Everytime I go to sew the thread always knots up

Are you getting knots under the fabric when you sew? If so, that is bird nesting (thread nesting) and is commonly a top thread issue. Most often the thread is not seated fully in the tension disk or the top tension setting is off.

Remove the top thread from the machine.
ALWAYS RAISE the presser foot and rethread from the beginning.
Verify the thread path is correct.
Set the tension at the midway point and then tweak it so the top and bobbin threads meet in the middle of the fabric.

What causes Bird Nests Superior Threads

Are you saying the upper thread is knotting under the fabric as it stitches? This is bird nesting or thread nesting and is generally caused by mis-threading, the thread not being seated in the tension disk, or the upper tension too loose.

When threading the upper thread, ALWAYS RAISE the presser foot. Verify that the machine is threaded correctly. If one guide is missed, the stitching will go haywire. Start out with the upper tension set around the midway point and then tweak it through test stitching.

Please check your fabric results. Is it the bobbin thread that is accumulating under the fabric, or is it really the top thread that is globbing and knotting under the fabric. Usually, thread mishaps under the fabric are the result of an issue with the top thread.

ALWAYS RAISE the presser foot when threading the upper thread. This releases the tension disks so the thread will seat properly. Use a brand new needle. Start out with the upper thread tension set midway between high & low numbers, although this can be tweaked.

If it is in fact the upper thread, then here are some suggestions:

Troubleshooting Thread Nesting Sew Toot

The bobbin thread must go through the bobbin tension guide before it can be picked up to the bed of the machine by the needle thread. There must be a mistake in threading the upper thread or the bobbin thread, or both. There are lots of manuals for sewing machines online and plenty of sewers who can help you in the area where you live. It's not a big problem just go to the nearest sewing store in your area and you'll get lots of help.

It sounds like there is no tension on the bobbin. Can you give me the brand and model number of the machine? There are so many ways to insert / tension a bobbin that without that I can't be much help.

on a normal sewing machine this usually means the threads are all snagged up in a knot in the bobbin case. Snip your threads, wriggle the fabric out, remove all snagged threads and rethread the machine. I don't know if this will work with your blind hemmer.

Hello

The feed dogs should be in the highest position for regular sewing. If the feed dogs are not raised above the plate it will do this. With the machine unthreaded and no fabric.. run the machine to see if the feed dogs are moving and are working.

.Always make sure you have about 3 inches of both threads before taking any stitches, and both threads are positioned directly behind the needle.

make sure you re-thread it exactly as the owners manual shows.

hi there,
well, common problem when you didn't acquired right set up of tension and clean feed dog,bobbins,shuttle race.on figure right bobbins winding.set up counter clokwise thread rotation, set dial tension on #3 to #4, dial stich to # 8 to #12
only on cotton fabrics,others fabrics such as silk..etc,gradually adjust tension fine the smoothest adjustment,
on fig,thread looping top side threading follow threading so you can have fine sewing.also clean under bobbins from chips fabric and dust.have a nice day,don't forget to rate my fix,ythanks a lot

In 99% of all problems with "bird's nesting" or "knotting" it is an issue of the thread coming out of the take up lever (at threading guide #3) (from the spool; through the first thread guide at #1 down to #2 and up to # 3) when the thread comes out of the take up lever, the machine can not regulate the thread and it floods the machien with thread and wraps itself around the bobbin case. OR! Your tension is too loose. Raise it. Your machine should preform perfect at tension #4 unless you are using speciality threads or fabrics.

ALWAYS be in the habit of threading your machine with presser foot up so that while threading between paths 1 and 2 you are certain to have the thread pass throught the tension disks.

This will happen on a $50.00 machine or a $5,000 machine. The thread needs to be regulated.

USE GOOD THREAD!

Thanks,
