press release

Cologne, Germany – At ProSweets 2016, Bosch Packaging Technology, a leading supplier of processing and packaging solutions, is launching its upgraded WRF 600 Flex roller former for multilayer bars. The latest solution from Bosch enables customers to produce multilayer bars, such as those consisting of nougat topped with a layer of caramel, on the same production process. Thanks to its patented flexible working width it is designed to minimize or eliminate the trim when processing masses for cereal, candy, protein and fruit bars. Bosch's WRF 600 Flex enables width changes without production stoppages, maximizing uptime and output. No other machine of this kind on the market offers this capability.

Less waste, more bar
The WRF 600 Flex features a smooth slab former with a flexible working width that allows for easy, step-less and tool-free adjustments for the precise cutting of multilayer bar products in different sizes. As a result, less product mass is wasted, helping to decrease production costs and contributing to a higher return on investment (ROI). To accommodate slabs of different widths, operators simply make a manual adjustment to the machine during production – completely eliminating downtime. Removing the need for machine stoppages also reduces waste, maximizing product usage and enhancing productivity. The WRF 600 Flex gently forms the mass slab without applying any pressure, preventing product breakage. The working width ranges between 400 and 1500 millimeters. As a standard feature, the slab thickness can be continuously adjusted between 5 and 30 millimeters.

With its hygienic design, the WRF 600 Flex allows manufacturers to meet the most stringent hygiene requirements and offers access from all sides, resulting in easy and tool-less cleaning. “Today's manufacturers need technologies that can efficiently handle delicate products and decrease waste more than ever,” says Frank Jansen, product manager, Bosch Packaging Technology. “The WRF 600 Flex is well positioned to meet these demands thanks to its flexibility and operator-friendly features.”

In addition to its bar processing technology, Bosch also provides primary and secondary packaging solutions for bars. Designed for simple integration with existing Bosch technology, manufacturers are able to partner with a single-source solution provider for their entire bar production line. Standardized interfaces allow for the balanced speed of all line components to eliminate bottlenecks, minimize downtime and optimize production flow, facilitating high Overall Equipment Effectiveness (OEE).

Smart Service
For its customers, Bosch is also offering a Confectionery Service App for smartphones, tablets and PCs as part of an enhanced service package, complementing its confectionery and food technologies. The app can be combined with the existing Bosch “E-Portal”, which contains customized – as well as machine-specific – spare parts data, allowing for the transparent flow of information and a simplified ordering process. The app supports easy and immediate contact with Bosch's technical support team and ensures access to repair instructions.

The WRF 600 Flex for multilayer bars, along with other technologies from Bosch, will be on display in Hall 10.1, booth C10 at ProSweets 2016 in Cologne, Germany, 31 January to 3 February 2016.
