A book with a flap is a book with a cover folded inwards along the opening. Compared with a common paperback book, the flap book has the advantages that the flap book is attractive, flat and durable, and the inner page of the book block and the flap cover can be printed with information such as author introduction and related book bibliography. However, since the cover is produced in a flat state in the conventional glue binding production process, the fore-edge position cannot be cut into a finished product at one time, and the fore-edge position is folded in advance by secondary machine installation or sacrificing part of product quality, the fore-edge position is adhered, and the fore-edge position is cut on line, so that the inner page of the fore-edge position is slightly larger than the cover. All there are more processes in traditional mucilage binding production process, and the control link of product is many in process of production, and the probability of breaking down is great, and product production process has lacked the continuity, and production efficiency is not high, and manual work in the product production process simultaneously, material consumption are very big, and manufacturing cost is great. Certainly, with the increase of the demand, the cementing production equipment is also perfected, newly-produced cementing production line equipment already has a cementing and flap all-in-one machine, but because synchronous interfaces and stations are not reserved in the early stage of a lot of produced equipment, a lot of manufacturers do not carry out secondary upgrading, about 1000 thousands of cementing production lines are estimated, the capital investment required by the new cementing production line is too large, and enterprises are difficult to bear.

The first folding bar 302 is located at the beginning of the sheet 8 entering the folding bar group and is used for folding the two sides of the sheet 8 upwards. As the sheet 8 is fed on the base 1, the shape of the sheet 8 varies according to the cross-sectional shape of the folding bar group. After the two sides of the paper 8 are folded upwards, the paper 8 enters the section of the second folding rod 303, the angle formed by the section of the second folding rod 303 and the base 1 is smaller, and the paper 8 is folded inwards under the force of the second folding rod 303. The third folding bar 304, the pressing-down section 305, and the flattening section 306 serve to flatten the flaps of the sheet 8 completely. The arc-shaped structure can reduce the resistance of the paper 8 entering the turnover rod group section and also prevent the paper 8 from being blocked at the turnover rod group.
