Question about Bernina Virtuosa 150

Upper thread will not catch bobbin thread

When sewing I get irregular seams due to the fact that the upper thread often doesn't 'catch' the bobbin thread. This leaves me with wholes in my seams, sometimes even 3 cm long. I have cleaned my sewing machine, changed needles, changed thread, but nothing seems to help. What can I do?

Your machine is out of time. It would be best to have a tech adjust the timing.

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.

There is something wrong with the bobbin. When I sew it catches somewhere and bunches thread up underneath


Does this only happen when you begin sewing????? Make sure your upper and lower threads are long enough for you to hold them.......lower your pressure foot and don't release the threads until you have sewn several stitches into the seam. If you don't hold the threads when starting a seam...both threads often get pulled down into the bobbin area and cause a big tangled mess. Hope this helps.

Keeps getting jammed


Hello,
Give these solutions a try.

* Un-thread your machine and remove your bobbin. Clean any loose thread or lint out of your
bobbin case. Re-thread your machine, reinsert and re-thread your bobbin.

* Change your bobbin as there could be a nick along the edge of your bobbin spool that’s catching your thread as you sew.

* When you start to sew a seam, Hold the upper and bobbin thread tails back and out of the way as you sew your first couple of stitches. This will keep them from getting jammed in your machine.

I hope this helps.

Lower thread keeps jamming even though bobbin case is clean and tension on thread has been adjusted.


Hello,
Here are some things to try.

* Re-thread your machine

* Change your bobbin
There could be a nick along the edge of your bobbin spool that’s catching your thread as you
sew.

Also, before you start to sew a seam, grasp the upper and bobbin thread tails. Hold them back

caught in your machine.
I hope one of these solutions help.
