Tucking in an overlock
When creating clothes without overlocks can not do. They are capable of high quality sweeping around the edges of all fabrics. The overlock can be used to accurately mend fabric elements and decorate garment seams.
Stitches are stretchy and reliable, resulting in long-lasting wear and tear. Such a technique requires proper attention. Many needlewomen dread working overlock machines without knowing how to correctly tuck the thread into the machine. The following article provides detailed instructions on how to install the overlock thread.
How to adjust the overlock after filling
So, the thread is inserted, you can start sewing. Take your time! Now you need to adjust the machine. It happens that after threading, the threads are loose. They need to be corrected, or else you won’t get straight stitches.
Important! If the threads may differ in color, they do not differ in thickness or composition. In at least one job. It is better to buy in advance threads designed specifically for overlock.
To see if the tension is optimal, set the dials to the middle position, and then sew a test stitch. If all the stitches are even, the thread runs smoothly and does not tangle, then all is well. If something went wrong, experiment with the tensioners: loosen them or, conversely, strengthen them.
By the way! Check the manual once again. There are usually recommendations for fine tuning an overlock machine.
Tuning after refueling
For fine tuning, you can thread the overlock with different colored threads to easily see which thread tension is the problem.
For all needles and darning loops should use the same thread, preferably specially designed for overlock.
Initially, set the thread tension values on the adjusters to the middle position (according to the manual). Then perform a test stitch and, if necessary, loosen or tighten the tension of specific threads. Usually, the instructions give examples of incorrect tension and recommendations for tension adjustment. After making each change, run the test line again until the optimal result is achieved.
Stitch length and cut width, as well as the differential feed, according to the type of fabric and sewing. Adjustable foot pressure (on some models) allows for better stitching in thick or thin materials.

Correctly threading an overlock the first time takes a lot of time, but with experience, it will be quicker. Color-coded markers and diagrams on the body make it easier. The combination of the right setting for the specific task and quality threads ensures a high level of seam processing, even at home.

bobbins. Then place spool on pin with slotted side and place on top
If thread slips off the bobbin while threading and/or sewing, set
Grid on the spool, as shown, to prevent interference. Sacks are supplied with the machine.

The thread tension is released when the presser foot lifter is raised.
How the threading process is performed
And so, the first thing a person does when he sees an overlock, he is taken to installing the bobbins on the holder and threading the needle thread, for these are the simplest processes. When it comes to the buttonholes, things are much more complicated.
Looking at the threading diagram, you will note the fact that each thread path is marked in its own color and, this greatly simplifies the task, in addition, if the direction arrows and other verbal cues. Threading should be done in turn, sequentially, so that they then do not get tangled with each other, and the process of threading itself is as follows
- The thread from the first bobbin is passed through specific areas and inserted into the needle;
- the second thread, according to the diagram, is led through specific areas of the device body and inserted into the buttonhole, using tweezers;
- Similar actions are carried out with the remaining threads;
- check the correct installation and tension of the threads, as well as the quality of fixing the knife.
If everything is set correctly, you can start sewing, following the same principle as with a normal machine. It is worth noting the fact that some users, so as not to constantly bother with threading, go for a certain trick.
People simply take the tip of the thread that is running out and, tie it to a new thread, then start sewing and, that way, they don’t have to repeat the threading process all over again.
It is worth noting and the fact that the industrial sewing overlocks of the new generation have become more automated, so the process of threading has been greatly simplified, which greatly facilitates human labor.
How to properly tuck the thread into the overlock?
A novice seamstress or a craftswoman who has never worked with overlock, it may seem that special skills and knowledge are required to independently prime this sewing device. However, once you tuck the machine in, it can be done almost blindly. How to thread a three-, four- or five-thread overlock machine?
If you can cope with threading in the Chinese three-strand device, this procedure will not be a problem when working with any model. Do it this way:
- Thread through all the thread guide holes on the machine body.
- Insert the thread through the tension device on the right buttonhole and then pull it out in the lower direction.
- Thread through the eye of the needle, pulling it back through the foot. At the end of the procedure, make sure that the thread is properly threaded. To do this, try stitching on waste material.
Threading a four-strand overlock follows the same pattern as a three-strand overlock, except for a few things. The first type of machine differs from the second in that it is equipped with two needles. Thread for the left needle runs through the left tension device, for the right, respectively, through the right.
Before threading a four-strand device should be considered that in it the right puller corresponds to the first buttonhole, located on the left, and the left. the first element designed to capture the needle thread in forming a chain stitch, which is located on the right. If this procedure has any special features, the machine manufacturer places the diagram on the machine. Some models of such overlock machines are equipped with a system of F.A.S.T. It is much easier to thread the lower and upper buttonholes with it.
Five-strand, or industrial overlock
Unlike older machines, all modern machines have a needle threader. Usually glued to one of the flat surfaces of the product. In any case, a detailed description of this manipulation should be in the manual for the sewing device.
Many manufacturers of modern industrial overlocks mark the pointers for each thread in different colors. If the threading is urgently needed and there is no time to learn how to do it, it is much easier with these colored markers. In the absence of such pointers they can be made on their own, marking the right places with nail polish of different colors. Water-resistant felt-tip pens can also be used for this.
Tucking the needle thread in a five-strand overlock, you must follow the following sequence of steps:
- Pull the thread from the spool and thread it into both holes located at the back of the thread guide.
- Guide the thread under the thread tension washer by pulling it toward you.
- Pull the thread through the hole in the second horn and thread guide, which is located on the needle bar. Pull the thread down through the eye of the needle.

How to change the color of overlock thread
Sometimes it is necessary to change the color of the thread. Before tucking the thread into the overlock, carefully trim the spool on the machine at the level of the thread holder. The tip of the prepared bobbin is tied to the remaining tip of the old bobbin.
thread is pulled through until the knot is behind the presser foot (another option is to pull through several stitches);
Raise the foot, gently guide the knot through the fabric;
continue sewing until the knot approaches the eye of the needle;
The steps must be repeated until the knot is no longer in the way.
Stitch and cut size
Set the width and length of the stitch is necessary to improve the quality of the resulting stitching. For each new session of work it is necessary to choose different parameters of settings. For standard jobs, this machine has a universal mode that combines values suitable for most fabrics. For small stitches, there is no need to adjust the machine.
The stitch length in this setting is two and a half to three millimeters, which is great for thin fabrics and medium-thick materials. Stitches shorter or longer than this value can result in a poor quality seam and tighter fabric.
The stitch width that is selected before starting work should match the width of the cut line setting. The value selected on the machine controls processes such as:
The highest stitch width is used when working where most of the fabric needs to be placed inside the stitch. The lowest setting is difficult to work with because the optimum thread tension is so great that the threads start to break intermittently.
Narrow stitch is convenient to use for role stitching or other specific work.
Width adjustments are made with special screws provided by the design. Turn them until they are in the desired position. The operation must be carried out in stages, checking the stitch length on the piece each time a small twist has been made.
In addition to the tension regulators for each thread, the body of the sewing machine has a special toggle switch with a scale of stitch size: from 2 to 5 mm. The choice of the desired stitch size is dictated by the characteristics of the fabric to be worked with. Users of the machine need to take into account the following standards when adjusting.
- The edges of delicate materials like cambric, quilting, georgette, chiffon should be sewn with a 2-3 mm stitch. Threads 0-90 are recommended.
- For medium density fabrics (calico, calico, gabardine, poplin, fine cloth) threads 0-80 and stitch size 2 are recommended.5-3.5 mm.
- Knit or heavy weight fabrics (twill, sateen, flannel, denim, tweed) are sewn with 0-60 thread and the stitch should be 3. 4 mm.
Sewing Up Section 3. Basic sewing techniques
Getting StartedLift the presser foot and position the fabric underneath the foot.Lower the needle into the fabric.Lower the presser foot and move the threads to the back.Press foot pedal.
NOTE: When sewing with the buttonhole foot, take the thread to the left.To secure the start of the stitching, reverse a few stitches and then continue stitching forward.
When sewing lightweight or thin fabrics, the straight stitch may be visually slanted.
Stop the machine, turn the handwheel toward you, and lower the needle into the fabric.Raise presser foot.Rotate the fabric around the needle and change the stitching direction as desired. Lower the presser foot and continue sewing.
Press the reverse button and sew a few reverse stitches at the end of the stitch to secure the stitching.
Raise the presser foot and remove the fabric by pulling the threads to the back.
Bring the threads up to the thread cutter. Cut it long enough to start a new seam.
