Folding machine to adapt to market demand and introduce new (1)

First, folding is an indispensable step in high-quality printing. Referring to post-press processing, people think of more lamination, bronzing, embossing, punching, and other post-press processes, often neglecting post-processing such as folding and cutting. Essential steps. An old printer who had been printing for twenty or thirty years once said to me, "Fold it, simply, and use a bamboo plate to do it."
For many years, folding was done in this simple way. Until the industrial revolution of the 19th century, machine folding occurred, mainly with folding knives. In 1920 it was only invented the fence-folding. In the development of publishing post-press processing equipment, Germany's Tal company has a significant role.
Stahl was founded in 1949. In 1950, the first folding machine was successfully manufactured by one of its founders, Kurt and Starr. Since its establishment, the company has achieved brilliant success in the printing industry. To date, more than 100,000 Stahl folding machines have been used throughout the world.
1999 makeup. Heidelberg acquired Sterling for US$56 million. Since then, folding processing has become an important part of printing production, and it has been integrated into Heidelberg's production processes. This has enabled Heidelberg's dream of integration before printing, printing and postpress to become a reality. So what exactly is Starr's spread of the essentials? Essentially, folding machines use mechanical work to overcome the inherent tension of the paper at the first place to achieve precise folding of the paper. There are only two basic folding methods: vertical folds and song credits. However, there are hundreds of folding orders, and due to the differences in paper quality, paper thickness, weight, size, and so on, the folding methods and sequences used are not the same. Many people in Heidelberg who have been engaged in folding machines for many years without a layer are feeling that “folding is too complicated”.
Second, Stahl folding machine's main product series At present, the Stahl family of the two latest flagship product is TD series folding machine and KD series of mixed folding machine. "T" refers to a fence-type folding, and "K" refers to a combination of a folding knife and a fence. The “D” of “KD” and “TD” refers to the digital control system, which is the Starr DCT2000 control system. Depending on the width of the paper, the KD and TD series of folding machines are available in three different models: 66, 78 and 94. Since the debut of the drupa exhibition in 1995, both folding machines have achieved great success.
KD and TD folding machines have excellent performance and high efficiency. Its folding speed reaches a record-breaking 230 meters per minute, and even if the paper used for folding is recycled five times, it does not affect its speed. And 25 years ago, the fastest folding machine was only able to fold 120 meters per minute. At present, home-made folding machines can reach 200 meters per minute at the fastest.
The high speed of Stahl's folding machine does not affect its folding quality at all. First-class quality and continuous technological innovation are the secrets of Stahl's repeated successes for half a century. The Stahl fold can do so thanks to the perfect automation of its electromechanical devices.
In the electronic part, Stahl's folding machine adopts DCT2000 digital control system. This technology has long been applied to the manufacture of advanced technologies for automobiles and aircraft. It is the first time that it has been used in the post-press processing industry.
The DCT2000 is like the soul of a machine, monitoring the entire process of passing from the fly to the delivery table. It consists of a central-inside digital control system located at Feida and an independent control system located at each folding group and its delivery section. The transmission of information between the central control system and the control systems of the various parts is carried out by an anti-interference data line (called Starr CAN). This "information high-speed company" may guarantee that information exchange is not restricted.
With the DCT2000 software, the folding machine can automatically measure the length and number of sheets, automatically set the length of suction and the distance of the sheets, and store the job. It is said that Stahl will also implement display screen operation soon. This allows the user to set the folding directly on the screen and select the type of folding.
In the mechanical part, Stahl adopts a unified block design that not only facilitates cleaning and maintenance, but also makes the standard configuration flexible and compact, and provides the possibility of configuring and producing various special equipment. In recent years, from the KD and TD basic models (TOPLINE) and spring-specific extensions to the latest model (MEGALINE), a series of technical improvements have been made from the basic tool for folding, the grid to each gear.
