    Method for binding a bundle of sheets, book or farde obtained therewith, bundle sheets, method and device for forming such bundle sheets.
    The present invention relates to a method for binding a bundle of sheets, for example for forming a book or the like, in particular for obtaining a book or farde, the sheets of which can be flattened open and the printing seamlessly over the two folded sheets open continues. The latter is especially desirable for compiling photo albums, magazines and the like with photos and illustrations that run across the full width of the opened book.
    Traditionally a book is compiled from booklets of a number, for example sixteen, folded pages. In the middle these quires are sewn along the fold line and the backs of a number of quires are sewn together on the outside.
    This whole is then glued to a mesh. Because the mesh is very flexible, this will ensure that the sheets are flat after opening the book.
    Double-folded sheets are always required to produce a sewn book.
    A drawback is that such books cannot be used for the manufacture of, for example, a photo album, because the printing machines or printers for printing the sheets of a photo album work with pre-cut sheets of photo paper.
    Such pre-cut sheets cannot be sewn to form a photo album.
    There are also books made from a bundle of single, not folded pages.
    It is classical that a book composed of a bundle of single sheets is made by gluing one edge of the bundle of single sheets.
    To make this binding strong in such a way that when opening and closing the book no sheets come loose, the bundle of sheets will always be in the glue over a limited distance, for example half a millimeter, so that the glue also ends up between the sheets of the bundle .
    Current glues are very flexible in such a way that they allow the book to be opened completely flat after gluing, without the sheets coming off.
    However, by fully folding the book open, the glue that has ended up between the sheets during gluing will be clearly visible.
    This visible glue is disturbing when the printing of the sheets extends to the binding. After all, this glue will have ended up over the printing and there will reduce the aesthetic appearance of the printing.
    Sheets are already known with an integrated, laminated and printable hinge, which allow binding of a bundle of these sheets to form a book or the like, the sheets lying flat after opening of the bundle.
    However, the manufacture of such sheets is an expensive process and the processing is labor intensive.
    The present invention has for its object to provide a solution for one or more of the aforementioned and other disadvantages.
    The present invention has a method for binding a bundle of sheets into a binding back as an object, wherein the bundle is arranged with an edge of the blades in the binding back and is fixed therein, wherein for binding a bundle of sheets is used of which a strip of the sheets, each separately, was previously double folded along the same line to form a fold line extending parallel to and at a distance from the aforementioned edge.
    An advantage of such a method is that the fold line allows the sheets to be folded along this fold line when the book is opened and that when the bundle of sheets is bound in the spine, the sheets with their sharp fold lines abut each other, so that the sheets can be flat can be folded open and that a print over the two adjacent fold lines can run almost seamlessly over open folded sheets.
    Another advantage is that when the bundle is folded open, there is no gap between the folded sheets, so that the glue or stitching or staples used to tie in the bundle in the back are not visible and therefore not disturbing the printing that runs from one sheet to the other.
    Use is preferably made of a bundle of sheets, the strip of which is folded back from the sheets into the plane of the sheets.
    As a result, binding will be smooth, accurate and easy and this in the same traditional way as a traditional bundle without folded sheets.
    Furthermore, the distance between the folding line and the edge of the sheets is preferably chosen such that when opening the bound bundle, the opened sheets extend flat or almost flat.
    By plane is meant here that the plane of one blade lies in the plane of the other blade, such that the whole of both blades extends in one plane so that the whole of both blades can be considered flat or substantially flat.
    This will, for example, facilitate reading of text printed on the sheets because they do not bulge on the binding side. For photos printed on the sheets, the non-bulging of the sheets on the binding side will increase the aesthetic character.
    According to a preferred feature, all the sheets in the bundle are double folded at the same distance from the edge to be bound.
    An advantage of this is that, with the help of machines, the folding can easily be automated.
    This will be applied in particular to sheets that have been folded over beforehand.
    However, the aforementioned distance may also be different for the different blades of the bundle. For example, the distance for the first leaf can be twelve millimeters. For the second leaf this can be twelve millimeters plus the thickness of a leaf. For the third leaf the distance is twelve millimeters plus about twice the thickness of a leaf. The distance then increases further up to the center of the bundle of blades, then decreases symmetrically to a distance of twelve millimeters before the last leaf of the bundle.
    According to a preferred feature, the binding spine is a V-shaped or U-shaped spine and the distance between the folding line and the edge of the blade substantially corresponds to the depth of the spine, this distance preferably being slightly greater than the depth of the spine.
    This has the advantage that the sheets can be folded over the binding spine at the height of the fold line when the bundle is fixed in the binding spine.
    According to a preferred feature, the aforementioned distance is between 10 and 14 mm and preferably 12 mm.
    According to a preferred feature, the binding back is a metal binding back which is provided with a hot-melt adhesive that is melted during binding in order to retain the sheets along their aforementioned edge after solidification.
    An advantage of this is that this method allows fast and practical fixing of the bundle in the binding spine. Because the sheets fold at the height of the fold line, the glue on the edge will not be visible when the bundle is opened.
    Preferably, the legs of the metal binding spine are squeezed close together after applying the bundle to clamp the bundle in the binding spine.
    This has the advantage that the bundle is firmly anchored in the binding back. Moreover, the pinched binding spine will hold the blades together when the bundle is opened so that the blades lie against each other with their folding lines and there will moreover be no gap between the bundle and the edges of the legs of the binding spine, so that glue and the like are visible withdrawn.
    According to a preferred feature, the bundle is stapled before binding.
    An advantage of such a method is that in principle no glue is required to hold the bundle in the binding back, it is sufficient to place the bundled staple in a binding back and then squeeze the binding back shut, so that the bundle is clamped in the binding back .
    According to a preferred characteristic, the sheets are previously provided with a print which extends to the aforementioned folding line.
    According to a preferred feature, the sides of adjacent sheets facing each other are previously provided with a print which, as it were, seamlessly overflows from one side to the other side for which the part of the print is arranged on one side is arranged on the fold line of the relevant sheet and the part of the printing from the other side up to the fold line of the adjacent sheet.
    An advantage of this is that the printing, for example a photograph, can extend over two sides of adjacent sheets. Moreover, the printing must not extend as far as the aforementioned edge, so that printing of the sheets is easier.
    The printing on one side and the printing on the other side preferably overlap the fold line with an overlapping portion.
    This has the advantage that when the bundle is opened, a thin unprinted line will not be visible at the level of the folding lines, when, for example, a slight deviation or inaccuracy has occurred during the double folding of the sheets or during binding of the bundle.
    In a preferred embodiment, one or two end sheets of a farde or book are arranged on the binding spine.
    This front cover has the advantage that it will protect the printing on the outer side of the outer blades of the bundle against damage or wear.
    Preferably, the bracts can be completely folded outwards relative to the legs of the binding back to against or almost against the legs of the connecting back.
    This will ensure that the binding spine is rotatable during scrolling through the bundle about an axis parallel to the fold line.
    As a result, the blades will lie flat while browsing the bundle.
    The invention also relates to a bundle of sheets, wherein a strip of the sheets is each individually double folded along the same line to form a folding line that extends parallel to and at a distance from an edge.
    The blades of the bundle are preferably flat, because the strip of the blades is each individually folded back into the plane of the blade and the aforementioned distance is between approximately ten and fourteen millimeters.
    It is not excluded that this distance is greater, for example 15 or 20 millimeters.
    The invention also relates to a book or farde with a binding spine and a bundle of sheets bound therein, wherein the bound bundle is a bundle according to the invention.
    Furthermore, the invention also relates to a method for forming a bundle of sheets according to the invention, wherein each sheet of the bundle is individually folded double by applying the following steps: clamping a sheet to be folded between two sheets with the exception of one width strip extending between the plates, partial folding of the projecting strip in a direction perpendicular to the plane of the blade, further folding of the strip by pushing the plates with the partially folded strip into the funnel-shaped groove or between two rolls with resilient or fixed suspension or by moving the profiled element with the funnel-shaped groove over the edge of the plates, moving the funnel-shaped groove apart and the plates with the folded strip, folding the folded strip back into the plane of the blade and further into a partially folded state of the strip on the opposite side of the plates, the further folding of the strip by pushing the plates with the partially folded strip into the funnel-shaped groove or between two rollers with resilient or fixed suspension or by sliding the profiled element with the funnel-shaped groove over the edge of the plates. and then pull it out again and straighten the folded strip back into the plane of the leaf.
    Such a method will allow for a folding sheet to be double folded along the same line.
    The invention also relates to a device for applying the method for forming a bundle of sheets according to the invention, wherein the device is provided with clamping means for clamping each sheet of the bundle along a line at a distance from the edge of the blade for forming a protruding strip of width equal to the aforementioned distance and of folding means for completely or almost completely folding this strip along the aforementioned line relative to the clamping means to form a folding line at the aforementioned distance from the edge of the sheet.
    In a preferred embodiment the clamping means are formed by two plates between which each sheet can be clamped, each with an edge aligned on the line along which the sheet is to be folded.
    By clamping the sheet between two plates, it will be possible to fold the sheet twice along the same line to form a folding line.
    These plates can for instance be made of steel and have a thickness of 0.3 millimeter.
    The folding means are preferably formed by a profiled element with a funnel-shaped groove that extends in a direction parallel to the plane of the sheet to be folded over.
    In a preferred embodiment, the device is provided with means for displacing the folding means and the clamping means with the blade clamped therein relative to one another in a direction parallel to the plane of the sheet to be folded between a position where the sheet to be folded is located is in line with the funnel-shaped groove and a position where the blade is in the funnel-shaped groove with the aforementioned strip up to the bottom of the funnel-shaped groove.
    Preferably, the device is further provided with means for perpendicularly folding the strip of the clamped sheet relative to the clamping means before placing the sheet in the funnel-shaped groove.
    These means are formed, for example, by the fact that the clamping means are provided with a drive that allows the clamping means to be displaced relative to the folding means in a direction perpendicular to the plane of the blade.
    The means for moving the folding means and clamping means relative to each other in a direction parallel to and perpendicular to the plane of the blade allows automatic folding of the blades.
    In a preferred embodiment, the folding means are provided at the entrance of the funnel-shaped groove with two or more rollers with resilient or fixed suspension between which the blade can move in the groove.
    The dimensions of these rollers can be such that they can touch each other. When the rolls are made of metal, they are provided with a resilient suspension in order to allow the plates to pass between the rolls. When the rollers are made of rubber or a similar material, they can be provided with a fixed suspension.
    In this way the blade is not exposed to sliding or abrasive movements when it is moved into the groove, but the rollers will roll over the surface of the blade. As a result, the printing on the surface of the sheet will not be damaged.
    With the insight to better demonstrate the characteristics of the invention, a preferred method for binding a bundle of sheets according to the invention is described below as an example without any limiting character, with reference to the accompanying drawings, in which:
    Figures 1 to 7 schematically show the successive steps of a method according to the invention; figures 8 to 10 schematically represent the bundle from figure 7 during the browsing. figure 11 schematically represents a view according to the arrow F11 in figure 7; figure 12 schematically shows the folded sheets of figure 11, but in a loose removed state; Figure 13 schematically represents an alternative embodiment of Figure 12; Figure 14 schematically represents a device for sharply folding a sheet in two; figures 15 to 23 schematically show the different steps of the use of the device, as shown in figure 14; Figures 24 to 26 schematically show an alternative device for sharply folding a sheet and various steps of use of such a device.
    Figures 1 to 4 schematically show a method for manufacturing a double-folded sheet 1.
    To this end, a sheet 1 with an edge 2 along a fold line 3, which runs parallel to the edge 2 and at a distance A from it, is folded in one direction as can be seen in Figure 2. In this way a strip 4 is formed which is delimited by a folding line 3.
    Subsequently, the strip 4 is folded in the other direction according to the sharp folding line 3 as can be seen in figure 3.
    Finally, as shown in Figure 4, the strip 4 is folded back in line with the blade 1.
    A double-folded sheet 1 is made in this way.
    Preferably, the strip 4 is completely double folded to form a sharp folding line 3. In this way, the folding line 3 forms, as it were, a flexible hinge along which the blade 1 can be turned back and forth smoothly relative to the strip 4.
    The distance A between the edge 2 and the folding line 3 is equal to the width of the strip 4.
    Figures 5 to 7 schematically show a method for binding a bundle of 5 folded sheets 1.
    As can be seen in Figure 5, the bundle 5 consists of a number of double-folded sheets 1 placed with their sides 6 against each other, the edges 2 of the sheets 1 to be bonded being aligned with respect to each other.
    The binding back 7 in this case consists of a U-shaped part 8, for example of metal, with a layer of hot melt adhesive 10 on the bottom 9.
    The tie-back 7 is further provided with two end leaves 11, for example from cardboard which are provided with a covering 12 on either side.
    It is clear that the binding back 7 can also take other forms.
    The bundle 5 is placed in the U-shaped part 8 of the binding spine 7, the edges 2 of the double folded sheets 1 being placed against the layer of hot melt adhesive 10, as shown in Figure 6.
    The folding line 3 of the double folded sheets 1 here slightly exceeds the U-shaped part 8.
    Subsequently, the layer of hot-melt adhesive 10 is heated by means of a heat source 13. The hot-melt adhesive 10 will hereby melt and become liquid, whereby the double-folded sheets 1 of the bundle 5 can be inserted into it.
    After solidification of the hot-melt adhesive 10, the bundle 5 is attached to the bundle 7 via the hot-melt adhesive 10.
    Subsequently, as can be seen in figure 7, the legs 14 of the U-shaped part 8 of the binding back 7 are pinched towards each other. This will ensure an extra firm fixation of the bundle 5 in the binding spine 7 and for connecting the bundle 5 to the free edges of the legs 14 without a gap being visible between the two.
    The bundled bundle 5 is now finished into a farde with bound sheets 1.
    As can be seen in Figure 7, when bundle 5 is opened, the double-folded sheets 1 will extend in one plane.
    In reality, the result is better than in the figures shown, which give a somewhat distorted image because the sheets were given a certain thickness for clarity.
    Figures 8 to 10 schematically show how the U-shaped part 8 of the binding spine 7 will rotate during browsing.
    When a front cover 11 is opened, it will be possible to fold it against the leg 14 of the U-shaped part 8, as can be seen in figure 8.
    When leafing continues, the leg 14 of the U-shaped part 8 will move away from this end leaf 11 because the U-shaped part 8 will rotate in the direction of the arrow B towards the other end leaf 11. This is shown in Figure 9.
    When further browsing, as shown in Figure 10, the U-shaped part 8 of the binding spine will continue to rotate until the other leg 14 of the binding spine 7 is finally against the other end cover 11.
    This turning of the binding spine 7 happens, as it were, automatically during the scrolling of the bundle 5 and will ensure that the blades 1 extend flat when the bundle 5 is opened on a certain page.
    As shown in Fig. 11, the sides 6 of the double-folded sheets 1 are printed, for example with a part of an image 15 or photo, the image 15 almost seamlessly merging from one double-folded sheet 1 to the other double-folded sheet 1 so as to form one continuous illustration. This is useful, for example, when compiling a photo album in which in this way large photos can be provided that extend over two sheets 1, and this without an annoying gap between them.
    Figure 12 shows two printed doubly folded sheets 1, the printing 15 on both sheets 1 after binding together will form one whole.
    The printing 15 is hereby pressed up to the folding line 3, wherein the strip 4 remains unprinted.
    Figure 13 shows a variant thereof, wherein also a part 16 of the strips 4 is printed with an overlapping part of the printing 15.
    It is clear that the hot melt adhesive 10 can be dispensed with, and that the bundle 5 can be stapled before placing it in the binding spine 7.
    It is also clear that pinching the legs 14 of the U-shaped part 8 of the binding back 7 can be omitted.
    A device 17 for forming a bundle of 5 sheets 1 according to the invention is shown in Figure 14.
    The device 17 is provided with two plates 18, in this case steel plates with a thickness of 0.3 millimeter, which serve as clamping means 18.
    The two plates 18 are arranged between two plates 18b. These plates 18b are movable relative to the blade 1 which is clamped between the two plates 18. The plates 18 are not movable relative to the blade 1.
    A sheet 1 is clamped between the two plates 18 which are aligned with their edge 19 on a line 20 at a distance A from the edge 2 of the sheet 1 to form a protruding strip 4 of width A.
    Furthermore, the device 17 is also provided with a profiled element 21 with a funnel-shaped groove 22, which serves as a folding means 21.
    At the entrance 23 of the groove 22 there are two rotatable rollers 24. The bottom 25 of the funnel-shaped groove 22 ends in a sharp point 25.
    Furthermore, the device 17 is also provided with means for displacing the plates 18 relative to the element 21 in a direction XX 'parallel to and in a direction YY' perpendicular to the plane of the blade 1, which are not shown for simplicity .
    The successive steps of a method for forming a bundle of 5 sheets 1 according to the invention in which the device 17 is used is shown in figures 15 to 23.
    Figure 15 shows how a sheet 1 is clamped between the two steel plates 18, a strip 4 of the sheet 1 with width A protruding between the steel plates 18.
    The plates 18 with the blade 1 are located above the element 21 in such a position that the strip 4 passes the entrance 23 of the element 21.
    The plates 18 are then moved towards the element 21, in which way the strip 4 of the blade 1 is partially folded upwards as shown in Figure 16.
    When the plates 18 are at the level of the funnel-shaped groove 22, they will then move in the groove 22, as shown in FIG. The plates 18b will hereby not move along in the funnel-shaped groove 22, but will remain in place.
    The rollers 24 will hereby ensure that the blade 1 between the plates 18 is guided smoothly into the groove 22.
    When the plates 18 are located as far as possible in the bottom 25 of the groove 22, the strip 4 over the line 20 will be folded upwards over the edge 19 of the plates 18, resulting in a sharp folding line 3.
    The plates 18 will then move back out of the groove 22, and will, as it were, slide back into the plates 18b. The folded-over strip 4 is folded back into the plane of the sheet 1 with the aid of the plates 18b, as represented in figure 18.
    The first sharp folding line 3 is formed. To fold the strip 4 over this folding line 3 in the other direction, upwards, over the same line 20, similar steps are carried out, as represented in Figures 19 to 23.
    The plates 18 with the blade 1 are located under the element 21 in such a position that the strip 4 passes the entrance 23 of the element 21.
    The plates 18 are then moved towards the element 21, in which way the strip 4 of the blade 1 is partially folded downwards as shown in Figure 20.
    When the plates 18 are at the level of the funnel-shaped groove 22, they will then move in the groove 22, as shown in Figure 21. The plates 18b will hereby not move along in the funnel-shaped groove 22, but will remain in place.
    The rollers 24 will hereby ensure that the blade 1 between the plates 18 is guided smoothly into the groove 22.
    When the plates 18 are located as far as possible in the point 25 of the groove 22, the strip 4 will be folded down over the line 20 over the edge 19 of the plates 18, whereby a sharp folding line 3 is created.
    This sharp folding line 3 will be formed on the same line 2 as the previous folding line 3. In other words, a sharp double folding line 3 is made in this way.
    The plates 18 will then move back out of the groove 22, and will, as it were, slide back into the plates 18b. The folded-over strip 4 is folded back into the plane of the sheet 1 with the aid of the plates 18b, as represented in figures 22 and 23.
    In this way a sharp, double folded sheet 1 can be made.
    By using the plates 18 it can be ensured that the strip 4 is folded twice along exactly the same line 20.
    The use of the funnel-shaped groove 22 then ensures the sharp folding line 3.
    It is clear that there can still be several rollers 24 in the funnel-shaped groove 22, or that there are no rollers 24 at all.
    It is also clear that the method can also be carried out by first performing the steps as shown in figures 19 to 23 and then the steps as shown in figures 15 to 18, in other words by first folding the strip 4 downwards up and then upwards.
    Figures 24 to 26 describe an alternative embodiment of a device 17 according to the invention, wherein in this case the plates 18 with the clamped leaf 1 and the profiled element 21 are displaceable relative to each other in only a single direction, namely in the direction of the plane of the blade 1, wherein the plates 18 are arranged opposite the entrance 23 of the funnel-shaped groove 22.
    The means for folding the strip 4 of the clamped sheet 1 at right angles to the plates 18 are in this case formed by a separate element 26, for example a pin 26, which is arranged movably between the plates 18 and the profiled element 21 in a direction YY 'perpendicular to the plane of the plates 18 and extending parallel to the edge 19 of the plates 18.
    In addition, the bottom 25 of the funnel-shaped groove 22 can be open, the width C of the opening 27 being slightly wider than the thickness D of two plates 18 with clamped sheet 1.
    The use of such an alternative embodiment differs in that in this case the strip 4 of the blade 1 is folded over by, before the plates 18 are placed in the funnel-shaped groove 22, to move the element 26 up or down from one side of the plates 18 to the other side of the plates 18 in order to first fold the projecting strip 4 up or down perpendicularly. The element 26 hereby moves from one position on one side of the plates 18 to a next position of the plates 18, the two positions being situated at a perpendicular distance E of the plates which is smaller than the width A of the strip 4 such that when the plates 18 move into the funnel-shaped groove 22, the folded strip 4 catches behind the element 26.
    When the plates 18 move in the funnel-shaped groove 22, they will be able to move beyond the bottom 25 with their edge 19 because of the opening 27 in the bottom 25. This will result in a very sharp folding line 3 being formed.
    The present invention is by no means limited to the embodiments described by way of example and shown in the figures, but a method for binding bundles of sheets according to the invention can be realized in various variants without departing from the scope of the invention.
