Pulley bar winding refers to winding the line on the pulley bar, used to lock the window or door, etc. The following is the winding method of the pulley bar:
< br >
1. Material preparation: To wrap the wire around the pulley bar, we need to prepare a coil and an appropriate amount of wire.
< br >
2. Winding: Place the coil on the pulley bar and begin to pull out the wire from the coil. Attach one end of the wire to the fixing point below the pulley bar, then begin to wrap the wire around the pulley bar, moving from one fixing point to another. A clip or pin can be used to hold the coil in place so that it does not detach from the pulley bar.

3. Ensure the tension of the line: while winding the line, ensure that the tension of the line is relaxed properly, too loose or too tight will affect the slide and may lead to the line falling off. The details of pulley rod winding need to be adjusted and explored according to the problems encountered in actual operation.

4. Ensure the stability of the line: After the line is wrapped, each contact point and fixed point must be checked to ensure that the line is firm and will not fall off. Finally, test how the window or door opens and closes.

It should be noted that the winding method of the pulley bar is different, and the specific details need to be determined according to your actual situation, as well as the understanding of the window or door. At the same time, pay attention to safety to prevent accidental injury or other accidents.
There are two main methods, namely direct winding method and cross winding method.
Direct winding method refers to the line from the pulley rod side of the first section around the pulley, and then from the other side of the second section back, so directly around a circle, winding is simpler, suitable for less bearing capacity requirements of the occasion.
The cross-winding rule is to start the line from the side of the first section of the pulley rod to bypass the pulley, and then from the opposite side of the second section of the cross-winding back, so that repeatedly cross-winding, higher strength, suitable for bearing capacity requirements of higher occasions. In addition, it is necessary to pay attention to the uniform tension of the line, the number of winding layers should be enough, and the direction of winding should be correct, so as to ensure that the pulley bar works normally and is not easy to fail.
Steps are as follows.

1. First, fix the fishing line to the reel and pass the end of the line through the pulley. When threading the wire through the pulley, pay attention to the direction to ensure that the wire can smoothly pass through the pulley.

2. Next, pass the thread one by one along the wire loop of the pole, and fix the thread to the reel at the end of the pole. When passing through the wire loop one by one, pay attention to the order and tension of the line to ensure that the line will not interweave or relax.

3. Assemble line sets and floats as required. Line sets and floats are assembled according to specific fishing requirements and can be adjusted according to your own experience and needs.
one
In general, when winding the pulley set, first determine the number of rope strands n that bear the weight of the load
two
Then wind the rope according to the principle of \"odd motion even fixed, from inside out\". \"Odd and even\" refers to the number of rope strands bearing the weight of the load, and \"moving and fixed\" refers to the moving pulley and fixed pulley. If n is odd, the starting end of the rope begins to wind on the small hook of the pulley; If n is even, the starting end of the rope is wound from the small hook of the fixed pulley.
three
It should be noted that when winding, the line drawn should be straight and tangent to the outside of the two pulleys.
