Hello Sue

It sounds to me as if you have knocked the timing out on the machine , you will need to have your hook timing adjusted. Also check the height of your feed dogs (at the highest point the feed dogs should be 1.1mm above the plate), If the feed dogs were too low when you started out with your project it would of caused you material not too feed and binds up the machine and knock the timing out

After threading the machine, start to sew and the thread breaks it seems that it gets caught in step 4 in Threading The Machine in the manual.


Not knowing the make & model of the machine limits out ability to help. What is Step 4? When threading the top thread, ALWAYS RAISE the presser foot. Verify that the thread path is correct--mis-threading is a frequent cause of broken thread.

Thread breaks when trying to sew velcro (with sticky back substance) on rayon material. e


Use a larger diameter needle and sew at half the speed also, find Velcro without the sticky backing. that will ruin your machines lower thread paths (Bobbin case and hook areas) and cause more issues when you are done with the Velcro sewing.

The top thread breaks

1. the needle thread is not threaded properly

2. The needle thread tension is to tight

3. The needle is bent or blunt

4. The needle is incorrectly inserted

5. The needle thread & the bobbin thread are not set under the presser foot when starting to sew

6. the threads were not drawn to the rear after sewing

7. The thread is either to heavy or to fine for the needle

8. Try a different spool or cone of thread


Bobbin thread breaks


1. There is a right way & wrong way to insert the bobbin in the case --when you insert the bobbin in if it doesn't stitch correctly turn the bobbin over see if that helps or bobbin case is not inserted correctly


2. Lint has collected in the bobbin holder


3. The bobbin is damaged & doesn't turn smoothly


4. Lower thread tension is two tight

if the sewing machine has a top loading bobbin, you may have to have the sewing machine checked to see if there is something wrong with the bobbin case or the hook and hook race.
I suggest try a new needle--one for the fabric being sewed
also try another bobbin
rethread the sewing machine top and bobbin, using every thread guide.

Thread breaking, not even threaded in needle anymore, thread gets caught on spool sometimes


Upper thread breaks
1.the needle may be bent or damaged--try rolling the needle on a flat surface to see if it's bent or not
Or the needle could be in backwards
Correct needle insertion
Correct needle insertion is mandatory for proper use of sewing machine.
Raise the needle bar to the highest point, then loosen the clamp screw to remove the old needle, place the new needle in the clamp with the flat side to the back of the machine or if using a round needle--the groove in the needle should face away from the shaft.
Push the needle all the way up to the stop or as far as it will go, then tighten the needle clamp screw
2.upper tension may be to tight--try 3 to 5
3.thread may be hanging up in bobbin case--check area for loose threads or lint
???
Lower thread breaks
The most probable cause of lower thread breaking is improperly wound bobbin
1.always start with a empty bobbin
Never wind one color over the other
2.choose thread that is identical in color & type as the one to be used for upper threading
3.wind the bobbin evenly across & in layers
4.don't wind the bobbin so full that it would be tight & hard to insert into bobbin case
5.bent bobbin--replace
6.lint built up in the bobbin case--frequent cleanings will eliminate this problem, the more often you use the sewing machine the more often it needs to be cleaned
7.thread catching on the bobbin spring or latch on bobbin case, check to see that the bobbin is inserted completely & correctly, & that you are using the right kind of bobbin

for the top & bobbin thread keep thread tails of 3 to 6 inches long pulled behind the needle before you start sewing

yes,sometimes the thread will get caught on the spool, you might think about getting a extra holder that sets behind the machine to hold those spool's that the thread get caught on, that's what I did.

Not sure if you noticed but if you thread a machine with the pressure foot down it will not thread correctly. There are two little things that sorta looks like symbols for the tension on most machines. (learned this when my viking 600e kept breaking thread and I put it in shop) If you thread the machine with the pressure foot down it closes the symbol things and the thread will break as you described. If you have completed that correctly check the spool of thread. You may have a burr on the thread spool that is catching the thread that too has happened to me.

This sounds silly, but I have the same machine and it kept happening to me too. Here's what I was doing wrong: When I thread it between 6 (thread take-up lever) and 7 (lower thread guide), the thread was being left exposed on the face of the machine instead of falling into that little **** of a crevice. One I figured out to stick it in the **** of the crevice, all was well. Try that -- and good luck!

Top thread on machine keeps breaking , sews for a while, jumps a few stitches then breaks. Seems to make one long stitch every so often.Thanks


Refer to the manual for threading and thread the machine with the presser foot up.

Make sure the bobbin is inserted so the bobbin thread is feeding in the correct direction from the bobbin spool and through the proper guides.

Thread frays and breaks when sewing and embroidering.


Make sure that the machine is threaded correctly, that the needle is in properly, that the bobbin case and bobbin are both inserted correctly and that you are not using old thread.

Make sure that there is a new needle in the machine and loosen the top tension about a number

You need to carefully re-thread the machine.
