How to use patches for bicycle cameras. How to seal a bicycle inner tube at home

No matter how hard a child tries to be careful in wearing things, little troubles inevitably happen: either a chocolate stain will remain on his favorite sweater, or his pants will tear. There is no point in scolding children for these minor troubles, especially if they can be easily put in order.
For example, winter outerwear sometimes tears and you have to patch it. This happened to us the other day. It seems like it would be possible to sew it up neatly, as some mothers do, but having sewing experience behind me, I want to advise you on another way out and I’ll explain why: when sewing up torn elements, you need a certain amount of fabric for strength so that the seam holds and does not come apart ( approximately 3-5 mm). This option is good if the hole is along the seam - sew it up and no problem.
In the case (as in the photo), it is better to eliminate the hole in another way - seal it on both sides. The main thing is to do this as soon as it appears before the edges fray.

How to apply iron-on adhesive to clothing to patch a hole.

1. Considering that the hole is “fresh”, there will be no problems with its elimination. There is a tear along the fabric, the insulation and lining inside remain intact, therefore, only need to be repaired upper layer fabric from the front side.

2. For this we need a piece of thin non-woven fabric and a thermal sticker. Both should be at least a centimeter larger in area on each side than the hole.

3. Carefully place the interlining inside through the torn front fabric of the product. Be sure to place the adhesive layer upward, that is, to the torn fabric itself from the inside.

4. Straighten it so that there are no folded edges.

5. Use a hot iron, carefully aligning the edges of the hole.

6. Apply a thermal sticker on the front side.

7. Iron it with a hot iron (you can use it through gauze if the fabric is afraid of getting shiny).

8. Let it cool and check that the thermal sticker is tightly glued.

9. In some cases, you can do without thermal adhesive only by internally gluing the sides of the hole with non-woven material. In this case, you should very carefully align the edges so that the interlining is not visible and match it to the color of the product (white, gray or black - I personally have not seen others).

For company, I just stuck the same sticker on the pocket of my jacket - it turned out like a factory decoration.

It’s unlikely that the thing would remain presentable appearance, if the hole was sewn up.

How to tape a bicycle tube:

1. Find the puncture.
To find the cause of a puncture, check the tire all the way from the nipple. Remove any glass shards or pebbles you see. Even if you found possible reason puncture, still check the tire thoroughly.
2. Remove the camera.
Release the air. Push the valve into the tire. If there is a ring on the nipple, unscrew it and store it in a safe place. On the side of the wheel opposite the nipple, push the bead under the tire bead approximately 5 cm. Do the same with the remaining beads. Bike guards can be purchased at almost any bike shop. Pull the bead closest to you until the bead of the tire rises above the edge of the rim.
Lifting the bead of the tire with the remaining beads, make sure that it completely slides off the rim. Take out the camera. Remove the entire tire from the rim—with the exception of the tightest tires, most tires can be removed by hand.

3. Inflate the chamber.
Inflate the tire and try to determine by ear the location of the air leak. I usually try to find the puncture site with my lips. If you still cannot find the hole, then try inflating the camera again and place it in a bowl of water. Now the puncture site is easy to notice by the escaping air bubbles. Before you start next step, be sure to let the camera dry.

4. Prepare your camera.
Select a patch required size. When in doubt, out of two patches, always choose the larger patch. Before sealing the camera, be sure to use sandpaper to roughen the surface of the camera around the hole. There should not be a single glossy area left. Place one drop of glue and spread it in a thin layer within a 2 cm radius around the hole. Wait until the glue dries. Apply a second thin layer of glue in the same way. Let the glue dry again - it should become matte, not shiny.

5. Attach the patch.
Inflate the camera a little to better see the puncture site. Remove the foil from the patch and press it firmly against the camera. The thin cellophane coating on the patch does not need to be removed. To prevent the tube from sticking to the tire, sprinkle the sealed area with chalk, talcum powder or road dust.

6. Check the inside of the tire.
Before installing the tube, double check the inside of the tire to determine the cause of the puncture. Once, after driving along a road along a river covered in hedge thorns, I found about a dozen thorns! By comparing the tube and tire, you can find the puncture site. Carefully run your fingertips along the inside of the tire to find the objects that caused the puncture and remove them.

7. Install the tire.
After repairing the tube and checking the tire for glass, thorns or other sharp debris, install one bead of the tire on the rim. Inflate the camera a little and install it in the rim. Insert the nipple into the hole provided for it. Starting on the side of the rim opposite the valve, use your thumbs to fold the tire bead (the part of the tire in direct contact with the rim) over the rim. Go over the entire wheel in the same way, leaving only a small section of the tire uninstalled. Using your thumbs, carefully install the remaining section of the tire bead.

8. Perform final inspection.
Check that the tube is not pinched between the rim and the tire bead. Inflate the tire until it is still soft but still maintains its shape. Make sure that the tire's circular mark runs evenly along the entire length of the rim. If not, then you will have to lower the tube a little and level out all the protruding places so that the bead goes evenly along the rim.
Inflate the tire to the recommended pressure and check again that the tire bead sits evenly and the tire does not bulge anywhere from the rim. Finally, check that the tread moves straight when the wheel rotates. If not, then you need to deflate the tire and repeat this step.

Important tips for repairing punctures:

When removing the tube from the tire, remember in which direction the tube was placed in the wheel. This will help determine the location of the puncture in the tube after the location of the object causing the puncture in the tire has been found.
Use a ballpoint pen to mark the puncture site with a cross so that you know it exactly.
If you don't have sandpaper, you can use stone and paving stones instead.
To prevent the beads of easily inflated tires from falling into the rim groove on one side and swelling on the opposite side, install a thicker rim tape or two rim tapes.
To make tight tires easier to take on and off, install the rim tape as thin as possible.
Follow the puncture repair procedure carefully. The last thing you need to install on the rim is the section of the tire at the point where the nipple is attached. Make sure the tire beads are as deep as possible into the rim groove. When installing some hard tires, you cannot do without beads. Use special edges VAR 425 to help with installation.

Determining the type of puncture.

Two adjacent small holes in the chamber indicate snake bite , which occurs as a result of the tube being pinched between the tire and the rim when driving over a sharp object. Also, these punctures are often caused by the tire not being inflated to the recommended pressure. Make sure that side wall the tires remained intact. Otherwise, you can't do without.

A hole on the inside of the chamber indicates that the head is to blame for the puncture knitting needles. Check the entire length of the rim and make sure that the spoke holes are covered with rim tape and that the ends of the spokes do not protrude beyond the inside surface of the rim. If they protrude, they need to be filed down.

A less common cause of puncture is rough edge of nipple hole. This puncture is located at the base of the nipple and it is not possible to seal the bicycle inner tube.

Create your owncamera repair kit:

Several patches;
Rubber glue;
A pair of plastic sides;
A piece of good sandpaper;
Small adjustable wrench (if using wheels with hex nuts);
Or a hex key (if using wheels with hex nuts);
Reliable ;
LED key fob (useful for);
A couple of spare tires (always carry them with you).

Everything except the pump needs to be packed in the seat bag.

Systematic tire inspection.

Check weekly for tread cuts, sidewall bulges and wear. Tires with cuts, bulges and tires with skin showing through the tread are not subject to further use. Remove any pebbles or glass found embedded in the tread. Use a tire pressure gauge to check the tire pressure. Tires inflated to the recommended pressure puncture less often and last longer. The recommended pressure is usually indicated on the sidewall of the tire.

Carry spare tubes and tires with you.

In the rain it is very difficult to patch up a bicycle tube, as the patch will not be able to stick to the tube. In such a situation, you need to install a spare camera, which you should always carry with you! A spare tube will also be indispensable in the event of a tire bulging from the rim or a puncture at the nipple attachment point.

Urgent bicycle tire repair.

Fold a large piece of strong polyethylene in half. Cut the piece to a size that is 10 cm wider than the cut and 5 cm wider than the tire. Remove the tire from the rim. Center a double layer of patch over the gap or cut inside the sheathing. Holding the emergency patch that should protrude from both sides of the tire, install the first bead of the tire onto the rim.

If required, install new camera and pump it up a little. Install the second bead of the tire, and install the sealed section of the tire last. Make sure the patch sticks on both sides. Inflate the tire and trim off any excess patches, which should stay in place just fine thanks to the tire's air pressure.

Greetings dear friend! I know why you came here - did you break a tire on your favorite bike after a good ride? Well, it doesn’t happen to anyone! Thorns, glass, nails, and other evil spirits come across us on the road and sometimes present surprises in the form of another puncture. But don’t despair, in this article you will learn how to properly seal a bicycle inner tube, because there is nothing complicated about it.

So you drove and enjoyed yourself calmly active recreation and the surrounding landscapes, drove onto a country road, without even thinking about the hidden “surprises” insidiously waiting for you somewhere down there. And now you are driving further, and at this time a thorn stuck into the wheel, just like some kind of leech. After a few kilometers, or maybe even meters, you begin to notice that something is wrong with the bike - it has become harder to pedal, controllability has worsened. Well, it's sad, you got a puncture! I hope you didn’t forget to take a spare one with you, because you’ll have to roll the bike a long way.

Well, let's step back from the lyrics and move on to practice. What to do if you puncture your camera? When you return home, immediately inspect the tire of the wheel on which the puncture occurred. Most often the thorn remains stuck in it. If you find this infection, then carefully pull it out with tweezers, because if you break off the thorn with your fingers, it will be much more difficult to pull it out. Ok, done! Next, we will act in accordance with step by step instructions suggested below.

Step 1

The first step is to remove the tube from the tire. Remove the wheel from the fork and disassemble the tire with special plastic spatulas, having first completely released the air from the tube, if there is any left there.

Step 2

After you take out the tube, be sure to check the inside of the tire for any remaining thorns. To do this, walk the fingers of both hands in a circle along the inner surface; there may be small thorns that are not always visible from the outside.

Step 3

Your next task will be to find and then neutralize the puncture in the camera. Take a household basin at home and fill it with water. Then pump the camera well and immerse it in water. Rotate it slowly, starting from the nipple, and when you see air bubbles, pull out the camera and trace the puncture site with a ballpoint pen.

Step 4

After marking all puncture areas, wipe the camera dry with a rag. Next you will need the following equipment:

Degreaser (96% alcohol, gasoline or nail polish remover);
Cotton wool or cotton pads;
A set of patches from a bicycle first aid kit (this includes glue and the patches themselves);
Match (needed for uniform application of glue over the surface);
Any heavy object (dumbbell, pot of water).

Step 5

Take a degreaser, moisten cotton wool with it and then wipe the puncture site with it (all dirt and paste from the handle are removed). Remember where the hole is and prepare the patch while the alcohol evaporates.

Step 6

Take the prepared patch and remove the protective foil from it. Apply an even layer of glue, the size of a pea, spreading it evenly with a match over the entire surface of the patch. Do the same with the camera. Let the glue dry for 5 minutes.

Step 7

After the glue has dried, take the patch and press it firmly against the surface of the camera. You, of course, can feel like a vice standing in this position for several minutes, or you can take a dumbbell, for example, and put it on top of the patch for half an hour. When the whole thing has settled down, you can remove the protective film on top of the patch and feel free to put the camera back into the wheel.

Let's sum it up

Congratulations, you have learned how to glue a bicycle tube on your own! As you can see, there is nothing complicated here and even a seven-year-old child can do this task. Maybe someone will tell you that you need to clean the camera with sandpaper before applying glue and this person will be right. Also, if he tells you that glue only needs to be applied to the camera, and not to the patch. Previously, I also cleaned it with sandpaper, but then I noticed that even without it everything sticks together just fine. And I apply glue in the old fashioned way on both surfaces to be glued, for reliability, as my grandfather taught. In general, try it, you will succeed! Also, be sure to watch my video, which I made especially for you, so that you understand everything as best as possible. Write to me about your result in the comments below. That's all for now!

Such a nuisance as a broken inner tube happens to cyclists all the time. If there are no car repair shops nearby, you have to solve the problem yourself. In this case, ingenuity, knowledge of older generations, plus life experience come to the rescue.

First stage: determining the damage

It’s not enough to know how to seal a bicycle inner tube. You need to be able to remove it from the tire and find puncture sites. To do this, completely release the air from the chamber. Then use a long screwdriver or some other suitable subject Carefully bend the tire by the rim. Do this a few more times. Having freed enough of the camera, then simply remove it with your hands. Now take the pump in your hands and pump it up again (a little). Wet your finger with saliva and run it near the surface. This way you can catch the air movement. Mark the puncture sites with chalk or something else. How to seal a bicycle inner tube if the hole was not found using the method described above? You pour water into a wide basin or bucket, lower the object you are studying into it, and by the air bubbles you can see exactly where you need to put the patches and in what quantity.

Stage two, preparatory

The damaged area should be sanded, i.e. cleaned. To do this, take a piece of sandpaper and carefully rub its grainy surface onto the area with the holes. Before sealing the bicycle inner tube, degrease the surface to be treated. Simply put, wipe with a cloth soaked in gasoline or universal solvent (available in the store). Both operations are performed not only with the camera, but also with the patch that is applied to the puncture. Along the way, the question arises about what can be used to seal it. Emergency kits are sold especially for such purposes, which contain everything you need: glue, solvent, patches, etc. Or find an old inner tube from a car or bicycle, cut out a small patch from it and process it using the method , described above.

Stage three: repair

Let's say you have a bicycle first aid kit. How to seal a bicycle inner tube? From a ready-made piece of rubber, remove the protective film, coat it with glue, apply it to the puncture, press it, put it under a press for 20 minutes or clamp it in a vice (if you are doing the repair at home). This time is enough for the patch to set. Pump up the chamber again and check the water for holes. If everything is in order, mount the wheel, inflate it, then you can ride.

How to properly seal a bicycle inner tube if there is no emergency first aid kit? With all the other necessary components in place, it is important to choose the right adhesive. Numerous “moments”, “universal” and “super” are suitable, just be sure to read on the tube itself what they are intended for.

Ideally, a special one (for rubber) would be suitable. Apply a small amount of it to the patch and the camera itself, wait half a minute/minute, connect both items. First press them with your fingers, then also place them under the press. Usually you need to stand under the load for a day (or read the instructions for the glue). Then carry out the verification procedure, after which you are good to go!

Getting a puncture on a bicycle wheel is quite simple: you can cut the wheel on a sharp stone, run into a nail or run over a thorn, for example, a rose hip, while riding a bicycle outside the city or in rural areas. The most important thing is to know how to seal a bicycle inner tube. Let's consider options for repairing the camera in difficult conditions and unforeseen situations.

What minimum should be included in the repair kit?

In addition to this small kit, you need to have pliers, small wrenches, “mounters” for removing the tire and tube, and a spare tube. These are the main tools that you must have with you not only on long trips, but also during an ordinary trip to the country.

Now we will look at alternative methods of getting out of the situation in the case when the wheel is punctured, and necessary tools No. There are many ways out of this seemingly problematic situation.

The wheel is punctured, or How to seal a bicycle inner tube to get home

First, release the wheel from the brake. If it is rim, you need to squeeze the brake horns and unhook the arc that holds them back. Next, you should disengage the eccentric and remove the wheel. If the brakes are disc, then the work is greatly simplified: immediately disengage the eccentric and carefully remove the wheel. To make it more convenient, turn the bike over, placing it on the handlebars and seat.

If the brakes are hydraulic, it is better not to keep the bike upside down for too long: air may get into the inside of the brakes, and this is undesirable. If the brakes are rim or mechanical, you can safely turn them over. Just place a piece of fabric under the steering wheel so as not to damage the switches and brake levers, otherwise the question of how to seal a bicycle inner tube will no longer be so relevant - you will have to repair the hardware.

Removing the wheel

To disassemble the wheel, use the "mounters". These are special plastic devices used to remove tires. Usually there are two of them in a set. If there are no “installers”, then you can use a spoon or an open-end wrench. In short, you need to find something that can be used to carefully remove the tire without scratching the rim and without additionally making holes in the tubes. "Mounts" are ideal because they have a convenient shape and are made of plastic.

We completely deflate the tube and hook the tire with one “mounter”. Its edge must be brought out beyond the rim. It’s not a fact that it will work right away, so a second “installation” will be needed. Use it to pry the larger piece of tire out of the rim, holding the first one. Then, moving little by little along the tire, remove it completely.

We identify the puncture site

Once the tire is off, remove the valve from the rim. That's it, the camera is free, you can look for a puncture.

If the puncture is small, you need to inflate the chamber a little and listen to where the air is coming from.

Can't find a puncture? Submerge the camera in water. If there is not enough water, dampen a rag and wipe the camera with it - at the puncture site, water will begin to bubble, informing you of the hole.

Gluing the camera

When a puncture (maybe more than one!) is discovered, remember where it is, and if there are several of them, then mark all the holes with chalk or a marker.

You need to think carefully about how to seal the bicycle inner tube and prepare everything you need to make it easy to work.

First, clean all puncture sites with a piece of sandpaper to degrease the rubber.

Then prepare the patches. If there are no special ones, then you can cut them out from the old camera. Also clean homemade patches with sandpaper. Apply glue to the camera and the patch, connect them and squeeze firmly. It is better to squeeze with pliers, after placing a rag between the rubber and metal. This is necessary to ensure that the metal of the pliers does not damage the camera and the patch. If the packaging says that after applying the glue you need to wait five minutes for the glue to dry, follow this requirement and only then apply the surfaces to each other.

Now you can assemble the wheel. After your first flat tire, you'll remember how to seal your bike's inner tube on the road.

Reasons for camera puncture

Most often, the wheel runs into something sharp: a stone, glass, screw or wire. This can happen to anyone.

But there are reasons that are associated with a negligent attitude towards your “iron horse”. For example, if the camera is punctured from the rim side. In this place it is often pierced by the head of the knitting needle. This happens because the tape that runs between the rim and the tube wears out. In this case, it is very difficult to protect it from the knitting needles. To prevent punctures, wrap electrical tape around the rim to protect the area where the spokes are. Next, put the old tape on top, or better yet, buy a new, stiffer tape.

If there are abrasions or cuts on the tube on the rim side, it means it was not pumped properly. Because of this, the camera was a little mobile when driving, which resulted in a puncture. And the last thing: if there are no holes, but the camera still deflates, then you need to check the strength of the nipple by immersing it in water. If this is the case, the part will have to be replaced.

How to repair a camera if you have few tools at hand

If there is no repair kit, then how to seal a bicycle inner tube without glue? Craftsmen found a way out long ago. You need to take a coin, bend it with pliers or, holding it tightly, hit it with a stone. Once the coin is bent, place a camera between its folded edges and bend the coin even further to firmly compress the puncture site. The damaged area will be compressed with a coin and you will be able to get home. This is one of the answers to the question: “How to seal a bicycle inner tube without glue?” A dubious method, of course, but many claim that it helped them out.

Want to know how to get to your destination with a flat tire? Now we will tell you how to seal a bicycle inner tube without a patch using water. Fill the pump with water and pump it into the chamber. The bottom line is that water will not be able to escape as quickly as air. You can ride on a “sealed” wheel for about half an hour, and this, you see, is quite a long distance. It also helps that you can add water periodically. It takes a little time to do everything, much less than pulling a bike and walking.

How to seal a bicycle inner tube with self-adhesive if this is the only material available? You can inflate the chamber and apply any piece of rubber to the puncture site (a condom will also work), wrap it with self-adhesive or adhesive tape. You can drive on such a patch for quite a long time, unless, of course, the road is paved. And if you pump up the tire as needed, you can safely get to your home or the nearest car service center.

If special means If you don't have it at hand, superglue will help you cope with the task. Let's take a closer look at how to seal a bicycle inner tube with superglue.

We cut out the patch, carefully clean it and the puncture site with sandpaper.

Apply glue to both surfaces and wait the required amount of time indicated on the tube.

After the time has elapsed, apply the patch to the hole and press very firmly. You can wrap the camera on all sides with a dry cloth and use pliers to pinch the gluing area through it. We hold it for about thirty seconds and release it - the patch is securely fixed. This repair method is perfect for both field conditions and home use.

How to seal a bicycle inner tube with wet rubber

The most reliable way to repair a puncture in a tire is vulcanization with raw rubber. Usually trucks are sealed this way, but what's worse about a bicycle? This patch will hold on most reliably. It is impossible to use this method in limited conditions, but anyone can do the work at home.

So, let’s find out how to seal a bicycle inner tube with raw rubber: soak it in gasoline, then cut out the piece needed for the patch and apply it to the previously cleaned puncture site. On raw rubber Place a piece of paper and place the “structure” under a warm, turned off iron. We wait until it cools down and remove it. All is ready! This method is the most reliable, but it can only be used at home.

In our article you will find answers to the question of how to seal a bicycle wheel. Remember that if you go on a trip (even a short one), take the trouble to take with you everything you need for repairs.
