What do the numbers mean?
The numerical designations refer to the size of the teeth: they show the width in millimeters when the zipper is closed. Markings are applied to the slider from the inside. The shape of the upper part of the tongue depends on the type of links.
Metal teeth come in 3, 5, 8, 10 millimeters, the top of the slider has a triangular shape. Molded plastic teeth (tractor) - 3, 5.7, 8, 10 millimeters, oval or trefoil-shaped runner. Twisted plastic links (spiral) - 2, 3, 4, 5, 6, 7, 9, 10 millimeters, the slider resembles an oval. The longer the teeth, the stronger the connection against tearing and stretching.
Metal fasteners
The teeth of a metal zipper are made of flat brass or nickel wire. The shape of the links is asymmetrical: on one side there is a protrusion, on the other there is a recess. The connection with the braid is two-way. The quality of the clutch is high, but due to the misalignment of the teeth, the slider may “stick.”
Tractor zippers
The fastener consists of wide plastic teeth attached to a thick band on one side. The shape of the links resembles a caterpillar track. The advantage of such a zipper is the wear resistance of the links. But in terms of the fastening method, it is inferior in strength to metal and twisted fasteners.
Twisted clasps
A zipper is made from a fishing line rolled into a spiral. The fiber is wound or sewn onto the braid. The adhesion is formed by the fiber protrusions on both sides.
How to replace correctly
The procedure for replacing the matrix depends on the specific TV model. Differences in the procedure for disassembling and installing a new element are associated with the unequal design of the devices. Screws or latches are used as fastening elements. The TV is disassembled from the front or back.
When accessing from the front, release the latches holding the facing of the television panel. After disconnecting the latches, access to the matrix, screwed to the body with screws, opens. To dismantle, remove the fasteners on the rear wall, then install a new component and reassemble in the reverse order.
Since the case uses screws of different lengths, it is worth remembering their positions. Having disassembled the case, all that remains is to remove the matrices and install a new screen.
The matrix installation procedure itself is not particularly difficult, but it is important to follow the sequence of actions. In particular, you need to perform the following steps:
- After disassembling the case, a matrix is visible on which electronic boards and cables are fixed. The components are disconnected after first photographing their location.
- Disconnect the cables along the perimeter of the TV. In some types of devices, the cables are hidden under the frame.
- Having removed the matrix, it is placed next to the working one and the modules and electronic boards are transferred one by one. Immediately after transferring the board, the corresponding cable is connected to it.
- When a set of modules is connected, the case is assembled and the functionality of the display is checked.
In order for the device to function correctly, it may be necessary to match the new matrix to the modules. To do this, you need to turn on the TV, go to settings and launch the corresponding function. The detailed process is described in the instructions supplied with the equipment and may vary slightly.
Installing buttons and rivets without a press
If you are smart, you can do without a press and special tools. To install the button, you will need a hammer, a bat (bolt) or even a simple needle and thread. It all depends on the type of fittings.
Sew on buttons
Does not require the use of special tools. The easiest way to attach sew-on snaps to clothing is. All you need is a sewing needle, thread to match the fabric and the buttons themselves. The more holes they have, the better.
Instructions:
- Place the metal piece with the bolt on the smooth side against the face of the bottom of the product. Sew on.
- Place the metal part with the recess on the wrong side of the top of the product. Use a needle and thread.
Make sure that the 2 parts of the button are located opposite each other, and the fabric does not form wrinkles. If in doubt, install the bottom part with the bolt first, coat the protruding part with chalk and stamp on the opposite side.
Ring
Perhaps the most common type of button. They are used in tailoring clothes, including jackets, as well as in the manufacture of wallets and bags. They come in different sizes and colors and are mostly made of metal.
The ring button consists of 4 parts and looks like this:
It is connected by inserting a small ring into a large one. Hence the name.
How to install a ring button without a press?
- From the inside of the bottom of the fabric, insert a metal piece with a leg (more inconspicuous in appearance).
- Place a wooden block or something hard under it.
- Cover with a piece with a narrow ring.
- Armed with a bat and hammer, carefully flatten the protruding leg. You can use a suitable size bolt.
- Take the remaining part with the leg (it is usually prettier and better built) and insert it from the front side of the top of the product.
- From the wrong side, place the part with the ring on the leg. Place it on the beam and flare it again. Ready!
In a similar way, you can install plastic ring buttons without special pliers. Only instead of flattening the legs, they should be melted. At home, a soldering iron or a hot nail is used for this.
Alpha buttons
No less popular buttons. They have a spring mechanism and a convex pin. You can see the difference between the ring (2) and “alpha” buttons (1) in the photo:
Inserting them into a jacket or other product with your own hands is more difficult. The reason for this is the pin, which can become wrinkled when flared. To prevent this from happening, you should drill a recess in a wooden block for the convex part of the button.

What to do next:
- Install the part onto the bottom of the product. To do this, take a simple rivet with a leg and thread it from the inside out. Attach the part with the bolt on the front side. Turn it over and place the convex side into the hole drilled in the block. Tap lightly with a hammer on the top (from the inside).
- Next you need to assemble the front part of the button. Insert the rivet with the leg into the hole. Install the part with the recess from the inside out. Armed with a bat (bolt, blunt nail), flatten the leg from the wrong side.
If you often have to install rivets and buttons, then it is worth purchasing at least a minimum of tools: a washer, a standard size bit and one with a recess for the button bolt. The buttons are placed on the washer with the front side so that they do not wrinkle, and with a special bat you can rivet the product in literally 1 minute.
Rivets
Along with functional buttons, decorative rivets are often used in clothes: figured, with pebbles, spikes. They usually have sharp protrusions on the reverse side.
Inserting them is as easy as shelling pears:
- Pierce the fabric with the teeth.
- Press something hard against the rivet. The fabric should be taut and the rivet should fit snugly against it.
- Fold the teeth from the inside out. The easiest way to do this is with a flat screwdriver.
There are also rivets used to secure fabric stitching. Holnitens are often used in products made from denim and leather. This is what they look like:
Installation of this type of rivets is quite simple. The main thing is that the length of the leg matches the thickness of the fabric.
- Insert the part with the leg into the hole from the wrong side.
- Cover with a cap and place face down on a wooden surface.
- Lightly tap the rivet from the inside out with a hammer.
The buttons are inserted into jeans in the same way. The only difficulty is preserving the front part. To prevent it from being wrinkled or scratched, the rivet is hammered in from the inside out, and a rubber or leather gasket is placed under the front side.
Now you know how to install buttons yourself. Home renovations will save you time and money. If you doubt your abilities, try practicing on an unnecessary piece of fabric. You will succeed!
Options for attaching to clothing
In principle, buttons of any type and material perform one function. But to secure fasteners on things, two fastening options are used.
Sew-on method
Suitable for installation of two-piece fastener. They are sewn by hand in such a way that the seams are invisible from the front side of the items. Moreover, the top element of the button is installed first, and then the bottom one. Both metal and plastic products are used to decorate clothing:
- plastic components do not guarantee strong fixation and therefore are most often used as an auxiliary element. As a rule, they are very popular when decorating children's clothing. Also attached to the corners of the collars of men's shirts, to the straps under the fastener;
- metal sew-on buttons are used as fasteners for outerwear. For a fashionable wardrobe design, you can cover the buttons with fabric. If you choose textiles of the appropriate shade, then metal fasteners will be invisible on things.
Installation of punch buttons
Widely used for sewing sportswear, outerwear, and denim products. The button set consists of two upper and two lower parts
During installation, it is important not to confuse: the “lid” of the fastener is located on the front side of the upper fabric of the item, and the “leg” is located on the back. And accordingly place the remaining two elements of the button on the bottom field of clothing
Before installing the fasteners, special holes are first made in the fabric. We must try to ensure that the diameters of the hole in the material and the leg of the button match or the hole is slightly smaller. The parts are secured with a special tool, which can be purchased separately or in a set with fasteners. The equipment is equipped with a special press matrix and special attachments - punches (of different diameters). At home, when installing buttons, craftsmen use an ordinary hammer, a Phillips screwdriver or dowel, a wooden block, pliers, or a knitting needle.
What glue is suitable for repairing truck awnings?
The awning is a canvas made of synthetics, banner fabric, tarpaulin, PVC. For the repair of these materials, only certain compositions are suitable, ensuring reliable connection of several spare parts with each other.
Special glue for PVC “Winstik”
Winstik adhesive solution for PVC allows you to create a strong and transparent seam that is resistant to the influence of liquids, while maintaining its elasticity. The composition dries within a couple of days at room temperature.
"Desmokol"
Polyurethane adhesive "Desmokol" is intended for repairing PVC fabrics. The solution is transparent, so it does not leave marks or streaks after drying. Due to its easy flammability, contact of the substance with heating appliances or open fire should be avoided during operation. After application, the solution provides a strong connection of the surfaces, without the risk of displacement and tearing of the patch from the awning structure.
"Cosmofen"
The Cosmofen mixture has universal characteristics, which allows it to be used with any materials. Quick-setting cyanoacrylate adhesive is easy to apply and requires tight compression of the treated area with a press for a strong connection. The solution endures ambient temperatures of up to +80 degrees, so the seam should not be exposed to more heat to prevent the glue from melting. Due to the release of toxic components when using Cosmofen, it is necessary to repair the car awning in a constantly ventilated area.
Rapid
The thermoplastic composition of the Rapid brand reliably eliminates defects on the awning, maintaining the tightness of the canvas in the damaged area. The adhesive must be used in combination with a hardener and heated before application. The solution is suitable for repairing fabric awnings.
