Help, the cotton keeps snapping on my overlocking machine? Its a basic Toyota, not industrial.?

Question

I am positive that it is threaded correctly, but after stitching a length of approx 6 inches, the cotton snaps.

I have tried different threads, different tensions etc.

I know its a vague question but was just hoping someone may have experienced the same! Its driving me mad!

Answer 1

Try slackening the tension and use good quality cotton. if that doen't work a sewing machine mechanic may be in order.
Sewing machines are one of my most unfavorite things.

Answer 2

If its the cotton that is threaded through the needle that keeps breaking, try changing the needle. When I have experienced that it is usually a less than perfect needle. This usually works for me. Otherwise try the other suggestions, slacken the tension knobs. It may also be the thickness of fabric, some machines are not very good on bulky fabric, particularly on the area where the selvages have been joined.

Answer 3

It is the tension. When was the last time your machine was serviced?

Give it a good cleaning and never ever use Coats & Clark thread. That thread cost me a $125 repair bill a year ago. When I call the sewing center with my problem with tension (couldn't sew 10 inches without the thread breaking) they said are you using C&C thread, I said yes they said stop it. I now only use Mettler, it is available at sewing centers and online.

Good luck and happy sewing!

Answer 4

Dollars to donut holes, it's misthreaded. Take everything off, including the cones of thread, and rethread again, following the manual steps in order. The three things I find when this happens are:
1) thread tree not all the way up
2) wrap of thread around the cone, around an eyelet, or around the needle
3) internal thread crossings wrong because it was threaded out of proper order.

Answer 5

Its the tension

Answer 6

Buy better thread.

Answer 7

tension too tight
