Some books don‘t have a cover that is just flush with the inner core, but instead have an extra section folded inward, which is actually a flap.

What is flap ?
In paperback book binding, there is a special type of binding called flap, also known as a fold.
To do the book, often the front cover and back cover of the front edge are larger than the core of the front edge, when we will be wide out of the cover along the core of the front edge of the cut edge folded inward, forming a decorative folded part of the so-called flap binding.
What is the role of the flap?
The main roles of flap:
(1) To organize relevant information. For example, author‘s or translator‘s introduction, bibliography of similar books, pictures related to the book, and the cover description text, etc. Of course, there are also some lekou is blank.
(2) Protect the core of the book. As the flap is the excess part of the folded inward, which will make the front edge of the cover is slightly larger than the inner core, which can play a protective role for the core, more conducive to the transportation and preservation.
(3) Prevent curling. After the inner fold, it is equal to double the thickness of the front cover, which can effectively prevent the front cover and back cover from curling.
(4) Beautiful atmosphere. Some Lekou is obviously blank, but still have to do, in addition to protect the books, in fact, also for the purpose of decoration, do the flap book, the quality of people will immediately give the feeling of rising a grade.
(5) bookmark utility. For the book is not particularly thick, sometimes the mouth can be used as a bookmark, not only convenient, but also can quickly find the reading position.
The use of flap?
Since flap has a lot of role, then why usually most of the books are not used in this way of binding? Apparently it is mainly because of the cost. Not to mention the craftsmanship, but in terms of materials, the front and back covers of a lekkou are much larger than those of a non-lekkou.
Therefore, the application of flap is relatively small, commonly used in some hardcover books. In addition, there are some literary books, such as novels, poetry collections, works of art and so on. The former is for better preservation, the latter is because of more flipping, and easy to organize the author‘s information.
