    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.

    ad 7. one Extrusion crosshead for Injection
    
    Type: Conical entry & injection type
    Application: mono extrusion
    Max finished product diam.: 60mm
    Number of heating zones: 2
    Heating capacity: approx. 2 x 2kW
    Diameter product hole: according to your request
    Extrusion tooling: included for one size
    
    The first extrusion head is injecting the melt into the space in between wires or strands of a steel rope. The steel rope is continuously running through the head.
    
    ad 8. one Extrusion crosshead for outer layer
    
    Type: Cylindric entry type
