| CLAIMS 1. Bookbinding method, in which cold glue is used for gluing the spine (joint), the interior of the spine(joint) of the printed matter(text-blocks)is insulated with a special tape to prevent leakage of the cold glue in the interior, a silicon glue is applied in the holes of the thread seams to prevent inner staining of the printed matter and a paper case is provided and zippers are arranged at the edge of the printed matter(text-blocks). At first, the main body is provided by folding large paper sheets to printing sheets (signatures), and then the outer cover is arranged. During this stage, two 4-sheet end papers are glued, one on the front and one on the back printing sheet. In the mean time, the cover is cut and an incision (1) is made at the center of the cover, where a decorative item (2) is positioned. Then, the covers are jointed to the two end papers. Then, lay-out is made by the procedure of assembling the printing pages. On the left side of the sheets, a perforation and holes are made for inserting the pages in a dossier. Then sewing is effected with a thread and then silicone glue is applied in the holes (3) made by the thread seam on the outside of the spine(joint) so that the strength of the threads is reinforced and the spine(joint) is lined with a special tape (4), which does not allow the cold glue to pass through the holes (3) of the thread seams in the book. Thereafter, cold glue is applied in order to reinforce the book-binding. Also, the spine(joint) (5) is lined with an additional material (fabric) which covers the spine(joint) (5) and a part of the cover, then the spine(joint),(5) is screen-printed, and then a further seam (6) is made on the fabric for further reinforcement. After trimming (i.e. the final cuts are made peripherally of the printed matter), a bookmark (7) is glued on the upper side of the back cover, which is subjected to creasing (i.e. grooves are made which fold easier than cardboard), at various points and on the inner side of the back cover a paper case (8) is glued. Finally, a zipper (9) is arranged on the outer side of the printed matter by sewing. A main advantage of this method is the formation of a printed matter/folder which is closed with the zipper (9), with a soft cover which has a reinforced joint (5) and its interior is protected against glue leakage. 2. Use of the method in forming a book. 3. Use of the method in forming an note book, wherein sections may be provided by positioning separating cardboards between the sheets individual year is printed by screen-printing, or intaglio printing, or silver-printing, and furthermore month indexing may be provided on the right edge of the sheets. 5. Use of the method in forming a notebook. 6. Use of the method in forming a magazine. 7. Use of the method in forming an advertisement leaflet (brochure). |
TAPE AND SILICON GLUE
The invention relates to a method for bookbinding printed matter (text-blocks) that has a paper case (8) internally and a zipper closure (9), which comprises application of a cold glue on the spine (joint) (5), the spine (joint) being reinforced by fabric and sewing (6), application of a silicone glue in the holes (3) of the thread seam, application of a special tape (4) in the interior of the spine (joint) for protection against the cold glue and an incorporated bookmark (7) with creasings.
The various available forms of printed matter (text-blocks) which are produced by applying cold glue on the spine (joint) frequently present the problem that the glue penetrates in the interior of the printed matter (text-blocks) through the holes (3) of the thread seam. This results to page tearing when opening and poor quality. Also, available forms of printed matter (text-blocks) which have internal cases in which pieces of paper (notes, cards, etc.) are inserted do not ensure that the pieces of paper will be retained when inverting the printed matter (text-blocks) upside-down.
By using a special tape (4) in the interior of the spine (joint), which has been glued with cold glue, the pages do not stick together, and the product may be folded due to the thread seam. Also, by applying silicone glue in the holes (3) of the thread seams, the glue is prevented from entering the interior of the printed matter (text- blocks). Finally, by using a zipper (9) on the outer edge of the covers, the items in the inner paper case (8) are retained. Firstly, the main body is folded. Then, the end papers are glued, the end papers being a four-page unit at the front side and a four- page unit at the back side and aiding in the better opening of the product. The covers are then cut (one at the front and one at the back). On the cover an incision (1 ) is made in order to position decorative material (2) (figure 1). Thereafter the covers are connected with the end papers. Then the assembling of the body follows. During this stage, perforation is effected and holes for dossiers are created. Then sewing is effected and silicone glue is applied in the holes (3) on the outside of the spine (joint) (5) (figure 2). Then, the spine(joint) (5) is internally lined with a special tape (4) (figure 3). Then cold glue (5) is applied on the spine (joint) (5) to reinforce the bookbinding, which provides flexibility and strength to the multiple folds of the product without damaging the interior. The spine (joint) (5) is lined with a further material (fabric), screen-printing on the spine (joint) is then 1 performed and a seam (6) is made in order to increase the strength on the spine (joint) (5) during folding of the product and to provide a better appearance (figure 4). The final trimming on the printed matter (text-blocks) is effected and a bookmark (7) is glued, on which creasings have been previously made (figure 5a, 5b). Thereafter, a paper case (8) on the inner side of the back cover (figure 6) is placed. Finally, on the outer side of the front cover and the back cover, respective zippers (9) are sewn (figure 7).
The product may be a book, a notebook having a single section or multiple sections (2, 3 or four), as well as diaries, notebooks, phone indexes etc.
