How to knit grapevine knots?

The ability to tie rope knots is necessary not only for tourists. Nodes grapevine, weaving, straight and auxiliary can be useful in everyday life. During the journey, you may need to establish a temporary crossing, use a rope anchor to lower or lift people and cargo. In a special way it is easy to close the bag easily, if the tourist knows how the knot is knit.

Grapevine, straight, buglin, sea, fishing

The place on which the ends of the line, ropes, ropes are joined are confused in a special order, called a knot. The main number of ligaments was invented by sailors. There are more than 4 thousand connections for ropes for all occasions. Alpinists and tourists have found a special application of several dozens of this variety. Travelers use those who minimize the rope, preserve the fortress, do not relax arbitrarily. Along with this, quality is worth such as easy untying after a load.

Depending on the purpose, practical nodes are divided into several types:

• Grasping;
• Cushioning;
• Auxiliary.

In addition, you need to know that to connect the same in thickness ropes use straight or counter, weaving or grapevine (as knit - below). For safety and unhindered loops make a simple and Austrian guide, eight, nine. These nodes are good for uniting tourists into one chain.

Need to gain a foothold for the support or tree? Weave a hammer, a beeline or knit a stirrup. The ends of a line of different thickness are connected by an academic bunch, using scaffold or brach-sheet. Grapevine nodes are equally suitable in such cases. And, the greater the difference in size, the stronger the rope grasp.

Auxiliary and control: what is it and what for?

Among the enumerated variety, tourists use only 6-8 variants. Some of the compounds glide along modern synthetic ropes. Some of the sites are obsolete, and tourists have replaced them with modified and stronger ones.

The grapevine assembly, whose history continues, has traditionally been used for bonding both ropes of the same thickness and with different diameters. To maintain the confidence of the connection, at the working ends of the ropes an additional "control" is added. This is the name of additional nodules that fix the free edges of the ropes. This method adds reliability to the fastening, which is important in high-altitude mountain crossings. Control units knit along all the main anchorages. However, double fishing and weaving do not require additional security measures.

Auxiliary or special nodes tourists use for self-insurance, rescue, lifting, lowering, carrying cargo. "Amphora" fix vessels with a neck for transportation or placing in the river (for cooling the drink). The marking units denote the ends of the ropes.

What reduces the strength of the rope?

It is impossible to use twine without a single nodule. But it is only necessary to tie at least one tourist node (grapevine or another), as the strength of the rope is slightly reduced. This is due to the change in tension in the bends and the cutting of some fibers in the joints. And with a frozen or wet twine, the fibers are exposed to ice crystals. During the load, at the kinks and loops the forces are distributed unevenly, the tension of some threads is greater, the others are weaker. The resulting forces in the transverse fibers of the bends create an additional, unnecessary strain on the straight sections of the rope. The influence of some knots reduces the strength of the rope to 35-60%. Despite this feature, any ties, including the grapevine nodes, do not change the basic dynamic qualities of the climbing lasso.

How to keep and whether it is necessary to clean the ropes?

In addition to the practical knitting skill of knots, it is important to properly store equipment and take care of ropes. Experienced tourists pay enough attention to cleaning and packing their "assistants" in climbing the peaks. The first thing to do from time to time - is to wash by hand in warm water with soap. Dry better in the shade in the breeze. Store the ropes, spreading from below a dense cloth or awning, in a place where the equipment is not threatened by contamination with chemicals, sand or earth.

Before the next campaign should carefully check the integrity of the ropes, no damage. It is important to remember that to worsen the condition of the rope may be heating from downhill or friction against stones.

Advantages over the counter node

How to tie a grapevine knot? Sometimes it is called "double fishing", sometimes - "double weaving". What makes him so fond of tourists climbing? It should be noted that this method is one of the most durable. Using this connection, you can splice the ends of the flat ribbons. Fixing safety lines, loops - braces, application for connecting different in size ropes - all this is available to double knots.

With the use of graptvine, there is no need to make safety harnesses. This contributes to the safety of the tourist, as it saves time and length of the rope. Another important quality is considered to be a minimal effect on the weakening of ropes, about 6% of strength is lost. This coefficient is not available to other nodes of similar strength.

Specific tourist terminology

For a better understanding of the interesting and useful process of joining the ropes, we list the main and generally accepted designations for loops, ends, and crossings. So:

• The main one refers to the fixed or loosely lying end of the rope, over which weaving occurs;
• Running or working - this is the moving part of the rope;
• An open loop is not a crossed, half-fold piece of twine;
• Callus called closed, inverted bend on the rope;
• A knot begins knitting the household knot known to everyone;
• Inns - is the girth of a support or tree without crossing;
• By a slug is called the capture of an object by a complete revolution of the rope (by 360 *), at which the ends of the rope "look" to the opposite sides;
• The half-bayonet is a turn around the support, followed by a rope crossing its end perpendicular (without passing under the loop).

Sequence of preparation of a double weaving compound

Grapevine how to knit? The node is composed of semi-nodes, which are alternately tied with rope edges. First, the ends of the rope are laid side by side, towards each other. One of them is twined two times with twine (make two slacks), pass through the turns of the received spiral and tighten. With the other end do the same. Then you need to pull both twines in different directions until the tightened half-nodes come together. The length of the working tails should be 12-20 cm. Control units are not required; the connection is tightened tightly with the load.

If it is required to untie the double fishing capture, first pull the nodes in different directions. It is difficult to do, but possible. Then relax and untie one part. After pulling the rope from the second half-node, it is easy to untangle.

How to learn how to quickly tie a grapevine node (photos and tips)?

Sometimes a tourist has to fasten ropes in extreme conditions. We need speed and good practical skills. If you hang on insurance or barely keep balance on a scanty ice rink, every second is expensive. It helps "motor" memory, in which the climber acts, without hesitation, hands move mechanically.

For mastering dynamic skills, the grapevine knitting pattern is applied and the following methods are used:

1. Using the features of visual memory, it is necessary to learn consecutive drawings and instructions. Multiple training in tying "without a hint" will allow in the necessary situation to easily recall the whole process and the answer to the question of how to make a grapevine node.
2. Remembering the exact sequence of movement of the ends of the rope in the course of practical work on the connection creates in the head the necessary algorithm of actions. Quality and speed depend only on the number of repetitions.

If you use these two methods alternately or in combination, the brain and hands will learn not only the grapevine nodes, but also other special connections. Instructors recommend immediately to accustom yourself when tying any knots to leave for safety reasons a rope "tail" of at least 5-7 cm in length.
