[0001] The present invention relates to an assembly of stacked rolls or slabs of compressible
insulation material having an axial direction.
[0003] In these prior documents all the rolls or slabs of an assembly have either a vertical
axis direction or a horizontal axis direction.
[0004] The object of the present invention is to improve the loadability of the vehicles
provided for transporting said assemblies, particularly the trucks.
[0005] In order to solve this problem it is provided according to the invention an assembly
of stacked rolls or slabs of compressible insulation material having an axial direction
wherein the axial direction of one portion of said rolls or slabs is horizontal and
the axial direction of another portion of said rolls or slabs is vertical.
[0006] Advantageously each roll or slab is wrapped in a compressed state within a wrapping
film. Several wrapped rolls or slabs are preferably fastened side by side so as to
form modular elements wherein rolls or slabs have parallel axial directions, one portion
of said modular elements having in the assembly rolls or slabs with a horizontal axial
direction and another portion of said modular elements having in the assembly rolls
or slabs with a vertical axial direction. Preferably said several wrapped rolls or
slabs are fastened side by side, at a compressed state, by means of a packaging film
in order to form said modular elements.
[0007] According to an advantageous embodiment of the invention, several fastened modular
elements are arranged side by side so as to form groups of stacked modular elements
wherein rolls or slabs have parallel axial directions, at least one first group of
modular elements having in the assembly rolls or slabs with a horizontal axial direction
and at least one second group of modular elements having in the assembly rolls or
slabs with a vertical axial direction. Preferably said several fastened modular elements
are bound side by side, at a compressed state, by means of an enveloping film in order
to form said groups.
[0008] According to a preferred embodiment of the invention, said at least one first group
of modular elements and said at least one second group of modular elements are stacked
and tied to each other. Further the assembly may comprise a pallet on which the stacked
groups of modular elements are supported.
[0009] Advantageously, said stacked groups of modular elements are tied to each other, optionally
also with a pallet on which said stacked groups are supported, by means of a covering
bag.
[0010] According to an improved embodiment of the invention, the assembly comprises a lower
group of modular elements wherein the rolls or slabs have a vertical direction and
a higher group of modular elements wherein the rolls or slabs have a horizontal axial
direction. Preferably, each modular element comprises four rolls or slabs, the lower
group of modular elements comprises three modular elements and the higher group of
modular elements comprises four modular elements.
[0011] According to the invention, the compressible insulation material is preferably made
of glass fibres or mineral fibres.
[0012] Other details of the invention will result from the following description of a non-limitative
method for manufacturing an assembly according to the invention.
[0013] Fig. 1 shows schematically the steps followed for producing groups of stacked modular
elements intended to form an assembly according to the invention.
[0014] Fig. 2 shows an embodiment of assembly according to the invention obtained with the
groups of stacked modular elements produced on Fig. 1.
[0015] The illustrated method for manufacturing an assembly according to Fig. 2 is only
given as example. Other methods of manufacturing are obviously possible, for example
according to the teaching of the above mentioned prior documents.
[0016] Rolls 1 are made while winding a strip of compressible insulation material, for example
of glass fibre 2. Each roll 1 has an axial direction 4, here horizontal, and is compressed
within a wrapping film 3. The rolls have a diameter after compression of approximately
400-440 mm.
[0017] Thereafter the rolls 1 are fastened side by side with their axial horizontal direction
4 in a parallel arrangement by means of a packaging film 5. The rolls are compressed
perpendicularly to their axial directions 4 and form a modular element 6. The illustrated
modular element 6 comprises four rolls and has a length of 1300 mm and a width of
1160 mm.
[0018] Thereafter several modular elements 6 are stacked in two different groups 7 and 7'
wherein the rolls have parallel axial directions 4. The group 7 comprises three stacked
modular elements 6 and the group 7' four stacked modular elements 6.
[0019] These groups are again compressed according to a vertical direction and the modular
elements are bound side by side by means of an enveloping film in the form of a sleeve
8 and respectively 8'. The group 7 comprises three modular elements 6 and has a length
of 1350 mm, a width of 1160 mm and a height of 1200 mm. The group 7' comprises four
modular elements 6 and has a length of 1160 mm, a width of 1350 mm and a height of
1600 mm.
[0020] As illustrated on Fig. 2 the group 7 of stacked modular elements is rotated so as
the rolls which had a horizontal axial direction 4 receive a vertical axial direction
10. This rotated group 7 of modular elements has now a length of 1350 mm, a width
of 1200 mm and a height of 1160 mm. The rotated group 7 is then deposited on a pallet
9 having a length of 1290-1300 mm, a width of 1100-1130 mm and a height of 120-150
mm.
[0021] Thereafter the group 7' is stacked as such on the rotated group 7 while maintaining
the axial horizontal direction 4 of the rolls.
[0022] The arrangement of the group 7 with rolls having a vertical direction at the bottom
is preferable for improving the stability of the whole assembly on the wood pallet.
[0023] A covering bag may envelop the complete assembly optionally with the pallet.
[0024] It is obvious that the present invention is not limited to the illustrated and disclosed
embodiment and that several modifications may be envisaged within the scope of the
appended claims.
