By the application of microprocessors and handling instruments (robots) new ways are opened for full automation of mixing-lines. The electronic control systems to complete compounding streets, which are already frequently in use nowadays, make it possible to reduce tremendously the manual activities by modern conveying and weighing systems for free-flowing resp. fluid bulk components. Complete small charges of components can be weighed automatically and combined over several weighing-machines, which are connected by transport systems. The use of modern handing instruments opens ways for taking up and metering of rubber automatically in its manifold forms of delivery.
