Martini's SigmaLine is a modular post-processing system that produces books on demand. The user can choose a complete production line, that is, the entire inline processing system including printing, folding, saddle stitching, book cutting, collating and binding; or part of the configuration, such as just a wireless binding machine, cooling tower And high-speed rotary printing machine with three-sided book cutter. SigmaLine's design concept is used to produce a large number of on-demand books without compromising quality. Andy Fetherman is the head of Martini ’s on-demand solutions department. He said: "We bring the highest commercial quality post-press surface finishing to the digital printing market. Our target customers are those requiring higher-end production systems Customers who supplement the production of offset books, as well as those digital printers who want to compete with offset printing companies with the highest quality. " When it comes to configuring different SigmaLine components, buyers will have a variety of options, which is a bit like ordering through a recipe. Users can choose the rotation equipment of Delphax, Océ, Nipson, Xerox and IBM (currently discussing cooperation matters with Kodak Wansheng). These equipment can be matched with different configurations of Martini SigmaLine. The fully automated SigmaLine system has three key components, one is a SigmaBinder wireless perfect binding machine with a speed of 1000 books / hour and variable size, one is a SigmaTower cooling tower that cools books and dries the adhesive, and the other is a speed of 1,500 This / hour, and variable size SigmaTrimmer three-sided knife-cutting machine. At present, many partners are involved in the integration of the production line, making the entire production line more complete and smooth, such as the unwinder, roll paper cutter and collating machine of Hunkeler and Lasermax Roll Systems; you can also install the Palimides book stacker MBO folding machine and so on. Fetherman pointed out: "SigmaLine has a large number of built-in modules. You can buy a near-line version of SigmaBinder, and then install it in SigmaTrimmer, and then connect the remaining components of SigmaLine. A customer with multiple Xerox DP 1050 or Océ 7650 can now choose SigmaBinder for near-line configuration. Fetherman said: "They want to equip multiple printing lines with a binding device, so they can install SigmaBinder near the line." Measuring workstation increases flexibility SigmaBinder's measurement workstation has played a key role in the overall performance and flexibility of the system. For a special job, the binding device is installed in the near-line configuration. The operator must turn the book block down in the measurement workstation and activate the sensor. Fetherman explained: "The measuring station squeezes the book block after receiving it, and then uses the laser to measure the thickness, length and width of the book block after squeezing. Then use these three data to set all the length and width through the SigmaBinder, And thickness variables. You can make the process from one book to the next book seamless, regardless of size. " The measurement system can be used online, acting as an inspection workstation. Fetherman said: "Here you can verify whether the cover of the book fits the book stack and whether the size given by the previous process equipment is correct. If the cover does not match or the size is incorrect, then the book stack or cover will be pushed out. Then you can find Where is the fault. " Even if the printing machine is shut down for maintenance, the user can continue the book from another production line. Fetherman said: "We know that the uptime of the machine must be maximized so that users can exceed the ROI requirements. We also know that there is some controversy between the connection and the near-line. But offline means that there is no connection with other devices. This is something we disagree with. Our measurement workstation allows SigmaBinder to operate in near-line configurations, even in connection configurations. What's next Martini has been improving the device since it first showed SigmaLine at Drupa 2004. Fetherman said: "We are making a controllable product, which will be completed in 2006 and will be fully promoted." The new improvement includes a drum with a continuous cover, which allows the operator to make the book stack and cover before entering SigmaBinder match. Fetherman said that Martini is currently working to make the device have more cover intelligence and technology, which will further improve SigmaLine's production efficiency. The complete SigmaLine has been installed for the first time in the United States, and it is capable of wireless bookbinding and saddle stitching of books.

Figure 2: SigmaLine is a modular system, part of the configuration includes SigmaBinder (formerly Amiago Digital), which is a wireless binding machine with a variable size of up to 1000 volumes / hour; Sigma Tower is used to cool and dry the adhesive And Sigma three-sided book cutter. For books of various sizes and thicknesses, the preparation time before cutting is zero.
