Product catalog summary
Overview of ROLL-EX® Extrusion System
The ROLL-EX® extrusion system, developed by Uth GmbH and distributed by Davis-Standard, is designed for high-volume fine mesh rubber straining with a focus on high output stability. Its modular and compact design makes it suitable for mill room mixing or integration within a mixing line. The system is capable of processing between 0.45 to 6 metric tons per hour, reducing scrap, and producing high-quality rubber with minimal defects.
Key Features
  • Compact design with up to 70% energy savings.
  • Stable temperature levels under high pressure.
  • Improved quality for specialty applications.
  • Simplified maintenance and faster material changeover.
  • High degree of amortization.
System Advantages
The ROLL-EX® system operates on the gear pump principle, using two interlocking rotors to generate extrusion pressure. This design ensures gentle material processing with a short retention time and constant temperature maintenance at pressures up to 500 bar. The system's volumetric conveying process ensures uniform pressure for precise extrudate output, reducing waste and energy demand by up to 70% compared to single screw extruders.
Design Benefits
  • Two-roll feeder system eliminates the need for a screw extruder, reducing shear and extrudate temperature.
  • Allows high output rates with accelerated compound formulations.
  • Minimal material dwell time and low temperature increase.
  • Hydraulic system provides easy access to major components.
  • Straining rubber in a warm state offers energy and cost savings.

ROLL-EX® EXTRUSION SYSTEM cont. SYSTEM ADVANTAGES Based on the gear pump principle, the roll-ex® system generates extrusion pressure by two interlocking rotors. Material is gently processed due to a short retention time within the unit and a constant temperature is maintained at pressures up to 500 bar. Due to the volumetric conveying process, the pressure is uniform to provide precise extrudate output. The minimal volume of the system reduces the amount of waste when changing over compounds, and limits energy demand which is up to 70 percent less when compared to that of a single screw extruder....
