[0042] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further described with reference to specific embodiments.
[0043] See figure 1 , A process of repairing ancient books of the Song and Yuan Dynasties by using the inner folding thread-bound and back-bound framing technology. Taking the ancient books modified into the thread-bound style as an example, it includes the following steps:
[0044] A, such as figure 1 As shown, cut and remove the nail lines at the book brain 1, book back 2, book corner 3 of the ancient books of the Song and Yuan Dynasties, and remove the paper twist nails that fixed the leaf;
[0045] B. See figure 2 , Spread out the leaf of the book, with the text side facing down, and use the same texture and color as the holes left by the original thread on both sides of the book (including holes 4 when nailing threads and holes 5 when paper twisting nails) Make up the paper; after the glue (the glue is special glue for ancient book restoration) is dry, fold the side of the leaf with text in half, and the A and B sides without text are outside, such as image 3 Shown
[0046] C. Cut two pieces of paper with a length equal to the height of the leaf and a width of 3.5-6.5 cm (in this embodiment, the width is 5 cm); see Figure 4 , Place the 1.5 cm-3.5 cm width part of the first note C (ie Figure 4 The shaded part of the first paper strip C in this embodiment is 2 cm wide.) is pasted on the side of the book page A near the fold line. The remaining part of this paper is on the outside of the book page A to facilitate subsequent Threaded, such as Figure 5 Shown; see Image 6 , Paste the second piece of paper D on side B of the book page in the same way;
[0047] D. Cut the third piece of paper E whose length is the same as the height of the leaf, and the width is 3-3.5 cm. Insert the third piece of paper E into the gap between the first piece of paper C and the second piece of paper D , Until it touches the leaf fold line; the choice of paper thickness is best to meet: the sum of the thickness of the first paper strip C, the second paper strip D, and the third paper strip E is equal to the sum of the thickness of the book pages after folding; Only one page in the Song and Yuan books was restored;
[0048] E. Repair the remaining pages in accordance with steps B, C, and D;
[0049] F. Arrange all the pages of the book according to the butterfly form and in order of page numbers, and glue the front parts of the adjacent pages of the adjacent book pages together. The width of the bonded part is 1.5-5 mm (in this embodiment, the width is 2 mm ). Such as Figure 7 As shown, the grid shadow part of the A side of the first page and the grid shadow part of the B side of the second page are glued together. Glue side A of the second page and side B of the third page in turn; glue side A of the third page and side B of the fourth page until all the pages are glued together. At this time, the whole book has begun to take shape, such as Figure 8 Shown. When gluing, all the outer edges must fit neatly, except for the back part of the book, and no misalignment is allowed.
[0050] G. The first strip of paper C, the part of the second strip of paper D on the outside of the page, and the third strip of paper E of the book page are used as the book brain, which is bound by stitching in the form of thread binding; see again Figure 8 , The binding line of the thread binding is the dividing line 6 between the first paper strip C and the pasted part and the un pasted part of the book page.
[0051] H. In step F, when gluing, except for the back part of the book, all the outer edges must be neatly fit, and no misalignment is allowed. So, just trim the back of the book neatly. Put the book in the trimmer and put Figure 8 The book back 7 shown in is cut to about 1 cm to achieve a neat and smooth cut.
[0052] I. Install the protective seal, take a piece of thick paper, the length is the sum of the width of the front, back, and back of the book, and the height is the same as the height of the book; according to the modern paperback style, the thick paper is glued to the front, back and back of the book ,Such as Picture 9 Shown.
[0053] After the above eight steps, an ancient book from Song and Yuan that was rebuilt in the Ming and Qing Dynasties or modern times, and originally in a butterfly costume, has been restored to its basic original appearance while being innovative.
[0054] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the industry should understand that the present invention is not limited by the above-mentioned embodiments. The above-mentioned embodiments and the specification describe only the principles of the present invention. The present invention may have various forms without departing from the spirit and scope of the present invention. Changes and improvements, these changes and improvements fall within the scope of the claimed invention. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
