SOURCE: Consew 206RB, threading problem?

This machine has a safety clutch which is designed to protect the hook mechanism.To access it, place the machine on it's back. About 8-10 inches from the right side you will see an assembly on the main shaft. You need to hold this assembly with a push button located on the bed of the machine while you turn the handwheel. It will click in place when it is in the correct position. Once you've done this the machine should be back in time so it will sew.Hold the top thread ,turn the handwheel and draw the bottom thread up before you begin sewing. Place a piece of fabric under the foot , turn the wheel by hand to make sure there is no binding and that the thread is being picked up.

SOURCE: Upper thread wraps around bobbin mechanism, while sewing

IT PROBABLY IS THREADED INCORRECTLY. GO SLOWLY BY THE DIAPHRAGM AND MAKE SURE IT IS THREADED CORRECTLY. ALSO MAKE SURE SPOOL PIN HOLDERS ARE IN PLACE THAT HELPS TO GUIDE THE THREAD CORRECTLY.

SOURCE: Upper thread knots up with bobbin thread when sewing a stich

Thread test
Test your thread quality to start, thread your machine and LIFT the presser foot (this opens the tension disks). Pull your top thread straight back. If you feel no tension no mater how much thread you pull, your thread is good. If that your machine passes that test, then let me know, we can go to step 2. If not, try different spool of thread, same test until you get a smooth pull (tip: always check your thread this way when you thread your machine)
Step 2:
Pull on your threaded bobbin thread while it’s in the machine. Does it pull smooth and even? If so, go to step 3. If not, try a new bobbin (bobbins get bent or distorted if wound too tight).
Clean thoroughly in the hook and bobbin case area and oil 1-2 drop is all.
Thread knotting on the bobbin can be a lot of things but here's some guidance:
Tension:
If the thread is loose on the bottom of the fabric, it's actually the top thread is too loose. Think of 2 little elves playing tug of war in your machine, one on toip and one underneath. If you have loops on bottom, the top needs to pull harder (tighten top tension)
Jamming bobbin case:
If it is damaged from turning out of place once, it could have rough spots on it that makes the thread hang on it, and keeps making it turn over and over. Use a finger nail board (fine sanding) and smoothall rough spots. Then reset the bobbin case taking care to put the notch in the bobbin case in alignment with the proper spot in the machine (basically 5 o’clock) when looking at the round area where the bobbin case goes.

The bobbin won't spin and I can't thread from the needle


1. Check the tension of the bobbin and adjust. Remove the bobbin case and clean the race (little ditch the case rides on). A qtip works good for cleaning the race. Place one drop of oil on race and replace the bobbin case.
2. Replace the needle and make sure the needle is all the way up in the needle arm. When threading the top, do it with the pressure foot up. As you are threading give little tugs to check for snags. Any snags must be fixed.
3. With hand rotate the hand wheel towards yourself while holding the upper thread to the back of the machine.
IT SHOULD RISE FROM THE BOBBIN NOW. IF NOT IT WILL PROBABLY NEED TIMED.

How do I set a straight stitch? What is causing the top thread to break?


You do not say which machine you have. As for a straight stitch, make sure the needle is central and not in zig zag mode.
The thread can break for several reasons, such as. Incorrect tension.
:Wrong thread for the material.
: Thread in bobbin different from the top thread.
:Old thread.
: Not threaded correctly.
: Needle not inserted correctly, or incorrect needle.or the thread could be wound around the spool holder pin,
Try removing the spool and turn it around.
Hope this helps.

Would like to get a owners manual for my husqvarna 190 selectronic sewing machine. I am having trouble with upper tension and need to make sure I am threading it properly, any suggestions


Here's an ebay that has one for $ 15.00. There are others.

http://www.ebay.com/itm/Vintage-Viking-Husqvarna-Sewing-Machine-Operation-Manual-Optima-190-180-150-/191517822256?pt=LH_DefaultDomain_0&hash=item2c975a0d30

Generic threading:
START TO THREAD WITH PRESSURE FOOT UP. AS YOU THREAD GIVE LITTLE PULLS TO INSURE THERE ARE NO SNAGS.
1. Go from right to left.
2. As you feed you will come to the tension. Make sure it is fed through the tension disc or it won't work.
3. Feed through the take up lever.
4. Feed through the final holes to the needle. Final little pull to check for snags.
5. Put pressure foot down and give little tug. It should have some resistance, but not excessive. Usually four on the tension control is a good starting point.
6. Check your bobbin for pressure. Pull out the bobbin case and let it hang from your finger with the bobbin inserted. While you bob it back and forth it should extend one inch. Adjust the tension as you need to. Put one drop on the little ring under the case. (It looks like a race track).
7. As you use the machine you may have to adjust the upper tension as you need.

Model 9600..thread keeps knotting up on bottom


Check the upper tension discs for lint: Raise the presser foot to open up the discs and blow or 'floss' between them. Any lint or thread in there will prevent them from giving the proper tension.

If that does not work then you may have a damaged hook and/or bobbin case that is snagging the thread. There are a few other reasons also, but you probably need to have it serviced to fix.

Good luck!

How do i fix the problem of my top thread tangling up and moving the bobbin case?


Remove your bobbin case and inspect it for any damage. Scratches, holes, snags. Sometimes you can Dremmel the snags.

Why does the top thread break on my sewing machine?


There are several reasons.

1. The thread spool slit that you put the thread through to keep the spool from unwinding when it\'s not being used could be catching the thread as it unwinds. Check to be sure that the thread can be pulled from the spool without snagging.

2. One of the guides that the thread goes through may have a rough edge, or, more likely, is covered in thread lint and gunk, causing the thread to be pulled. It doesn\'t take much to snag thread. Use a q-tip and alochol, clean all of the threading points on the machine.

3. The tensioner is another possible hang up. Make sure that the tension is not too tight for the type of thread or fabric that you are using.

4. The needle may have a burr or rough spot on it. Replace the needle to see if the problem continues.

5. The bobbin case is the last place of concern. there may be a lot of thread lint, or the bobbin case is not seated properly. Sometimes, the thread hood under the bobbin case needs cleaning. Following the cleaning instructions in your manual, remove the bobbin case and thoroughly clean in there.

6. Finally, check in your manual to see if anything need oiling.

Bobbin case problems are common, and usually bobbin race parts are easy to find and not too expensive if you need to completely replace them. Otherwise I have successfully sanded down burrs on cases and races if that is what the thread is snagging on... ? Without having someone look at how it is snagging, it is hard to diagnose. Hope you figure it out!

Question about a bobbin


First you have to determine if the thread under the plate is the bobbin's thread... or just great loops from the upper thread.

Bobbin snarls are caused by the bobbin unspooling in the wrong direction.

Burrs and snags on the carrier.

Upper thread snarls in the bobbin area are "operator error" Typically, upper thread not threaded correctly (foot UP, buttercup)... or neglecting to put the presserfoot down while sewing.

Good luck.

I have a brother ls-2125 sewing machine. the upper thread is not catching the bobbin thread properly. help please


  1. Tension
    • Your sewing machine tension controls the rate at which the thread is fed through either the upper section of your machine or through the bobbin case. If your upper or bobbin threads aren't threading properly, sometimes adjusting the tension will correct this problem.
    Timing
    • Your sewing machine works by passing the upper thread through the needle of the sewing machine at precisely the same time the bobbin brings its thread to its uppermost position. If either the needle or the bobbin thread reach these positions too soon or too late, the threads won't interact and create the knots that make the seam. You can throw off your timing by sewing too many layers of fabric or hitting a pin with your needle. See you sewing machine repair facility to correct any timing issues.
    Thread
    • Thread can get snagged or caught in the upper section of your machine or on lint pieces in the lower bobbin section. If your threads aren't catching properly, you may be able to fix it by unthreading and rethreading both your upper thread and bobbin threads.

Thread on bobbin looping


Sounds like you need to adjust the bobbin casing tension (tighten the little screw on the bobbin case). I would also oil the face of the bobbin casing so that the thread wont snag or tug on it at all.
