It often happens like this - you are in a hurry to go somewhere, get dressed in a hurry, grab a backpack, put the necessary things in it. And once - the zipper broke! What to do? How to solve this problem, and quickly?
It is necessary to assess the situation. If the backpack is intact and can still serve, repairing it will not be difficult. It all depends on the severity of the breakdown, which is easy to fix yourself if you had the materials at hand.
We will tell you how to fix a zipper on a backpack.
Possible lightning malfunctions
First you need to find out what happened to the castle. There may be several reasons for the breakdown. The main types of faults include:
- destruction of the lower limiter;
- slider failure;
- teeth coming out of their position.
REFERENCE. The main reason for lock failure is wear and tear of its internal elements and components.
This happens due to mechanical damage when fastening occurs abruptly, using physical force.
The condition of the clasp can also be affected sudden changes in temperature affecting the structure of the material from which the links or lock are made.
There are also frequent abrasion of surfaces, increasing the distance between components, microcracks. And dirt and dust, which impairs the work of the dog, and breaks in its suspension, due to which it is impossible to apply the proper force to the chain links.
Methods for repairing zippers
First you need to understand the type of fasteners, since they are different, depending on the type and style of the product.
REFERENCE. Zippers are divided into three groups: metal, spiral, tractor.
Repair tools
To troubleshoot the problem you will need:
- replaceable lock with suspension;
- a measuring device in the form of a ruler or a household centimeter;
- screwdriver;
- clamping tools;
- hammer;
- scissors.
Carrying out repairs
The main points of troubleshooting consist of the following steps.
- Bring together and clamp the increased distance between the links using pliers, which will also help when repairing the lower limiter.
- The gaps are tightened with hammer blows.
Replacing the runner.
Using a small hammer, carefully hit the edges of the lock, being careful not to hit the center. For better effect, clamping occurs on both sides with a firm stop. This method is intended for metal zippers. The same principle of firm stop is used for clamping with pliers.
ATTENTION! Actions are performed as accurately and carefully as possible so as not to break the part.
If the problem occurs due to the fault of the lock, it is replaced. To begin with, the characteristics of the slider and its number are determined, or measurements are taken with a ruler to purchase the same in the store.
Algorithm for installing a new lock
- The zipper opens.
- The limiter is removed.
- The new slider is inserted correctly.
- The removed limiter is compressed with pliers.
- The tape is being refilled.
The technology for removing and replacing it depends on the type of snake.. For metal zippers, replacement cannot occur without a screwdriver or scissors for cutting thick tape. With other species, the principle of replacing the dog is similar. The only difference with a spiral fastener is that to improve sliding, the tape is lubricated with paraffin, soft lead or even fat. But the latter methods are only suitable for leather or leatherette backpacks.
Prevention of breakdowns
To prevent fastener failure, the following rules must be observed.
- Carefully fasten and unfasten the runner.
- If the metal snake has just begun to come apart, repairs can be made using a vice or other clamp.
- The backpack must be zipped while washing.
- Use wax or pencil for preventive purposes.
- Monitor the cleanliness and operation of the mechanism.
By taking proper care of your snake and carrying out repairs correctly, you can wear your favorite comfortable backpack for a long time.
