    Perfect Automatic Barbed Wire Making Machine is simple, sturdy & Robust in design.
    The machine is easy to operate and capable of making barbed wire of two ply and four barbs.
    Barbed Wire Machine is of indigenous porduction,manufactured exclusively out of indigenous
    materials under specialized experienced and skilled management by indian craftsmen.

    OPERATIONS: Perfect barbed wire making machine is assembled with multiple gears and
    lovers so ingenously arranged and accurately timed to perform the multiple function of
    feeding, barbing, twisting, cutting & coiling into a bobbing without the aid of manual labour.
    The operations are so automatic that the operator is to stand by and watch the operations till
    the bobbin is full. Then the machine is stopped and bobbin is replaced & restarted.

    TECHNICAL SPECIFICATIONS : Capable of making G.I. Wires of 3 types.
    1. Main ply two lines of 12G With 4 barbs made 12G wire
    at distance of about 3″ or 75mm apart.
    2.Main ply two lines of 12G with 4 barbes made of 14G wire
    at distance of about 3″ or 75mm apart.
    3.Main ply two lines of 14G with 4 barbes made of 14G wire
    at distance of about 3″ or 75mm apart

    RODUCTION : 500 to 600 Kgs per shift of 8 hours.
    ELECTRIC MOTOR : 5 HP. X 960 rpm
    SPACE REQUIRED : 15 ft. X 12 ft.
    WEIGHT : 1000 Kgs approx.
    ACESSORIES : 4 Nos. Wire Stands.

    INSTALLATION :The installation of the machine is quite simple and easy as that of any
    other machine,care being taken that the stands of the machine is securely bolted to the
    foundation and machine is properly aligned and leveled accurately.



    This film shows a bolted connection where the bolt fails in shear.

    Prior to the connection failing, it is possible to see the deformation in the bolt through the relative movement of the two ends.
