What to do if your sewing machine skips stitches?
No matter how reliable and modern would be your sewing machine, 100% avoid errors of work and breakdowns will not work. However, in addition to unforeseen complex breakdowns, there are also quite typical malfunctions that almost any craftswoman encounters. One of these problems is skipping stitches without obvious visible signs of damage to the sewing machine. This does not always mean that you need to urgently contact the repair service. we will tell you why the sewing machine skips stitches, what to do in such a situation and how to overcome the problem with minimal hassle.
Determining the root cause of skipped stitches is easier if you understand the principle of shuttle stitch formation. A stitch is formed because the hook takes a loop off the needle while it is moving. Once the shuttle wraps around the upper thread, a strong stitch is formed, and both threads firmly bind the fabric on both sides. You will not see skipped stitches if the hook and needle point interact as they should. That’s why the first thing to do in this situation is to check that the hook and needle are correctly adjusted. As a rule, the gap between them should not exceed 3 mm. With a larger gap, the hook will pass far from the needle and will not catch the thread. A magnifying glass will help you determine how accurately the machine is set up. You can make adjustments to the gap yourself. But be careful, too little gap can cause your needle to break or your blade to dull. If you are unsure, you can call a craftsman to fine-tune the gap. NOTE! Before you begin to adjust the gap, make sure that the thread tension is correct, and that the quality, needle grade, and thread number match the thickness of the fabric being worked.
Why the sewing machine skips stitches.Surely with this p
Probably everyone, who uses a sewing machine more or less regularly, has faced this problem at least once. Here it would seem and the correctness of the charging checked, and the needle changed, and the hook device cleaned, but the machine still skips stitches! Why this happens and what to do in this case?
Let’s try to find the cause of skipped stitches when using a sewing machine. The problem in most cases looks like this: the thread lowered by the needle down, not picked up by the hook spout, that is, as a result of any violations of the machine can not form a big enough loop, which could capture the hook spout, and, consequently, the stitch is not obtained. Let’s look at what kind of faults can cause skipped stitches? Why?
First, a good reason for skipped stitches can be a needle that is not suitable for the type of work performed, the type of material, or in the end just bent or blunted. For example, if a needle that is too thick gets caught in a thread, it pulls it down, creating a loop that prevents the upper thread from looping.
Second, the sewing machine can skip stitches because the sewing threads do not match the type and number of the needle. For example, a thin needle and thick upper thread can create a loop on the opposite side of the needle where it cannot be picked up by the hook nose.
Third, the sewing machine often skips stitches when sewing stretchy synthetic fabrics. If the fabric you are working with is stretchy, a thin needle will not be able to make a sufficient hole in it. As the needle passes through the hole in the needle plate, the fabric clings to it.
Fourth, skipped stitches are often caused by moving from a thick to a thin seam (for example, sewing the bottoms of pant legs in jeans).
Fifth, skipped stitches can be caused by misalignment between the hook and needle.
If your sewing machine has started to skip stitches, proceed as follows:
Check that the upper and lower threads are correctly threaded.2. Relax the tension of the upper thread.3. Change a needle. An old needle can get dull, bent or dirty over time. In doing so, it is important to know what type of needle your machine is set up for. All needles are labeled with a caliber, so check the sewing machine manual for the recommended needle size so you can find the one that is right for you.
When purchasing needles, choose the smallest appropriate needle thickness for the particular fabric. It is preferable to use a universal needle, or a needle with a medium or wide circular point, or a finishing stitch needle. When sewing stretch fabrics, use needles that are specifically designed for stretch fabrics. Insert the needle correctly into the needle clamp. But in especially difficult cases, it can be lowered a little, sometimes this method helps so that a large enough loop of the upper thread can be formed.
Check if the presser foot is level, sometimes you need to increase its pressure (or even pull the nose of the foot down when sewing), which will result in it will hold the fabric much better. In this case, the needle will not pull the fabric down through the needle plate. Preferably use a straight stitch foot (with a small round hole). If you do not have a straight stitch foot, try moving the needle to the far right position.
Use a needle plate with a small hole, if you do not have a needle plate with a small hole, try taping part of the wide hole on the regular needle plate with duct tape.
Change the sewing threads. Probably the threads you use have a higher twist. Because of the heavily twisted thread, the buttonhole may immediately fold to the side when formed, resulting in a skipped stitch.
When sewing stretchy synthetic fabrics, you can try stabilizing the fabric with a special water-soluble material, if this is not available, soak the fabric in a solution of gelatin or starch. Thin paper can be placed under the fabric and torn off gently when sewing is complete.
When moving from a thick to a thin section of seam, use a special device-foot for passing thick places. Some sewing machines have a mechanism that makes it easy to switch from thin to thicker material. read your sewing machine’s manual carefully.
If none of these methods helped you, perhaps your sewing machine skips stitches due to misalignment of the movement of the hook and needle. In this case, the best way to fix the problem is to call a sewing machine repairman. If you’re ready to learn all the secrets of sewing machine repair yourself, you can help with the book A.И. Zyuzina “Repair of sewing machines”.
The main reasons for omissions
Although to correct the work of a sewing machine with skipped stitches quickly and efficiently can in a workshop that specializes in the repair of similar equipment, the simplest steps in finding the fault the user makes and independently. The most common causes of skipped stitches are similar in all generations of sewing machines, whether they are “Singer” or modern models, including Chinese ones.
If we are talking about stitching by zigzag type, the first thing to check whether the needle is not bent and blunt. “Professional disease” is typical for beginners who forget to change the needle when switching, for example, from fleece to tarpaulin. If the needle is so blunt that it is not able to pierce the fabric without tearing it at the point of the hole, and if it may have microcracks. change it immediately.
A “wrong” needle when sewing on this or that material is the result of forgetfulness or inexperience of the novice worker. Despite the marking, many needle sizes are remarkably similar in appearance. Knitwear needles, for instance, are somewhat blunted. They do not pierce and do not damage the neighboring fibers of the fabric, but spread them apart. Attempting to use a needle that is too sharp can squash individual fibers, near the seam the fabric will wear out faster and cause stretching.
Each needle has a seating bulb that is inserted into the clamp of the reciprocating “foot”. If a circular needle is inserted into this clamp instead of a cut needle (or vice versa), the “aiming” in the gap where it goes when making each stitch will change somewhat. In general, the mechanism will not work with the accuracy for which it was originally designed.
- At best the machine will sew inaccurately. Stitches will be crooked, displaced by the same vector.
- often the machine will skip stitches. singly or in groups.
- If a needle hits the presser foot or hook, it will be broken right away, and the mechanism of cheap machines, not being very powerful, will be noticeably damaged.
Manufacturer specifies in the manual and on the body of the machine needle size. if the machine is not designed for sewing thick fabrics. Most machines are equipped with a double stapler, not a single one (as most ultra-compact and portable). The upper thread in them is fed from the bobbin or spool from above, the lower. from the spool or bobbin below, hidden under the presser foot. Thin thread should not be threaded into a thick needle. It should not be too stiff. like Soviet cotton thread.
It is better to use, for example, kapron variant, which preserves the integrity of the weave, not getting soaked when passing through the needle. Also, the thread must not be twisted from the factory. otherwise it easily forms twists that prevent the hook from properly forming a loop. The ideal, in the opinion of consumers, thread should be smooth, not twisted, strong enough and at the same time elastic.
In the case of nylon threads can be difficult: sewing inelastic fabrics can lead to skipped stitches and break the newly created seam (before pulling the fabric out from under the presser of the machine).
Over-expanded needle plate hole. a “disease” of machines that have been used for generations. A broken hole does not allow the needle to pass through the fabric properly. it crumples into it, and the stitching loop does not always form, or does not form at all. Poor movement of the fabric under the presser parts can cause both skipped stitches and overlapping stitches, resulting in an interwoven seam. A more complicated version. the lower layers of fabric move faster than the upper, so the latter wrinkle, stitching gets a prohibitive curvature.
Several types of fabric (leather and leatherette, nubuck, suede, corduroy, velvet) cannot move freely initially. To help with the advancement of any of these types of material using a special foot with extra rollers, pushing these materials with a force noticeable. Inserting another Teflon-coated presser foot will allow you to pull through all the multiple layers to be stitched into one. In a domestic sewing machine, “difficult” fabric is poorly handled. this is what industrial, professional machines are for, which use much more powerful mechanics, more massive needles and thicker kapron as thread.
Excessive sliding fabric also causes skipped stitches. Gaining more speed than designed, it does not allow the hook and needle to make the standard length of the stitch. Uneven sliding can completely ruin a seam. All machines have spring loaded brackets that ensure the tension of the upper thread. An overtightened tensioner, in which the thread runs with a noticeable force, leads to skipped stitches.
Why the sewing machine skips stitches Disclosing the problem.
Even the best sewing machines break. In the case where the sewing machine does not sew a straight stitch and skips stitches and stitched stitches dissolve, it suggests that the settings are confused, and maybe there was damage to the machine.
Often the fault of the damage can be determined in person by carefully reading the instructions. But still try to repair the sewing machine yourself is not worth it, if you do not want to make worse, breaking some detail.Similar problems can occur with domestic sewing machines, as well as with industrial sewing machines, although there is a real dissimilarity: a defect in even one industrial machine affects the entire production process
Therefore, in these cases, it is important to adjust the sewing machine in time
Typically, sewing machine malfunctions are that it does not accurately perform its functions: broken needle, thread breaks, stitches are crooked. The culprit is several factors:
Using needles that are not designed for a particular type of sewing machine. The needle may not match the thickness of the thread or the density of the material. As a result, the needle will either break or bend. In this case, you need to choose the right needles for your sewing machine. A particular type of needle needs a particular thickness of thread, when this proportion is not chosen correctly, the stitches will come out not particularly tight or the needle will break. Broken needle plate. When plate faults are weightless, then it is realistic to limit the grinding of the needle plate window. When the failure is more significant, you will need to change the needle plate. Broken settings of the mechanism that lowers and raises the needle and moves the thread retractor. Exactly align the mechanism itself is quite difficult, because it is through the shafts associated with the shuttle mechanism. The smallest discrepancy with the settings will cause problems with the sewing machine. Damaged shuttle socket. When the hook socket breaks, the machine will not sew as the thread will tear all the time.
Another group of common breakdowns is related to motor breakdowns in electric sewing machines. They pop up when the sewing machine does not turn on or the motor does not work, you can also hear the smell of burning. The main culprits of motor failure:
Broken wires Breakage of motor winding Damage of packer
Automatic machines break down at electronic sewing machines. This breakdown is seen when: the motor does not start, the machine does not work, and there is no smell of burning. The most popular causes:
Breakage of the computer built into the sewing machine Breakage of the sewing machine control
Parts should be replaced in these situations.
High angle of buttonhole deflection
The desired stitch loop is formed on the back side of the hook. A higher angle increases the chance of missing a stitch, as well as too small a buttonhole. What to do in this situation? Try to give the needle bar the right angle, acting carefully so as not to damage the machine. You can also rework the part by sawing a new flat on it. Choose an angle that is appropriate for your machine, and perform the necessary procedure.
Like any mechanism, the sewing machine is subject to a variety of breakdowns, but for devices of this type there are typical and most common cases. For example, why a sewing machine skips stitches when sewing? To answer this question, you need to look inside the machine and know how it functions.
A bent or blunt needle causes skipped stitches
A bent needle also causes skipped stitches on the sewing machine. The slightest warp, dullness of the needle should be replaced. Never trying to straighten the needle or sharpen it. Sewing needle metal is a special grade and cannot be perfectly straightened. Make it a habit to change needles more often, even if it is not strictly necessary. This is especially important after prolonged use of it or when there is a deafening knock. This sound means that the “dull” spout of the needle is no longer piercing, and breaks through the fabric, and that is why the characteristic sound appears.
What to do if the sewing machine skips stitches
The first thing to do if you are faced with such a problem is to determine the cause. For example, if it is about a broken plate, then there is only one way out. you will have to replace it.
But if the machine is externally intact, make sure the quality of the sewing needle, the correct distance in the gap and the quality of the threads.
Get into the habit of changing a needle in time, before it is completely blunted. That way, you can prevent many problems.
So, the first action is to check the needle. Beginners confuse household and professional needles, as they look very similar. But a household needle has a needle which is sawn off on one side, while a professional needle is round. Different cutting depth, thickness and length of the needle, all affect the distance between the needle and the hook and the quality of the seam. Only use needles that the manufacturer offers. Any sewing machine comes with a manual, you can take it with you to the store to make the right choice.
Don’t forget that the quality of the seam also depends on the threads. There are too twisted threads, they are thin and immediately form knots, because of which the hook can not catch them.
If the needle is new, fits your type of machine and the fabric you are sewing, you are using good threads, then check the clearance between the hook nose and the eyelet. For knitwear, the gap should be 1 mm, for heavy fabrics 1-1.2 mm. At most, a gap of 3 mm is acceptable when working with specific fabrics. To fix the problem, you will need a magnifying glass and strict adherence to the following steps:
- Set the machine to “straight stitch” mode.
- Remove the needle plate and presser foot.
- Lower the needle bar to the maximum position.
- Now gently raise the needle by 2 mm, with the hook hook nose 1.5-2 mm higher than the eye, and the distance between them should be no more than 0.3 mm.
If the gap is too big or too small, you need to adjust it, because the spout can’t pick up the thread, and skipped stitches occur. If in doubt, it is better to entrust the work to a professional in the service center, contacting the online sewing machine store “Daddy”.
