What is folding machine

The folding machine is mainly used for folding paper with different sizes and thicknesses within the design range, and is suitable for large quantities of folding pages of rapid printing centers, production enterprises, official documents, and business letters.

folding machine (folding machine; folder is a modern printing equipment produced along with the modern printing industry. Modern printing plants usually contain three processing processes of pre-press, printing and post-press, and the main bearing media is paper. Due to the rise of packaging and printing, other material media, such as plastic, fabric, leather and metal surface, are also on the rise, but the main carrier is still paper. Printing industry processing is usually divided into book and newspaper processing and packaging processing; The folding machine is mainly used for folding paper of different sizes and thicknesses within the design range, and is suitable for large quantities of folding pages of rapid printing centers, production enterprises, official documents, and business letters.

The domestic high-speed folding machine is mainly composed of paper separation system, paper feeding system, bending parallel folding system, vertical folding knife folding system, frame, transmission system, electrical control system and receiving system. Although our ancestors invented printing a long time ago, the level of printing technology in China today is relatively backward, and domestic advanced folding machines only reached the international advanced level in the 1990s [1].

At present, the order of printing enterprises appears the development trend of multi-variety, small batch and short delivery time. This trend will boot the preparation time and machine frequently set time in the proportion of total production time to become higher and higher, while the actual production time is relatively reduced, in the fierce market competition, which means that post-press processing enterprises must produce more products in a shorter time, in order to obtain more profits. Therefore, the optimization of the production process and the integration of operating procedures make every product more reliable, and put new and higher requirements on the manufacturers of post-press equipment.

At present, the latest high-speed folding machine has been humanized operation interface, the adjustment of all folding actions can be digitized and automated, and more advanced folding machines can also be networked, integrated into the global unified command interface for the entire automatic control operation of the printing plant, and can be remote control and centralized control. High-speed automatic folding machine is divided into folding knife, folding fence, folding roller, paper feed table and receiving table, as well as the control part and other main parts, due to the needs of modern printing high-speed uninterrupted operation, for the use of raw materials anti-wear, hardness, surface treatment and processing accuracy have very high requirements. At present, the high-end products of China’s high-speed automatic folding machine are still mainly dependent on imports, but with the improvement of the level of China’s processing industry and the continuous entry of foreign factories into China, the level of China’s domestic enterprises is also rapidly improving.
