New: Thanks to Asir 3 Even More Reliable and Efficient
Thursday 24. January 2008 - drupa 2008 is already on the radar! Around a half year before this monumental event for the graphics industry, Müller Martini Buchtechnologie GmbH presented its Ventura book sewing machine, now with Asir 3 control system, to visitors at the in-house exhibition in Bad Mergentheim, Germany.
Integration of this control system, which is familiar from the Müller Martini saddle stitcher and rotary gatherer, with the world-renowned Ventura has further increased the machines production reliability.
The Asir-3 system was presented as an important innovation for the Ventura at the in-house exhibition. It simultaneously checks the proper sequence of signatures and the section opening with a sensor. This can be done with image comparison mode or barcode recognition according to the settings.
More and more book binders worldwide are producing first-class book blocks with the Ventura book sewing machine from Müller Martini Buchtechnologie and theyre amazed at its reliability. A variety of control devices ensures the accustomed high reliability with which the Ventura delivers the best quality layer after layer. For the first time, Müller Martini is offering the Ventura book sewing machine with the tried and true Asir 3 control system.It tests for the correct sequence of the sections and that they open in the right place. This can be done either in image comparison mode or through barcode recognition.
Asir 3: Barcode or Image Comparison – The Customer has the Option
The sensor in the Ventura consists of a “smart” camera that recognizes and determines whether sections have been fed properly or not. The sensor is installed such that it checks the sheets from inside. This mechanism patented by Müller Martini is able to recognize sections which do not enter in the right sequence as well as those that were not properly opened. In the Image Comparison Mode, the Asir-3 sensor prepares and tests four exposures per section as they run through. The range within which the exposures are made is variable, and the operator can adjust it depending on the product. One can alternately use barcode recognition for clear identification of the signatures. In this case, the sensor scans the barcode applied to the head edge. With the barcode, one can ensure with one-hundred-percent certainty that the sheets that have not been fed properly are recognized and diverted. Müller Martini offers users a program for producing barcodes, which is contained in all standard prepress industry software programs.
Efficient Sheet Feeding in Piles
In order to feed sections into the feeder of the Ventura book sewing machine efficiently and reliably, Müller Martini Buchtechnologie offers an automatic pile hopper. The book binder places the loose book blocks in piles of up to 220 mm high on a powered roller table conveyer where they are buffered. For A5 formats, for example, the belt can hold seven piles, for A6 formats ten piles. The machine is timed to transfer the first pile to the feeding fork, which automatically and gently places it in the hopper feeder.
Flexible Working and Secure Feeding
This stack feeder with buffer allows the operator to work flexibly and efficiently. Even while the machine is operating at high speeds, it is capable of feeding sufficient sections which ensures full utilization of the machine and therefore also high productivity. Even though the operator can put on a large quantity of sections, the pile remains low on the feeder. This ensures that coated papers and those with lower poundage feed through more reliably.
The proven Ventura book sewing machine with Asir 3 will be one of the myriad highlights that Müller Martini will present to visitors from May 29-June 11, 2008 at its drupa stand B38 in Hall 14 in Düsseldorf.
