Hello, I can't get the bobbin thread to come up. The needle isn't sending thread around the bobbin to bring it up. It is a White Sewing machine 1455. Thanks! Caryn

1. REPLACE NEEDLE W/FLAT PART AWAY FROM YOU.
2. MAKE SURE THE TOP THREAD IS PROPERLY THREADED.
3. INSURE BOTTOM BOBBIN IS ROTATING RIGHT DIRECTION. (USUALLY COUNTERCLOCKWISE) ALLOW THREE INCHES OF THREAD PULLED AWAY.
4. HOLD TOP THREAD W/LEFT HAND AND ROTATE HAND WHEEL TOWARDS YOURSELF. DOES IT BRING THE BOBBIN THREAD UP?
5. IF THE BOBBIN CARRIER IS INSTALLED PROPERLY THE HOOK (POINTED OBJECT) UNDER THE BOBBIN SHOULD "HOOK" THE TOP THREAD AND BRING THE THREAD AROUND THE BOBBIN THREAD. THE NEEDLE AND TOP THREAD SHOULD BE PULLING THE BOBBIN THREAD UPWARDS. IF THE HOOK DIDN'T "HOOK" THE NEEDLE THREAD THE PROBLEM IS THE DISTANCE OF THE NEEDLE AND HOOK APART OR THE TIMING. YOU MAY TRY TO MOVE THE NEEDLE TO THE LEFT SIDE AND AGAIN TRY ROTATING THE HAND WHEEL. IF IT DOESN'T WORK THEN TRY TO MOVE THE NEEDLE ALL THE WAY TO THE RIGHT AND ROTATE THE HAND WHEEL. IF IT BRINGS THE BOBBIN THREAD UPWARDS IN EITHER CASE IT WILL SHOW A PROBLEM WITH TIMING. THIS WILL NEED TO BE ADJUSTED BY A PROFESSIONAL.
6. REMEMBER TO PUT ONE DROP OF OIL ON THE RACE TRACK BEFORE YOU PUT THE BOBBIN CARRIER IN.

If a sewing machine fails to pick up the bobbin thread, it's usually because the needle isn't fully in the needle bar... OR its the wrong size needle for the machine.

Your machine probably needs to be adjusted and timed. But make sure you clean under the bobbin area before you try again... or take it to a machine pro

The bobbin is held in a removable bobbin case. If the bobbin case is already out of the machine, place the bobbin in the bobbin case such that the thread will come off clockwise. Leave a couple of inches of thread loose. Then pull the end of the thread down into the cross slot and thread it through the tension spring and into the delivery eye.

Next make sure the presser foot is up and the needle is in the highest position. Push the slide plate up. Hold the latch in the center of the bobbin case and place it over the center stud with the finger opposite the notch in the shuttle race. Release the latch in the center and press down on the bobbin case until you hear a click when the latch catches the groove. Leave a 2-3" length of thread extending out of the bobbin case and push the slide plate down. (Reverse the steps to remove the bobbin case.)

To thread the needle, place a spool on the spool pin with the needle bar fully up. I try to place the spool on the pin so that the little catch is out of the way. (The catch holds the end of the thread when the spool isn't in use.) Bring the thread through the guide loop on the top of the machine and then down through the thread guide on the right side of the tension discs. Bring the thread back up on the left side of the tension discs through the check spring and through the thread guide. Bring the thread through the hole (eye) in the take up lever (from right to left). Then bring the thread down through all of the guides down the face of the machine to the needle. Finally thread the needle from left to right. Pull a few inches of thread through the needle. (I find the threading of the needle to be easiest if the thread has been cut at an angle after threading the machine.)

The manual for the White 765 is available from Singer's support site. The direct link to the manual is http://www.singerco.com/uploads/download/827_white-765-x.pdf . See page 6 of the manual and the subsequent pages for pictures.

I hope this helps.

Hello,

You can take the slide plate off, that your needle goes through and watch to see if the arm grabs the bobbin thread, if you can get it to pick up, than slide scissors or something flat under your needle and manually pull both threads through, replace the plate.

Your bobbin thread could be wound to tight or spliced threads on it, and your tension needs to be adjusted. If your using a pedal, try setting to a slower speed.

I would try a different bobbin and thread it manually as in the step I mentioned, if you can't see the arm grabbing it, you will need to check to see if you have loose threading jammed in youir machine, if this isn't the case and adjusting the tension dosen't help...than you will need to replace the bobbin casing.

Kind regards!

Hello. What you have described presents a large number of possibilities. What I can tell you is this; A sewing machine that uses a bobbin is known as a lock stitch sewing machine. On a basic lock stitch machine, two threads are used to make the stitch - the needle thread and the bobbin thread. In order for the stitch to be made, the bobbin and it's thread are passed through a loop in the needle thread, or more accurately, the needle thread must pass a loop around the bobbin and it's thread, after which the loop is pulled back in and up, taking the bobbin thread with it right up to the underside of the fabric and securely holding it there and the process is repeated, many times over in the blink of an eye. The bobbin, weather placed in a case first or or set directly into, has a place in the center of a rotating hook, which can be oriented in either a vertical or horizontal position. It is the sharp, pointy hook that grabs the needle thread above the eye of the needle and loops the needle thread around the bobbin and it's thread. In less than one full rotation of the hook the needle thread is picked up, looped around the bobbin, and pulled back off of the hook, taking with it the bobbin thread and pulling it up tight to the bottom of the fabric. The process is then repeated, many times over in the blink of an eye. For a sewing machine to function correctly, every aspect of the process must be right, and if any part of the process is not spot-on, failure occurs. Process failure ranges in severity from one stitch out of a thousand skipped to catastrophic breakage of the machine and it's parts. I'm sorry I don't know of a White repair shop in your area. I am new to FixYa, so I'm not sure if it is appropriate to offer my services, but I think it is okay to give you my number if you want to call me. It is 574-808-9613.

You have described your problem just fine. Have you just changed the needle in your machine? If so, check it is in the right way, you want the flat shank to the back.

The needle has a scarf (scoop out) at the back - if it is facing to the front then the rotary hook (bit that goes around the bobbin and catches the top thread) can't catch the needle thread behind the needle.

Also check needle is fully up into the housing, this could also cause problem.

I'd suggest that you visit www.sewingabout.com and check out the pages on general sewing machine use, care and threading up, lots of helpful pictures and information which may be of assistance to you.

If it isn't your needle backwards (very easy to get wrong, happens all the time), then the timing could be out, which isn't so easy, but as its new I'd be very suprised if this was the fault. Just check needle, make sure top and bottom threads are threaded correctly and have another go. Also, remember to turn flywheel towards you.

Check the model number of the machine. White sewing machine manuals are available from Singer at http://www.singerco.com/accessories/instruction-manuals . Enter the model number and click Search.

Unlike some machines this one doesn't really need the bobbin threaded. Place the bobbin in the bobbin holder and leave about 5" of thread extended out from the bobbin holder. With the bobbin compartment still open, lower the presser foot and turn the handwheel to move the threaded needle through the stitch cycle. (I find holding the threads helps; normally, you'll feel them pulling under your fingers.) When the needle has returned to the top of the path, lift the presser foot. Then pull both threads around to the front (the bobbin thread should wrap around the top thread). Then move the threads to the back of the presser foot.

If the needle isn't catching the bobbin thread, first try a new needle (bent or dull needles don't always function properly). Next check the bobbin holder for nicks or other damage. There is a small hook on the bobbin holder that should be where the top and bottom threads intertwine. Under rare circumstances, you will find that the bobbin tension of the bobbin holder is misadjusted. This can interfere with the bobbin thread twisting properly. There is a little set screw that allows you can tighten or loosen the bobbin tension as needed. Adjusting the screw is to be avoided when possible and done in small increments (1/8 turn) if needed. It's easy to strip the threads for the set screw and end up needing to replace the bobbin holder.

I hope this helps.

Hello

Primary causes of upper thread breakage:


-- misthreading: pull all the thread off and thread again, using the manual, step by step. Read each step aloud before you do it. (sounds dumb, but helps.) (And make sure you thread the takeup lever!)

-- thread has wrapped itself around a thread guide or spool pin from one of the breaks. Take the spool off the machine before rethreading.

-- bad or damaged needle. Replace with the right size for the fabric, turned correctly (backwards needles skip stitches)

-- dirty machine, especially in the bobbin case area: review cleaning instructions and do it, using brush and vacuum only

-- bad/cheap thread: should not be slubby or break easy. Try another spool.

-- top thread tension too tight. 4 is normal for most fabrics, most stitches.

Tips;

1) do a light cleaning (brush and vacuum) every day you sit down to sew.

2) replace the needle if you hear it hit metal, if you've got a really bad thread jam, if you see it deflect as you sew (for instance, sewing over the side seam on jeans when hemming). Replace every 3-8 hours of actual stitching time anyhow.

3) buy good quality thread

4) when your machine isn't sewing right, stop; take all the thread off of/out of the machine (bobbin out of bobbin case, spool off spool pin) and give it a quick cleaning. Rethread from scratch, carefully. If that doesn't fix it, do it again, then replace needle and rethread one more time, manual in hand (yah, even if you've threaded it 8 million times before). #4 is curative about 98% of the time. The other 2% often requires professional attention.

The machine is relatively simple to thread. This is what I do and I've had no threading problems. 1. Put thread spool on the spool pin and put spool guard over spool pin to hold spool onto pin. 2. Take thread and put it under the bent tab by the circle tensioner. bring the thread around the right side of the circle tensioner and bring around the front of the circle tensioner thing back to the top hook on the far left side of the machine. 3. Take the thread around the backside of the top hook think until it threads through the flat piece on the left side of it. 4. Bring the thread down through the first (right side) channel and under the plastic piece to the second (left side) channel. 5. Bring the thread up the second channel and around the moving thread holder and past it's flat metal piece to hold it. 6. Tuck the thread around the small wire thread holder below the needle screw. This may take a few passes to catch it. 7. Thread the needle from the front and run the thread between the teeth of the presser foot. 8. Put a bobbin in the bobbin case so that the thread pulls off the bobbin from the left side of the bobbin if you look at it from above. 9. There is a small channel in the bobbin case that is covered by the bobbin tension flat piece. Pull the bobbin thread through this channel and into the empty space where the needle thread will catch. 10. Place the bobbin case into the machine with the little set bobbin arm pointed to the sky so that it fits into the machine without wiggling to the right or the left. 11. Turn the, uhhh brain fart, the hand wheel until the needle comes back up with the bobbin thread hooked over the needle thread. Take a narrow thing, like scissors or a seam ripper and pull both threads until the bobbin thread comes up. Now your machine is threaded. Use these directions with the pictures in the book to get this machine threaded.
