SKID WRAP ROLLER
FIELD OF THE INVENTION
The present invention is relative to an invention which facilitates the
process of wrapping
skids in such a manner so as to secure their contents without causing
potential injury or harm to
the laborer.
BACKGROUND OF THE INVENTION
The packing industry is renowned for the back injuries and muscle strains that
often
afflict its laborers and packers. Improvements geared toward the ergonomics of
motion are often
overlooked where manual laborers are concerned. The current invention is
related to the field of
skid wrapping which is integral to t:he freight or packing and shipping
industries.
None of the relevant art, consisting of plastic wrap devices for wrapping
"skids", have
- 1 -

CA 02331247 2003-09-30
resolved the need for the operator to wrap skids from au awkward, bent over
position, that
~~cncrally puts strain on the spinal alignment and other muscles. furthermore,
smaller loads,
which arc too low to manipulate, also pose safety risks for the designated
wrappers; although this
type of load is generally placed on a forklift or electric lift to increase
accessibility, the skid
wrappers must often pass their arms and sometimes head beneath the skid in
order to completely
w°rap the goods.
U.S. Patent 4,102,513 issued to Twyman Guard on September 14, 1997 describes a
hand-held
apparatus which is used to wrap plastic stretch film around an object. Unlike
the present
invention, Guard's device has a short handle which still requires the laborer
to enter into
awkward and possibly dangerous situations in order to surround the object with
this fillll
material.
U.S. Patent 4,535,951 issued to Paul K. Riemenschneider, III on August 20,
1985 describes an
object useful in wrapping objects with a stretch film as well. This device,
however, involves a
mechanism in which a film roll with a tubular rigid core is clamped in between
a pair of opposed
core holders. A tension control assembly between the core and the core holders
is responsible for
adjustment of tension in the wrap during the wrapping process. Unlike the
present invention,
Riemenschrleider's device does not provide an easier method to wrap the object
which is
beneficial to the health and safety of the laborer. Due to the design of the
present invention, a
user may wrap well above and below regular reach eliminating undue tension
from bending aIld
standing on toes to reach low and high objects respectively.

SUMMARY OF THE INVENTION
The present invention is a device that is safer and more convenient for the
operator to use
than conventional wrapping methods. More specifically, the present invention
is a skid wrap
roller device which enables the operator to wrap skids from a safe position
minimizing the risk of
strain or other injury to life and limb. The present invention includes a
pole, with a stop on one
side, inserted into the hollow center of a spool of plastic wrap. The present
invention provides
the user greater control of the wrapping process while operating the device
from a standing
position.
The general structure of the present invention is a 60" wooden or hollow metal
pole ('/2"
dia.) with a 6" diameter plastic base and rubber stopper at one end. A
standard-sized plastic wrap
spool can be slid onto the pole from the other (unstoppered) end. The extended
pole functions in
like manner to a broom handle, enabling the operator to grasp the tool and
manipulate the
direction of the wrap from the top end (analogous to the broom handle), while
the plastic wrap
unrolls from the spool at the bottom end (where the broom head would be),
ultimately reaching
the desired goal of completely encasing the skid.
The wrap circumvents all elements which are placed upon the skid in an
organized and
uncompromising fashion to the laborer's well-being. The skid wrapper will be
at less risk for
potential back and neck pain as well as spinal misalignment.

BRIEF DESCRIPTION OF THE DRAWINGS
Figure 1 is a side view of the present invention.
Figure 2 is an exploded view of the brake assay.
DETAILED DESCRIP'CION OF THE PREFERRED EMBODIMENT
The present invention has a long wooden or metal pole (10), as shown Figure 1,
which is
approximately 60" long; a foam grip (70) is disposed at the end of the pole (
10). The long length
of the pole (10) allows the laborer to hold the device and extend a spool (80)
of wrap over an
area to be covered without the laborer bending down and twisting the laborer's
body in an
awkward position. The length of the: present invention eliminates squatting or
climbing to
properly wrap beds of items, and eliminates conventional ladder use in most
wrapping due to
height, because the spool (80) is disposed far along pole (10).
The pole ( 10) is inserted into spool (80) of wrapping material. Spool (80) is
hollow. The
diameter of 1 inch in the pole (10) provides for versatile use regarding
different size spools (80)
of wrapping material. Sleeve (68) is mounted atop pole (10) and has holes (50)
along the
- 4 -

diameter to act as attachments for a conventional cotter pin (not shown). The
holes (50) are
positioned along sleeve (68) for a 20~", 18", 15", or I 2" spool (80) of wrap,
and corresponding
holes (not shown) are similarly positioned along pole (10). It is contemplated
that variously
positioned holes (50) can be positioned along sleeve (68), and corresponding
holes (not shown)
can be similarly positioned along pole (10) depending on the length of a
particular spool (80)
chosen to be employed with the present invention. 'fhe hollow pole (10) serves
as an axis about
which the spool of wrap (80) can rotate. The smooth surface of the pole ( 10)
allows for
accelerated turning of the spool, and easier, expedited completion of the
wrapping.
A stopper (40), preferably m;~de of rubber, is continuous with a first end of
the pole (10).
The use of rubber for the stopper (4C1) allows easy turning access if the
first end is placed on
warehouse floors, loading docks or truck trailer beds while wrapping. The
stopper (40) also
protects low ceilings from marring as would happen with an unprotected end.
The stopper (40)
also acts as a safety measure to word;ers around the user if the present
invention is extended in a
somewhat horizontal manner from the objects being wrapped (not shown). Risk
for injury is
minimized by use of the stopper (40) if collision with other laborers should
occur.
Tension from a circular plate; (30) on the bottom side of the spool (80) and
circular plug
(20) on the top side of the spool (80) of wrap allow for secure and taut
wrapping of the objects
being wrapped (not shown). The circular plate (30) acts as a seat for an end
of the spool (80) of
wrap. The circular plug (20) also acia as a friction point to assist in the
unraveling of the spool
(80) of wrap. The plug (20) and plate (30) secure the spool (80) of wrap on
the pole (10). The
- 5 -

Hammontown, NJ 08037
circular plug (20) is easily removed for spool (80) replenishment. 'The plate
(30) and plug (20)
are preferably fabricated of heavy plastic that is durable and easy to clean
if necessary. In the
preferred embodiment of the presenl: invention, there are no bolts or screws
necessary for
attachment of plug (20) or plate (30). Plug (20) and plate (30) are separated
from spool (80) via
plug ring (22) and plate ring (32), respectively, which function like
conventional washers.
Between plate (30) and stopper (40) are threads (34) which are part of pole
(10). Threads
(34) serve as a mounting point for tensioner (33), which is threaded on
threads (34). Depending
on the amount of resistance desired ;as the laborer turns spool (80), the
tensioner (33) can be
turned on threads (34) to apply pressure to plate (30) and cause spool (80) to
turn more slowly, or
tensioner (33) can be turned on threads (34) to remove pressure fram plate
(30) and cause spool
(80) to turn more quickly.
Also included in the present invention is a brake assay (58) shown in Figure 2
as an
exploded view. The brake assay (58) works much like a bicycle brake, in that
it has an arm (60)
that can be depressed to stop the flow of the spool (80) of wrap around an
object (not shown)
being wrapped. The laborer completes the final wrapping motion around the
object being
wrapped and depresses the arm (60) so that it frictionally engages spool (80)
to prevent spool
(80) from moving. 'the laborer can easily cut the spool (80) of wrap from the
object being
wrapped with a tearing motion. The assay (60) enables the laborer to be
efficient in the quantity
of the wrap on the spool (80). Arm (60) pivots within channel (65), the second
part of the assay
(58), so that arm (60) that can be depressed to stop the turning of the spool
(80). The third part
- 6 -

of the assay (60) is the sleeve (68) ~~hich fits around pole (10). The sleeve
(68) provides a
mounting surface for the channel (6_'i), and sleeve (68) rotates about pole
(10).
The present invention can be utilized to assist in wraps above and below the
laborers
normal grasp of reach. The long lenl;th of the pole ( 10) allows for easy
access to high beds of
objects, while still having versatility in objects low to the ground or on the
floor. The
elimination of kneeling and squatting to wrap objects will greatly reduce
discomfort and possible
injury in the wrapping process.
Primarily, the present invention is intended to be used in the wrapping of
items with a
hand held non-motorized device, as in a warehouse for shipping or storing. It
is to be understood
that the present invention is not limited to the sole embodiment described
above, but
encompasses any and all embodiments within the scope of the following claims.
