[0002] As a new type of material between traditional paper and plastic, stone paper is mainly made of calcium carbonate and high molecular polymer, wherein the content of calcium carbonate is about 70-80%, and the content of high molecular polymer is about 20-30%. Stone paper has excellent tensile strength, tear strength and impact strength, and performs well in durability and protection, and is particularly suitable for making products that need to withstand certain external force and are frequently used, such as the cover of a book.

[0003] At present, in the process of making a cover with stone paper, a die-cutting machine is generally used to press lines on the stone paper to press out several creases on the stone paper, so that the stone paper (cover) is easier to fold, thereby meeting the subsequent processing procedure standard and facilitating the use of the book. However, the stone paper itself has too high strength, and after the lines are pressed, the indentations will gradually become shallower, and the folding lines will be difficult to compact. This makes it necessary to rely on manual folding in the subsequent gluing process, not only greatly increasing the production cost, but also significantly reducing the production efficiency, making it difficult to meet the needs of large-scale production. In addition, the quality of manual folding is unstable, and the stone paper is prone to rebound and collide with the gluing equipment, not only causing large loss, but also leading to an increase in the number of defective products. The finally produced book often has an unstraight spine, lacking in aesthetic appearance. In addition, the quality of manual folding is uneven, and the stone paper is prone to rebound. During the gluing process, this is very easy to cause the stone paper to collide with the gluing equipment, thereby causing large loss. The produced book often has an unstraight spine, seriously affecting the aesthetic appearance.
