The sewing machine does not stitch, does not sew, does not sew
Starting to sew on the sewing machine, you need to check its readiness for work, as well as make a small test stitch on a small flap. This applies to all brands. both domestic, like Chayka, Aurora or Podolsk, and imported. Siruba, Merrylock and AstraLux (Taiwan), Brother, Janome, Juki and Jaguar (Japan), Veritas, Pfaff, Husqvarna, Elna, Bernina (Europe), Singer (USA). It happens that the originally working perfectly sewing machine, begins to mix up the threads, and therefore the stitches are uneven, and in this case the sewing of high-quality products is not possible. In most cases, you can fix minor malfunctions resulting from improper settings yourself, but sometimes you may need the help of a qualified sewing machine repairman.

Preliminary tension check
In addition to the settings of the sewing machine, a number of factors can affect the thread tension. Before you start turning the tensioner wheel right away, check other possible causes.
Sewing machine will not stitch
Is the needle bent?? Is there a burr on the needle tip?
Is the needle size is appropriate for the fabric?
Check if the machine is correctly primed?
Most machines are equipped with thread guides, tension rollers, and tension regulators. The bobbin case spring affects the bobbin thread tension. So first make sure that the machine is correctly primed. Remember that in most machines, the tension rollers are closed when the presser foot is lowered, so be sure to thread the machine with the presser foot raised. A good habit. tuck in the thread and pull out 50 cm of thread. Holding the floss firmly with your hand, without tucking it in, so that the floss “snaps” into the tension rollers (like flossing your teeth). This ensures that the floss is positioned correctly in the tensioner.
Is the thread density in the top bobbin and bobbin the same? Good quality thread?
Is the upper thread not catching the notch or rough surface on the edge of the spool of thread?
Have you dropped the metal spool on a hard floor? If this has happened, an almost imperceptible damage can prevent proper operation.
Whether the idler rollers are clean? Sometimes lint accumulates on the rollers. Fill the machine as usual. Remove the thread from the spool and cut it near the spool.
Tie two or three knots on the thread from above and make sure they are tight.
Pull the knotted thread through the tension rollers down to the needle. Tiny knots often catch the lint on the idlers. Don’t forget to close the machine between uses to keep dust out.
Using the “Stop” function
The method is good if you are working on a modern machine with many options. There is usually a “stop” button on these devices. Press it before you start sewing, then the machine will make a discreet knot.
Of course, the seam will not hold if the knot is not tied. But there are times when you’ve secured the ends, but the stitching is still loose. Why does this happen?? There are two reasons for this:
It is not difficult to solve this problem. It’s best to secure the stitch to the machine (it’s neat that way). If you can’t access the machine, you can take some fine, color-matched thread, a small needle, and sew up the loose edges by hand. The key is to make small stitches and take your time when tying new knots.
Headache : How skipping stitches can ruin my life
Skipping stitches means that the upper thread is not engaging with the lower thread. The method of deduction, Watson.
Why Do Sewing Machines Do This /Upper and lower bad stitches problem and solution/Sewing Problem
First question: Does the fabric match the needle?? Common mistake. For example, if you are sewing knitwear, you need to use a jersey needle.
You are trying to sew a thick fabric? The solution could also be to use the right needle. There is usually a fabric and thread matching chart in your sewing machine manual.
Missing stitches are usually due to the tension we just talked about. So, again, don’t panic, just check on a piece of fabric how your upper and lower threads are in sync.
Here are some quick fixes for the problem:
- Change the needle;
- Re-insert the machine;
- Re-thread the bobbin (the thread is probably tangled in it);
- Slightly decrease or increase the stitch length of the sewing machine;
- slightly increase or decrease the tension of the upper thread;
- Allow the comb to move the fabric by itself, do not pull on the edge of the fabric;
- slow down the speed of the sewing machine. Sewing. This is not a race, and fast sewing can make it difficult to hook the bobbin or cause the needles to bend or break.
This last point brings me to my next problem.
Ways to fix it
These problems are solved in different ways. In some cases you can cope by yourself, but there are situations where the machine has to give a professional craftsman.
So, if the thread does not yield, too tight or, on the contrary, weak, you can check whether the bobbin is properly installed. The thread tension can be monitored and readjusted with a special screw (located next to the hook mechanism). After troubleshooting it is recommended to make a test stitch to check the performance of the machine.
If the angle piece is tapered, moved to the side, it is recommended to check the thread tension. It should not be too tight.
When the bobbin thread is not picking up, and the line is intermittent, check the hook. It may need to be cleaned from winding threads. Another possibility of a faulty hook is manifested by sagging loops on the inside. This means that you need to replace the hook or its individual elements (some parts can oxidize, wear).
The needle should be replaced if the fabric begins to jam under the bottom panel. The needle is probably dull or bent.
If the machine stopped working and does not turn on at all, it will have to carry it to repair. It may not be that bad, and a craftsman can reanimate it quickly enough.
Causes of skipped stitches
If your machine is skipping stitches, start looking for the cause by following the “simple to complex” principle.
The first thing to check is these factors:
- Thread tension. This parameter can be affected by errors in threading, as well as contamination of the device. Check and adjust this parameter in the way indicated in the manual.
- Type of needle. The domestic sewing machine may have had an industrial type needle installed, with a round bulb, or another that does not match your machine. The wrong needle can not work with the hook, and skips will occur as a result. Be sure to check the marking of the needle, it must coincide with that specified in the instructions for the machine.
- The needle may be bent or blunted. Put a new one in and check the stitching, maybe the problem of skipped stitches will be solved. Many craftsmen recommend changing the needle after sewing 2-3 products, and the changed sound when piercing the fabric is a clear signal of the need for such replacement.
- Needle and fabric match. Sewing with knitwear, denim or leather requires the use of special needles. Attempting to sew difficult materials with a universal needle can cause poor stitching.
- Needle and thread combination. Thick thread in a thin needle when sewing can lead to loops in the fabric exit and therefore to skipped stitches.
- Low quality threads can also cause a problem. Twisted thread forms knots, leads to incorrect loop formation and the hook nose cannot pick it up. When sewing, use quality threads that are of uniform thickness and without much twist, matching their size to the needle and fabric being used.
- Damaged needle plate. A “broken” hole in the plate pulls fabric inside, which prevents the thread from moving freely and forming the necessary loop. In this case only a complete replacement of the needle plate can help.
If you have checked all of these causes, and the machine is still showing incorrect stitching, you need to check the clearance between the ear and the hook spout. This is easier to do with a magnifying glass.
- Set the “straight stitch” operation.
- Remove the needle plate and presser foot.
- Lower the needle gun as much as possible. Raise the needle by 1,8-2 mm. At this point, the spout of the shuttle should be higher than the ear by 1.1-2 mm, and the distance between them (gap) should be 0.15 to 0.25 mm. The maximum allowable value. 0.3 mm, a larger figure will not give the spout to capture the loop of the upper thread.
If you’re convinced you have the wrong clearance values, mechanical adjustments to the equipment will be needed. We recommend that such work should be entrusted to a professional, especially if the machine is under warranty service.
The above causes will help you find out why your sewing machine started skipping stitches when sewing. Check needle, thread, and tension settings before use, and remember to periodically clean the machine of debris.
The basic principles of the formation of stitches
In order to understand why the sewing machine does not sew, no stitches, it is necessary to explain how the process of stitch formation. Intertwining of the upper and lower thread to form a stitch occurs during the simultaneous operation of two parts. needle and hook. This occurs according to the following pattern:
- The needle through the fabric is lowered to the hook.
- The bow part of the hook comes almost close to the needle (normal gap should be 0.1-0.3 mm).
- The needle is pulled off the trigger loop on the hook.
- Wraps the loop around itself.
- The needle rises, pulling the loop.
- The stitch is formed.
The main point in this scheme is the close proximity of the hook tip and the needle point. Very often in cases of skipped stitches this distance is violated. It is often a gap of more than 1 mm. Thread pick-up is not possible in this case.
Faulty hook or disturbed adjustment
Why does not sew with a manual sewing machine “Podolsk”? This is most likely due to the operation of the shuttle. The quality of these machines often depends on its condition. What could be malfunctions? In the shuttle can get dirty or get wet, then it can be tight, and in some cases even jammed. Because of this does not sew with a manual sewing machine. Why does it happen??
What to do to get a good stitch
The main culprit for a sewing machine not making a stitch is the needle. To fix the situation, you should:
- First, check that the threads are correctly threaded. Many times our craftsmen have had to deal with experienced seamstresses who have incorrectly threaded the upper thread. If you have a lot of experience, still check if the upper thread is threaded in the thread guide. Lint could get tangled between the tensioner plates, which prevents them from closing.
- Choose a straight and sharp needle that will fit the sewing mode.
- When replacing the needle, make sure that the cut on the bulb and its diameter coincided with those recommended by the manufacturer. If you take a different fitting, it may not match in length or not fit in place if the cut of the bulb is different. All of these will interfere with the formation of the seam.
- To avoid squeezing the fabric inside the needle plate, you should adjust the pressure foot that presses the fabric.
- When choosing threads to be guided by the characteristics of the product.
- Do not use poor quality, twisted thread.
- If the needle plate is deformed, replace it.
- If you hem the bottom of the product with a thick edge (for example, jeans), you can use a special foot. Some machines have mechanisms to facilitate the transition from thin to thick.
If you have all of these conditions, but does not sew sewing machine, no stitches, it indicates that the gap between the tip and the nose of the hook device has increased, it is worth seeking help from professionals who can adjust it.
