(1) riding a horse. Only two iron wire nails are used to connect the pages, because the iron wire is easy to rust and the fastness is poor. Suitable for ordering less than 6 books and periodicals.
(2) paperback. Because the iron wire rusts easily and the pages are loose, it has been used less now. Moreover, the paperback book must occupy a certain binding width, so that the pages can only be "half-opened", and the book is too thick to be easily turned over, which is generally suitable for books and periodicals with less than 400 pages.
(3) sewing thread. Also known as cross-stitch binding, although the book block is relatively strong, there are many stitches in the back of the book, which leads to poor flatness.
(4) wireless binding. Also known as adhesive back binding. Because of the good flatness, a large number of books and periodicals use this binding method at present. However, because there is no corresponding industry standard or national standard for the quality of hot melt adhesive, and the use method is not standardized, the quality of bound books has not reached a satisfactory level.
(5) Binding on the back of the locking glue. Also known as sewing and binding, when binding, each book post is sewn first and then glued, and the back is no longer milled when glued. The books loaded by this binding method are firm and flat, and there are many books using this method at present.
(6) Plastic wire ironing. This is a relatively advanced binding method, which is characterized in that the book posts in the book block are bound twice. The first bonding function is to bond the plastic thread binding foot with the book post paper, so that the pages in the book post can be fixed; The second binding is to bind the book block bound by plastic thread into a book block through wireless binding. The book block bound by this method is very firm, and the influence of bad glue on the binding quality is reduced because there is no need to mill the back and roughen. Plastic wire ironing was introduced to China from Germany (former East Germany) as early as the mid-1970s, but it failed to be popularized and applied in the mainland for various reasons. But in other countries in the world, this binding technology is widely used.
