Curing module emits two different wavelengths


US-based Baldwin Technology Com- pany introduced several new technolo- gies at last month’s ICE show in Munich, Germany. One was its XP Quatro


LED-UV curing module, with one head and two frequencies for broader applications. It is designed to cure LED-formulated printing inks and coatings on sheet-fed and web offset printing presses, as well as on larger-format flexo presses and digital print engines. It provides high system


flexibility and reliability, says Baldwin. Hosting two large, high-performance LED-UV arrays, the new module delivers twice the dose of a standard LED solution in a size only slightly larger than Bald- win’s standard compact XP module. The XP Quatro can emit two different


CONTROL Modular engineering for web processing


Baumüller has developed a new template – called Web & Foil – that can be used specifically for web process- ing machines. Its software templates can save developers lots of time. They contain many of the required functions – as well as motion modules and templates – for operations such as alarm handling and prepared visualizations. This means that machine programmers no longer have to worry about the basics during

development – and can focus on process programming. With Web & Foil, Baumüller is


expanding its machine templates to include web processing machines. Web processing machines usually have a virtual master axis, to which other drives of the individual process steps are synchronised. Many automation providers deliver individual libraries for each respective software project. However, the Web &


Foil template contains the necessary libraries as well as general templates for implementation of visualisation or fault management. The developer does not have to set up the basic functions from scratch, as these are selected and parameterised directly. Routine tasks, such as the instancing of motion modules or linking variables with the modules, are no longer necessary. � www.baumueller.com

wavelengths from the same head, which has several advantages. One example is applica-


tions that require simultane- ous powerful curing of deep-layered substrates and surface-curing for inks. This is because longer wavelengths penetrate more deeply, while the shorter waves achieve surface curing. Also, in applications with dual chemistry on one substrate – such as two ink colours that cure better with different frequencies – both can be cured simultaneously. The XP Quatro allows


featured its automated Film Cylinder Cleaner at ICE, which cleans debris from the surface of process cylinders – removing the need for hand-cleaning. By automating this process, film extruders do not need to stop the line to remove debris build-up from the cylinder surface.


“Customers don’t want to


clean these large cylinders by hand,” said Peter Hultberg, chief commercial officer at Baldwin. “Our Film Cylinder Cleaner offers the benefit of reducing the risk of damaging cylinder surfaces.” � www.baldwintech.com

Oben adds a


BOPP line


Oben Holding Group, based in Lima in Peru, has ordered another machine from its regular supplier, Brückner Maschinenbau of Germany. The company has commissioned a second high-speed BOPP line for OPP Film Colombia, based in Barranquilla. The site has an annual produc- tion of 70,500 tonnes of film. The new 10.6m line has a production speed of 625 m/min and an output of 8.8 tonnes/hour. Brückner previously supplied Oben with a 10.4m BOPP line in November 2020 and a 10.5m BOPET line in March 2022. “This highlights Oben’s confidence in our stretch- ing line technology,” said Helmut Huber, COO for sales and project manage- ment at Brückner. � www.brueckner.com
