SOURCE: my sewing machine keeps getting jammed when

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.

SOURCE: Singer 301a...sews on top of fabric

This is a tension adjustment problem. It's good to use two different colors of thread, like you did. From your description, the top thread (needle thread) tension needs to be tighter. As you tighten the tension of the top thread, you'll see that the top thread pulls the bobbin thread up into the fabric so it's no longer laying loose on the bottom of the fabric.

You'll need to have the pressure foot down when you tighten the tension. Tighten it a little, sew a practice seam, check to see what the stitch looks like. Tighten it a little more, sew, check, etc etc--until both top and bottom look the same--you shouldn't see much (if any) of the bobbin thread color on top of the fabric or the top thread color on the underside.

Let me know how this works for you, ok?

SOURCE: The bobbin case on my Singer Inspiration 4210

unscrew the black plate that holds in the bobbin case and move it over to the left just a little bit, but make sure there is still clearance between the lower right corner of the case and the plate. The case should be able to wiggle a little, but not so loose it can pop out..

When I finish to sew the end of string does not lacks it self and when you pull the bottom of the string everything opens


If the upper thread is looping on the bottom of the fabric as you sew, the upper tension is too loose. It could be threaded incorrectly, the upper thread may not be seated in the tension disk properly (be sure to RAISE the presser foot BEFORE threading the upper thread), or the upper thread tension is set too loose.

If you have checked everything and it is still looping underneath, the bobbin tension may be too loose or the bobbincase needs replacement.

When I am sewing it will sew about 3 stiches and then jam.. It does it if I change weight of material or it will s kip stiches.


Skipped stitches is usually indication that needle is blunt or burred.
Or if you are using a sharp needle on knit fabrics it may also skip a little.

Not sure what you mean by "change weight of material" - do you mean you are sewing applique and going from one fabric weight onto another? or different sewing projects?

It is a good idea to change your needle for each new project (4-6 hours sewing time max) and choose the right type of needle and size for your project.

However, the jamming part sounds more like thread tension issues, especially if the jamming is happening underneath from the bobbin. If stitching is loose underneath, then top tension is the problem and visa versa.

Recheck your threading path, top and bottom tensions and that you have good quality thread. Change the needle, rewind a fresh bobbin, thread up and try again.

There is really good info on www.sewing.about.com or I refer to my Singer Sewing Machine textbook at lot too. Good luck.

Jams up when attempting to sew, making loud noise. Thread mass under fabric when able to cut loose from machine.


Thread jams underneath usually are caused by top thread tension issues. Things to check:
top tension discs are clean and no thread traces caught in there, tension is set to medium number usually 4 or 5 and that the top thread is running freely from the thread spool, correctly thread through the tension discs, and down to the needle. Lower the pressure foot and pull the thread from just above the needle; it should feel firm resistance if under tension correctly.

As you've had a good jam up, good idea to now remove the bobbin, needle plate and bobbin holder (refer to your manual if you have never done this before) and clean out the hook area well, look for any fine thread remants and brush out any lint etc. Oil the rotary hook area as per your manual. Now reassemble, and rethread everything again checking that the bobbin thread is clicked into the tension spring and that the top thread is through the tension discs correctly.

Also, pop in a new needle, flat shank to the back, then try again.

Good luck with your machine.

The bobbin case sounds loose and the thread jams with the fabric and everything gets stuck.


That use to concern me too! I thought it signalled a problem, but my bobbin case has always been loose and that was not what was causing my thread and fabric jam. Usually what causes the jam is an incorrectly wound bobbin, wrong needle or old needle, old thread, or a slightly warped bobbin that is hard to see/detect. Change everything out--needle, thread, bobbin...this usually does the trick!

The bobbin thread is sewing loose stitches and jamming the machine. I have re-threaded everything, brushed out the bobbin casing, changed needles, adjusted thread and bobbin tension, and am stuck and...


Always have the presser foot up when you thead any sewing machine.

Make sure the flat side of the needle shaft is facing to the back of the machine.

Don't do anything to the bobbin tension. Set the top thread tension to what is recommended by the mfg.

Make sure the thread from the bobbin is feeding from the bobbin in the correct direction and through the correct guides.

After inserting the bobbin and threading the machine, lower the needle (hold on to the thread tail) and then raise it by turning the hand wheel by hand to pull up the bobbin thread.

Gently pull the two threads under the presser foot and to the back of the sewing machine before you begin to sew.

Bobbin thread getting jammed


kyoungblood4
Are you making sure that your pressure foot is up when you thread the upper thread? If it isn't then your thread is not seating correctly in the tension disks. It will then be loose and make a birds nest(mess) under what you are trying to sew. The other thing to check is which way you are putting the bobbin into the bobbin case, different machines do it different ways. Some want the thread to come out of the case in the same direction as the slot on the case and some want it to come off in the opposite direction.

Guest,
Probably when your son broke the needle he knocked it out of time. You will need to have a sewing machine technician to repair that.

Hope this has been helpful for you bothl Liz M

Thread getting caught underneath


you need to replace your shukle that holds the tread bobbing below.it is either slack or broken . if it is slack then you tighten the little screw that holds a cover that gives the thread tension .if its broken then replace it.once the thread is slack below it will cause your thread to bundle up.
