Package and a method for manufacturing said package.
The present invention relates to a package for
a continuous flexible device which is wound up into a coil like
a cable, a line, a rope, a hawser, a wire, a hose or similar
within a protective enclosing casing which is suitable for
storage and transport.
A method for packaging for example cable in the
form of a coil in a package for feeding out from within, is
known from SE-B-469 228. However, the pulled out cable etc.
will present a spiral shaped persistent form like a spiral.
This is a considerable disadvantage and for avoiding this, it
would be necessary to rotate the package and thus to compensate
for said spiral shape.
SE-B-469,228 also presents a package which
protects during storing and handling for example cable. The
cable is spooled into a standing cylinder and is pulled out as
a coil and it will therefore turn itself one revolution for
each revolution of the cable which is pulled out from the
cylinder, i.e. the cable will turn itself which is exactly what
the present invention is aiming to solve, so that the cable
will be straight when it is pulled from the packing.
It is evident that there is a need for a device
which solves this problem.
GB-A-2,143,870 relates to a system for winding
where a wire is wound onto a drum from which the wire is later
wound off. A drum less coil is utilised from which the wire is
wound off from the outside by means of a means of assistance.
This also results in that the outfeed opening will be unlimited
and it would cover the entire gable of the package.
For this object a special rotating cable
outfeed device (45) which is described on page 2, lines 27-38,
must be utilised for feeding out the wire (12) from a wire drum
(15). Nothing is mentioned about packaging of the wire and thus

W097/453~3 ~CT/SE97/00777-
no axial outfeed through an outfeed opening at one side of the
package.
US-A- 1,431,352 relates to a package from which
it is possible to pull a short or a long piece of a conduit
through an opening without having to break the package. This
package discloses nothing related to any preshaping of the
conduit but is only a package from which it is possible to pull
out conduit or the like several times without damaging the
contents.
US-A- 3,135,380 relates to a package support
which enables a tilted positioning of the package. This is not
the essential for the present invention, even if it could be
seen as an advantage when the contents of the package starts to
come to an end and the weight of the package is small. By
tilting it backwards, it will be more difficult for it to
"drop" forward when pulling out wire, conduit or similar.
SE-A- 8404780-2 discloses equipment for moving
a wire coil to another coil with the object to exchange inner
and outer ends or to cut up a large coil into smaller coils.
With this equipment, the wire can not be drawn straight out
unless the wire is turned or twisted.
The main object of the present invention is
therefore in the first hand to solve said problem efficiently
with simple and well functioning means.
Said object is accomplished by means of a
package according to the present invention, which is
substantially characterized in that the flexible device is
wound up preshaped and received within a casing, which is
provided with a centrally located outfeed opening for said
wound up flexible preshaped device at the front side of said
casing, and that the centrally located outfeed opening is
formed by an aperture through the casing by what means the
,, _ ,

W097/45353 PCT/SE97/00777-
flexible device may be drawn out of the casing without rotation
of the spool-shaped wound up coil.
The invention also relates to a method for
manufacturing a package for a continuous flexible device which
is wound up into a coil like a cable,,a line, a rope, a hawser,
a wire, a hose or similar within a protective enclosing casing
which is suitable for storage and transport.
A further object is therefore to permit
manufacturing a suitable package.
Said further object is achieved by means of a
method in accordance with the present invention, which is
substantially characterized in winding up said mentioned
flexible device by preshaping it, that is by a relative
movement between a bobbin and a winding up device for said
flexible device, whereupon the to a spool-shape wound up
flexible preshaped device is moved to a casing allowing it to
be enclosed in it with an end extractable through a centrally
located outfeed opening at the front side of the casing, and
that the centrally located outfeed opening is formed by an
aperture through the casing by what means the flexible device
may be drawn out of the casing without rotation of the to a
spool-shape wound coil and without forming a spiral upon the
flexible device.
It should be clearly evident that the
continuous flexible device which is wound up into a coil is
wound up by preshaping and is then removed to a casing which
exhibits a centrally located outfeed opening at one front side
of the casing. In this way, the flexible device is arranged so
that it can be pulled out from the casing without the need for
any rotation of the spool shaped wound coil having to occur and
thus, without forming of any spiral upon the flexible device.
This a considerable advantage which now is enabled.

The main feature of the present invention is
thus that a flexible cable etc. is wound up preshaped to be
received inside a casing which is provided with an outfeed
opening at its front side.
BY that means no extra eaui~ment is needed at
the site of pullinq out the cable from the formed coil, since
the Pullina out is done without turninq or twistinq the cable
and which is straiqht due to its ~reshapinq durinc ~oadinc into
said packaqe.
According to the present invention, the cable
is pulled out directly from the inner end of the coil without
any extra appliances. This is possible due to the preshaping of
the cable at its loading and the special design of the package.
The pulling out of the cable is done without turning or
twisting the cable. This is instead straight due to its
preshaping during loading into the package.
The invention will now be described as a
preferred embodiment with reference to the accompanying
drawings, in which
Fig. 1 shows a package according to the present
invention in an outfeed position for a cable from an enclosing
casing seen obliquely from the front,
Fig. 2 shows the package seen from behind, also
in the outfeed position for the cable,
Fig. 3 shows an example of an outfeed opening
of the package, and
Fig. 4 is an explanatory sketch of a method for
winding the cable onto a bobbin for forming a spool shaped
coil.
The flexible device 2 is wound up preshaped
inside a package 1 according to the present invention, which is
designed for housing a cable, a line, a rope, a hawser, a
thread, a conduit or some other similar continuous flexible
-

W097/45353 PCT/SE97/00777-
device 2 which is wound up into a coil, which is enclosed
within a protective enclosing casing 3 which is suitable for
storage and transport of the flexible device 2. This implies
that said flexible device 2 is wound up by means of a special
wind up apparatus 4 onto a bobbin 5 a~d that the bobbin 5 and
said wind up apparatus 4 in doing so are rotated relative each
other in the desired direction of rotation 6 and 7 respectively
during the preshaping of the device.
Said wound up preshaped flexible device 2 is
freely received inside a rigid casing 3 which exhibits a
centrally located outfeed opening 8 in the form of a round hole
for said wound up flexible device 2, preferably at the front
side 9 of the casing.
The casing is preferably formed by means of a
cardboard box 3 which presents a square shape and which is
provided with a suitable handle means 10 at its top 11.
Further, the centrally located outfeed opening
8 of the casing 3, is formed by a hole which extends completely
through the casing 3 and its front side 9.
It is also possible to realise the casing by
means of a soft material, as for example a plastic material,
especially shrinking plastic, and which also may display a
centrally located outfeed opening according to the previous
described embodiment with a rigid casing.
Preferably, the outfeed opening 8 may be
arranged to be easily expandable gradually, in order to
facilitate outfeed of the flexible device 2 as it is drawn out
through the opening 8. Therefore, the casing 3 exhibits on its
front side 9 a number of ring-shaped segments 12, 12A ... that
may be torn away successively from the inside around said,
preferably with circular circumference designed, outfeed
opening 8. Preferably, said tear-away segments 12, 12A ... are
formed by crooked perforations 13 extending through one wall of

the casing and which preferably is provided with easily break
off straight perforations l~ running across said perforations
13, starting as seen from the outside circumference 15 of the
casing 3. Thus, the diameter of the outfeed opening 8 may be
increased when necessary, by tearing away segment after segment
12, 12A.... of the casing wall.
In order to enable erection of the package l, a
support 16 is arranged and which is located at the casing 3.
The erection support 16 may be formed by a fold out part 17
upon the back side 3A of the casing 3, and which is provided
with an inclined bottom edge 18 with relation to the bottom
side l9 of the casing 3 in order to enable tilting of the
package l for facilitating feeding out forward 20 of the
flexible device 2, which may be pulled out in the direction of
pull 2l.
After winding up the flexible device 2 to a
coil, by winding up the flexible device 2 onto an internal
bobbin 5 according to prior art, preferably having a
cylindrical shape, said formed spool-shaped wound coil is moved
to said cardboard shaped casing 3.
The free end 2A of the flexible device may be
pulled out through a centrally located outfeed opening 8 at
said casing 3 for problem free outfeed without forming a
spiral, which otherwise easily could be formed, which may be
studied at an electric cable which may be wound up into a coil.
I.e. that a straight cable now may be obtained when it is
pulled out, and without forming any loops that "snutter" (get
tangled) into each other.
The flexible device 2 is wound up by preferably
rotating said wind up apparatus 4 in the desired direction 6 of
winding, and by which the flexible device 2 is supplied to the
bobbin 5 and around it in accordance with prior art. Then the
flexible device 2 extends axially 23 with reference to said
CA 022~610 1998-11-18
W097/4~353 PCT/SE97/00777-
bobbin 5, before the flexible device 2 is fed for tangential 24
supply to the bobbin 5.
Before winding on, the flexible device 2 may be
received upon a large reel 25 which is supported by a reel
support 26 for easy outfeed to the fo~med winding up apparatus
4. After winding up the device 2 to a formed spool-shaped coil
27, this is enclosed in the designated casing 3 according to
the above, which is a rectangular casing and which is provided
with an opening 8 in one side 9 and an erecting support 16 at
the opposite side 3A.
The invention is not limited to the above
described and in the drawings shown embodiment, but may be
varied within the scope of the claims without departing from
the inventive concept.
