Birdsnest and machine jams

I was sewing on some felted sweaters and suddenly my machine stopped working. It is making huge birdsnests around the bobbin mechanism and jamming to the point where I have to cut the whole piece free from the machine. I went through whole spool of thread trying to fix it, just to give you an idea of how much it's winding up underneath. I thought it was a dirty bobbin assembly, so I took the bobbin mechanism apart, cleaned it thouroughly inside and oiled it. Still happened. If I pull the top thread while it's sewing, it will work for a few stitches until it tangles again. It seems like the upper thread tensioner doesn't work anymore, but I can't be sure of that (just a guess). If anyone has any suggestions I'd appreciate it!!

I have a singer 457 (from 1964!!) that I inherited from my grandmother. It worked successfully many months, but then I developed a similar problem (birds nests, tangles in the bobbin assembly).

AFter messing with the tension, different spools of thread, and what not, I found that it was the BOBBIN that was the problem. Althought this bobbin is the same size and shape as others, there is something about it that knots up the inside of the machine EVERY time (as in within 15 stitches or less).

I tossed the thing and have been trouble free ever since.

I am now convinced that bobbins (particularily plastic ones) wear out.

    I am so glad I read this comment. The birdnests were driving me crazy and since we are in China I was very concerned about where I would get my Janome 6600P serviced is I couldn't find an easy at-home solution. The problem was INDEED the bobbin. Bobbins have specific heights and the one I popped into my machine was NOT the proper height. Once I determined that...NO NESTS and NO more tangles. Thank-you!

Ok, this is real simple. pull the thread from the bobbin up through the bottom of the machine near the needle. also, hold the thread that you threaded through the needle with the other strand on the left of the needle. hold them there for a few stitches... and wahla! no more birds nest.

Try turning the thread spool around sometimes that will make a huge difference.

I have a kenmore 385.19110600 sewing machine...my machine seems to be sewing correctly until I try to sew very fine lightweight fabric. I get a "birdsnest" on the bottom portion of fabric. Why?

Most likely it is the top thread not pulling back sufficiently by the take up arm. This is controlled by top thread tension. Try increasing tension.

Test the tension mechanism by making a slow steady pull of top thread with foot up, then foot down. Note differrence between no tension (foot up) to selected tension (foot down).

I have a singer 3321 talent. Where the bobbin sits is catching & clumping, creating a birdsnest on the back. I tried rethreading both the bobbin and the top, checked my needle, adjusted the tension.

If you haven't already, install a brand new needle. Then make sure to RAISE the presser foot before threading the upper thread.

Also check to make sure the needle, thread, and fabric are compatible.

If it continues, then it probably needs service.

Bobbin tread bunches and jams machine

If the bobbin is inserted with the thread spinning the wrong direction this will cause "birdnesting" - thread build up under needle plate, you need to cut thread to get the item off machine. flip the bobbin over into the case and try again. Also make sure you remove ALL thread caught up in "Birdsnest" when they happen.

Bobbin always jams, thread bunches up under fabric, auto winding causes a birdsnest of ruined, loose thread and most importantly it won't sew.

Your tension is not set right. The tension setting is usually around 4 and can chang e depending upon the fabric you are using. Hope this helps.

Intermittent sewing problems

You have two problems:
1) Sometime it sews fine, but other times it will sew like there is no tension on the thread and create a "birdsnest" in the bobbin compartment.
Cause : Threading the upper thread
- clean upper thread tensions discs
- do not forget "• raise the needle and presser foot" (see manual page 18)

2) Sometimes it just randomly changes ...

My futura machine keeps every few seconds and stops sewing, what the problem

this was my first problem - if youhave had a "birdsnest" you probably damaged the bobbin case - take it out and run your finger aroundthe outside edge . You will probabaly find a nick where the needle has crashed down on the bobbin case. If you can sand it smooth it may start pulling the thread around the bobbin again. Twice I have had to replace the bobbin case. It is cheap just google on the internet. Now I have a spare if anything happens. I also found if you stick to the embroidery threads and not try to use up old or cheap thread it will run more smoothly.

I have Model HF 2022 and I am trying to make a gathering stitch (a long sttich that I can pull one thread and make the material ruffle). I have tried to use the number 4 length to do this but the stitch...

It is not the stitch length, but rather the thread tension that you change to do this neat little trick. Lower your thread tension to about 1, just enough so it won't birdsnest, then try again. You also might want to try an inexpensive ruffler foot (starting at about 15 dollars) or a shirring foot (around $5). These would help making toddlers and pleats a quicker, easier, more uniform task. ;)

I have a singer sewing maching model 3 57817c. I am making slipcovers, and have made several cushions already with no trouble at all. Suddenly the machine seizes up, and I can only procede by manually...

Is this machine older and has it been serviced recently? What weight fabric are the slipcovers made from. Domestic sewing machines will struggle with really heavy upholstery fabric, the feed dogs struggle to get two layers through smoothly. You can try to hold the fabric firmly front and back and guide it through but often four or even 6 layers when crossing seams will just be too much. You can try using a "humpjumper", http://www.punchwithjudy.com.au/shop/the-hump-jumper.html a little plastic bit that you hold under the foot at the back while stiching into a thick seam, it does help.

Does it need a good clean out in the tension and bobbin area? If it hasn't been done for a while break out the manual and give it a good clean out firstly, particularly the rotary hook and then give it an oil as per manual.

The jamming up sounds like tension issues, if you are getting a birdsnest on the bottom then top tension is the problem - check thread is going through the tension discs, turn it back to 5, lower the pressure foot and pull the top thread from just above the needle - it should be firm to pull. Also, if you can access them, turn tension dial to zero and "floss" between disc with the selvage edge of a clean piece of cotton fabric to remove any dye buildup/lint from the discs. You can also dampen the fabric with a bit of denatured alcohol or similar to help clean them.

Also did you change needles after sewing Velcro, it is very hard on the needle and would take the edge off it straight away. I use blue jean needles for velcro, even if the fabric isn't denim, the blue coating helps the needle get through the velcro, also, just sew in the margin where the hooks aren't around the velcro and go real slowly, I use the needle up/down button to get around the corners carefully for this.

So, good clean, oil, new needle, then set tensions back to normal setting and test sew on some fabric scraps. If its still mishaving then its possible that the timing is slightly off, take off the thread, remove the needle plate, and turn the flywheel manually while watching/listening as the hook goes around, does it pass behind the needle when the needle is at the lowest point? Sometimes timing might just be slightly out - probably best for a technician to address though which isn't going to help you get the slipcovers finished.

Spool is bouncing on spool pin

Get a stand alone spool holder, sometimes the spool pins arent high enough to support the thread or you can try a thread sock
