How to Identify and Fix Common Vacuum Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :
The Problem: Stitches are coming out uneven or skipping entirely. THE SOLUTION: Odds are, the secret culprit here is a needle that is broken, bent, or otherwise damaged. Experts recommend that you replace your needles every 16 hours of stitching time.
A: Looping on the underside, or back of the fabric, means the top tension is too loose compared to the bobbin tension, so the bobbin thread is pulling too much top thread underneath. By tightening the top tension, the loops will stop, but the added tension may cause breakage, especially with sensitive threads.
Looped stitches are usually caused by improper tension. If the loop is on the upper side, it may be corrected by loosening the top tension or by tightening the lower tension. If the loop is on the under side, it is usually best corrected by adjusting the upper tension.
A blunt or damaged needle is the number one culprit for poor stitch quality and can lead to any number of stitch problems, including skipped and uneven stitches and thread shredding.
Probable Causes: – Top or bobbin thread is not set correctly. – Thread does not match the needle. – Thread tension setting is not properly set.
Thread loops are used for invisible fastenings and are used in conjunction with metal hooks for delicate trims and closures. You can find them throughout the 19th Century on Regency and Romantic era dresses and especially on late Victorian and Edwardian bodices and gowns.
With reverse stitches, the stitching is sewn in the opposite direction. When any of the following stitches is selected, pressing. (Reverse/Reinforcement stitch button) will sew reverse stitches.
The standard tension is 4. Janome recommends a range of 2 – 6 for straight stitches.
Recognizing balanced tensions
The easiest way to spot unbalanced tension is to look for visible knots or loops at the end of each stitch. When the bobbin thread shows on the right side, the needle tension is too tight or the bobbin thread, too loose, as shown at left in the illustration below.
Unbalance stitch
If the interlacement of threads does not take place in the middle (i.e. if the interlacement is taken place in the upper or lower position from the middle) of two layers of fabrics then it is known as an unbalanced stitch.
Many factors affect the level of seam strength. These are fabric structure and properties, stress location of a garment, sewing thread type and construction, sewing machine tension, sewing needle type, stitch and seam types and stitch density [12].
While stitching thick fabric, such as denim or leather, a tension of 3.5 to 4.5 is recommended. This is to sew through the fabric and maintain neatness throughout easily.
Typically, the Jasmine Stitch is considered by crocheters to be the hardest stitch to learn. It is certainly a beautiful stitch, but it uses a very unconventional technique that doesn`t always come naturally to people.
The Varley loop method determines the distance to the fault without knowing the length of either the faulted or unfaulted conductor if the resistance per unit length of the faulted conductor is known. From: Power System Fault Diagnosis, 2022.
There are basically two types of Loops in most computer Programming languages, namely, entry controlled Loops and exit controlled Loops.
So we`ll be talking only about the top thread tension since that`s where you`d usually make the adjustments. The dial settings run from 0 to 9, so 4.5 is generally the `default` position for normal straight-stitch sewing. This should be suitable for most fabrics.
A correct thread tension looks smooth and flat on both sides of the seam. The needle and bobbin threads interlock midway between the surfaces of the material.
Bobbin tensions should be 18 to 22 grams (up to 25 grams when embroidering caps). Proper tensions for satin stitches should reveal 1/3 bobbin and 2/3 top thread color on the underside of the embroidery as seen on the image above. A clean bobbin case is essential for proper tension settings.
Complications of suturing
Sutures must not be too tight, as this can lead to devitalisation of the tissue at the wound edge. They must also not be too loose, as this can lead to inadequate apposition of the wound edges, resulting in delayed healing and a poor cosmetic result.
It may sound banal, but particularly when you sew thick fabrics or several layers, you might forget to lower the presser foot. This of course means that there is no tension on the upper thread. The upper thread is pulled under, resulting in thread bunching.
If the upper thread is incorrectly threaded, the upper thread passed through the fabric cannot be firmly pulled up and the upper thread becomes tangled in the bobbin case, causing a rattling noise.
Your Backstitch Lever Is Jammed
If a loose thread has gotten inside your machine, it can wrap around your backstitch lever and prevent your sewing machine from sewing forward. This is rare, but it`s possible for both thread and lint to jam your reverse-stitching mechanism.
Article Talk. Backstitch or back stitch and its variants stem stitch, outline stitch and split stitch are a class of embroidery and sewing stitches in which individual stitches are made backward to the general direction of sewing.
Your Stitch Is Set to Automatic Lockstitch
You won`t be able to sew in reverse if you`ve selected the automatic lockstitch option. Select a regular stitch and this should fix the problem.

ANSWER : Totally rethread your machine, if the underneath threads are looping it is your threading on top that is causing the problem. Make sure that you thread is not tangled.

.I have this machine. I use it for my heavy sewing, as it will go through anything. I would be happy to copy the manual and send it to you for copy costs. Just let me know. I would love to know what knowledge you have gained about this machine. It does not appear to be an easy machine to find info on, may not have produced a lot? I had no idea it was not a European produced machine.

Have a 3 year old Pfaff Creative Vision. Has less than 14 total sewing hours on it. Has had issues in the past. Breaking needles, wouldn’t stitch out designs in acceptable manner(badly distorted looking) breaking needles repeated, now it is changes stitches on its own, then went to sewing the same stitch but isn’t sewing it consistantly. I have taken it back to the same professional to repair each time. Can thhis machine be repaired??? Should I trade it off and get another, this isn’t my first c
ANSWER : It sounds like this machine has some kind of fault in it for sure. It can be repaired again, but will likely need to be repaired again after that – down the road. Personally I recommend you just get rid of this unit and go for a different model. You can sell it on ebay to at least get something out of it. Just list it as accurately as you can, naming this issue.
Thanks

Our beautiful Bernina 730 sewing machine has been stored in the garage in its original case, and that wrapped in plastic, for a few years now. Temperatures have been both hot and cold in the garage, but the environment was dust-free.
We have brought the Bernina in, set it up, oiled it as specified in the manual, with the original sewing machine oil. We have correctly threaded the machine and the bobbin thread is up.
When we press on the pedal to sew, the machine gets electricity and buzzes
ANSWER : Hello and thank you for using Fixya ….
From what you describe there can be only 2 causes…Either the machine is still stuck ..and the motor buzzes cause it can not spin it ..and in this case it needs to be oiled more..and be spun by hand until it moves well and free…and after that it will work ..or during the storage ..from condense or so ..the motor is stuck ..and needs to be checked…In this second case ..it probably need to be oiled too (the motor ) ..and the coils changed..
Have a nice day ..!

I have an old kenmore sewing machine. When i run fabric through, the bottom stitching turns into a total rats nest. Its as if the bottom is pulling a ton of thread for each stitch. The top stitching looks fine. Not sure what to do and i am a total beginner at sewing! thanks
ANSWER : Check the tension on the bobbin thread and ensure that the bobbin is in the right way, the thread must double back on itself.

Borrowed Brother XR7700 Sewing Machine
1st: Sewed one inch OK; moved fabric and it stopped sewing, motor made thudding noise. When push-button (NOT pedal) is used, gives error E6,
consistent with motor noise.
2d: In order to check threading had to manually PULL bobbin case toward me or it was UNDER needle plate. Cleaned a fair amount of dust out. Reinstalled bobbin, etc., per manual, rethreaded.
3rd: Will sew 2-3 stitches, then packs up again just like in 1st instance above. Have st
ANSWER : Have you checked your needle. it could probably be bent somehow. you should replace it first because that also can confuse the sensor causing that error.

I bought this machine about 3 years ago but hadn’t used it due to illness. Now when I tried to sew with the Tuff Sew ,the threads continually break. If I can make about a 3 inch line of staight stitches without the top thread breaking,I consider myself fortunate The direction in the manual are extremely poor. I had to finish my project with my very old Bernina. I regret buying the Tuff Sew straight stitch. JLWebb
ANSWER : I do not have one but these machines require heavy duty thread…
.
.The manufacture recommends using only “#69 Bonded Nylon Thread”
.
.You should have a 18 to 20 gauge needle for that size thread. Needle type is 135×17
.
.To be completely honest, these machines look like they are 20 to 30-year-old designs meant to be “store branded” machines (Woolworth, K-mart, Sears, …). As demand at these types of stores dried up, they may have tried (successfully) to remarket them as “tuff” machines. Almost all older machines used all metal gears – it doesn’t make them tough or high quality. The poor level of technical support and documentation would upset me too.
.
.I really hope the recommended thread and needle help with your problem.
.
.Good luck.

My Singer Sewing machine (model 6215) is now only sewing in reverse. After pressing the backstitch button, the button seemed to stick in the backstitch position. I was finally able to pull the button out but my machine continues to only stitch backwards. What do I do now?
ANSWER : It’s stuck inside. Open it up so you can see inside the bottom, look for the feed dog mechanism and you’ll find where length of step is varied, this is where the reversing takes place too. Tapping gently and oiling will free it up.
