Description

PCT/132012/001135 Moreover, in this way the adhesive can be applied uniformly, without there being local zones with a surplus or shortage of adhesive.

Additionally a pretective ng' of the adhesive layer is not needed, e this is not sticky at the normal ambient temperatures.

Because the constituent parts of the support are entirely or partially surrounded by the cover, these constituent parts always ve their correct .position with respect to one another, and thus also when the t is heated to liquefy the hot—melt adhesive in order to affix the finishing cover.

In a red embodiment the layer of hot-melt adhesive is sufficiently thin so that it doesn't flow out when a finishing cover is applied under pressure.

This results in achieving good adhesion despite the use of a minimal quantity of adhesive.

In practice this means that the layer is thinner than 50 micrometres In order to obtain suffient adhesive strength, the layer is entially thicker than 20 micrometres, and is more preferably between 25 and 35 micrometres.

Preferably the layer of hot—melt adhesive is applied to the support by means of a sheet that is bonded to the support, W0 2012/172404 - 2012/001135 and the side turned away from the support is provided with the layer of hot—melt adhesive concerned beforehand.

The sheet with the hot—melt adhesive can be affixed, for example, by machine using a Kolbus adhesive machine or similar during the production of the element It is a virtue of the invention to be able to use such an t to cture a display board, whereby in this case the aforementioned ing cover is a poster, for example an advertising poster, a calendar, a photograph or similar .

The present invention also relates to a method for manufacturing a binding folder or a display board, which starts with an element according to the invention as described above, and whereby, to manufacture the binding folder or the display board, a printed or unprinted finishing cover or a poster is affixed with the ted side covering the layer of hot—melt ve of the support and bonded thereto Iby g the hot-melt adhesive in order to allow it to melt, and then letting it cool down again in order to enable the hot—melt adhesive to solidify again .

In a preferred variant the finishing cover is bonded to the support under pressure.

This produces an improves adhesion of the finishing cover on the support .

W0 2012/172404 PCT/IBZOIZ/001135 In order to manufacture a binding folder, additionally the central strip can be deformed into a U—shaped back, if desired .

An advantage is that this method is very user—friendly as a user does not require any skill or professional knowledge and the Iapplication of the method does not require qualified and d personnel.

This starts, for example, with a stock of primarily flat semi—finished elements and a stock of, preprinted or ise finishing covers or posters, whereby to form the binding folder according to choice, a combination is made from these aforementioned stocks in order to compose a binding folder or a display board according to the desire of the end user.

Optionally, on the side of the support opposite_ the side with the layer of hot-«melt »adhesive, an onal finishing cover is affixed that is provided with a hot-melt adhesive with which this additional finishing cover is affixed to the support, and then the t with the ing cover is heated and cooled to secure the finishing cover to both sides of the support.

In order to bind a bundle of leaves in the binding folder, the element can for e be provided with an adhesive strip beforehand, or after forming the back, a ring system can be secured in the back.

' PCT/[82012/001135 For the display board, optionally a hanging system or a stand is fastened to the back of the display board in order to hang the display board or position it somewhere in an upright position.

With the intention of better showing the characteristics of the invention, a few preferred embodiments of an element according to the ion are bed hereinafter by way of an e, without any limiting nature, with reference . to the accompanying drawings, wherein: figure 1 shows a schematic perspective view of a practical embodiment of an element according to the invention to form a binding folder; figure 2 shows a bottom view according to arrow F2 of - figure 1; figure 3 shows a cross-section according 'to the line III-III of figure 2 on a larger scale; figures 4 to 8 schematically show a few steps of the method according to the invention, making use of an element according to figure 1; s 9 and 10 show alternative embodiments of an element according tothe ion.

The element 1 according to the invention to form a binding folder shown in figures 1 to 3 is a semi—finished product that primarily consists of a flat support 2 that is formed by a central flat strip 3 and two flat sheets 4 on either side of the aforementioned strip.

W0 2012/172404 PCT/IBZOlZ/001135 Furthermore, the central strip 3 is ed to later form the back of the binding folder and the two sheets 4 are intended to form the endpapers of the binding folder. In the example shown, the strip 3 is thinner than the sheets 4, but this does notnecessarily have to be the case.

The support 2 has a cover 5 that is over or around the central strip 3 and sheets 4.

The cover 5 can lae manufactured frOHl paper or cardboard.

However it is preferable to have a cover 5' of white, black or coloured paper, preferably paper with a density of 90 gram/m 2 .

It goes without saying that the invention is not limited to this, and that other materials such as linen can also be used as a cover 5.

Of course it is also possible for the cover 5 to have a number of parts and that a different al is chosen for each side of the support 2, for e.

Preferably, at the location of the connection of the strip 3 with a sheet 4, the cover 5 forms a hinge 6 between these elements 3, 4 .

Although in the example of figures 1 to 3 , the sheets 4 and the l strip 3 , are connected together on the top and underside by a cover 5 , according to the invention it i s not ruled‘ out that the cover' 5 is only on one side, and only a folded—back part of this cover 5 is folded back over W0 2012/172404 the edges of the element 1 and secured to the other side of the element along the edges.

According to the invention, the t 2 is provided with a layer of hot—melt ve 7 on one side that extends. to a distance D from the edges 8 of’the support 2, all such that on the side concerned of the support 2 an edge 9 is obtained that is free of hot—melt adhesive 7 .

The hot-melt ve 7 preferably extends to a distance D a few millimetres from the aforementioned edge 8 of the support 2, for example around two millimetres from the edge The layer of hot—melt adhesive 7 is preferably applied to the support 2 by means of a sheet 10 that is bonded to the support 2 during production of the element and that the side of the sheet 10 turned away from the support 2 is provided with the layer of hot—melt adhesive 7 ned beforehand.

.The sheet 10 with the hot—melt adhesive 7 on it is bonded to the t 2'during production, for example by means of an adhesive machine of the Kolbus® make or similar.

In a practical embodiment of the invention, the element 1 is provided with an adhesive strip 11 for the subsequent securing of a bundle of leaves in the binding .

In a practical embodiment of the invention, the adhesive strip 11 can be provided in the form of a strip of heat- sensitive hot-melt adhesive, and the central strip 3 is made of metal, steel or other thermally conductive material, all such that when binding the bundle of leaves the heat supplied is conducted well.

In an alternative embodiment of the invention not shown in the drawings, the adhesive strip 11 can_ also be in the form of a self—adhesive strip, that may or may not be protected by a thin protective sheet, and this tive layer can be easily d by the user for binding a bundle of leaves The adhesive strip 11 can be d to the cover 5 at the location of the central strip 3, or directly to the central strip 3 in the absence of a ng layer 5.

»The method for manufacturing a binding folder by means of an element 1' according to the invention is very simple and is illustrated on the basis of figures 4 to 7.

In a first step a desired element 1 and a suitable finishing cover are selected from a stock by the user.

The user. can choose this finishing cover 12 as desired and it is clear' that many materials, such as paper or cardboard, are suitable for this purpose. This ing cover 12 can be printed beforehand or otherwise, or if desired can be printed locally. It goes without saying that other materials such as leather, linen, plastic or similar can be used as a finishing cover 30.

PCT/182012/001135 The finishing covers 12 have dimensions that are primarily equal to the dimensions of the periphery of the layer of hot—melt adhesive 7 on the support, all such that the finishing cover can completely cover the layer of hot—melt adhesive 7 and the finishing cover 12 extends to a few etres from the edge 8 of the support.

The finishing cover is then affixed with the unprinted side covering the layer of hot—melt adhesive 7, as shown in figure 4, and bonded thereto by heating in order to melt the hot—melt adhesive 7 and then allowing it to cool again in order to solidify the hot—melt adhesive 7.

In practice a hot-melt adhesive 7 is used whose melting temperature is lower than .the temperature at which the traditionally used toner s and printing inks are damaged, so as not to damage any print on the finishing cover .

Optionally, as illustrated in figure 5, on the side of the support 2 opposite the side with the layer of lt adhesive 7, an additional ing cover 13 can also be applied that is provided with a hot—melt adhesive 14 with which this additional finishing cover 13 is affixed to the support 2.

By heating and cooling, this additional cover can be bonded to the t 2.

As shown in figure 6, the heating can be realised for example by moving the support 2 with a finishing cover 12 W0 2012/172404 i and/or 13 between heated rollers 15 on one or both sides of the support 2 in order to melt the hot—melt adhesive 7 and which also exert a certain pressure on the finishing cover 12 and 13, if need be followed by cooled rollers 16 to solidify the hotwmelt ve 7 more quickly.

During this heating operation, when there is an adhesive strip 11 of hot—melt ve, this adhesive strip 11 can be shielded from heat during the g process.

If desired the finishing cover 12 and/or 13 are first provisionally secured to the support 2 by local heating at a few points to keep the finishing covers perfectly in place when they are moved between the rollers 15 and/or 16. atively, the support 2 with the finishing covers 12 and/or 13 can be pressed between two heated s to affix the finishing covers.

In the embodiment shown, the additional finishing cover 13 is formed by two half additional finishing covers on either side of the central strip 3 of the support 2, but it is of course also possible to provide the additional finishing cover 13 in the form of one continuous additional cover, which in this case also extends over the central strip 3.

Preferably use is made of an additional finishing cover 13 whose dimensions are chosen such that the additional finishing cover 13 extends to a few millimetres from the edge 8 of the support 2, for example up to around two millimetres from the edge 8.

W0 72404 20121001135 It is clear that in this case there are no overlaps of the' covers 12 and 13 and thus a thicker edge does not occur as in the known. elements, as described. in the Belgian patent No. 1.018.467.

A possible last step is illustrated on the basis of figures 7 and 8, whereby the central strip 3 is deformed into a U- shaped back 17, for example by means of a stamp 18.

A binding folder 19 is thus ed, as shown in figure 8, with. a U-shaped. back 17 with an adhesive strip 11 therein and two endpapers 20.

Such a binding folder 19 can be used to bind a bundle of leaves 21 in. a known way 'by inserting a free edge 22 of this bundle into the back 17, and heating this back 17 with suitable equipment to make the adhesive strip 11 liquid, and. byr pressing the edge 22 into the molten adhesive and allowing it to cool in order to solidify the ve again.

In an ative embodiment of the invention, as shown in figure 9, the support 2 can be constructed as a continuous flat sheet 23, for example cardboard, and cutaways 24 are made in this sheet 23 to demarcate a central strip or sheet section 3 from which the back can be formed, flanked by two .sheet sections 3 that will form the endpapers.

Of course it is not ruled out that a number of cutaways 24 are provided in the sheet 23.

PCT/132012/001135 In this example, a ring mechanism 25, instead of an adhesive strip 11, is secured to the central strip 3, with which a bundle of ated leaves can be bound in the folder.

It is clear that a method ing to the ion is within reach of everyone and thus does not require highly qualified skilled workers.

Moreover, the method enables g folders 19 with a very professional appearance to be realised in a very flexible way, whereby it can start locally with a stock of elements 1' that can be covered according to choice with printed or unprinted finishing covers 12 to be selected from a stock, and optionally an additional finishing cover 13 also to be ed from a stock of covers 13 that are already provided with a hot—melt layer 14.

The drawings only show the invention schematically and the proportions between the different elements, primarily the thicknesses, have been drawn out of proportion, only for the purpose of being able to better explain the invention .on the basis of the drawings.

Figure 10 shows an alternative embodiment of an element 1 according to the invention, which in this case is intended for manufacturing a display board.

In this case the t 2 is formed by a single completely flat continuous sheet 23 that is provided with a cover 5, whereby in this case the support 2 is also provided with a layer of hot—melt adhesive 7 on one side that extends up to a ce D: from the edges 8, and this to affix a finishing cover 12 in the form of a poster or similar on this side of the support 2.

The further method to affix a poster to the element is analogous to the method bed above on the basis of figures 1 to 6.

Additionally, a hanging system. 26 can be fastened to the back of the y board to be able to hang the display board, or alternatively a stand not shown in the drawings in order to be able to place the display board ere in an upright position.

The present invention is by no means limited to the variants described as an example and shown in the drawings, but an element for manufacturing a- binding folder and a method applied thereto can be realised in Hall kinds of variants, without departing from the scope of the invention.
