How to tuck a five-strand overlock jack

What tools are needed for overlock threading and adjusting

These points can be determined during the production process. As a rule, the additional tools required depend on what part of the overlock needs to be adjusted at the time:

  • Thread adjustment. To do this, you need to stock up on four spools of different colored kinds. If the equipment is three-stranded, then three spools.
  • Checking the quality of the stitches. In this case, you need a piece of fabric from any material on which you can try how to sew overlock, and then, without regret, throw away.
  • Threading the left buttonhole. Due to its location, it is not as easy to reach as some people think. An ordinary pair of eyebrow tweezers will make this process much easier.
  • Bent or broken overlock needle. In the same category of problems is skipped stitches in the seam line. A common mistake of beginners, who either installed it incorrectly, or pulled the material very hard with their hands. Therefore, it is always advisable to have spare needles on hand.
  • Severe heating of the overlock equipment, or its failure. Caused by a lack of, or lack of lubrication. At a minimum, it should be used once every 6 months. A syringe that can be filled with oil will do the trick. It will perfectly reach and lubricate all the hard-to-reach areas.
  • Overlock knives do not work. A common mistake new overlock machine owners make is to start cutting and sewing all the possible materials that are available to them at the moment. This is a poor judgment. The original purpose of overlock knives is to handle protruding threads and trim the edges of very delicate and loose materials. So, for a beginner using a machine like this, it is best to have a spare set of knives on hand at all times.

Tucking overlock should be correct, as it can prolong the life of the device and save from various kinds of failures.

Threading process

Note that the work is done with the power off and the presser foot raised!

The first step for all models is to install the spool of thread on the stand with spool holders. The ends of the threads should always pass through the thread guides. Then you need to open the lid, according to the instructions for the model.

Threading a three-strand overlock

The following instruction will help you understand how to thread an overlock machine that uses 3 threads for seams. After installing the threads and opening the cover, the procedure is as follows:

  • To thread the left buttonhole, pass the thread through all the guides on the body provided by the manufacturer, and then insert it between the left buttonhole tension discs.
  • The thread is then led through the remaining thread guides (according to the diagram). Turn the handwheel to the right and thread the buttonhole with tweezers.
  • After all these stages, the thread is threaded through the left eye of the buttonhole.
  • Thread for the second buttonhole is also passed through the loop guides and thread tension discs and then threaded into the upper (right) buttonhole.
  • The next step is threading the upper thread following the instructions on the body. After the tension discs, the needle thread must pass through the needle thread guide, for which purpose the needle bar must be raised to the upper position by turning the handwheel. Thread is threaded from the front of the needle to the back of the needle and then threaded under the presser foot.

Threading a four-strand overlock

Threading a four-strand overlock is almost identical to a three-strand overlock. Start with threading the lower buttonholes, then thread the needles. It is important not to mix up the left and right needle tension dials, and to pass the threads through all the necessary thread guides.

Modern models can be equipped with simplified threading systems, such as F.A.S.T. (Brother 4234D, Brother 755D, etc).). For easy operation, there is a separate lever that moves the buttonhole to a convenient threading position, and a handy needle threader. The top range models from Babylock and Janome have an air stream buttonhole threader that just needs a push of a button.

How to set up the overlock after filling

So, the threads are in, you can start sewing. Take your time! Now you need to adjust the instrument. It can happen that the threads are loose after a bartack. They need to be corrected, otherwise the stitches won’t be straight.

Important! While thread colors may vary, thickness and composition may not. In at least one paper. It’s better to buy threads specifically for overlock in advance.

To understand if the tension is optimal, put the appropriate regulators in the middle position and do a test stitch. If all the stitches are straight, the thread runs smoothly and does not get tangled, then all is well. If something went wrong, experiment with the tensioners: loosen or, conversely, strengthen them.

By the way! Once again we advise you to look at the instructions. Usually there are recommendations for fine-tuning overlock.

How to tuck overlock: three-strand four-strand threading scheme

In some cases, the sewing process can’t do without the overlock. This device greatly improves the quality of the finished product by preventing the fabric from crumbling. However, some seamstresses do not use this machine because of the difficulties of working with it. They have a special concern about threading. The procedure is straightforward, but you only need to know how to start the overlock.

How to tuck an industrial overlock. basic tips and tricks

The process of quality sewing cannot be done only with an industrial machine, in order to neatly trim the seams and handle them so that the fabric does not shed afterwards, sewing factories, additionally use overlocks. Industrial overlocks come in three-strand and four-strand designs, but it’s usually the second option that’s used. The overlock may be small, but it is quite heavy, and tucking it in may not be easy.

To learn how to quickly and correctly tuck the industrial overlock, you will have to practice a little, but after obtaining the necessary skills, you can safely work in a sewing factory or create high-quality things right at home. And so, to learn how to properly overlock the machine, it’s worth understanding the overlock in more detail, which helps to understand the threading process.

What else affects the stitching?

The problem of poor quality stitching can also arise for other reasons, which you need to be careful about:

  • The threads aren’t threaded correctly. If adjusting the overlock using the tension adjusters did not help, try refilling the machine by following the instructions in the manual.
  • Dull or bent needles can make poor quality stitching, skip stitches, make a deafening knock while working. Check the point of the needle with a magnifying glass, and look for bending along the entire length. If necessary, the needle should be changed.
  • A blunt knife can also cause uneven stitching. To check the quality of its sharpening, you need to lift the knife and try to cut the thread. If it is easy, it means the tool is sharp.

Overlocks, especially those that are used often and for extended periods of time, need to be cleaned and greased often. Clean the machine from accumulated thread trimmings, lint and dust with a special stiff brush, opening the side.

Lubricate with special oil, with a grease gun, at least once every six months, if you use it a lot, once a month. Overlock machines need more lubrication than sewing machines, because they have higher rotational speeds.

Decorative stitches

Modern overlock models provide more opportunities for sewing exclusive things, because they can please the decorative types of stitching.


Flatlock stitch is a true flatlock stitch only used on flatlock sewing machines and quilting machines. On an overlock machine, there is only an imitation of it, which is created by a certain adjustment.

To create such a stitch the tension of the needle threads is reduced and the lower buttonholes are tensioned as much as possible. Flatlock stitch can be sewn into fabric elements. On the reverse, when joining 2 layers of material, a stitch resembling a flat stitch is formed. When worn, it is not very durable, in places of heavy load quickly falls apart, so it is rarely used in sewing. Flatlock stitch is best used for high relief stitching.

Roll (hemming)

It is also called a roller stitch or opikova, you can get by manipulating the tensioners of the overlock. Edge treatment looks like a twist inside-out stitch.

With this hemming on the product you can increase the waves on the ruffles by inserting a fishing line, make the edge of the skirt more elastic. This maneuver is used to overcast the edge of the petticoat to increase the puffiness of the hem. With its help you can not only process the edge of the fabric, but also simultaneously sew together the ruffles of the outfit. Often such a stitch is used in sewing dance costumes. Also role-role stitch looks nice on decorated parts of tulle and in knitwear.

Today I want to talk about needlework, sewing in particular, and how I started sewing, and how I chose the latest Miracle of Technology.

In this review I will talk about Overlock overlock machine JACK JK-E4-4-M03/333.

Despite the fact that this overlock is an industrial, professional overlock, it can be used by anyone who has ever sat at least once at the overlock.

It all started with the fact that by the genes that were passed down to me from my grandmother, I have always had a hankering for sewing, and the opportunity was not. That’s why I started sewing about six years ago. I sew only for myself and my family. I am in constant self-training, the good thing is that the Internet allows you to find not only free master classes, but if you want, you can buy good training workshops for a small price. So, having built one single pattern, you can use it to model both simple and complex things.

When I got into sewing, my knowledge was at the level of school base. This is the kind of knowledge almost every woman has. As I was sewing, I realized that one machine wasn’t enough for me. Straight-stitch machine in general is a separate song to talk about. Be sure to have a machine that will do overlock stitch and plain stitch, or divide the machines so that one does overlock stitch, and the other straight stitch, decorative stitch, and so on. I was not interested in reinstalling the machine to a different stitch each time, so the first machine I bought was. Merrylock. It’s a quilting machine. It’s a multifunctional machine that does different types of overlock stitches, but again, it can adjust from one stitch to the next. I realized that Meriluk does the stitch I need, but the rebuild takes a long time and I wanted to get a machine that will do in one action trimming, overlock edge and join stitch. The three-strand overlock handles only the edge, and I had to have a connection stitch, since most of the products I sew with knitwear and almost all work I do on the overlock.

In a video review, I noticed a JACK overlocker, and the master was pleased with it. I decided to trust her choice, not to break my neck and ordered the same overlock, but the generation of a little younger.

The machine comes with a table, because it is impossible to put the machine on a completely flat table.

There is a notch in the table to install the machine.

The table comes unassembled. If your man is a head-head, assembling the table together with him is not difficult.

Install the machine, install the tray that will hold the oil. How to install the machine itself is shown in the pictures, if it is not clear, there are detailed video reviews on the internet.

On the inner lid, which is open, there is a picture of how to correctly thread.

If you have never done this before, you will have to do some work. After doing this operation a few times, you will understand everything and refueling the machine in the future will not be any difficulty.

The overlock comes with thread. Overlocked four thread and in order to put your thread, just cut off each thread, tie the tail to the end of the desired thread and thread through, but only with a raised foot. No need to recharge the overlock each time. Naturally, there are cases where the thread is torn, then you have to fix it somehow. I personally found it was a revelation that the threads can be rewound without having to load the overlock every time.

The overlock uses only one stitch.

Since the overlock is a four-strand, it simultaneously performs trimming, trimming the edge of the product and the stitching that joins the parts of the product.

You can adjust the width of the stitch itself, you can adjust the pitch and differential.

You can adjust the sewing speed on this overlock, you can set the axis. If at first you are afraid to give a high speed, you can set a small and slowly learn.

The overlock is industrial, so there is no need for lubrication. Special holes in the machine need to be filled with oil. Pour about half a liter of oil, all the parts that are in operation are practically bathed in this oil, so do not need additional lubrication.

The machine has a safety screen that allows you to protect your eyes.

There is a safety barrier to keep your hands away from the knife. Frankly, the screen bothers me, so I lift it up and work without it.

What I particularly like about this overlock, that the device of the table includes a hole and a trough in which to go all scraps after work.

It’s just a song to me. My previous overlocker had a removable container that kept filling up and I had to get up and empty it very often. With this overlocker everything is great, all the scraps magically go somewhere under the table and disappear there somewhere.

The overlock works quietly, so quietly that you might wonder. and it works at all? If someone is sleeping next to you and you’re sewing, all the noise will come solely from you. You’ll hear the rustle of the material and the rumble of the scissors.

Personally, it’s the only one for me. I have to sew with my left foot now. All my life all my feet have been on the right side. With this machine it happens that the foot that lifts the overlock foot is on the right side, and the foot that starts the machine is on the left side.

If you keep working with your right foot, you get uncomfortable. So at the moment I am in training to work with my left foot.

When buying take into account that the overlock comes with a table and takes up a lot of room in the room.

The native backlight to work in daylight hours is enough.

Since I’ll be working in the evening, then I bought a special kit, industrial light.

The instructions for the machine when I bought it were not given to me, but I received them by email. In the manual in Russian, everything is written in detail: where to grease, where to fill, how to pour, how to service overlock

Although you can set the speed on the machine, the foot that starts the machine is very sensitive. So one awkward movement, starts overlock and you can at best ruin the fabric and parts of the product. In the worst-case scenario, as it happened to me, the needle-punched fabric went under the knife. I would like to say that my machine has coped decently with this test. The upper blade was not damaged at all, but the lower blade had a nick on it. Yes, I’m not arguing, but I managed to sharpen it at home on the emery machine. I didn’t do it myself, my men did it. So we coped with this issue perfectly. And there was no need to take the machine to repair. I put the bottom knife back in place after sharpening, and the machine cuts just as it did when I bought it. Feel as if the knife is new.

I made a red blouse with this overlock. Almost all of the pieces are sewn on the overlock, except for the two finishing stitches at the neck and bottom of the piece.

All the other places, especially on the sleeve, where there were several layers of fabric, plus there was a seam, overlocked took perfectly fine. Just cut it all straight and made an even seam.

I’m sewing a half wrap skirt right now. At the moment this skirt is hanging on a mannequin, it is very long. I’m waiting for all the edges to pull away in order to straighten the hem of the piece. The black stitch on the skirt is done with this overlock.

I am very happy with my machine. I used to give my machines a name. In my arsenal I have a sewing machine called Bastard, it lives up to its name.

This overlock I came up with another name. Because this machine is super and she has character (does not allow any unnecessary motion when working with it), then I called it a Super.

My opinion. If you sew, it’s a machine you should have.

Despite the fact that now there is a wide range of machines, I trusted a professional and not a bit of regret about it.

How to properly install the thread spools

Since this article will be about threading three-strand overlocks, then for example we will take overlock type Prima. over, almost any other three-strand overlock, including a Chinese overlock, is not much different from this model.

First of all, before you tuck the thread into the overlock, you need to prepare it. Extend and fix the creel, prepare the stands for the bobbins. If you will use a tapered bobbin, you need to get into the rack hole springs or install other special mounts. The spool or bobbin must be secured to the stand, otherwise it can “jump out” while the overlock is running, entangle the other thread, which will lead to thread breaks and you will have to spend a lot of time trying to re-tuck the thread correctly.

Pay attention to the little things. Overlock is very sensitive to any failure to comply with the parameters of its work, especially with respect to the thread, its quality, tension, feeding from the spool or bobbin, etc.
