New requirements in the tire industry, the demand for sustainable and reliable processes, the consistent reduction of the scrap rate, new specifications: All these aspects are covered by the new generation of roll-ex® machines. These machines are used in the different areas of tire manufacturing, for example, in the rework area (based on the TRP technology for the economical and gently reworking of material generated in tire production), in the mixing line for the final compound and master batch, complete offline straining cells and in the extrusion line.
UTH’s proven roll-ex® extrusion system has become the benchmark on the international market for fine mesh straining solutions: The roll-ex® gear pump ensures particularly gentle processing of the material and fast compound changes. With throughputs of up to 10,000 kg/h the gear pump extruder and strainer solutions are optimally developed for the cost-effective performance of mixing lines in the tire industry. Inline straining, in particular, offers advantages in tire production, which are shown, for example, when straining masterbatch stages or final batch. The modular combination of the patented gear pump with a two-roll feeder (TRF) or a conical double-screw extruder (DSE) allows integration in almost all mixing lines.
Apart from these applications, there is a market demand for continuous strip-making solutions with optional straining capability. To meet these requirements a compact straining cell consisting of a gear pump with a single screw extruder as well a cooling line and stacking unit is used.
