ELASTOMER ROLL-EX® FINE MESH RUBBER STRAINING It has been proven that the quality of rubber compounds can be improved significantly by fine mesh straining. The Davis-Standard and Uth roll-ex® gear extruder with TRF (two-roll feeder) technology provides an economical and efficient processing option. The roll-ex is engineered for straining applications of accelerated compounds because of its non-aggressive material treatment. Modular in design, this extruder can also be used in a single step together with the mixing process for a cost-effective solution. At A Glance • wo-roll feeder (TRF) integrates processing part and strainer head into a compact T two-stage unit, which is linked to the fine mesh straining of warm material. • ow temperature increase when using fine mesh screens and high pressure up L to 500 bar because of gear pump characteristic and TRF feeding combination. • xcellent feeding of warm rubber strips from the two-roll mill by the E independently driven and controlled TRF. • mall footprint for simple integration into existing mixing lines without S additional operators. www.davis-standard.com

ROLL-EX® FINE MESH RUBBER STRAINING cont. ROLL-EX® STRAINER ADVANTAGES The roll-ex® TRF is the result of thoughtful and skilled engineering, which has resulted in a process-orientated design, a high level of functionality, economic advantages, and operational ease. • Due to automatic control, the roll-ex can be controlled by mixing line operators so that no additional manpower • The hydraulically-operated strainer heads with a unique mechanical design enable fast screen changes, eliminating the need for automatic screen changers. • Rotor bearings are lubricated by the compound.
