How are Chain-Link Fences Made?

Chain-Link fences were first manufactured in 1844 through a process called “weaving.” The galvanized, metal wire is made into a flattened spiral. This spiral is winded past the blade, thus weaving itself into the previous spiral.  When this spiral reaches the end of the fence, it is cut near the blade.  Next, the entire spiral is flattened and the fence is moved in preparation for the next cycle.  This makes the end of every second spiral overlapping the first spiral.  Finally, the machine camps both ends and twists, thus making permanent links.  

Today, the updated manufacturing involves winding two wires around the blade simultaneously, creating a double helix.  A spiral is then woven through the previous spiral, allowing the entire process to go twice as fast without compromising the integrity of the fence.
