Abstract

Process for producing from a rubber mixture blanks for finished parts in the rubber industry is composed of an extruder having a cylinder and a screw rotatable in the cylinder to plasticize a rubber mixture fed into the cylinder, an extrusion head and a gear pump between the extruder and the extrusion head for producing extrusion pressure and forcing the mixture through the extrusion head at a predetermined rate per unit time to form a uniform strand of predetermined shape which is cut into uniform lengths.
