No. 10/517,172 filed May 1, 2007 as a National Stage entry of PCT/IB2004/003475 filed Oct. 22, 2004, the subject matter of each of the preceding applications, are hereby incorporated by reference in their entirety herein.
FIELD OF THE INVENTIONThe present invention relates to a variety of wrapping materials, and in particular, wrapping materials incorporating a fastener, which secures the tail end of the wrapping material to the fibers of an underlying portion of the wrapping material at the conclusion of a wrapping cycle.
BACKGROUND OF THE INVENTIONThe use of balers for baling agricultural crops into “round” bales (referring to a generally cylindrically shaped bale having a generally round cross-section) has become increasingly common in recent years, replacing the old system of baling square bales that were secured by different types of twine or metal wire. The first round-balers also used various types of twines to secure the bale, however, over the years different types of netting have been used. The use of netting, and in particular, knitted Raschel netting, has become more and more common. Raschel netting is a knitted netting that typically is made from polymeric material and includes a plurality of equally spaced longitudinal ribbons known as “franzes” and a plurality of intervening zigzag ribbons known as “schusses.” However, the netting used, including Raschel knitted netting, is primarily open, with the franzes and schusses only making up a small percentage of the surface area of the bale and does not protect the bales from rain.
Plastic film wrap, including “sticky film” wrap has been used to wrap whole bales or portions of bales, with the goal of protecting a bale from rain.
However, the use of impermeable plastic film wrap does not allow moisture already within a baled crop to escape there from, since it is bound by an impermeable plastic layer. Since the inherent moisture level in baled crops may be on the order of one or more dozen percent of weight of the crop (for example, in baled hay), this bound-in humidity easily promotes spoilage of the baled crop.
Moreover, when such plastic film has been used in existing netting systems, typically only a portion of the bale was covered, leaving part of the circumference unwrapped and exposed to rain and/or to moisture from the ground on which the bale is resting. If the entire bale was wrapped with plastic film, then internal moisture could not escape. Likewise, any excess moisture gained by the crop from exposure to weather also promoted spoilage of the baled crop. Since bales are often left in a field, exposed to weather for a year or more, cumulative rain and/or ground moisture penetration may be significant, as may be the resultant crop spoilage.
Another disadvantage of using plastic film as a bale wrap has been that the film does not, itself, grasp onto a bale or underlying film layer, and thus a “sticky” portion had to be incorporated to prevent unraveling of the bale. However, use of such sticky film, even if only a small amount, was difficult to feed into a baler. Reasons for this include that, in the process of loading the film and wrapping a bale, the sticky film stuck to elements of the machine as well, making use of these materials difficult. In order to solve the problem of sticky film sticking to a baling apparatus itself, significant alterations to the baling apparatus had to have been made, often proving not to be cost-effective. The use of VELCRO, or VELCRO-type fasteners for wrapping and closing containers are known, as shown by U.S. Pat. No. 5,732,531 to de Silva et al., EP 0 608 871 A2 to de Silva, and Published UK Patent Application GB 2 221 841 A to Pentith.

SUMMARY OF THE INVENTIONWith the foregoing in mind, the wrapping materials of the present invention provide a solution to the problems noted above in the prior art.
In accordance with an aspect of the present invention, a fastener, i.e., at least one fastener is attached to a woven or non-woven wrapping material. Upon wrapping an item, each fastener cooperates with fiber elements of an underlying or overlying segment of the wrapping material to engage, lock, hold, or otherwise fasten the wrapping material tightly around the circumference of the item being wrapped with the tail end of the wrapping material being secured to the corresponding overlying or underlying segment of the wrapping material.
Each fastener preferably includes, for example, a plurality of small “J”, mushroom, or finger shaped engaging elements, although other shapes may be used. Each of these engaging elements include an engaging element body having an engaging element base at one end and terminating at an engaging element free end for engaging, catching, grabbing, locking, holding, or otherwise fastening to the fiber elements of a corresponding underlying or overlying segment of the wrapping material. The engaging element body, from its base to its free end, extends, at angle relative to a fastener base, a length that is sufficient to allow the free end to engage, catch, grab, lock, hold, or otherwise fasten into fibers of the underlying or overlying segment of the wrapping material at the conclusion of a wrapping cycle.
Each fastener may be positioned anywhere along the length of the wrapping portion that allows each fastener to carry out its intended function. In some embodiments, for example, the fastener may be positioned near the tail end area of each wrapping portion of the wrapping material. In other embodiments the fastener may be positioned near the central region of each wrapping portion of the wrapping material. Still, other embodiments may include the fastener positioned near the leading end or other areas of each wrapping portion of the wrapping material.
Each fastener may also be positionally oriented on the wrapping material within an angular range of substantially parallel to the length direction of each wrapping portion to substantially transverse to the length direction of each wrapping portion. With these arrangements, a wide variety of continuous and/or discontinuous areas of connection between each fastener and their respective underlying or overlying segment of wrapping material may be realized that would allow fine tuning of the connection force and connection area to specific uses, items to be wrapped, and environmental conditions, just to name a few.
The wrapping material of the present invention may be fabricated, for example, from at least one continuous wrapping component, which may be in the form of either a continuous, single wrapping component or a continuous, composite wrapping component. The wrapping material of the present invention may also be fabricated from at least one of the aforementioned continuous wrapping components in combination with at least one discontinuous wrapping component, which is different from the continuous component. The wrapping material is preferably provided in roll form and comprises a plurality of end-to-end connected wrapping portions each having at least one fastener associated therewith. Each fastener may be formed, for example, as either a single fastener component or a plurality of co-acting, discontinuous fastener components. The at least one continuous wrapping component is preferably made from a woven or non-woven material and has a width substantially equal to the width of the item to be wrapped and a length sufficient for covering at least the circumference of the item to be wrapped. The at least one discontinuous wrapping component is preferably made from a breathable polymeric material having a width substantially equal to the width of the item being wrapped and a length for covering at least a part of the circumference of the item being wrapped. In embodiments where the wrapping material is fabricated from one of the aforementioned continuous wrapping components and without the discontinuous wrapping component, the continuous wrapping component may, preferably, be made from the same, or similar, breathable polymeric material as the at least one discontinuous wrapping component used in other embodiments.
The forgoing specific objects and advantages of the invention are illustrative of those that can be achieved by the present invention and are not intended to be exhaustive or limiting of the possible advantages that can be realized. Thus, these and other objects and advantages of this invention will be apartment from the description herein or can be learned from practicing the invention, both as embodied herein or as modified in view of any variation that may be apparent to those skilled in the art.
