The South Fence Machinery Ltd Fixed Knot Machines have been developed from the Company’s extensive experience of more than 75 years in the manufacture of wire products and machinery specifically designed and produced for the manufacture of rural wire fence products.
It is the vast experience gained over the years that has enabled South Fence Machinery Ltd to identify and design features to facilitate the most economic and efficient manufacture of wire fence products.
The same dedication and exacting standards that placed South Fence Machinery Ltd at the forefront in Hinge Joint machinery has now done the same for Fixed Knot machinery
Two models of this fully integrated machine type are available – a 20 line x 2.61m machine and a 26 line x 3.05m. Both machines are capable of manufacturing two rolls at a time and can operate at speeds of 40 stays per minute.
South Fence Fixed Knot Machines have been designed to ensure long economic life with ease of maintenance and operation.
The direct stay wire feed system gives versatility of fence specifications and clear uninterrupted operator vision of the knotting boxes. Line wires can be added or dropped off at the top or bottom of the fence to overcome the necessity of shifting the knotting boxes.
The indexing crimping drum allows changes of stay wire spacing's to be implemented by a simple keypad operation with no other mechanical adjustments necessary.
The machine has a comprehensive arrangement of electric trip systems to ensure the machine stops in the event of wire tangle or breakage or incorrect machine function.
The take-up mechanism incorporates an electrically driven stripper for the easy removal of the finished roll.
All the above features are standard equipment and are included in the basic machine price, as are freight to the nearest main port and the commissioning costs.
A full and comprehensive risk assement is conducted on all South Fence machines.
Safety features include;
- 2mm punch panel guard system powder coated.
- Category 4 Light Curtains on both front and rear of the machine.
- Category 4 Interlock switches on all movable guards.
- Stand alone safety PLC to monitor all safety related control features.
- Where necessary Festo pneumatic safety valves and safety regulators are installed.
- Warning signage where appropriate.
