According to the processing method of cover, there are book covers with spine grooves and without spine grooves. The back of the book block can be processed into hard back, concave back, soft back and so on. , beautiful and durable.
The binding process of hardcover books is as follows: making the book block → making the book shell → making the first part of the book block with the book shell is the same as the binding process of paperback books, including cutting, folding, page matching, sewing and book cutting. After completing the above work, the unique processing technology of hardcover book block will be carried out. The book block is a round back with a ridge. On the basis of paperback book block, the hardcover book block can be processed by flattening, gluing, drying, cutting, rounding, ridging, gluing, gluing gauze, gluing again, sticking plug cloth, sticking spine paper and drying. The book block is in the form of a square back without ridges, and it does not need a circle. If the book block is in the form of a round back without ridges, there is no need to ridge it.
1. flatten
Flattening is carried out on a special book press, which makes the book block firm and flat and improves the binding quality of books.
Brush glue
Brush glue manually or mechanically, so that the book block reaches the basic shape, and the signatures will not move each other in the next process.
cut
Cut the basically dry book block into a light book block with glue.
Step 4: Circle
The process of machining the back of the spine into an arc by manual or mechanical means is called rounding. After rounding, the stickers of the whole book can be staggered, which is convenient for reading and improves the firmness of the book block.
ridge
The book block is clamped with a splint manually or mechanically, and dents are pressed on the front and back sides of the book block, near the edge of the connecting line between the spine and the ring lining, so that the spine slightly protrudes outward, which is called ridging, to prevent the book block from becoming round and deformed.
6. Spine processing
Processing contents include: glue brushing, bookmark tape pasting, gauze pasting, plug cloth pasting and spine paper pasting.
Sticking gauze can increase the connection strength of the book block and the connection strength between the book block and the book shell.
Sticking cloth on the upper and lower ends of the back of the book block makes the books closely connected, which not only increases the firmness of book binding, but also makes the books beautiful.
The spine paper must be stuck in the middle of the spine of the book block, without wrinkling or foaming. This is the cover of a hardcover book. The material of the book cover should have certain strength, wear resistance and decorative effect.
A bookcase made by connecting the front cover, back cover and back cover with a whole piece of cloth is called a single bookcase. The front cover and the back cover are made of the same fabric, and the bookcase with the back cover made of another fabric is called the ingredient bookcase.
When making a book case, the cover material is cut and glued according to the specified size, and then the cardboard sealed before and after is pressed and positioned (called casing), and the four corners are wrapped and flattened to complete the book case. Because of the low efficiency of manual operation, bookcases are now made by machinery.
The book shell is finished, and the title and design are printed on the front cover, back cover and back cover. In order to adapt to the curved back of the book, the book cover needs to be rounded after finishing. The process of connecting the book cover and the book block is called the book cover, also called the cover.
The method of sticking the book cover is as follows: firstly, glue is applied to the lining page of the book block, and it is placed on the book cover according to a certain position, so that one side of the book block and the book cover are firmly bonded, and then the other side of the book block is evenly stuck on the book cover according to this method, so that the whole book block and the book cover are firmly bonded. Finally, press a groove on the front and back edges of the book with a line pressing ridger to dry the book and make it more flat and stereotyped. If there is a protective seal, it can be wrapped and delivered from the factory.
The binding process of hardcover books is complicated. Manual operation has many operators and low efficiency. At present, the hardcover linkage machine can automatically complete the binding process of hardcover books, such as book block supply, book block flattening, glue brushing and drying, book block pressing, three-sided cutting, book block rounding and ridging, book block brushing with gauze, paper jam and cloth stuffing, book case, groove pressing and book publishing.
The domestic JZX-0 1 hardcover book binding automatic production line consists of a book block feeder, a book block flattening machine, a glue brushing dryer, a book block compactor, a book block stacker, a three-sided cutting machine, a rounding ridger, a conveying reversing machine, a book block pasting machine, a book block capping machine, a groove pressing machine and other single machines arranged in the above order.
Luxury clothes. Luxury clothing is also called artistic clothing. Luxury is similar to hardcover, but the materials are more advanced, the appearance is more gorgeous and the artistic sense is stronger than hardcover. Generally used for high-grade picture books and books with high preservation value. Mainly by manual operation.
