Last year, I visited the city of Dzerzhinsk in Nizhny Novgorod. The purpose of my trip was a factory "Rope"Where I went at the invitation of the company Kuvalda.ru. The plant manufactures ropes and climbing ropes. When I went to the factory, I was expecting to see the usual production and see how weaved and wove ropes. What I saw at the factory, I was amazed. I am sure it will hit you, too.
The plant employs modern equipment, but in one of the shops of the plant remained a unique production - "lift". This production runs from the date of opening of the plant in 1875, and it works so far on the same equipment, which is already 140 years old! It is possible that this is the oldest manufacturing facility in the world that is still in use today. I recommend the factory to apply to the Guinness Book of Records. By the way, the plant is 55 years older than the city in which it is located.
Cable car - it is a huge hall, half a kilometer long.
In the first step of production braided strands.
Bobbins mounted on a creel yarns - a frame arranged in several tiers axes. The larger the diameter the rope, the greater the number of filaments required for its production, the greater the seats in the creel.
The yarns are pulled through bundles of calibers - the group of holes arranged in concentric circles.
Strands emerge from calibers.
Strand attached to a single spindle machine hooks, moving on rails.
This machine 140 years and it works as good as new!
There is no electricity - a purely mechanical machine. He moves and all its mechanisms work due to the rotation of the side wheel through which prokinut drive cable extending along the entire shop.
First, the rope pulling the steam engine, now - motor. Just imagine: the equipment once set in motion by steam!
This mechanical machine is controlled by three rudders and four arms.
140 years ago there was no phone and two-way radios and communication system was necessary. Shop a long, noisy equipment and 500 meters shout useless. Since those times preserved signaling system that allows working on the movable machine to transmit signals at the beginning of the working plant. These are three of the rope, stretching over the cable car.
Worker pulls the rope and the bell rings at the end. Bell is also 140 years.
The movable machine pulls the strands to the entire length of the cable car and twists them.
In a single pass may curl up to 12 strands. To strands while pulling no slack, do not get dirty, and have the same tension at regular intervals under these backups are substituted with teeth.
After the movable machine pulled the entire length of the strand cableway, they are connected to the rope stranding, three strands in the rope. At the same time can svivatsya four rope. In order to lay the strand in the rope smoothly, they are passed through the cone located on the movable trolley.
When the rope stranding length decreases. Strands 300 meters in length when forming the finished rope stranding length of 230-250 meters.
This is one of the latest cable cars in the world - they were replaced by much more compact kanatovyuschie machines, but the cable cars there many advantages - they can twist the rope from any fibers, synthetic or natural, and the rope diameter is practically limited. Kanatovyuschaya machine is designed only for one of the rope thickness, a cableway rope can build any thickness. Here's a rope (and it is almost 10 centimeters in diameter) can twist only by cable car.
Threads for cable car (called rope-yarn) wove out even more thin strands of modern stranding machines.
Look at the video at the end of this article, how the coiling. That's impressive.
Thin ropes are doing on kanatovyuschih machines.
The frame is rotated at high speed around the coils with filaments, coiling them in the blank for the rope. Then, in a second section of thin workpiece three wove into rope.
The plant makes the ropes as the synthetic fibers, as well as from natural raw materials. Here is a classic hemp rope (They are now used mainly for decorative purposes).
jute rope.
Cizalevy rope
Ropes made of cotton.
Rope made of linen.
Polypropylene and polyamide ropes We are now almost completely replaced natural ropes in navigation.
The main products of the plant are now - ropes for rope.
In the center of the rope bearing white threads running parallel. Around them woven colored threads. Weaving is performed due to the movement of coils of thread.
Simultaneously in the shop lagging several tens of ropes with a diameter of 4 to 12 mm.
Machines for thin ropes weave them from four.
Bright patterns on ropes made not only for beauty. Each pattern encodes the type, thickness and strength of the rope.
Of course, the whole process works unique cableway, stranding ropes and weaving ropes clearer and more interesting to look at the video.

thanks to the company Kuvalda.ru for the opportunity to visit the factory. It was very interesting, and I hope you have been interesting to see the production of a unique, preserved since the last century.
