Description
Insulating package
This invention relates to a package of compressed mineral wool insulation blowing
wool fibres, a method for manufacturing such a package and a method of filling a blowing
machine using such a package.
Glass blowing wool fibres are generally retained by a plastics envelope under
compression in a package having a mass of about 15.5 kg and dimensions of about 120cm x
55 cm x 25 cm. During opening of the package, due to release of the compression, the
blowing wool fibres tend to be released in all directions leading to spillage of the fibres. In
addition, the sides of the package tend to be curved rather than planar due to the compression
of the blowing wool and flexibility of the plastics packaging material; this makes it more
difficult to stack packages for efficient transportation, for example by truck. Furthermore, the
dimensions of the packages which are intended to allow manual handling are not suited to
efficient arrangement on standard pallets.
One aim of the present invention is to provide an improved form of packaged mineral
fibre blowing wool.
In accordance with one of its aspects, the present invention provides a package of
mineral wool insulation blowing wool fibres as disclosed herein. Additional aspects of the
invention are disclosed herein, including in the recited preferred and/or alternative
embodiments.
When the package is opened, notably by releasing its retainer(s), the expansion of the
blowing wool fibres along substantially a single expansion axis, notably a vertical axis,
provides a system in which the blowing wool does not overflow beyond the footprint of its
package. Consequently, the package may be opened, moved once opened and/or loaded once
opened into a feeder of a blowing machine without any significant spillage of the blowing
wool. This is particularly advantageous when the package of blowing wool is adapted to be
used in an automated feeder system, notably
a feeder system adapted to accept large or pallet sized packages of blowing wool. The
package of blowing wool may be used to fill a hopper of a blowing machine, notably using an
automated feeder system.
The expansion axis is preferably the vertical axis. This allows the upper surface of the
package to be opened without any significant overflowing of the blowing wool.
By “substantially a single expansion axis”, we mean that, in a (x,y,z) configuration,
where the major expansion of the mineral wool insulation blowing wool fibres is in the z axis
(i.e. the z axis is the expansion axis), although some expansions along the x axis and/or y axis
may also occur any expansion along the x and/or y axis is not significant and is notably no
more that 10% of the expansion along the z axis. For example, the expansion along the
expansion axis between a retained configuration (in which the package is held under
compression) and a released configuration (once the retainer(s) has been removed) may be:
≥ 20 cm, ≥ 30 cm , ≥ 35 cm, ≥ 50 cm, ≥ 75 cm, or ≥ 100 cm; and/or
≥ 20 %, ≥ 30%,≥ 35%, ≥ 50%, ≥ 75%, or ≥ 100% with respect to the package’s
dimension along the expansion axis in its retained configuration; and/or
≤200 cm, ≤150 cm, ≤80 cm, or ≤ 60 cm; and/or
≤ 200 %, ≤ 150 %, ≤ 120 %, ≤ 100 %, ≤ 80 %, or ≤ 60 % with respect to the package’s
dimension along the expansion axis in its retained configuration.
The term expansion refers to the change in dimension; where the expansion axis is
vertical the expansion along this axis is preferably measured at the central position of the
upper surface of the package, for example when the package is supported on a horizontal
surface or pallet.
Expansion along each axis other than the expansion axis may be:
≥ 0.5 mm, notably ≥ 1 mm; and/or
≥ 0.05 %, notably ≥ 0.1 % with respect to the package’s dimension along the
expansion axis in its retained configuration; and/or
≤ 30 mm, notably ≤ 20 mm, or ≤ 15 mm or ≤ 10 mm; and/or
≤ 5 %, notably ≤ 3% or ≤ 2 % with respect to the package’s dimension along the
expansion axis in its retained configuration.
The end surfaces and/or the side surfaces of the package in its retained and/or
released configuration may be substantially planar. This facilitates efficient transport of
retained packages and/or loading of released packages in to a feeder system. In this
context, substantially planar means that the maximum gap under a straight rule placed
against the surface is ≤ 30 mm, preferably ≤ 20 mm.
The retainer may comprise one or more securing strap(s), for example three, four,
five or more securing straps, notably of plastics or metal, arranged around the package.
Each securing strap may have a width which is ≥ 8mm, notably ≥ 12 mm and/or ≤ 25 mm.
Alternatively, wire securing straps may be used, notably each securing strap comprising a
wire having a diameter which is ≥ 0.5 mm and/or ≤ 4 mm. Preferably each securing straps
passes over the side surfaces and the upper and lower surfaces of the package leaving the
end surfaces free from securing straps. This facilitates placing and removal of the securing
straps.
The package may also comprise an enveloping film, notably comprising a plastics
material. The envelope may comprise at least two portions, preferably three portions, notably
an upper portion, a middle portion and a lower portion. In a preferred embodiment the upper
portion covers the upper surface of the package and an upper part of the four lateral
surfaces, the lower portion covers the lower surface and a lower part of the four lateral
surfaces and the middle portion covers the four lateral surfaces and overlaps the upper
portion and/or the lower portion. This facilitates free expansion of the mineral wool with little
or no constraint from the enveloping film and/or removal of the enveloping film.
The mineral wool insulating blowing wool fibres may comprise or consist of glass
fibres, rock fibres, slag wool fibres, virgin fibres, white wool fibres, binderless fibres, flocks,
recycled fibres (notably recycled fibres from cured, binder containing mineral wool) or
combinations thereof. Preferably, the blowing wool fibres are glass wool fibres. The fibres
may be loose fibres and/or flocks; preferably they do not comprise a binder, notably an
organic binder.
Where the fibres are glass wool fibres their composition may comprise:
SiO2 55-75 %wt; Na2O + K2O 10-20%wt; CaO 5-15 %wt; CaO + MgO 5-20 %wt; Al2O3 0.5
– 8 %wt; Fe2O3 (total iron) 0-5%wt, B2O3 0-10 wt%, notably 1-6 wt%.
Compression of the mineral wool insulation blowing wool fibres within the package
reduces the size of the package and facilitates transportation. The level of compression,
and thus the density of the retained package, is selected to optimise reduced volume whilst
avoiding damage to the fibres and providing suitable properties of the fibres upon release.
The package may be six-sided package, comprising an upper surface, a lower
surface and four lateral surfaces (including two side surfaces and two end surfaces) notably
a cube and/or substantially a rectangular parallelepiped. The dimensions of the package, in
its retained configuration may comprise:
a length which is ≥ 0.9m or ≥ 1m or ≥ 1.15m and/or ≤ 1.5m or ≤ 1.4m; and/or
a width which is ≥ 0.75m or ≥ 0.9m and/or ≤ 1.2m or ≤ 1m; and/or
a height which is ≥ 0.8m or ≥ 0.9m or ≥ 0.95m and/or ≤ 1.5m or ≤ 1.2m.
Such dimensions are particularly suitable for arranging the package on a pallet; these
dimensions also reduce the amount of packaging film used compared with known smaller
packages of blowing wool. Furthermore, such dimensions are also particularly suitable for
loading in to a blowing wool bale condition system for feeding a blowing machine. In one
preferred embodiment the width of the package is about 0.8m and its length is about 1.2m;
in another preferred embodiment the width is about 1m and the length is about 1.2 m.
The package comprising mineral wool insulating blowing wool fibres may, notably
when full or in its retained configuration, have a mass of at least 130 kg, at least 150 kg, at
least 160 kg, at least 170 kg or at least 180 kg; it may have a mass of no more than 250 kg
or no more than 200 kg.
Manufacture of the package may comprise compressing blowing wool fibres along a
single axis, notably a vertical axis, to produce a compressed bulk of blowing wool fibres. The
at least one retainer may be arranged around the package prior to release of pressure , for
example by passing one of more securing straps through openings in a pressure retaining
plate and around the package.
An embodiment of the invention will now be described, by way of example only, with
reference to the accompanying drawings of which:

Fig. 9 is a side view of the package of Fig 8; and
Fig. 10 is a top view on the package of Fig 8.
The compressed package of glass blowing wool of Fig. 1 is a six-sided package (1)
comprising an upper surface (10), a lower surface (11) and four lateral surfaces which are
two end surfaces (12’, 12’’) and two side surfaces (12’’’) (only one side surface is visible in
Fig 1). The package (1) in its retained configuration is substantially a rectangular
parallelepiped, having a length of about 1m, a width of about 0.8m and a height of about 1m.
The blowing wool fibers are loose, binderless glass wool fibers having an average diameter
in the range 3.5 µm to 6.5 µm preferably manufactured by an internal spinning process.
The package (1) has a density of about 150kg/m³ and a mass of about 145kg; it is
supported by a pallet (14).
The package (1) is enveloped by three portions of a plastics enveloping film (131,
132, 133). The upper portion (131) of the enveloping plastic film covers the upper surface
(10) and about 15cm of the upper part of the four lateral surfaces (12’, 12’’, 12’’’). The lower
portion (133) of the enveloping film covers the lower surface (11) and of about 15cm of the
lower part of the four lateral surfaces (12’, 12’’, 12’’’). The middle portion (132) of the
enveloping film covers the four lateral surfaces (12’, 12’’, 12’’’) and overlaps about 5cm of
the upper portion (131) and about 5cm of the lower portion (133) of the enveloping film.
The package (1) also comprises retainers in the form of five plastics securing straps
(13) arranged around the package (1) over the enveloping film and passing over the upper
surface (10), the lower surface (11) and the two side surfaces (12’’’). The securing straps
(13) tightly secure the package and maintain it under compression; they may produce some
deformation and/or non-planarity of the upper, lower and side surface (not shown). The end
surfaces (12’, 12’’) are free of retaining straps and are planar.
The securing straps may be cut using scissors in order to be removed from the
package. When thus released, the package expands uniquely along its vertical expansion
axis (z) from its retained configuration (shown in Fig 1) to its released configuration (shown
in Fig 2). In its released configuration the four lateral surfaces (12) are substantially planar.
Release of the retainers causes the height of the package to increase as the compression in
the packaged blowing wool is released but as the expansion is only along the vertical axis
(z) none of the loose blowing wool spills over beyond the package’s footprint.
The blowing wool package is manufactured by a baler (2) illustrated in Fig 3. A
desired mass of loose blowing wool (not shown) collected in a weighing hopper (31) is
discharged in to a rectangular section loading zone (32). A loading piston (33) pushes the
weighed blowing wool horizontally along the loading zone (32) in to a compression zone (34)
having the lower portion (133) of an enveloping film (not shown) pre-positioned at a base 35.
The upper portion (131) of the enveloping film (not shown) is positioned between an upper
surface of the blowing wool and a compression piston (36) which compresses the mineral
wool along a vertical axis. The compressed bulk of blowing wool fibres is then transferred,
whilst being maintained under compression, from the compression zone to a packaging and
strapping unit (37) at which the middle portion (132) of the enveloping plastic film is arranged
around the four lateral surfaces (12) and the retaining straps (13) are secured. When
removed from the packaging and strapping unit (37) and arranged on a pallet the retaining
straps maintain the package under compression.
The package (1) is a stable, self-standing machine loadable package particularly
suited for transport to and loading in to a blowing machine (4), as illustrated by Fig. 4. The
blowing machine may be used to introduce blowing wool in to cavities of pre-fabricated
building walls during their manufacture or in to cavities of metal building panels.
Once transported to the location of the blowing machine (4) the retainers (13) are
removed from the package (1) and the blowing wool fibres expand along the vertical axis but
without overflowing beyond the footprint of the package. The upper portion (131) and central
portion (132) of the enveloping plastics film is then removed in order to provide a package
loadable into a bale conditioning system (3) which comprises:
- an elevator (41) on which the package (1) on the pallet (14) is placed;
- a fibre unloader (42) at a upper portion of the bale conditioning system; and
- an outlet (43) leading to an inlet feeder (44) of a blowing machine (4).
The fibre unloader (42) comprises a belt (45) or alternatively a moving, rotating or
reciprocating bar which, during raising of the package on the elevator, causes claws (46) to
collect fibres from an upper surface of the package and deposit then in the outlet (43) from
where they are fed to the inlet of the feeder (44) of the blowing machine. The raising of the
package on the elevator and the displacement of the fibres from the upper surface of the
package to the inlet of the blowing machine may be continuous or sequential.
The lower portion (133) of the enveloping plastics film may be secured to the pallet,
for example by staples, to avoid any risk of it being detached and fed to the blowing
machine.
Fig. 5 also shows a package in a retained configuration, the curvature of the upper
and lower surfaces being exaggerated. Fig. 6 shows the package of Fig. 5 which has been
pivoted and laid on one of its lateral surfaces on a pallet so as to take advantage of the
planarity of the side surface for additional stability for transportation. Such a configuration
may also facilitate stacking a package or pallet on top for transport and/or storage. Fig. 7
shows the package of Fig .6 in a released configuration after having been pivoted back to its
initial position and after removal of the securing straps.
The package illustrated in Fig 8, Fig 9 and Fig 10 has a width w of 80 cm, a total
height ht of 120 cm, a side height hs of 100 cm and a length l of 120 cm. Four retaining
straps (91, 92, 93, 94) encircle the top, bottom, front and rear surfaces to retain the blowing
wool contained within the package. The first (91) and fourth (94) retaining straps are
positioned at a distance d of between 3 and 7 cm from their adjacent end faces. The
spacing s between each adjacent strap is substantially the same, for example about 380 cm.
The package is enveloped by three portions of a plastics enveloping film (not shown).
An upper portion of the enveloping plastic film covers an upper surface (80) and about 25cm
of the upper part of the four lateral surfaces (101, 102, 103, 104). A lower portion of the
enveloping film covers a lower surface (81) and of about 25cm of the lower part of the four
lateral surfaces (101, 102, 103, 104). A middle portion of the enveloping film covers the four
lateral surfaces (101, 102, 103, 104) and overlaps about 25cm of the upper portion and
about 25cm of the lower portion (133) of the enveloping film.
