ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to the protection of materials stored on an industrial reel and, more particularly, to a corrugated wrap that is used to wrap the circumference of an industrial reel thereby providing protection to the materials stored thereon.
BACKGROUND OF THE INVENTION
Traditionally, wooden spools or industrial reels that are used to transport, store, and dispense various materials, e.g., fiber optics, other types of transmission cables, wires, etc., have had their contents protected through use of wood lagging strips, as shown in the prior art of FIG.
1
.
Referring to
FIG. 1
, the traditional, prior art manner of preparing an industrial reel
10
for shipping through the use of wood lagging
12
is shown. Industrial reel
10
is generally fabricated from wood and includes a central spool
14
and a pair of end plates
16
. Various types of wire and/or cable
18
are wrapped about the central spool
14
and maintained thereon by virtue of end plates
16
allowing industrial reel
10
to operate as a shipment, storage and dispensement container all in one. To prepare industrial reel
10
for shipment, wood lags (lagging strips)
12
are placed one-by-one around the circumference of industrial reel
10
, requiring significant preparation time. Each wood lag
12
is secured at each end by a nail
19
to one of end plates
16
. The nail is directed into the width
20
of each of end plates
16
rather than the interior face
22
or exterior face
23
of end plates
16
. As such, a nail directed at an angle presents the possibility of extending through the interior face
22
of end plate
16
, resulting in an unreliable wood lag and the possibility of damaging the contents of industrial reel
10
.
Each of the lagging strips
12
has been cut to the width of the industrial reel and secured to end plates through the use of nails and a nail gun. The wood lagging
12
presents gaps between individual lagging strips through which foreign material may reach the industrial reel contents. The securing and subsequent removal of the lagging strips
12
from the industrial reel
10
adds significant time, and resultant costs, to the industrial reel shipping process. The use of nails and a powered nail gun provides the possibility of injury to the individual preparing the shipment and, as well, the possibility of injury to the spool contents through virtue of a misdirected, long-shanked nail. Additionally, the wood lagging
12
itself adds significant cost to the shipping due to the weight the lagging adds to the industrial reel and its contents. Further, the disposal and/or re-use of the wood lagging
12
is not easily facilitated and also presents a significant recycling concern. Similar problems are presented by plywood and Masonite® lagging when used in place of the wood lagging
12
.
In an effort to address at least some of the problems described above, one manufacturer has produced an alternative to wood lagging
12
. Specifically, the alternative is a triple-layered material, i.e., an inner layer of polypropylene foam cushioning, a middle layer of recycled polypropylene, and an outer layer of spunbonded polypropylene. The inner layer is placed in direct contact with contents of the industrial reel and is wrapped directly about the contents rather than about the circumference of the reel end plates, as shown in the prior art of FIG.
2
. The material is secured against the contents of the industrial reel through use of metal banding strips, leaving the end plates exposed.
Referring to
FIG. 2
, the prior art alternative to the configuration of
FIG. 1
is shown. In the prior art embodiment of
FIG. 2
, a triple-layered material
24
, i.e., an inner layer of polypropylene foam cushioning, a middle layer of recycled polypropylene, and an outer layer of spunbonded polypropylene, is wrapped about the contents of industrial reel
10
and is positioned within the diameter of end plates
16
. Material
24
is held in position, i.e., in direct contact with the contents of industrial reel
10
, through use of one or more metal banding strips
26
. As a result of this direct contact, possible damage to the contents of industrial reel
10
is increased according to the pressure applied by metal banding strips
26
upon the contents. Note that because the contents of the industrial reel is most often spooled in a manner wherein the exterior of the contents is visible as a coursed configuration, i.e., the contents is in a side-to-side/top-to-bottom layer configuration as opposed to a layer-beneath-layer configuration as in adhesive tape, many portions of the contents are exposed for potential damage from the elements or reel-to-reel contact.
The alternative described above with reference to
FIG. 2
does significantly reduce the time needed to wrap and unwrap the industrial reel, it does reduce the overall weight of the industrial reel, and it does eliminate the need for nails and the possible injury they may cause. However, it introduces new problems that were not present with wood lagging. Because the material
24
of the alternative approach is in direct contact with the contents of the industrial reel
10
, there is the possibility that the pattern of the material
24
will be imprinted on the contents of the industrial reel
10
. Further, because this alternative approach wraps the contents of the industrial reel
10
rather than the circumference of the end plates of the industrial reel
10
, there is a possibility that the exposed end plate
16
of an industrial reel
10
will roll into the contents of another industrial reel
10
, thereby damaging its contents.
As such, there is a need in the art for a product that addresses the problems presented by wood, plywood, and Masonite® lagging as well as the problems presented by the above-described alternative approach.
SUMMARY OF THE INVENTION
The needs described above are in large measure met by the industrial corrugated reel wrap of the present invention. The industrial reel wrap is designed for wrapping an industrial reel having a central spool and a pair of end plates connected thereto. The industrial reel contains spooled contents that are generally wound so that a plurality of courses exists between the first and second end plates. The industrial reel wrap includes a central portion that is spannable across a distance between the end plates of the industrial reel. The industrial reel wrap additionally includes first and second side portions that are coupled to the central portion. The first and second side portions each include a number of tabs along the length of the industrial reel wrap. The tabs are securable to the exterior surface of each the end plates.
In one embodiment of the invention the industrial reel wrap is preferably provided with sufficient length so that it may continuously surround the exterior circumference of the industrial reel, spanning the distance between end plates, and so that the last tab secured to the industrial reel overlaps the first tab secured to the industrial reel to ensure a complete enclosure thereof. The tabs may be place in a side-by-side or gapped arrangement.
In another embodiment of the invention, the central portion of the industrial reel wrap is unitary with the first and second side portions of the industrial reel wrap, with the side portions being separated from the central portion by a formed double crease. The double crease is preferably used when the industrial reel wrap is of a corrugated material and the flutes of corrugation are oriented opposite to the length of the reel wrap, i.e., the flutes extend from end plate to end plate rather than about the circumference of the industrial reel.
In still another embodiment of the invention, at least the central portion is provided with one or more scores enabling the industrial reel wrap itself to be folded to a more compact shape for shipment purposes. Bi-fold or tri-fold configurations are two options for a folding scheme of the industrial reel wrap. In the instance of the industrial reel wrap being made
