Riding stapler wonderful invincibility

In a printing product, paper and postage account for about 75% of the total cost, which forced people to change the post-press processing process, thus saving costs. At the same time, ordinary books and magazines are gradually being eliminated by history.

Publishers and directory compiling businesses are also fiercely competing, and they all want to win the market through unique products and services. From plastic cards to fragrant tapes, people want to bind a variety of novelties to books, and even want to print multiple publications at the same time. It can be said that it is the demand of the environment that has driven the change in the role of saddle staplers in the bookbinding field.

Large printing companies like Donnelly, Quad/Graphics, Quebecor and Banta are now facing pressure from all sides. The number of job printing has declined to some extent, but customers have put forward higher requirements for the transfer time, which has forced the printing industry to produce more quickly. At the same time, these printing companies have to solve new technical problems, such as printing on very light paper, which are problems they had not thought about before.

Now, 35 and 27-lb. Offset papers are very common, and the use of super calendar papers is also widespread. The reduction in paper weight means that many book staplers for horse-riding staplers have to be redesigned, while also increasing the transmission speed of the signatures from 5 to 8 copies per second.

Although current super-large-format web presses can produce 64-page signatures, 16-page and 24-page signatures are still the choice of most magazines because publishers want to add as much as possible to magazines. Advertising inserts. Since the insert must be placed in the gap between the signatures, it is easier for the signature with fewer pages to increase the insertion.

Another challenge faced by printing companies is "advertising means." Bill Graushar, manager of post-press R&D at Quad/Graphics, points out: “Advertising has now become an integral part of our industry. And they will never disappear.” Graushar said that the ability to add special elements to the book is crucial of. There are many examples of successful use of these methods, such as: store promotional cards, club cards, fragrance tapes, and e-patches—a card with a plastic film that protects the card from damage. People will also use asymmetrical forms, which will also cause trouble for the production of the signature.

The major high-end postpress equipment makers Martini and Gauss have developed their own high-speed production systems (which can handle 30,000 books per hour), which can reduce the equipment preparation time and are therefore more suitable for use in short editions. Printing market.

Martini has two binding machines that can be used to prepare computers. They are the Tempo 22 and the latest Supra saddle stitcher. The Tempo 22 is a model launched a few years ago and it is the company’s first device to use smart inkjet control throughout the day. Ink jet control is very important for many saddle stitchers (although the number of personalized advertisements using inkjet printing is decreasing).

Combining equipment and inkjet control technology can make the operator's job easier. In this area, Tempo 22 has many advanced features.

Mike Weber, the manager of Fry Communications, said that he bought three Tempo 22s because the binding speed of these devices is very fast and he can keep up with the pace of high-speed printing presses. He pointed out: "The Tempo 22 has a windmill type rotary transmission device that can transfer the signatures to the bookbinding chain, replacing the traditional folding board. This mechanism is more stable, generally without errors and better Handle lighter weight paper.” When a paper jam occurs, people can easily remove the book.

The Tempo 22 has a straight signature transfer device (books) that has more advantages than a vertical book. The vertical book loader loads the signatures at a very large angle and uses the transport chain to send the signatures to the top of the feeder. The flat transmission device can directly transmit horizontal signatures. The straight book bucket is ideally suited for use with stream feeders to ensure smooth binding of lightweight signatures.

Fry purchased Tempos and Martini's Streamfeeders. Weber said that these units allow the binder to operate at 22,000/hr. The Tempo 22s does not require additional tools for job preparation and adjustment - it also allows for automatic setup of JDF files the day the job arrives at the Fry factory. According to Weber, the 304 three-knife optical edger is also capable of rapid setup (using a touch screen), and its book registration can achieve 100% accuracy.

Martini introduced the Supra 30,000/hr saddle stitcher at drupa 2004. Supra can produce long-stapled staples at record-breaking speeds. Supra is a very ideal device. Quad/Graphics is its first customer in the United States.

Gaussian company is not to be outdone, and started to cooperate with Banta Publications recently. Glen DeRosset, the company's binding supervisor, said last month’s R&E binding meeting that Banta chose Goss about a year ago and plans to install a saddle stitcher with a speed of 25,000 to 28,000/hr in 6 months. .

In the process of cooperation, Gauss called Banta's binding technicians and operators for six months of research and development and finally launched a new type of horse-riding stapler, the Pacesetter 2500 SPX-25, based on the Gaussian Pacesetter 1100. The production speed can be close to 28,000 beats/hour.

On Print 05, Gauss also exhibited its redesigned Pacesetter series staplers, flexible book stacks, servo motor-driven feeders, etc., which greatly increase the productivity and processing speed of these devices.

Medium product

Most central printers need a horse-riding stapling system at an affordable price of around 20,000/hr. Martini used its Prima and Bravo-T models to fill this market gap.

Vijuk Equipment has introduced the Purlux Shanghai 321-T saddle stitcher and has tasted its sweetness. The 321-T has a horizontal book stack and the production speed is between 10,000/hr. Both cards and inserts can be fed into the bookbinding line through the horizontal bookcase.

Heidelberg's ST 450 saddle stitcher is a perfectly designed device that gives the user great flexibility without compromising the quality of the binding, and can maintain a production speed of around 14,000 copies per hour. The ST 450 uses a fixed signature conveying device (or book bucket), each of which is an independent paper feeding system and can be placed on either side as required. The ST 450 can process a wide range of substrates from 31/4 x 5 inches to 12 1/2 x 183/4 inches. The signature separating straws have independent vacuuming devices, so that if one fails, the other signatures are not affected by the delivery and opening.

There is a new type of binding head on the market today, which can bind small-size jobs twice. The staple feature of this stapler is the JDF function. It can receive prepress setup data, and once it receives the product size, it can do a lot of work immediately. The collecting device and the paper feeding device can automatically transmit the signature. Staplers, edgers, and stackers can all be automatically moved to the right place. In addition, the system automatically adjusts the length of the feeder based on the thickness of the product.

The Best Graphics Osako Tener series of horse-riding staplers is currently winning a high reputation in the mid-market. This Japanese-designed machine integrates many useful products. Independent signature scanners can make every signature fall into the correct binding chain.

Tener has a monitor that can identify if the binding is normal, a central lubrication system, a wireless remote control system that can turn the machine on and off, a digital caliper (as opposed to the mechanical design), and an error control system.

The ORF-836 rotating bookcase can be easily rotated to the proper angle so that the signature can better enter the gutter in high-speed operation. Each feeder has its own evacuation device so that the air pressure can be adjusted to an appropriate level. ORF-836 also has a high page number and a low page gripper. The Osako OCS-203T Cross Stacker allows the entire system to operate at high speeds.

Stapling in the digital world

Since most of the current continuous web printers can reach a production speed of 500 fpm, people should design a new type of staple system for the market. These new systems should be directly compatible with Océ, Xerox, Nipson, Delphax, or Kodak Versamark digital web printers.

The MBO DIGI Finisher TT 530 combines an MBO folder with a Hohner stapler to fold a digital printed page into four or eight pages.

Then, these signatures will be placed on the saddle of the Hohner stapler. This part of the machine has a lot of vertical books, so that digital printing materials can be combined with digital printing. Barcode scanners guarantee the integrity of pages and signatures.

Standard Horizon's StitchLiner 5500 is another successful model in this market. It is equipped with a three knife edger that can check signatures with barcodes.

The IBIS Smart binding machine is the only digital saddle stitcher that works with digital web printers. It can process proofs from a continuous printer and fold them one by one before stapling. In addition, the Smart bookbinding machine has many unique features, such as the use of cold glue instead of binding, and the transfer of glued signatures to the CP Bourg BB3002 for hot-melt glue binding. The production speed of the Smart binding machine mainly depends on the output speed of the web, but it can reach a maximum of 6,000/hour.

Although Graph Expo is very big, it cannot show all the staplers in front of people. On Demand Machinery did not participate in the show, but the company’s online Super Sewer is a very worthwhile option. This is a device designed for print-on-demand publications (minimum and maximum machine sizes of 6 x 8 inches and 11 x 14 inches, respectively). The Super Sewer uses Back Tack's patented technology to guarantee the smoothness of the edges of the books through the use of sewing threads. It is understood that the maximum production speed of this device is 600 copies per hour.
