material may be etched, dyed, or otherwise applied with a label during manufacture at selected locations at the trailing edge of each wrap segment to wrap around a subject bale (or like harvested crop article).
- continuous roll or “continuous web” used herein is intended to mean a single piece of wrap material that has been provided with separable connectors integrated therein to allow for separation of segments within such a single piece of material.
- separable connectors or like descriptions are intended to mean, as noted above, integrated structures within a single material piece that facilitate separation of segments through application of a pulling force on a leading segment and an opposing (not necessarily equal) force on the trailing segment.
- Such connectors may thus include, without limitation, scoring, dotting, slits, perforations, and the like.
- Such connectors are unique to such wrap materials, particularly as they would include an overlay that overlaps with a trailing edge and an adjacent (until separation) leading edge of connected wrap material segments.
- Such an overlay may be applied on the top side or the bottom side (or both) of such a wrap material in such a manner, as well, in order to accord, as described herein, resiliency to each of such trailing and leading edges after separation.
- the increased bulk provided to such edges prevents undesirable recoil and/or loose "flapping" or elongation of the edges upon separation, thus preventing and/or drastically reducing the propensity for such loose edges to enter or otherwise entangle with the rolled bale or harvesting machine components
- a material such as, without limitation, a one-sided adhesive "tape" (with the adhesive side applied on the top or bottom side of the web, or possibly both sides simultaneously), a polymer strip attached to such single or both sides, or any other like material for such a purpose (including staggered strips, dots, and the like, that extend from the base wrap over any elongations created from separate of the connectors), accords such a beneficial result.
- overlay structures may be of natural or synthetic constituents (or blends thereof, for that matter) and may be adhered, bonded, welded (such as sonically welded), or otherwise connected to the subject wrap material.
- the overlay will take the same shape and accord such a cover that has, included therein, the necessary scoring, dotting, slits, perforations, etc., as desired for such wrap segment separation purposes.
- the scoring, dotting, slits, perforations, etc. are thus preferably introduced linearly in relation to the 2015/022330 desired edge shape (pointed structure, for instance) with any degree of coverage of the edge over the base material (preferably, though not necessarily, however, roughly half of the overlay covering the leading edge and roughly half then covering the trailing edge could be utilized).
- Such an overlay may be of any typical structure that is capable of adhering or otherwise attaching to such a base web material, and also allows for scoring, dotting, slits, perforations, etc., there through itself as well as the base web material simultaneously during manufacture.
- Such overlay materials thus may be selected from the group of paper, polymeric, or fibrous backed
- adhesive tapes or material suitable for thermal attachment to the wrap web are adhesive tapes or material suitable for thermal attachment to the wrap web.
- the invention encompasses the utilization of extra material within selected regions of the base web material in order to accord resiliency to the overall structure thereof when wrapped around a subject bale.
- the overall wrap may distort as well, leaving the bale susceptible to uneven shaping or even uncovered portions. If the wrapped bale remains in a field for an indefinite time period prior to transport for processing, the lack of wrap coverage could be disastrous.
- the transport device cannot properly maneuver, lift, or otherwise move such a wrapped bale due to unevenness in overall shape, loss of product may result as the lack of transport capability would force drastic measures or even a decision to leave such an uneven roll in the field.
- Such a wrapping material could be invigorated to militate against such a potential deleterious result.
- the inclusion of an extra amount of material, either through an attached strip of resilient polymer or other like article, or even through thickened regions of polymeric material within the subject web, all within the body of a wrap segment, has been found to provide such beneficial properties.
- Such extra material may be present as longitudinally applied strips or thickened portions a certain distance from the longitudinal edges of a subject wrap material web (such as about 3 inches wide, about 2-4 inches from the longitudinal edges of the web, as examples).
- the extra material amounts may be provided as geometric strip shapes throughout the web body, particularly, in one potentially preferred configuration, as crisscross patterns within the web material itself.
- such a geometric strip (or thickened regions) within the material web accords resiliency within the overall wrap to retain a certain tension and thus shape around a rolled bale.
- This extra material amount thus allows for greater reliability to the user in that once applied, the even application of such a roll material will be retained until transport is undertaken and delivery made to a processing location.
- Such extra material may also be supplied with exposed adhesive components (whether in terms of strips, areas, and the like) present thereon at the surface.
- Such an adhesive matrix similar to such materials described herein, would be present on the wrap surface external to the subject bale in order to permit greater reliability of dimensional stability of the wrap itself once applied around the subject bale with multiple revolutions.
- the adhesive provides discrete portions of the wrap body surface that accord further contact and attachment of the multiple wrap layers surrounding the subject bale.
- the wrap exhibits a reduced propensity for both unwrapping after application, as well as less chance of slippage of the wrapping material itself to ultimately keep the bale intact.
- Such an adhesive exhibits a suitable level of bonding strength to apply to the wrap material around such a bale, but also at a sufficiently low level to permit the supplied wrap prior to bale application to unwind from within the harvesting device easily and without undesirable retention therein.
- the waste material inherently present within typical bale wraps in utilization today is a significant problem.
- Such waste material includes not only the core, but also an amount of wrap material that is roughly the same width as that of a typical wrap itself and typically from twelve to fifteen feet in length.
- wrap material When a roll is exhausted, the core and waste material will typically be disposed of at the field site itself. Unless the user then returns to pick up the waste materials, these are typically left in the crop field, contributing to litter in such a manner.
- it was found that such a wrap material may be supplied with zero waste, but with sufficient back tension to accommodate the necessary actions and operations of the wrap material when maneuvered by the harvesting machine during use.
- the adhesion of the wrap material to the core can be accomplished by products such as hook and loop or adhesives with good release properties.
- the end structure of the last wrap can actually be wound against itself around the core without the utilization of any adhering product and still unwind and properly expose the tab adhesive on the trailing edge for application to the wrap around the bale.
- Such non-adhered end structure may, however, include an adhesive matrix on the wrap surface that is not in contact with the core. Such a matrix imparts resilient strength around the core without requiring any adhesive attachment between the wrap and the core.
- the wrap material would be wound around the core with the last one or more material levels including discrete areas or strips (or the like) of adhesive applied to ensure adhesion between such wound levels of the wrap itself.
- This provides a certain bonding strength to prevent unwanted slippage of the wrap material from around the core while still exhibiting a suitable low level of adhesion such that unwrapping does not require inordinately high pulling forces from the harvesting device during utilization.
- Such alternative end structures for bale wrapping materials have been unexplored in the past.
- a stop action e.g., a clutch/brake mechanism or separation component
- the wrap includes a label with appropriate indicators present thereon for a reader embedded or otherwise associated with the harvester to scan and read for such a desired action to commence.
- the typical wraps in use today are limited to a very specific location for the placement of such labels in order to activate the clutch/brake at a specific time during wrapping.
- the present invention allows for placement of a label for such a purpose at a range of distances on the web material proximal to the trailing edge.
- label placement anywhere from 1/16* of an inch to 30 inches from the further point of the trailing edge may be employed as a potentially preferred embodiment for such a purpose.
- the actual placement may be any location within the subject wrap segment dependent upon a number of factors, including, without limitation, the separation mechanism, the clutch/brake mechanism, and/or the roll mechanism, as well as the actual objects to which such a material is being applied.
- the clutch/brake can appropriately operate to maximize efficiency in relation to needed tension for separation to occur, as well as to ensure that undesirable possible entanglements between the wrap material and the harvester machine are avoided.
- Such labels may thus be printed, applied (as a sticker, for instance), painted, etc., to the wrap material surface within the range of distances noted above.
- This versatility allows for control of the clutch operation of a harvester to achieve total wrap leading and trailing edge separation and avoid double wrapping, as well.
- the ability to reduce the propensity for such trailing edge portion damage during separation may be overcome through provision of easier-to-separate attachments within the pointed structure trailing edges of such wrap segments.
- such structures may be provided with fewer and greater spaced slits, perforations, etc., in these regions to facilitate such separation with lower amounts of force needed for such a purpose.
- separation is achieved in a more reliable manner for these specific trailing edge locations, leaving the pointed structures intact, with a far lower propensity for tear potential and thus entanglement (or other like problem) during operation. Such is described in greater detail below.

- Such wrapping materials are provided in an elongated, continuous sheet form in separable wrapping segments stored consecutively on a reel or a core.
- Such a wrapping material may be utilized for use in wrapping of solid objects, here, in particular, for the potentially preferred embodiments described herein, agricultural products, such as cotton, and may be composed of one or more of a variety of materials including, without limitation, polyolefin films, polyolefin nettings, mesh, and woven or fibrous materials,
- the width of such a wrapping material should be sufficient to cover the width of the subject bale or other item being wrapped including overlapping and sealing ends that are thick enough to withstand the handling and elements of nature if left in an agricultural field for a period of time surrounding a subject bale.
- the thickness of a potentially preferred agricultural wrapping material substrate is from about 40 to about 120 microns and the length of a wrapping segment is from about 15 to about 25 meters, depending upon the harvested material. It would be well understood by the ordinarily skilled artisan that such an inventive wrap is scalable to any desired size for different types of wrapped materials. For the baling process, sufficient wrapping material is contained on a supply reel or core to yield a field supply roll of sufficient wrapping segments for harvesting a multiplicity of round bales. The amount of wrapping material on the supply roll would be limited to the capacity of the harvesting machine in terms of the storage and technological capabilities of said harvesting machine. With that basic background provided, the invention may be better understood with the following descriptions and explanations, particularly as the inventive wrap and method of utilization thereof accords significant improvements over the state of the art now employed in the field.
- Figures 1-3 provide a view of a prior art bale wrap 3 rolled on a core 1.
- the wrap 3 has multiple segments 7, 9 each separated by a scored line 10 (such as by slits, perforations, and the like, as described above).
- the segments 7, 9 move likewise in direction Y.
- the core wrap segment 7 is stopped and the leading segment 9 is pulled away, causing separation between the two segments 7, 9 with a leading edge 14 on the core segment 7 and a trailing edge 12 on the leading segment 9.
- This loose leading edge 14, as shown in Fig. 3 may allow for the formation of elongate or fibrous pieces of wrap material which can become co-mingled with the substance being wrapped.
- the loose leading edge may also be twisted or undesirably allowed to flap thereafter, which may lead to capture within the harvester machinery (not illustrated).
- the wrap 103 is present, again, on a core 101, with multiple segments 107, 109 separated by a scored line 1 14.
- a trailing section segment 107 has a leading edge covered by an overlay 1 11 and a leading section segment 109 that has a trailing edge covered by an adjacent overlay 1 13.
- the entire overlay 112 is applied as a single structure scored
- the scored (perforated, etc.) line 1 14 thus actually provides a line of demarcation not only within the entire overlay 1 12 but also between the edges of the leading and trailing section segments 107, 109 that permits separation thereof. Also present is an underside adhesive layer 1 19 to allow for adherence to a bale wrap of the leading section segment 109.
- the trailing end 117 of the leading section segment 109 includes a re leasable substrate (such as a liner) 115 that protects the adhesive layer 119 during the unwinding phase and may also provide extra structure to the trailing end 117 upon separation from the trailing section segment 107.
- the leading section segment 109 follows in direction Y and the entire overlay 112 and leading and trailing edges covered thereby of the two segments 107, 109 are then separated, as shown in Figure 5.
- the entire overlay 1 12 may be applied to the opposite side of the subject wrap material instead, as an alternative; the adhesive and releasable substrate may also be alternatively applied to the opposing material side, too.
- the roll direction D may be in either configuration allowing for the wrap material to go under or over (here, under is shown) the roll.
- Figure 6 provides an aerial view of an individual wrap segment 200 having a leading section 204 and a trailing section 202.
- longitudinal strips 206 are integrated within or applied on the surface of the wrap segment 200 within the body thereof to accord greater dimensional stability during and after wrapping is completed. Such strips 206 are shown here as two parallel structures, although there may multiple structures, if desired, with staggered lengths within the body of the segment 200.
- Such strips 206 may also be provided with adhesives thereon or therein with a complementarily configured releasable substrate 207 placed there over that provides protection of the adhesive during an unwinding phase and, upon automatic removal of the releasable substrate during unwinding, adhesive access to impart further slippage reduction characteristics of the subject wrap material when present around a wrapped bale (such as in Figure 14).
- Figures 7 and 7A illustrate the utilization of rigidifying portions 322 at a location near separable connectors 310 (such as scoring, perforations, etc.) between section segments 307, 309 in order to reduce the propensity for undesirable movement of such an edge 310 after separation of the section segments 307, 309.
- Such a configuration is distinctly different from any placement of dampening strips, for instance, within the pointed area of the leading end of such a segment 307.
- the rigidifying portions 322 which may be applied as overlays or extra material within their specific regions, situated behind the pointed edge 310 thereof, accords a certain degree of control and resiliency without having to introduce such structures closer to the edge 310.
- the wrap 303 present on a core 301, may include the simpler scored line 310 between a trailing segment 307 and a leading segment 309 with reduced propensity for twisting or flapping thereof upon separation (as shown in Figure 7A) with the wrap 303 unwinding in direction D (as above, such a direction may be the opposite of that shown and over, rather than under, the wrap present on the core) and brake stop X (with the roll direction D, stopped as well as in Figure 7A) applied to allow for the leading section segment 309 to detach while the leading section segment 309 moves in direction Y, leaving a trailing edge 313 thereof and a leading edge 31 1 of the trailing section segment 307 that remains dimensionally stable for further operation.
- Figures 8, 8A, and 8B show a wrap material structure 353 with the separation between leading and trailing section segments 357, 359 accomplished through unwinding in direction D and movement of the materials in direction Y and including a sufficient stress differential accorded the wrap material 353 in relation to the retention of the trailing section segment 357 on the core 351 and the unwound leading section segment 359.
- the separable connectors 360 allow for lower stress differentials to permit such separation, ostensibly resulting in such separation once the leading section segment 359 is free from the wrap 353 around the core 351 in its entirety, thus facilitating such separation without any need for brake stopping (as for D and X in Figure 7A, for instance) of the harvesting device (not illustrated) during operation.
- the leading segment 359 moves in direction Y and continues as the connectors 360 begin separating (Figure 8A) leaving, in Figure 8B, a trailing edge 363 and a leading edge 361 in the segments 357, 359. Only when the leading segment 359 is clear of the roll 353, and the rigidifying portions 372 impart resiliency to the leading edge 361 of the trailing segment 357, the trailing segment 357 can be stopped (D and X) without associated flapping, twisting, or other like issues (Figure 8B).
- Figure 9 thus a variety of possible configurations of rigidifying portions 406 of a wrap segment 400.
- Such a specific configuration of such portions 406 is not intended to be required; this Figure simply shows non-limiting possible configurations of rigidifying portions 406 that may be utilized for such a purpose.
- the leading end 404 and trailing end 402 are separated by a central structure of strips 406 for such a purpose.
- the presence of such a structure 406 within the body of the segment 400 accords dimensional stability as provided by both the structures of Figures 6 and 7, above.
- Such structures 406 may also include strips or at least discrete applications thereon at their surface of exposed adhesives (not illustrated) analogous to the releasable substrate shown in Figure 6, for the purpose of protecting the adhesive during unwinding, for example.
- Such adhesives would impart greater strength to the multi-wound subject bale wrap, allowing for greater resistance to slippage of such wound material as well as drastically reduced potential for peel and shear thereof, as well.
- Figures 10 and 10A provide views of the novel utilization of a suitable adhesive at the end of an entire wrapping material roll 503 in order to allow for reliable attachment (in releasable fashion) to the subject core 501.
- the end wrap segment 503 includes juxtaposed regions 505 that emulate, to a certain degree, the trailing edges (313 of Figure 7A, for example) of potentially preferred wrap segments (as discussed above).
- this configuration is not presented as limiting to any degree, as any suitable geometric shape may be utilized in this manner.
- these ends 505 include adhesive release tabs 515 (Figure 10A) thereon that allow for attachment to adhesive areas 507 on the 22330 core 501, allowing, ultimately, the ability to utilize the entirety of the wrap material on a provided roll (e.g., preventing any need for waste material to be generated).
- the wrap 503 includes adhesive edges 51 1 opposite the adhesive release tabs 515.
- the wrap material 503 is separated from the core 501, and the adhesive edges 511 of the end portions 505 may thus be applied to a wrapped bale (such as in Figure 13) in secure fashion, just as any other prior segment trailing edge including a release substrate 508 that protects the adhesive 51 1 as described previously.
- the core 501 thus retains adhesive locations 507 thereon, as well.
- Figures 10B and IOC provide views of the novel utilization of a suitable adhesive at the end of an entire wrapping material roll 553 in order to allow for reliable attachment (in releasable fashion) to the subject core 551.
- the end wrap segment 553 includes juxtaposed regions 555 that emulate, to a certain degree, the trailing edges (313 of Figure 7A, for example) of potentially preferred wrap segments (as discussed above).
- this configuration is not presented as limiting to any degree, as any suitable geometric shape may be utilized in this manner.
- these ends 555 include adhesive materials 561 thereon and/or therein that allows for attachment to another area of the wrap 553 when wound around the core 551, thus being retained on the core 551 through tension.
- the wrap material 553 is unwound from the core 551 and upon release of the adhesive from the release tabs 568 on the wrap material 553, the last segment of the wrap material unwinds completely from the core 551, leaving no wrap material or adhesive thereon.
- Figure 10D provides a cross-sectional view of one potentially preferred embodiment of the core 570 and the last segment of the wrap material 573 as it is applied to the core 570.
- the core 570 turns in direction D while the wrap 573 moves toward and around the core 570 in direction Y.
- the exposed adhesive 580 adheres to the wrap material 573 at its contacted surface 584.
- the wrap 573 and core 570 then continue to wind until the entire wrap 573 is rolled thereon.
- Such adhesive composites including the adhesive 581, liner 578, and exposed adhesive 580 are provided throughout the wrap material in intervals relative to the trailing edges of each wrap segment.
- Figures 10D, 10E, 10F, and 10G show the last segments including these adhesive composites; it should be well understood that such components are present throughout the entirety of the wrap material, with, for instance, the adhesive composites and adhesives 581, liners 578, and exposed adhesives 580 configured in any desired shape and/or alignment thereon and/or therein (such as the pointed structures 115, 1 19 of Figure 5, as one example).
- Figures 10F and 10G thus show the resultant effect of such adhesive composites upon unwinding of the subject wrap material 573 from the core 570.
- Figure 1 1 provides further improvement as the utilization of an inventive wrap material as herein described.
- a label 605 is typically provided on wrap segments 601, 603 to facilitate activation of a clutch/brake mechanism (not illustrated) of a rolling device (not illustrated), such as, for instance, as one non-limiting example, a harvesting device that collects and wraps a bale.
- a rolling device not illustrated
- these labels are applied at a specific location on such segments in order to ensure proper reading by a sensor 620 to activate the brake stop (not illustrated) (or, for other rolling devices, stop or separating mechanisms, as needed), thereby allowing for separation of segments to occur.
- a wrap roll 600 includes a label 605 that may be introduced at any location within the trailing edge region 610 of a wrap segment 603.
- locations 607 thus allow for greater versatility as well as potentially greater versatility overall for the operation of the harvesting device to properly brake stop and allow for definitive separation of segments 601, 603, leaving a leading edge 61 1 for a trailing segment 601 in addition to the trailing edge 610 of a leading segment 603.
- This ability for label placement selection is starkly divergent from the prior art that typically utilizes a straight, perpendicular separation line between segments.
- Such a label 605 must be situated in one spot for activation purposes, basically, leaving the overall wrap susceptible to less control by the harvester device to operate appropriately.
- such a label 605 may be supplied in any location of the subject wrap for such control purposes, dependent upon the subject objects to be wrapped and machinery utilized therefore and therewith.
- the label 605 may be of any indicator that provides an effective means to signal when a specific location of a subject wrap segment reaches a certain place within the rolling device that subsequently activates the device as needed (separation, braking, etc.).
- such an indicator may be any type of structure, addition, structural change, etc., that can provide a differential change for such a signal purpose (read or detected by a suitable component on the rolling device, for instance, include a color, light, laser, etc., sensor, and the like).
- Indicators may thus be bar codes, QR codes, colors, opaque structures, transparent wrap areas, basically anything that accords such a beneficial signal result that is specific for the necessary location within the wrap material for such a purpose.
- Figure 12 thus provides an aerial view of the interface of two segments 701 , 703 of a wrap material 700 with limited connections 707, 709 therein that noticeably do not connect at the side edges of the wrap 700.
- Such a disposition of connections 707, 709 best ensure effective separation occurs of the two segments 701, 703.
- the leading edge 702 of the trailing segment 701 and the trailing edge 705 of the leading segment 703 thus are more easily separated when sufficient, low force is applied for such an action.
- a nib connector (or other like structure) may be provided intact and exhibiting sufficient strength for such a purpose may be supplied proximate to the leading and tailing edges 71 1, 713, thereof.
- Figure 13 shows a multi-wound bale 800 including agricultural product 810 (such as, as one non-limiting example, cotton) and the wrap material 820 as provided in Figure 5, above with the trailing edge 830 adhered to the wrap material 820.
- agricultural product 810 such as, as one non-limiting example, cotton
- wrap material 820 as provided in Figure 5, above with the trailing edge 830 adhered to the wrap material 820.
- the other wrap materials of the inventive Figures, above, would be wound in like fashion and to similar effect for the wrapping of any desired solid object or objects.
- edge overlays Such improvements as outlined and described in greater detail above accord a user for greater reliability in the field than standard wrapping materials now employed for such purposes. Whether there is provided edge overlays, rigidifying structures, fully removable and usable wrapping materials from a subject core, a multi-positioned label, and/or carefully constructed perforations, etc., at edge interfaces of separable segments, these improvements all impart beneficial results that have heretofore been unexplored and certainly been unattainable in this industry.
