[0003] The object of the invention is to design this method such:
- that the pages come to rest in the flat state when they are turned over and do not tend to close again as a result of bulging or the like.
- and that the book has approximately the same thickness over the entire width in the
state in which photographs are mounted on its pages.
To this end, according to the invention the method is characterized in that it comprises the following steps: - supplying a straight web of album board,
- making a first perforation at a distance of 1 to 2 cm from a longitudinal edge of the web of board,
- making a second perforation at a distance of 1 to 2 cm from the said first perforation,
- making a means of folding at a small distance from the said second perforation,
- cutting the web of album board into pages,
- gluing a sheet of glassine to each page of album board by means of a narrow strip of adhesive in the region of the second perforation,
- folding the pages of album board in a zigzag manner along the two perforations, and
- combining a predetermined number of pages to form a book and joining these pages together by gluing or by means of punched holes and pins.
[0004] The zigzag parts which have been joined to one another ensure that the book, which in the empty state is considerably thicker at the spine side than at the outer edge, has an essentially uniform thickness over the width in the filled state (with photographs stuck in). As a result of the extra means of folding, the pages can be turned over into the flat state.
[0005] If the photograph album comprises pages which are joined firmly together, endpapers are added to the front and rear end of the book, the pages of the book are glued at the location of the parts which have been folded in the form of a zigzag, the book obtained is clamped and gauze is glued (cold glue) to the spine of the book, and a spine reinforcement, for example crêpe paper, is then applied to the spine of the book by means of adhesive (hotmelt), as are headbands, and the endpapers are glued to a hard cover.
[0006] The said means of folding preferably has to be situated slightly further from the second perforation than the distance between the first and the second perforation. Preferably, the distance between the means of folding and the second perforation is 1.8 to 1.9 cm.
[0007] The means of folding may be formed by scoring a folding line to a depth of at least half the thickness of the board.
[0008] Preferably, the thickness of the board is approx. 0.33 microns and the board is scored to a depth of approx. 0.2 microns.
[0009] An alternative method of making the means of folding which is particularly suitable for a report album consists in cutting a strip out of the web of board and covering the gap formed on both sides with tape. The tapes can consist of paper provided with a layer of adhesive, but they can also be made up of a PVC-based material.
[0010] In order to glue the pages, a cold-gluing method may be used, with the adhesive penetrating 1 to 2 mm between the zigzag parts which lie adjacent to one another in the form of a fan.
[0011] Prior to employing the cold-gluing method, strips of hotmelt adhesive may be applied beforehand to the strips of the zigzag parts, which hotmelt adhesive can be activated by heat for the purpose of achieving a first bond.
[0012] The invention will now be explained in more detail with reference to the figures, in which:
Figure 1 shows a diagrammatic illustration in perspective of the start of a possible method for producing a photograph album.
Figure 2 shows a side view of a pair of pages which have been laid on top of one another during the implementation of the method which is shown in Figure 1.
Figure 3 shows a perspective view of a photograph album which has been produced, a portion of which has been cut away.
Figure 4 shows a diagrammatic illustration in perspective of the start of an alternative method.
Figure 5 shows a side view of two pages which have been laid on top of one another during the production phase depicted in Figure 4.
Figure 6 shows a perspective view of a book which has been produced in accordance with the alternative method.
[0013] Illustrated in Figure 1 is a section of a long web 1 of album board, which has been unwound from a stock roll (not shown), bent back and given a certain tensioning by means of a belt mechanism (not shown). A first perforation 4 is made from the underside by means of a wheel 2 provided with cutting teeth and a mating wheel 3, at a distance of approx. 1.5 cm from a longitudinal edge of the web of board. A second perforation 5 is made at approx. 1.5 cm from the first perforation 4 by means of a wheel 6 provided with cutting teeth and a mating wheel 7, this time from the top side. In addition, a folding line 9 (for example having a depth of 0.2 microns for a board thickness of 0.33 microns) is made from the top side by means of a scoring wheel 8, and a cutting wheel 10 moving in the transverse direction cuts the web of board 1 into sheets 11.
[0014] A sheet 12 of glassine is glued to each sheet 11 by means of a narrow strip of adhesive 13, which is applied on or at a small distance from the inner side of the second perforation 5.
[0016] A predetermined number of pages obtained in this way is combined to form a book, the zigzag elements being positioned on top of one another. The two endpapers 18 are added.
[0017] The pages of the book are glued by a cold-gluing method. The zigzag elements 14 are in this case held in the form of a fan and adhesive which is applied to the spine of the book will, as shown in Figure 3, penetrate between the zigzag elements 14 over a distance of approx. 1 to 2 mm.
[0018] The zigzag elements 14 are clamped on top of one another and textile gauze is arranged on the spine of the book obtained in this manner, and a reinforcement 16, usually consisting of crêpe paper, is then glued on using a hotmelt-adhesive method, as is a so-called textile headband 17 on the top side and the underside.
[0020] The first and second perforations 4 and 5 are also made by the method according to Figures 4 and 6, but instead of scoring the folding line 9, a narrow strip (for example 7 mm wide) is cut out of the board using a double-action cutter 20, as a result of which a gap 21 is formed. This gap is covered at the top and at the bottom by a tape 22. The simplicity of folding (hinging) of each page in the prepared photograph album takes place automatically at the location of the tapes.
[0021] In the same way as in Figure 1, the glassine sheets are mounted and two hotmelt adhesive strips 23, 24 are positioned on the webs of board: one (23) on the top side and one (24) on the underside of the web.
[0022] After having folded the zigzag elements 14, combined the pages 11 to form a book and attached the endpapers 18, the hotmelt adhesive is thermally activated, as a result of which the zigzag elements 14 are bonded together initially. The cold gluing then takes place so as to implement a second adhesive bond.
[0023] Clamping the book, attaching gauze, crêpe paper and headbands and joining to the hard cover by means of the endpapers, take place in the same manner as described in conjunction with Figures 1 - 3. The tapes 22 may consist of paper or PVC.
[0024] If a loose-leafed reporting version is to be made, the glassine 12 is glued on and, in the manner described above, zigzag elements 14 are folded by means of perforations 4 and 5, and a strip is cut out, which is covered by two tapes 22. Finally, punched holes are made by means of a rotating punch. Gluing is thus omitted.
[0025] It is of essential importance that a separate means of folding (either the scored line 9 or the gap 21 covered by tapes 22) is made and that, as result of the zigzag elements 14, the photograph albums produced exhibit approximately the same constant thickness over the entire width in the filled state.
