So today, let’s talk about how to install a zipper. Before installing the zipper, you must first understand the structure of the zipper:

How to "make" a zipper? The installation methods of zippers are similar in different styles of leather goods, but generally speaking, the semi-open zipper shown below is the most commonly used.

This kind of closure Type zippers are mostly used in pockets. Since it is in a closed state, some lazy people can simply skip the installation of the upper and lower stops.

And this kind of Open zippers are generally rarely used because the upper and lower stops are not firm and are easily damaged.

Then here The installation tutorial takes the most comprehensive full-open zipper as an example. First, measure the length of the upper zipper, and cut the zipper cloth according to the measurement plus 1cm. When cutting, separate the zipper cloth first, and then cut it with a wallpaper knife. It is not recommended to use scissors as it will damage not only the teeth but also the knife.

Use needle-nose pliers to cut off three teeth on the upper, lower and both sides. Cut each tooth separately without damaging it. Do not hold the zipper cloth hard to prevent the zipper cloth from being deformed.

After cutting it off, use a lighter to lightly burn the edge of the fabric. The zipper fabric is called cloth, but in fact most of it is synthetic polyester. It will deform and melt when exposed to slight heat. Just burn it. Solve the burr effect and prevent off-line.

After cutting, start installing the accessories and prepare the zipper parts. They are the "zipper head", "top stop" and "bottom stop".

Use a flat mouth The clamp is installed with an upper stop. At this time, the zipper teeth are staggered with each other. In order to ensure the symmetry of the top stop installation, it is necessary to align the zipper teeth on one side and leave a sawtooth position on the other side. Clamp it after tightening.

Top stop completed The rear zipper puller can be installed. Here’s the key point: the downwardly aligned zipper teeth need to be in the right position. If there is one more or less one, the entire zipper will be uncoordinated. The general assembly method is to first place the zipper cloth into an outward shape, hold the two bottom ends, and at the same time place the zipper head along the way. If the order is wrong during installation, exit and reinstall.

Then install the bottom stop. Due to the previously reserved zipper cloth, we need to place it on the leather goods to see the actual range of zipper teeth that can be exposed, and at the final point Position, reserve 6 more tooth lengths according to the positioning points, cut off the excess teeth, and start installing the stop. The shape of the bottom stop is similar to two upper stops glued together, which can directly seal the sliding zipper head. Therefore, it is necessary to confirm the precise length of the zipper cloth before installing the bottom stop. It is also clamped with flat-nose pliers, and the installation of one zipper is completed.

Okay, think back for a moment. Do you still remember the zipper cloth I just mentioned? The current zipper cloth is polyester. Many, just burn it with a lighter when processing the edges. However, when it comes to the material selection of some high-end zippers, such as riri, their zipper cloth is still made of mostly cotton and cannot be sintered. What about edge processing? At this time, if you want to create a texture , we still need to use traditional methods. How to do traditional methods? I will teach you now.

First calculate enough reserved zipper fabric and make right-angle creases for it, as shown in the picture above.

Finally, the overlapping is bonded to increase the thickness and enhance the appearance.
