The little metal pin under the bobbin has popped out making threading impossible since in winds u nder the bobbin - what do I need to do thank you

The bobbin may be in backwards
the needle is not the correct one for the machine
the needle isn't correctly seated in the needle clamp
the machine is a little bit out of time.
Remember to hang on to the needle thread when you're trying to pick up the bobbin thread
Turn the handwheel in the direction that would advance the fabric from the front to the back of the machine
make sure the bobbin-winding spindle has been pushed back to the left for sewing
make sure your needle is inserted correctly as far as it will go with the flat side facing back
and that the upper tension disks of your machine are threaded correctly.
Make sure the presser foot is up when seating the thread through the upper tension.
Turn the hand wheel (TOWARDS YOU ONLY) never turn the hand wheel away from you and hold the needle thread lightly. .
pull the loop up and then pull both threads (top and bobbin) under the foot and toward the back of the machine.
Also could be a timing problem

you can download the manual off this link below

You can get Necchi instruction manual from Necchi website: http://www.sewusa.com/Sewing_Machine_Manuals/Necchi_Sewing_Machines.htm". Makesure the needle is in the machine correctly- all the way up into the needlebar, make sure that it is threaded correctly, etc. If this all checks out ok,take the bobbin case out of the machine. There are two ears on either side ofthe bobbin case- turn the left one to the left and the right one to the right.Remove the silver ring, and inspect the piece of metal that the ring came off of(looks like a circle with the top cut off). You have to locate the hook whichis the piece that looks like a half moon inside the big round metal piece.Locate the tip of it, turn the hand wheel toward you until the needle is in thelowest position, at this point the tip of the hook should be flush with top ofthe left side of the cut off circle. Checkwhether underneath thread is looping on the fabric. If so then you've mis-threadedthe top, probably haven't raised the presser foot when threading so you can getthe upper thread into the tension. You need to thread the upper part with thepresser foot up. (You can put it down to thread the needle.)

Not picking up thread can be several issues, like bobbin is miswound, bobbincase isn't snapped in properly, you're using the wrong type bobbin, machine isout of time, needle is bent or burred, machine is dirty and in need of dustbunny eviction and a little oil but most of the time the issue is once againmisthreading: sewing machine needles have a front and a back and they have tobe placed in the needle holder correctly. In that case your manual is needed, take all the thread offthe machine (yes, spool off the spool pin, bobbin out of the bobbin case), pullthe needle plate and clean your machine thoroughly, using brush and vacuum (notcompressed air) and oiling per the instruction manual. Put it all backtogether, putting in a 80/12 needle, correctly oriented. Hang on to theneedle thread when you fetch up the bobbin thread.

Each and every seam you start is going to be done this way:
1) Pull the tail of the top and bobbin thread behind the presser foot
2) Put the work under the needle and use the hand wheel to lower the needleinto the work
3) Drop the presser foot
4) Holding the thread tails behind the foot, take a couple of stitches.
5) Drop the thread tails and sew normally. Hope this will help you. Good Luck.

Hi. Find the end of the thread and pull it out, off of the bobbin a couple of inches. Hold the bobbin with the thread coming off of the top so that if you rotated the bobbin counter clockwise it would wind the thread onto the bobbin. Now take the bobbin case in your left hand with the stem in the center of the case facing toward you. Stick the bobbin into the bobbin case and, taking the end of the thread, pull it to your left while pushing back on it somewhat until the thread enters the slot in the bobbin case. Pull the thread so that it slips under the thread tension spring, pull a little more out, then reinsert the bobbin case until it is seated all the way in the hook. It will probably have a catch that snaps in place.

Singer has manuals for most of their sewing machines available at their site. For the 2623, the manual is only available as a bound copy for $15. Go to http://www.singerco.com/accessories/instruction-manuals and enter the model number then click Search.

I believe on this model, you fill the bobbin with it on the metal pin on the top right of the machine. With a metal presser foot in place, bring the thread up and around the guide that pin. Wrap the thread a few times around the bobbin. Set the lever to the bobbin winding position and begin winding. Stop and trim the excess thread from your initial wraps after it is fully caught. Then complete winding the bobbin.

(On other Singer machines, you fill the bobbin in place with the bobbin cover moved halfway open.)

I hope this helps.

Hi Silvia,
I am having the same problem and am unable to find an answer. Please let me know if you've figured it out!

on the bottom bobbin if you look you will see a small metal flap this is the bobbin tentioner simply make sure the thread is under this flap ,and the top needle will do the rest.adrian.

Does the bobbin have a metal "peak" on it? If so, drop it in the machine with the peak up. Slide the cover only about half way till the 2 arrows on the left match up. Thread the top as normal, put the machine in straight stitch. Thread the needle, then put thread under the foot and wrap thread around the post on the left. Leave foot up. Hold onto the end of the thread and start your machine. The bobbin should be winding now. After a few wraps you can let go of the thread and it should have broken off as you continue winding till the bobbin is full.

At the top of the machine by the spool holder should be a post that slides back and forth. Put the spool of thread on the Holder and the bobbin on the post attach the thread and slide it one way and push on the foot pedal and that should start the process. Make sure you have taken the bobbin out of the bottom and the thread out of the needle other wise you will have a tangled up mess of thread in the bobbin section. Hope this helps! or Call Grama

Then your top thread tension is far too loose in relation to the bobbin thread.

First, check that the bobbin thread (the lower thread) pulls out with a little bit of tension. If it's hard to pull out then you have loaded the bobbin incorrectly or have a faulty bobbin case. If the bobbin thread seems fine then check that you have correctly run the top thread and have set the tension correctly. As you haven't stated a make and model it's impossible to give you more detailed instructions though.
