A folding and creasing machine is primarily used for creasing and folding paper to create covers for various books and printed materials. It typically consists of a series of rollers, folding plates, and blades, allowing quick and precise creasing and folding operations on paper sheets. The machine achieves high levels of automation and production efficiency, enabling rapid production of numerous covers while ensuring precise creasing and folding for each one.

The process principles involve several key steps：

*Feeding of Books：A rapid continuous feeding mechanism pushes books, ensuring consistent spacing between them.

*Cutting：Trimming excess paper to ensure uniform and neat appearance. The cutting device utilizes a combination of blades and cushioning pads, providing excellent flatness after cutting and extending the lifespan of the blades.

*Creasing：Creating folds on the book covers and backs, stabilizing them for subsequent folding operations and preventing damage to the books.

*Folding：Simultaneous downward pressure from two sets of folding mechanisms on the left and right sides completes the folding action of the book covers.

*Output：Books with folded covers are neatly pushed out in a centralized manner for further processing, packaging, or distribution.

The entire process is controlled and coordinated by the machine's computer control system, ensuring precision, consistency, and high efficiency in production applications.
