The South Fence Machinery Ltd Stiff Stay 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 have placed South Fence Machinery Ltd at the forefront of both the Fixed Knot and Hinge Joint machine technology have been applied in the design and construction of the Stiff Stay Machine.

Two models of this high performance fully integrated machine type are available – a 20 line x 2.0m machine and a 25 line x 2.5m dual fence machine which is capable of manufacturing two rolls at a time. Both machines can operate at speeds of up to 80 stays per minute and the patented South Fence knot forging system allows for the manufacture of a mesh as close as 50mm x 50mm.

Initially designed for the North American horse fence market the stiff stay fence features a distinctive smooth, strong knot and is now used in a wide variety of applications such as stock fence, game fence, security and construction.

The HMI or Human Machine Interface not only allows for ease of setting and adjustment but also reports constantly and accurately on the manufacture of product and machine status.

The innovative tri-drive feed unit ensures rapid and accurate wire delivery directly into the knot forging system.

The servo-driven indexing crimping drum facilitates the effortless change of stay wire spacings at the push of a button without any further mechanical changes necessary, eliminating long down times during change overs.

The finished fence is wound on to a variable torque take up system that automatically adjusts throughout the manufacture of the product. This ensures the most compact roll practical is manufactured for ease of handling and shipping. The finished roll is then mechanically removed from the slotted mandrel by the automated stripping system.

The Stiff Stay Machines include a comprehensive range of safety features including light screens, electric trip systems and guards that not only keep the operating staff safe, but also stops the machine automatically in the event of a wire breakage or tangle.

Like all South Fence Machinery Ltd’s products the Stiff Stay Machines are backed with our comprehensive warranty so you can be confident that you are purchasing some of the best wire fence manufacturing equipment available anywhere in the world today.

A full and comprehensive risk assement is conducted on all South Fence machines.
