Multiplex Extruders

Extruders for multi-structure profiles play an extremely important role in improving tire quality. A tire consists of a tread, sidewalls and bead section. The respective components are formed from a number of rubber compounds with properties required for specific aspects of tire performance. With multiplex extruders, the rubber profile components are extrusion molded as a single air-free, multi-layer/compound unit under high pressure. Nakata makes cold feed extruders and pin type extruders up to 300 mm. These machines are arranged in piggyback type of 2, 3,4 and 5 layers, and in opposed type with 2 and 3 layers. Multi-layer extrusion heads have also been developed and adapted to these units. These have also been incorporated into production lines with good results.
