ABSTRACT:
A method and apparatus for continuously producing reinforced profile belts of extruded material provided with a stretch resistant insert strip 6, wherein the extruded material stream 3 passes between two circulating endless loop halves 1, 2 of a divided former which converge along a portion of their lengths to form a closed former or pressure molding segment or run. The former segment is straight and the insert strip coated by the extruded material is pulled through it under tension. The insert strip inside the finished and hardened belt is encased on all sides and lies in the belt's central or neutral zone after leaving the apparatus.
