The history of barbed wire begins in 1874, when Joseph F. Glidden patented his invention. Success in the United States, the rapid popularization of this invention in Europe, huge sales volumes, commercial success, all this postpones the evolution of barbed wire for a long time until the First World War. It was then that the German military, known for its ingenuity, began to use ordinary barbed wire egoza.com to make spirals (Bruno's Spiral). There in Germany, due to a shortage of wire, they began to produce barbed tape from sheet metal. Around the same time, the need arose to increase the concentration of turns of barbed wire to create a more effective deterrent force. To achieve these indicators, stamped barbed tape, like previously ordinary barbed wire, is wound on drums, giving it a spiral shape. Since the tape was made of thin sheet metal, it could easily be bitten or cut using ordinary tools.
The experience of the First World War allowed us to work on the mistakes, and in the near future they began to reinforce the tape with steel wire, which made it possible to use sheet metal of a smaller thickness and save on metal consumption. This barrier provided a more durable defensive effect, was easily mounted and dismantled if necessary, in a word, it had all the necessary qualities for the rapid mobilization of forces.
Today, the symbiosis of razor tape and wire is abbreviated as ASKL (reinforced twisted razor tape). It is worth noting that to this day the spiral shape for barbed wire and tape is the standard. But let's get back to history.
ASKL forced the enemy to carry a special tool for cutting wire and, nevertheless, its design was still far from perfect. By biting off the top layer of razor tape, it could easily be unrolled from the steel base, thereby destroying the protective properties of the fortification.
In the 70s of the last century in America they solved this problem by inventing reinforced barbed wire (RBR) with partially rolled edges. This significantly increases the effectiveness of the defensive properties of barbed wire.
Years of commercialization of production, the desire of companies to save money on the manufacture of spiral barriers from ACL, leads to the fact that a significant design nuance is introduced into the original idea of \u200b\u200bconnecting turns of spiral barbed wire. To fasten the turns, they begin to use wire staples, the strength and duration of operation of which leaves much to be desired. Subsequently, staples for connecting turns of barbed spirals began to be made by stamping from sheet or rolled steel, which improved the reliability of spiral barriers.
Patent competition between the world's barbed wire manufacturers leads to the fact that at the beginning of the third millennium there is a division into two main camps, Concertina and Egoza. Spiral reinforced fences were registered in some European countries, North American countries, and Asian countries under the Concertina trademark, while in the CIS the largest manufacturers registered the Egoza trademark for the sale of barbed wire.
Large-scale production of Egoza barbed wire is being launched in the CIS, which is successfully sold in domestic and foreign markets.
The use of barbed wire on sea vessels as protection against pirate attacks played some role in the further evolution of methods for securing ACL products. Reinforced spirals have begun to be used on many ships on international voyages. But there was a drawback to using reinforced razor tape in a spiral - the inability to quickly install and dismantle it. So, during loading and unloading and other work, the fastenings of the thorns in some cases had to be cut off so that they would not interfere.
Inventor Yu.V. Tkachenko solves the problem of ease of operation of the barrier by developing a specialized engineering and protective system that allows the spirals to be quickly rolled up and deployed on sea vessels without harming their integrity. It is worth noting that Tkachenko owns a number of unique patents regarding the improvement of the structural and functional qualities of razor wire. The invention of razor wire made of composite materials can be considered a qualitatively new milestone in the improvement of barbed wire. Using this approach to the production of razorwire makes it possible to significantly reduce the cost of razor wire while simultaneously increasing such indicators as absolute resistance to corrosion, service life, and waste-free production.
