higher efficiency and shorter downtimes in production. The dosing unit has massage-rollers, capable of handling non-free flowing and fragile materials. Powered by an independent motor and designed for 48 different settings, Spectroflex V is claimed to offer high dosing accuracy for a wide range of materials - even for small dosing quantities. The special design of the oscillating elliptical rollers also extends the service life of the polyurethane dosing hoppers. The unit is equipped with intuitive touch screen control and integration into an existing Motan Controlnet network is possible via an ethernet interface. As an option the conveying control can also be integrated. Motan-Colortronic has also developed a new manually operated coupling station for pneumatic conveying systems, available either as an uncoded version Metroconnect U, or as a coded version Metro- connect C with RFID-technolo- gy. Coded coupling stations can prevent coupling errors and are often necessary if material tracking, validation or certifica- tion is required. An uncoded version can be retro-fitted to a coded version at any time, and older coupling systems can be extended with Metroconnect C, independent of the manufacturer. In machine dedicated conveying systems, every single processing machine is assigned a conveying material feedline. The connection of the pipe to the different material sources occurs via a coupling station, which enables simple and flexible material changes. However, the company says that the manual switching of uncoded couplings is a latent source of error, which can have expensive consequences if the wrong material is conveyed to a machine. With the new coupling system Metro- connect U/C, Motan-Colortronic says that it is offering a flexible concept. The connectors and robust supports on the coupling table of the standard version can be easily and clearly labelled. The lids of the couplings, as well as the lock hooks, are spring assisted, so making handling simpler. Movacolor has developed the MCHybrid, which is claimed to offer important advantages for injection moulding in the packaging industry. The MCHybrid blender is a dosing concept that combines two technologies into one system - batch blending and in-line dosing. The main

materials or regrinds are mixed in an extremely compact gravimetric batch blender. Because the system only blends the main materials, the blend- ing speed is high and therefore the batch blender remains small. The company says that the advan- tages of MCHybrid for the packaging sector include a good mix of the main materials, reduced mixing and cleaning time and 100% dispersion of UV-blocker in the end-product, in combination with the MCBalance. Brabender Technologie is commissioning a
new Technical Centre at its Duisburg facility that will be able to provide more comprehen- sive and complete feeder tests for customers. The centre will offer four independent hygienic testing areas and a feeder filling level facilitates entire process testing. “This gives us entirely new opportu-
nities, in terms of both the quantity and quality of the tests we conduct,” says Chief Executive Officer Horst Vohwinkel. “To date we have suffered from space restrictions and have always only been able to model parts of the process. The new Technical Centre will bring a radical change.” The company says that
simulation of the entire process will now be possible with the new feeder filling level and a 2-tonne overhead crane that can lift
standard packaging such as big bags, silos, drums and sacks. As well as the four full test lines, the Technical Centre also provides space for smaller tests that do not require use of the filling level. In addition, there is a separate area with the hygienic conditions required for food and pharmaceutical applications. Continuous processes are the most common test requested, but batching applications can also be tested on a large and small scale in the Technical Centre, as these are important for producers of high-precision parts.
