Machine not sewing

Even though I think I have threaded machine correctly it does not sew fabric together. Just cuts fabric off but does not sew it! Help needed pls! I think I've threaded by overlocker right (Riccar RL 913) but the stitching aint right, threads not weaving together, Needle is stitching on top but no back stitches while the lower & upper loops just trail along. What I am doing wrong?

    My huskylock 905 is jamming, I sent it for repairs and it sewed great for about 10 minutes then just jammed again. The repairer has offered to refund my money but that doesn't solve my problem. He thinks it may have something to do with needing oil inside somewhere. Any suggestions about where I should oil it as the only dealer is some distance away and it can take 3-4 weeks to get the machine back due to his heavy workload

    The overlocker is looping but not stitching on stretch fabric.

  • Anonymous Mar 29, 2014

    The overlocker is looping. However when I start stitching, does not catch on the fabric. only threads appear. When fabric is taken out, chain s are still there.

Make sure you have threaded the machine from right to left, it sounds like the needle thread is trapped under the lower looper thread and cannot form a stitch.........start the threading over from scratch like this:

  1. Lower Looper
  2. Upper Looper
  3. Left Needle
  4. Right Needle
Is there a diagram for how to thread on the inside of the door ?

Follow that slowly and carefully to make sure you have not missed any thread guides on the way, as each one needs to be followed through to ensure correct tension and thread progression.

If you are certain that all threaded correctly, did you have a fabric jam and pulled it loose ? If so, the timing may well be affected.

Post an update and we'll get this right.

    I have re-threaded my machine and that didn't help. I haven't gotten the surger to start sewing due to the error message that the upper knike needs tobe lowered (which it is). I am trying to do a cover stitch, I have it threaded properly and I lowered the knife. It is also in the "R" rolled hem position, as my guide instructs, but still, I close all the covers and it beeps that the upper knife needs to be lowered! Frustrating!

Upper thread always cuts. Straight stitch doesn't work. The upper thread always cuts. The tension is No. 3. The stitches is adjusted to no, 2. The fabric is thin, soft and Lacey . Please advice.

Be sure to install a brand new needle of the type suitable for the fabric you are sewing.
All About Needles

Use a thread that is suitable for the fabric. If you are sewing fine, light-weight fabric, use a fine thread--avoid old or bargain bin thread. Use the same upper thread in the bobbin.

When threading, always raise the presser foot so the thread will seat properly in the thread tension and verify that the thread path is correct (consult the manual).

Standard tension is usually the midway point between high & low number. The stitch length could be set a little higher than a 2--maybe a 2.25 or 2.5 for light fabric.

Since you are sewing fine fabric, it sometimes helps to use a removable stabilizer to give the fabric some extra body while stitching--perhaps a wash-away stabilizer if the fabric is washable.

Test your machine on scraps of the fabric you will be sewing. Re-adjust the tension as needed. The correct tension is when both upper and bobbin threads meet in the middle of the fabric.

If the thread continues to break, then there could be a burr or nick somewhere that is catching the thread and causing it to break. Could also be a needle/hook timing issue.

Help with Euro Pro 9000, the thread keeps getting tangled up in the bobbin area..

When I had this problem, even though I have been sewing for years, I was just not threading the needle properly. Make sure the presser foot is raised when you thread the needle. Another reason is that the thread is too old, the needle is not the correct size or type for the material, neither is the thread. Hope this helps. It's usually nothing to do with the bobbin, but the upper thread.

Juki hl sewing machine thread not sewing

Is there power to the machine? Will the needle move? Did you switch the bobbin winder off? (Even if you think you have, try it again.) Is the machine clean and properly threaded? Can you use the handwheel to raise the bobbin thread? Did you hold the bottom and top threads together behind the presser foot when starting the seam? Is the needle new and right way around and fully up in the needle clamp? Can you sew on paper, but not fabric? Did you drop the presser foot?
Some more information would really help. (So would a complete model number!)

My Brother LS2521i has had issues with the top thread snapping, and bobbin thread getting tangled. I've dusted, rethreaded, and done every trick in the book. This is a BRAND new machine! I haven't been...

Check for nicks on the thread you are using. Also try turning the thread around it may be catching on a little cut at the bottem of your thread. Also are you using the white circular piece which has a hole in the center looks like cotten batten ? That helps sometime to make the thread unravel correctly. Place that on then put your thread on.

Threads tangle, cuts material instead of overlocking.

tension must be set on five and make sure there is no cotton stuck in your tension unit

Janome 1600P-DB Tension Works For So Long...

It sounds as though the thread is jumping out of the tension assembly. The next time this happens, do not raise the presser foot before you do the following.Cut the thread above the needle and pull on it.If it is working properly there will be tension on it.If it is not working properly, the thread will pull through very easily.If the thread is coming out of the tension , either it isn't threaded correctly or you may need to wrap the thread around the bobbin winder guide to keep it from coming out.If you wrap it around the bobbin winder guide reduce the tension to around 2 , 3 or even less.
Hope this helps.

Machine not sewing

 If you have the machine threaded correctly, and are absolutely sure. New needles installed and it still does not sew, you most definitely have a timing problem. You should take to a qualified service center to be properly timed.
