    TECHNICAL SPECIFICATION
    The purpose of the Inline Extrusion is the filling of gaps inside of steel ropes avoiding dirt to enter the rope causing damage and wear.
    One extrusion head is placed before the stranding die holder. A second extrusion head is placed behind the stranding die holder. The first extrusion head is injecting the melt in between the strands during closing.
    The entire unit is positioned on rails and can be moved inside the stranding line when required or outside the stranding line when not used.
