The Cold feed Extruders have been developed for processing cold rubber compound. Since these machines,
in addition to extruding profiles also plasticize rubber, they differ from hot feed extruders.They have longer screws, heavier gear boxes and higher drive power. According to present stage of
development cold feed extruders can be used for extruding almost all rubber compounds which are
processable on hot feed extruders. Feeding is normally in the form of strips or pellets. Machines
with longer screw diameters are often fed directly with wig-wag stored slabs.
