Abstract
The invention relates to an extruder for the preparation of rubber mixtures for elastomeric products and comprises a cylinder, an endless screw rotatably mounted in the cylinder for uptake transport and homogenization of the rubber mixture, and an extrusion tool; wherein the endless screw is configured with zones of multiple treads in dependence of varying helix angle and depth of thread so that the rubber mixture transported through the zones undergoes a temperature increase through heat dissipation to such an extent that the temperature of the extrudate approaches the vulcanization temperature thereof.
