Method for binding a bundle of loose leaves or the like and
binding element, end leaf or cover applied thereby.
The present invention concerns a method for binding a
bundle of loose leaves or the like.
In particular, the present invention concerns a method for
binding a bundle of loose leaves or the like in a cover with
a back.
A method for binding a bundle of loose leaves in a cover
with a back is already known, whereby the end leaves of this
bundle are provided on the respective outsides and are
provided with a layer of glue over their entire surface,
and whereby the leaves of this bundle are subsequently
joined together on one side edge by means of gluing or
stitching, after which this bundle of leaves is provided
with the glued or stitched edge in the back of the cover and
the . cover is subsequently folded up, so that the end
leaves are glued to the inside of the cover by the above-
mentioned layer of glue.
A disadvantage of such a known method is that, in order to
join, the bundle of loose leaves together by means of gluing
or stitching and to provide a layer of glue on the inside of
the cover, a manufacturing device is always required
which is usually relatively expensive, as a result of which
such a method is not interesting for sporadic and/or private
use.
WO 2007/039804 PCT/IB2006/002737
The present invention aims to remedy the above-
mentioned and other disadvantages.

{¦To the end,—the present invention concerns a method for
binding a bundle of loose leaves or the like in a cover
with a back, which method mainly comprises the following
steps:
binding a free edge of the above-mentioned bundle of
loose leaves;
- providing the bundle of leaves with its bound edge in
The free edge of the bundle of loose leaves can be
bound in many ways, for example by means of stapling,
stitching, cold gluing, punching with plastic or metal
rings or other binding techniques.
applying a | layer of glue |which| has |proforably| been provided
|boforehand|, either on the |cover or on the bundle of—loose
leaves,—particularly onf end leaves which are bound together
with the bundle of loose leaves or on a binding element which
has been previously provided round the edge of the bundle to
be bound.
Such a method is advantageous in that a bundle of loose leaves
can be joined in a very simple and fast manner, for example
by means, of stapling, and in that this bundle can then be
fixed in a cover without having to make use of expensive
manufacturing devices.

To this end, the present invention concerns a method for
binding a bundle of loose leaves or the like in a cover
with a back, characterised in that it mainly comprises the
following steps:
binding a free edge of the above-mentioned bundle of
loose leaves ;
- providing a strip of glue on the above-mentioned bundle
of loose leaves near the above-mentioned free edge of the
bundle of leaves and at a distance of this free edge which
is almost equal to or somewhat larger than the depth of the
back of the cover ;
providing a bundle of leaves with its bound edge
in the back of the cover and fixing this bundle in the
cover by means of the above-mentioned strip of glue.

The invention also concerns an end leaf which can be bound
together • with a bundle of loose leaves in a method according
to the invention, which end leaf is provided with a strip of
glue which has preferably been provided beforehand near a
free edge thereof. .
The—present—invention—also_concerns a cover which can be
applied in a method according to the invention whereby this
cover is provided with a back and two leaves and whereby, on
the insides of the above-mentioned leaves of this cover, is
provided a strip of glue
Finally, the invention also concerns a binding element which
can be applied in a method according to the invention,
whereby this binding element consists of a binding element
which has been folded or can be folded in a U- or V-shape,
which is provided with at least one strip of glue on its
outside and which is designed to be provided round the free
edge of the bundle of leaves to be bound before the latter is
provided in the cover.
In order to better explain the characteristics of the
invention, the following preferred method according to the
invention for binding a bundle of loose leaves or the like
is described, as well as an end leaf, coyer or binding
element applied thereby, with reference to the accompanying
drawings, in which:

figures 12 and 13, 14 and 15 respectively, represent a
variant of a method, according to figures 1 and 2;
figures 16 to 18 represent variants of a cover according
to figure 12.
As is represented in figures 1 and 2, in a method
according—to the—invention, a free edge of a bundle of
loose leaves 1 is bound first, for example as this free
edge is stapled with one or several staples 2.
WO 2007/039804 PCT/IB2006/002737

It goes without saying that the present invention is not
restricted to binding by means of stapling, but that also
other binding techniques can be applied such as stitching,
cold gluing, hot gluing, punching with plastic or metal rings
or the like.
Each time we hereafter talk about stapling, also other
binding techniques can be applied.
In this case, but not necessarily, use can be made of end
leaves 3 when binding, provided on the outsides of the
above-mentioned bundle of leaves 1 and which are made of a
relatively rigid, either or not flexible material which can
be stapled, such as for example cardboard, plastic or paper.
These materials may be single-layered, multilayered, coated
or laminated.
Next, the above-mentioned bundle of leaves 1 is provided with
its stapled edge in a cover 4 which in this case is built as
a U-shaped back 5 which is preferably made of metal, but
which can also be made of any other, preferably hard
material, such as for example ceramics, a rigid plastic,
or the like.
It is clear that the above-mentioned back 5 of the cover 4
can also be made of any flexible material whatsoever and
that this back 5 must not necessarily be U-shaped either.
Against the inside and outside of this back 5 is in this case
provided a coating 6, 7 respectively.
WO 2007/039804 PCT/IB2006/002737
6
The cover 4 is also provided with two preferably rigid
leaves 8 and 9 which are joined in a folding manner to the
above-mentioned back 5 on either side as they extend between
the above-mentioned coatings 6 and 7 as well.
According to the invention, the above-mentioned leaves 8 and
9 can be made of plastic or in the shape of an either or not
coated piece of cardboard or paper. These materials can be
single-layered, multi-layered, coated or laminated.
It is clear the that In a method according to the invention,
many types of covers can be applied, and |taht|,
consequently, the present invention is not limited to the,
use of a cover 4 of the type represented in figure 1.
On the insides of the above-mentioned leaves 8 and 9 is
provided a strip of glue 10 near the back 5 of the cover
4 which has been provided, beforehand ±n this case and which
can be covered by means of a removable foil 11.
In this case, the strip of glue 10 is realised with a
self-adhesive glue, but it is not excluded according to the
invention that this strip of glue 10 is realised by means of
a glue which can be thermally activated, i.e. what is called
a melting glue, or by means of a cold glue, which might be
useful should the method be applied on an industrial scale.
Every time glue is mentioned further in this description, any
type of glue is meant by it.
In order to fix the stapled bundle of leaves 1 in the cover
WO 2007/039804 PCT/IB2006/002737
7
4 in a final step of the method according to the invention,
the cover 4 -is folded up, after the above-mentioned foils 11
have been removed,. such that the bundle 1 is glued with its
outermost end leaves 8 and 9 onto the inside of the cover 4
by the strips of glue 10.
Since such a method according to the invention can merely use
a simple, ordinary stapler instead of expensive and complex
manufacturing machines, such a method is economical and is
particularly fit for small-scale or private applications.
It is clear, however, that the method according to the
invention is not restricted to small-scale applications and
that it is particularly fit for large-scale, industrial
applications, whereby use can be made of other binding
techniques than stapling, should that be necessary.
The term "strip of glue" should hereby be regarded in the
broadest sense and it is not restricted to a narrow
strip; on the contrary, it can also be realised as a
surface of glue which extends over the entire or .
practically the entire surface of the leaves 8 and/or 9.
Figure 3, represents |a variant of| the method according to
figure 1, whereby the above-mentioned strips of glue 10 have
been provided beforehand on the above-mentioned end leaves 3
which have been bound together, and in this case stapled
together with the bundle 1.
The strips of glue 10 are hereby preferably provided near
and parallel to the free edge of the end leaves 3, in
WO 2007/039804 PCT/IB2006/002737
8
particular at a distance which is almost equal to or somewhat
larger than the depth D of the back 5 of the cover 4.
In this case as well, the strips of glue 10 can be realised as
surfaces of glue, however, extending over the entire or
practically the entire surface of the end leaves 3.
It goes without saying that the end leaves 3 may have
practically the same format as the bundle of leaves to be
bound, in which case the cover 4 does not have to be
provided with an inner coating 6 or what are called "mirror
leaves" glued onto the insides of the leaves 8 and 9 of the
cover 4.
It is not excluded, however, for the end leaves 3 to be
made smaller than the bundle of leaves to be bound.
Figure 4 represents a binding element 12 according to the
invention which in this case mainly consists of a folding
element 13 which in this case, but not necessarily, is
made of a layer of cardboard and which is also provided
with folding lines 14.
The binding element 12 is also provided with two strips of
material 15 and 16 which in this case are part of this
binding element 12, but which can also be made in the shape
of separate strips of material which are connected to the
free ends of the folding binding element 12 in a folding
manner at folding or perforation lines 17.
On each of the above-mentioned strips of material 15 and 16
WO 2007/039804 PCT/IB2006/002737
9
is in this case provided a strip of glue 10 on the outside
of the folding binding element 12 which extends entirely or
partly over a respective strip of material 1.5 or 16 and
which, if required, can be covered with a foil 11.
It is clear that, according to the invention, the
binding element 12 must not necessarily be pre-formed, but
that one can also start with a flat element which is provided
with one or several strips of glue 10 on one side and which
is folded in the required U-shape before use, as is
represented in figure 4.
It is also clear that the above-mentioned strips of material
15 and 16 may have any dimensions whatsoever and that they
may be smaller than the leaves to be bound or almost equally
large as this bundle of leaves.
The method for binding a bundle of loose leaves 1 or the
like by means of a binding element 12 according to the
invention is very simple and is represented in figures 5 and
6.
As is represented in figure 5, the above-mentioned binding
element 12 folded in a U-shape is provided round a free edge
of a bundle of loose leaves 1, and this free edge of the
above-mentioned bundle of loose leaves 1 and the binding
element 12 provided around it are joined together by means of
one or several staples 2 in this case.
As is represented in figure 6, the bundle of leaves 1 is
subsequently provided with its bound, stapled edge in the U-
WO 2007/039804 PCT/IB2006/002737
10
shaped back 5 of a cover 4 and this bundle of leaves 1 is
fixed in this cover 4, to which end, in the given example,
the above-mentioned strips of material 15 and 16, after the
above-mentioned foils 11 have been removed, are glued
with their strips of glue 10 onto the respective insides of
the cover 4.
In the given example, the binding element 12 is made of
cardboard, but it is clear that this binding element 12 can
be made of many other materials, such as among others
paper, which can preferably be stapled and which can
preferably be folded as well so as to form a U-shaped
element or which have already been made according to
such a U-shape.
The example of binding element 12 represented in figure 4 is
provided with two strips of material 15 and 16, but it is
clear that the presence of such strips of material
15 and 16 is not required according to the invention,
and that the above-mentioned bundle of leaves 1 can also be
fixed in the cover 4, and particularly in the back 5 of this
cover 4, by means of a strip of glue which is provided on the
back of the U-shaped part of the binding element 12.
Nor is it excluded that merely one strip of material 15
or 16 is provided, onto which is provided a strip of glue
10, either or not combined with the presence of a strip of
glue on the back of the binding element 12.
The invention is not restricted to one embodiment of binding
element 12 whereby the strip of glue 10 merely extends over
WO 2007/039804 PCT/IB2006/002737
11
a part of the respective strip of material 15 or 16, but the
strips of glue 10 can also extend over the entire strips of
material 15 or 16, and they may even be provided on the
entire surface of the binding element 12.
Figure .7 represents another embodiment of a binding
element 12 according to the invention which is made in the
shape, of a pre-folded U-shaped mould made of a flexible
material, whereby the strips of material 15 and 16 are
integrally part of the binding element 12 and whereby,
thanks to the flexibility of the selected material, no
folding or perforation lines must be provided.
Figure 8 represents yet another possible embodiment of a
binding element 12 according to the invention, which
in this case is made V-shaped instead of U-shaped and which
is more appropriate for the binding of thin bundles of leaves
1.
It is clear that, in all the embodiments of binding element
12 which are represented in figures 4 to 8, the strip of glue
10 can only extend over a restricted width, or it can be
realised in the shape of a surface of glue which extends over
the entire or almost the entire surface of a respective strip
of material 15 or 16.
Figure 9 represents a variant of an end leaf 3 according to
the invention whereby this end leaf 3 is provided with a
fixing strip 18 on one side edge, for example made of
paper, which fixing strip 18 is fixed to the edge concerned
of the end leaf 3 by means of gluing in this case.
WO 2007/039804 PCT/IB2006/002737
12
According to the invention, only the side edge of the
fixing strip 18 to be bound is hereby fixed to the end leaf
3.
On the part of the fixing strip 18 which is not glued to the
end leaf 3, on the side turned away from the end leaf 3, is
provided a strip of glue 10 at a distance from the above-
mentioned side edge of the end leaf 3 to be bound according
to the invention.
On the above-mentioned strip of glue 10 is preferably
provided a removable foil 11.
Figure 10 represents the use of such an end leaf 3, whereby,
in this case, on either side of the bundle of leaves 1 to
be bound, is provided an end leaf 3 according to figure 9;
The end leaves 3 are hereby positioned such that their above-
mentioned fixing strip 18 is situated on the side edge of
the bundle of leaves 1 to be bound, and such that these
fixing strips 18 are turned outward,. away from the bundle of
leaves 1..
The bundle of leaves 1 is preferably joined together with the
end leaves 3 by providing staples 2 through the parts of
the fixing strips 18 that are glued to the end leaves 3.
After the bundle of leaves 1 and the end leaves 3 have been
bound together, for example by means of stapling, the foils 11
are removed from the strips of glue 10 and the stapled
bundle is provided in a cover 4 and glued to the inside
WO 2007/039804 PCT/IB2006/002737
13
of the cover 4 by means of said fixing strips 18.
As the part of the fixing strip 18 on which the above-
mentioned strip of glue is provided is not fixed directly to
the end leaf 3, the end leaves 3, when the cover 4 is opened,
are not opened as well,, which is the case with an end leaf as
represented in figure 3.
An advantage of such an end leaf according to figure 9 is
that the bundle of leaves always opens nicely and that the
presence of the staples 2 is not visible, as the end leaves 3
are not glued to the cover 4.
Another advantage of such an end leaf 3 is that, between
the cover 4 and the end leaf 3, the strip of glue 10 is
not visible as the end leaf's 3 own weight will not place a
load on the strip of glue 10 when opening the cover 4.
Figure 11 represents a variant of an end leaf 3 according to
figure 9, whereby the fixing strip 18 is in this case fixed to
the end leaf 3 as it is formed of a folded part of this end
leaf 3.
Such an embodiment of an end leaf 3 is advantageous in that
its production is very simple, as the fixing strip 18 must
not be glued to the end leaf 3.
The use of such an end leaf according to figure 11 is
analogous to that of the embodiment of figure 9.
WO 2007/039804 PCT/IB2006/002737
14
It is clear that in the embodiments of end leaf 3 which are
represented in figures 9 to 11, the dimensions of the fixing
strip 18 can be freely chosen, and that they may be just as
large as the dimensions of the leaves to be bound and the
coVer, or that they may be smaller.
It is also clear that the strip of glue 10 must not
necessarily extend over only a part of the fixing strip 18,
but that it may also be provided over the entire or
practically the entire surface of the fixing strip 18.
Figures 12 and 13 show a variant of a method according
to the invention, whereby the above-mentioned leaves 8
and 9 of the cover 4 are in this case made in the shape
of flexible strips of material, for example plastic,
paper or the like, which are glued onto the respective
inner sides of the legs of the U-shaped back 5.
Analogous to the cover which is represented in figure
1, a strip of glue 10 is provided on the insides of the
respective leaves 8 and 9, near the back 5 of the cover
4, which in this case has been provided beforehand and
which may be covered with a removable foil 11.
In order to bind a bundle of loose leaves 1, as is
represented in figure 13, this bundle of leaves 1 is
bound first, for example by means of staples 2, after
which the stapled bundle of leaves 1 is provided in the
back 5 of the cover 4 and is fixed there as the above-
mentioned leaves 8 and 9 are glued onto the bundle of
leaves 1 with their respective strips of glue 10.
WO 2007/039804 PCT/IB2006/002737
15
In the given examples, the leaves 8 and 9 of the cover
4 are always connectedto the legs of a U-shaped back 5
but, according to the invention, it is also possible
for these leaves 8 and 9 to be connected to a flat back
whereby, according to the invention, the above-
mentioned strip of glue 10 is provided on each of the
respective leaves 8 and 9.
Figures 14 and 15 represent another variant of a method
according to the invention, whereby use is made of a
binding element 19 according to figure 14 in this case.
The above-mentioned binding element 19 is in this case
made in the form of a strip of material 20 which is
preferably made of a material that can be stapled.
The above-mentioned strip of material 20 is provided
with a strip of glue 10 on at least one side which,
according to a preferred characteristic of the
invention, is situated at a distance A from a side edge
of the strip of material which is larger than the depth
D of the U-shaped back 5 of the cover 4.
Naturally, the above-mentioned strip of material 20 can
be made in any dimensions whatsoever and it may have
the shape, for example, of a leave having the same
dimensions as the bundle of leaves 1 to be bound.
The use of the binding element 19 according to figure
14 is represented in figure 15, whereby two such
WO 2007/039804 PCT/IB2006/002737
16
binding elements 19 are provided on each side of the
bundle of leaves 1 to be bound in this case and are
bound with the latter, for example by means of staples
2, such that these binding elements 19 with their
respective strips of glue 10 are turned outward, away
from the bundle of leaves 1 to be bound.
Next, the bound bundle of leaves is provided in the
cover 4, which is in this case provided with leaves 8
and 9 made of a flexible material, for example plastic,
paper or the like, and the respective strips of glue 10
are glued onto a respective leave 8 or 9.
Figure 16 represents a variant of a cover 4 according
to figure 12, whereby the back 5 is not provided with a
coating in this case, and whereby leaves 8 and 9 are
glued onto the respective insides of the legs of the
back.
The leaves 8 and 9 are preferably made of a flexible
material such as paper or plastic.
According to the invention, a strip of glue 10 is
provided on each of the above-mentioned leaves 8 and 9
which is preferably, but not necessarily provided with
a foil 11.
A method for binding a bundle of loose leaves in such a
cover 4 is identical to the method which is represented
in figures 1 and 2, 12 and 13 respectively.
WO 2007/039804 PCT/IB2006/002737
17
Figure 17 represents another embodiment of a cover
according to figure 12, whereby the leaves 8 and, 9 are
in this case formed of parts of the coating of the back
5 which extend past the far ends of the legs of the
back 5, and which are glued onto, each other.
It is clear that the leaves may also be formed by using
only the outside coating of the back 5, as is
represented in figure 18, or only the inside coating of
the back 5.
The dimensions of the leaves 8 and 9 may be freely
selected according to the invention and must not
necessarily be equal to the dimensions of the bundle of
leaves to be bound, but they may also be formed, as
represented in figure 18, of a thin strip of material.
Analogous to what has been described above, the strip
of glue 10 may be made of a self-adhesive glue in the
case of the embodiments of figures 16 to 18, but it is
not excluded according to the invention for this strip
of glue 10 to be made in the form of a glue which is
thermally activated, also called a hot melt glue, or in
the form of a cold glue.
The present invention is by no means limited to the
method and end leaf 3, cover 4 or binding element 12 given
as an example and represented in the figures; on the
contrary, such a method according to the invention for
binding a bundle of loose leaves 1 or the like, and an
end leaf 3, cover 4 or binding element 12 applied thereby,
WO 2007/039804 PCT/IB2006/002737
