White Jeans Machine

So the top thread is not picking up the bobbin thread? Try a brand new needle. If that doesn't work, then the machine is probably knocked out of time. Search for sewing machine timing or take it for service.

hi Desiree.
this is all i could find out.
There could be several things that could cause the machine not to pick up the bobbin thread.

• The upper thread could be tangled.
  Remove the thread completely from the machine.
  The correct size spool cap should be used for the size of the thread spool.
  Re-thread the machine according to the directions in the manual.

One Point Advice Place a spool of thread on a spool pin.
One Point Advice Upper threading

• Remove the bobbin and make sure the bobbin is threaded properly in the shuttle race.
  Remove any loose threads or lint in the shuttle race.

One Point Advice Installing a bobbin into a bobbin case

• You could be holding the needle thread too tight.
  Hold the thread lightly to keep the end from going down into the shuttle.
• The needle could be thread incorrectly.
  Thread the needle eye from the front to the back.
• The needle could be bent or improperly inserted.
  Install a new needle with the flat side of the needle facing the back.

try increasing the needle thread tension and checking that the thread is actually between the tension plates

First thing to try is a brand new needle. A bent/damaged needle may not be able to pick up the bobbin thread.

Otherwise, it is possible it has a timing issue, ie the needle is arriving at the bobbin at the wrong time in order to connect with the bobbin thread. Search the internet web sites and videos. There is a lot of information on how to fix sewing machine timing. Or take it for service.

check to make sure that the needle was put into the needle holder correctly
all the way up into the needle holder--flat side of the needle to the back side of the machine
if the machine still doesn't up the bobbin thread then
it's possible that when the needle broke that it caused the machine to go out of time which means it has to be retime at a sewing machine shop

first let's deal with the needle becoming unthreaded, Keeping the needle threaded is easy, always keep thread tails of 3 to 6 inches on the top thread & bobbin at all times, & make sure the thread tail are pulled behind the needle before you start to sew,, this will ensure that the thread will not come out of the needle when you start to sew.

you mention the fabric is thin,, do you have a needle that's right for the fabric your sewing?
thin fabric needs a different needle than blue jeans fabric, check your top tension & see what the setting is on, usually 3 to 5 is good.

when the needle & thread are right for the fabric then the sewing is good.

also clean under the needle plate & bobbin area for loose threads or lint

also it's a possibility that the machine could be out of time & would need to be serviced by a sewing machine repair shop-as they have the tools for the job

Hello

The most common reason I see for bobbin thread not being picked up is that the needle is in backwards. Or the needle is a little bent (sometimes it's so little you can't see it, but the machine knows!). So start by trying a new needle (size 80/12 is what's used for test sewing on most machines). If that doesn't work, turn the needle 180 degrees and try again -- there is a definite front and back to a sewing machine needle.

Make certain that your bobbins are the exact ones recommended for your machine. Many look similiar, but if they are off even slightly in depth, they will not work. Also, make certain your bobbin in locked into position in it's case and the thread is coming from the bobbin in the correct direction. When holding my metal bobbin in my hand, the thread pulls counter clockwise before placing it into my front loading bobbin case. Each machine is different so check your manual.

check your needle to see if it's bent---roll on flat surface to see if it roll correctly
on some sewing machines when the thread comes off the thread take up lever it can cause the machine to jam
also if the bobbin thread becomes tangled it can jam
check the bobbin area for lint or loose threads
try having a top thread tail & bobbin thread tail of 3-4 inches
try holding the top thread tail & turn the handwheel on the right side on the machine manually & put the needle down into the bobbin area & see if the bobbin thread will pick up that way

make sure your needle's flat bit shows to the back and it is in deep anough. else your timing is out.
