Breakage of secret zippers often leads to a stupor, because its structure is different from other types of fasteners. Secret zippers are spiral ones, when instead of teeth, a spiral made of synthetic fiber is wound or sewn onto a textile tape.
For this reason, a frequent breakdown on such a fastener is the failure of the runner or dog. The teeth simply cannot fall out unless they are mechanically damaged — cut or torn.
And even it is believed that if the dog broke, then the clasp will have to be changed entirely. But this is not always true. The slider on the secret fastener changes easily, but there are also nuances that you will learn about here.
Causes of breakdowns and features of hidden lightning
A special feature of hidden zippers is that the teeth are located inside out, and what is on the front side is covered with fabric. Therefore, on the finished product with a secret fastener, only the connection line of 2 parts of the fabric and the keychain of the dog is visible.
IMPORTANT ! On ordinary zippers, the teeth are sometimes also covered with a cloth. The secret is distinguished by the fact that the main part of the dog also hides under the fabric, only the keychain and the protruding part on which it is attached are visible.
Causes and types of breakdowns of hidden lightning when a slider change is necessary:
- the clasp diverges. The reason is a weak dog, it does not tightly press the teeth, and they do not fix among themselves;
- obstructed movement of the slider and divergence of the fastener to the bottom. The reason is that the dog is too compressed, such a strong pressure connects the teeth incorrectly, because of which they disconnect;
- the puller broke off. The reasons - poor-quality material of the castle, improper operation, the old age of the castle.
HELP ! Puller - keychain, suspension, tongue of a dog. Zipper - lightning, snake, clasp. Dog - a runner, a castle.
DIY repair materials
Repair of a secret fastener does not require a lot of materials, the main thing is to choose a suitable lock. You will need:
- slider of the right size;
- candle or lighter;
- scissors;
- needle with thread.
IMPORTANT ! If the lightning is broken on the finished product, take a lighter. It is not safe to burn the edges with a candle, because you have to lift the whole product and keep it above the fire.
How to insert a dog in a hidden zipper, instructions
There are several repair options, and they depend on the condition of the broken fastener. To insert a dog in a zipper with its native ends will require less effort than if you repair a fastener with cropped ends. Also, the action algorithm is different for a single fastener, and sewn into the product.
If the dog is not deformed
Consider several situations where you need to insert a slider into a hidden zipper. Please note that zippers are connected by clamps, then they will need to be cut.
Separately taken clasp with their native ends. The advantage of such a zipper is that there is a supply of fabric at the ends. The teeth there begin at a distance of 1-1.5 cm from the edge, and this makes it possible to freely enter the castle.
Algorithm:
- take the clasp so that the prongs look away from you, the key chain of the runner is at you, and the ends are on the same level;
- if the ends are frayed, lightly burn them with a lighter;
- insert one end of the fabric into the slider all the way into the teeth. Then insert the second part of the zipper in the same way;
- align the ends and grab them firmly with your thumb and forefinger;
- grip the slider with 2 fingers. Do not grasp the keychain because you will have to pull strongly;
- pull the lock down. At first it will go with difficulty due to parts of the retainers. Further it will go easily, and it will be possible to pull the keychain;
- Sew the ends in place of the catch.
Separate zipper with cropped ends. The peculiarity of such a fastener is that it already does not have a supply of fabric at the ends to insert a dog. It immediately starts with teeth and this complicates the process of inserting the slider so that all the lightning does not warp.
Algorithm:
- align the ends at the same level, and singe them to make it harder;
- position the zipper with teeth from you;
- cut one side by 0.5 centimeters;
IMPORTANT ! If the length of the fastener allows, cut 1 cm., It will be more convenient. Trim one side so that the lightning does not skew below.
- Take the keychain to you. Insert the long side of the zipper into it so that the end of the slider and the fasteners are on the same level;
- Now insert the short side of the clasp into the dog. It will be more difficult, because the teeth have already taken the place inside the castle, but when 1-2 teeth of the short side enter the slider, stop;
- take the ends of the clasp with 2 fingers, with the other hand take the keychain and start pulling it down. Pull until the prongs of both sides enter the dog and it goes freely;
- sew the end, forming a latch.
Secret lightning in a finished product. The secret zipper repair algorithm in the finished product is the same as in the separate one. But there is a nuance - the slider needs to be inserted so that it is on the front of the product, but initially it is inserted on the wrong side.
Fastener repair algorithm with native edges:
- trim the edges with scissors and lightly singe;
- take the end of the clasp with the teeth from you, and insert the slider with the keychain towards you;
- pull the dog through the clips;
- Now the keychain needs to be brought to the front side. Pull it into the hole that is between the fastener and the fabric of the product;
- pull the dog to the end, and sew the place of the latch manually or on a typewriter.
Fastener repair algorithm with short cut edges:
- take the zipper with your teeth and shorten one side by 0.5 cm;
- scorch the edges with a lighter to make them tougher;
- insert the dog into the long half of the clasp, flush with the edge. The runner is looking at you;
- insert a keychain between the strips of the fastener;
IMPORTANT ! Due to the fact that the ends are short, then the keychain will not work through the hole. Therefore, now it needs to be thrown to the front side.
- start putting the dog on the short side. Grasp the edges with 2 fingers, and pull the key chain down with two fingers. Slightly stretching the dog, grasp with 4 fingers the zipper on both sides - large and index. With your middle finger, push the dog down until it goes freely;
IMPORTANT ! Make sure that the lightning does not twist, its ends should be at the level you cut them. If the fastener is twisted, remove the lock and try again.
- Sew the end of the clasp into a snap.
If the slider is broken
If the dog is broken, then before replacing it must be removed from the fastener. To do this, cut the lower latch and pull out the slider. Fit a new one and sew the retainer in place. In some cases, the finished product will have to be slightly spread out below, because the puller is on the front side, and in order to remove the slider, it must be returned to the wrong side.
Now you know how to insert a dog in a hidden zipper. It remains only to practice. And keep in mind that this may not work the first time, especially in the case of cropped edges. You just need to fill your hand, and in the future this manipulation will not require much time and effort.
