Question about Brother LS-2125 Mechanical Sewing Machine

1 Answer

Same problem as Coozie - bobbin thread not advancing; bunching;

I think I'm threading the bobbin correctly but the needle just won't catch it and advance. It bunches and stops the needle from even going down. I can't find any good diagram showing how the bobbin should be threaded to come up the feed dog. Help! I see "solutions" but can't seem to access them.

Top thread is bunching underneath


bunching underneath is an indication that the top tension is incorrect
switching projects and materials also that attention has to be given to tension adjustment both bottom and top
the catching sometimes indicates that a tension is too tight and is pulling the needle out of line

Shuttle action not working, doesnt catch the down thread, bunches up thread and breaks needle.


Hi. I did not have this exact problem with my Featherweight. My machine was not stitching properly (top stitch looked so-so, but lots of thread bunching on underneath side of fabric). I took it to repair shop and learned that I was threading the needle thread on the wrong side of the metal plate which is part of the take-up arm (I do not think that the threading instructions make this distinction). After the repairman pointed out the problem & threaded the machine, it made a proper stitch.
My suggestion for this issue: check the bobbin threading. My bobbin has to be inserted so that it turns counterclockwise in order to catch the down thread.

also make sure the thread has not come off the thread take up lever
if none of these suggestions help, then you should consider
taking the machine to have it service, to see if it's out of time

I have a brother ls-2125 sewing machine. the upper thread is not catching the bobbin thread properly. help please


  1. Tension
    • Your sewing machine tension controls the rate at which the thread is fed through either the upper section of your machine or through the bobbin case. If your upper or bobbin threads aren't threading properly, sometimes adjusting the tension will correct this problem.
    Timing
    • Your sewing machine works by passing the upper thread through the needle of the sewing machine at precisely the same time the bobbin brings its thread to its uppermost position. If either the needle or the bobbin thread reach these positions too soon or too late, the threads won't interact and create the knots that make the seam. You can throw off your timing by sewing too many layers of fabric or hitting a pin with your needle. See you sewing machine repair facility to correct any timing issues.
    Thread
    • Thread can get snagged or caught in the upper section of your machine or on lint pieces in the lower bobbin section. If your threads aren't catching properly, you may be able to fix it by unthreading and rethreading both your upper thread and bobbin threads.

Necchi 215A Sewing machine Could anyone help I have a Necchi 215A which will not catch teh bobbin thread, I have tried a new needle and checked the bobbin is loaded and fitted correctly. The needle passes...


Make sure the bobbin has a 3-5 inch thread tail
Then make sure the top thread has a 3-5 inch tail
Then hold the top thread tail with your fingers (away from the needle)
& use the hand wheel on the right hand side of the machine to slowly
Lower the needle in the bobbin area & see if the bobbin thread will pick
Up that way

Thread is bunching underneath fabric


Needle in correct? Be sure your bobbin is not in upside down and turning the wrong way. Possibly the hook that the bobbicase fits in/on has been hit by a needle and caused a burr that is catching the thread as it comes around. The burr would have to be polished off or hook replaced. The machine could be slightly out of time also.
