Question about Sewing Machines

1 Answer

My Singer 648 is having a problem with the bobbin thread getting caught up in the bobbin case and jamming the thread inside the case breaking the thread. Is there a solution to this problem? Thanks

I do have the manual and have followed the instructions for replacing the bobbin. I've sewn on this machine for many years and have never had this problem.

try another bobbin
make sure the bobbin is turned the right way in the bobbin case

SOURCE: unable to replace bobbin case back into machine

Here's how I do it. I hold the thread with my left hand, just like the thread wikk be pulled up. With the right hand pull the metal tab toward me, hold it open while pushing bobbin in and twisting. When bobbin stops turning and feels seated, then release the metal tab to lock. good luck!

SOURCE: replacing the bobbin case

1) Use a strong polyester type thread, NOT FINE COTTON

2) Use a low tension,nuber 2 for exanple

3) Always check the threading, if in doubt rethread all the way
from the top bottom making sure you pass roun and not
through thr fixed holder spring.

4) Make sure the thread moves freely with the tension disc held
to the right while pulling the thread through the needle

5) Be very careful that the thread is pulled up from the lower
bobbin correctly and check there is no muddle or stray
thread under the cover

6 Dont pull on the fabric (not thick for beginning) - just guide it

Try inserting the bobbin in the reverse direction. Most machines take a bobbin clockwise or counterclockwise and it can make a difference. Also try a new needle, a bad needle is often the problem believe it or not.

SOURCE: singer touch and sew 648

Thread the machine as if you were going to sew. When you thread the needle, pull the thread off to the left and wrap it around the thumb screw on the left and just above the needle. Wrap it only 2 or 3 times and hold the end of the thread. With bobbin in place and the face plate slid open, push the thumb lever on the left under the face plate to the left. Begin to 'sew'. As you do, the bobbin will wind and the thread you are holding will detach. Once the bobbin is full to the outside line, slide the face plate the closed position. As it closes, it will release the thumb lever. Put the needle in the slightly lowered position and slide something blunt under the pressure foot pulling thread from both the bobbin and the needle; cut the thread when you've pulled it out sufficiently.

Check needle.
Bent? Replace it!
Always thread needle with presser foot in up position. If presser foot sitting flat against feed dogs when you thread the needle eye, the tension disks will not allow thread to locate itself into tension disks at all, in which case, no matter how much you adjust settings - nothing will do any good UNTIL you thread needle eye with presser foot in up position so tension disks can work.
If you don't think that is problem, then set machine on a straight stitch with straight stitch foot, set tension on 4, stitch with on 4-5, test light to medium woven fabric with size #11 needle to test.
Always clean shuttle and feed dogs for broken thread or lint, and put in new needle before getting panicky.

When I fill the bobbin with thread, it doesn't load evenly and bobbin gets jammed.


When you wind a bobbin, the thread usually goes through a "feeder" which creates a tiny bit of tension and a lot of direction. Make sure you have it through this. It is usually two circular discs, cupped, and back to back.

Sewing machine is jamming on first turn permanently


Your bobbin may be in backwards. Is it possible to put it in either way?

My machine keeps jamming, what happens is that the top thread gets caught in the hook how do i solve this


Be sure there are no thread tails hanging from the bobbin when it's inserted into the bobbin case. They can jam the machine and cause the upper thread to break. And note that there's no such thing as a generic bobbin. Always use a bobbin designed for your machine in order to avoid skipped stitches, loose threads, and noise, as well as permanent damage to the bobbin case.
Clean your bobbin case and open the race (what you insert the bobbin into) to clean that out as well as the feed dogs. Excess lint can cause a lot of trouble when you're sewing so cleaning and oiling often can save you frustration and damage. Also use a quality thread that will not add to the lint build up.
Your race might also have a small burr that needs to be gently rubbed off. Do not use sandpaper as that will cause more burrs to form.
Hope this helped.

I just got a new Singer Simple. I had a problem with the needle thread getting caught in the bobbin shuttle. I disassembled this area, found a random thread, and cleaned it out. I put it all back together...


Do you have the bobbin thread going the right way, according to owners manual some go clock wise some go counter clock wise when you pull the thread after bobbin inserted in bobbin case

When i start to sew, my thread gets caught up on bobbin. the string gets wrapped around the bobbin then breaks the thread. it seems as though the bobbin is sitting a hair too high. ? ? ?


Make sure there is no fluff/lint within the bobbin case causing the bobbin to stand proud. Pressure from the bobbin thread can sometimes stretch the bobbin itself.. replace the bobbin with a brand new one. Double check your threading be removing all thread and starting from scratch.

The thread hangs up inside the bobbin holder


A jammed machine is caused by thread being caught in the hook. Remove the upper thread and the bobbin case, turn the hand wheel towards you (counterclockwise) by hand and remove any thread in the bobbin case area. *Always turn the hand wheel towards you. Turning the hand wheel away from you (clockwise) can cause the machines timing to become unaligned and jam your machine. Also, always make sure the presser foot is in the down position before you start sewing. Sewing with the presser foot in the up position will jam your machine in the bobbin case.

My sewing machine keeps getting jammed when sewing. the top stitch keeps getting tangled in with the bobbin thread and jamming up the machine.


Hello,
Here are a couple of things to try.

* Un-thread your machine and remove your bobbin. Clean any loose thread or lint out of your
bobbin case. Re-thread your machine, reinsert and re-thread your bobbin.

* Change your bobbin
There could be a nick along the edge of your bobbin spool that’s catching your thread as you
sew.

* When you start to sew a seam, grasp the upper and bobbin thread tails. Hold them back
and out of the way as you sew your first couple of stitches. This will keep them from getting
caught in your machine.

I hope this helps.

Needle jams and breaks off


Needle jams....Thread is caught in the hook...solution...Remove the upper thread and bobbin case,turn the handwheel backwards and forwards by hand and remove the thread remands.

Needles breaks
1. Needles is damaged..Insert new needle
2. The needle is not correctly inserted....insert flat side towards the back
3. Wrong needle size for the fabric...Choose a needle to suit the thread and fabric.

A horrible tangle


This is a bit late, could the bobbin case not be seated properly? You need to put it into place and then turn it clockwise until it seats soundly in the opening. Also, check for burrs...the needle may have left a rough mark on the plastic or metal in the bobbin area. A piece of batting, or even an old knee hi should snag on any rough areas.
