Question about Singer Sewing Machines

1 Answer

The thread is bunching up under the needle and needle keeps hitting something metal down in the bobbin case which then stops the machine. I've rethreaded bobbin, adjusted tension, checked needle & thread path and problem continues. My fabric is 2 layers of fleece. Also, my foot lever has stopped working and will not hold the foot up.

Your problem stems from the faulty foot lever mechanism. It's coupled to the upper thread tension control which only provides tension when the presser foot is in the locked down position.

If the presser foot won't positively engage in the down position, there's no upper thread tension and the thread bunches up below. Everything else stems from there. If the needle has hit the bobbin case too frequently then the bobbin timing may also be slightly out and the needle itself will be damaged and won't pass straight through the fabric; it only takes a tiny deflection from the vertical as it passes through the workpiece for the needle to flex and hit the bobbin case.

In summary, your machine is in desperate need of repair and adjustment. You haven't stated which exact Singer model you have, but they are usually easy to get servicing manuals for or you can take the machine to a sewing machine servicing specialist. Most singer spare parts (even for 100 year old machines) are usually still available fairly cheaply from a variety of sources, just enter "Singer spares" into your search engine to find suppliers.

To prevent re-occurrence, clean the mechanism regularly and lubricate it as directed by the manufacturer using sewing machine oil. Depending on how often you use the machine, do (or have done) a more thorough service periodically to check the timing and also that all mechanism screws remain tightly fastened.

I hope that my reply has shed some light on your problem and enables you to decide what to do next. Please take a moment to rate my answer.

I just bought it and its sounds like metal getting hit by the needle, and the thread bunches up underneath fabric.


if it is brand new then have it fixed under warranty
if used then it appears that the needle/bobbin timing is out with the needle hitting the bobbin carrier ot the hook hitting the needle.
bunching up of thread under the material is a sign of upper tension to light
suggest that you have a service done to fix it.

Looking for bobbin case for singer 3270c I see lots that look like the one I have but none of the numbers they list match mine... Also the machine is bunching up the tread and my bobbin case is broke so...


check with these 2 websites for the part ,,

sewingpartsonline.com or sewvacdoctor.com

it's possible the bobbin case could be a problem, I have 2 sewing machine & if one of them had a broken bobbin case I would replace it

have you tried a new needle

also check the thread take up lever, if the thread comes off of it, that can jam up the machine as well, I've had that happen before

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

My Husqvarna diamond top thread keeps breaking while doing loop embroidery. It sews a couple of stitches and then you can hear when the thread breaks. Ive tried changing the needle and bobbin, and cleaning...


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.

My bobbin keeps bunching up. I've changed the tension to 2, taken the bobbin case out, used a different bobbin....I don't know what to do. My machine is a month old and I've used it, maybe 4...


Put the tension back up to about 5. Rethread the machine entirely, and make sure you have the pressure foot in the up position when you rethread. If your getting bunching on the bottom, it's probably your top thread that's bunching up. After you rethread, put a small piece of fabric under the pressure foot, lower the pressure foot, and turn the handwheel in the forward direction and watch the thread as it comes around the bobbin case. If it goes around smoothly, try it with the foot control. If it hangs up as it goes around the bobbin case, you might have a burr on the black plastic bobbin case. Take it out, check for any burrs, sand them down, and try again.

Re-curring loose bobbin case


According to the manual, this is a drop-in bobbin.

If the bobbin case came loose, the needle would probably hit it and brake.

Take the bobbin out.

Turn of the power and remove the needle plate (under the presser foot).

Raise the needle to it's highest position and lift out and reset the bobbin case into the shuttle. This should be in the maintenance section of the manual. The bobbin case should fit snug.

Make sure the thread is feeding from the bobbin, counter-clockwise and through the guides on the bobbin case.

For a rotary bobbin with a metal bobbin case.

Remove the bobbin case. Make sure the thread is feeding clock-wise and through the guide on the side of the bobbin case.

Raise the needle to it's highest position - this puts the hook at the lower left. Left the tab on the back of the bobbin case and slip the bobbin case back into the shuttle with the "arm" straight up. You may have to move the bobbin case a bit to the left or right for it to snap into place.

If the problem persits, take the machine back to the dealer - there should not be a charge for fixing this as it is brand new - keep your receipt and warranty information at hand.

Missed stitches noise when it happens


Firstly, turn machine off then turn back on. Change needle. Re-thread the top and bobbin threads. Make sure you have not set the machine for a sideways stitch but you have been using a single stitch foot (recipe for Disaster!). BEFORE trying to sew, wind the machine by hand through a stitch or two (take the thread out of the needle's eye first) and look closely to see if the needle is in fact hitting something. If it is, then the needle needs re-centering and you will have to take the machine for repair to get this done.
Make sure the top thread is going into the tension disks. The presser foot MUST be up while you are threading. Hold onto the thread just as it comes off the spool and when you get down to the needle give a tug to be sure the thread is seated in the tensions before threading the needle. When you insert the bobbin, be sure the thread "clicks" into the tension slot on the bobbin case. Check the Sewing Advisor to be sure you are set for the correct fabric and stitch for what you are sewing. Have you cleaned out the bobbin area? Remove the clear or smoke bobbin cover, either use the tool provided or just press down firmly and slide forwards the metal feed dog cover (feed dogs down first), lift out the light grey plastic bit that half covers the bobbin case, remove bobbin case. Use the brush and clean out all the fluff from the bobbin area. Then check the bobbin case and clean it too. You can use a piece of strong thread or UNWAXED dental floss to clean out between the tension springs (the bit where the bobbin thread 'clicks' into). Reassemble the bobbin pieces in reverse order, making sure that when you replace the metal feed dog cover you push it all the way to the back and it too will 'click' into place. Hope something in the above works for you.

Janome Sew Mini bobbin problem


Hi, Usually wrap-ups in the bobbin area are caused by the lack of tension on the top thread. The slack arm ( shinny lever that moves up and down while sewing) has to pull the loop around the bobbin case and it does so only if the tension on the top thread is sufficient to keep it from pulling more thread of the spool.
Try this: Thread the top of the machine all the way just short of the needle eye. When the presser foot is up the thread should pull through easily. Now drop the presser foot (this closes the tension discs) and pull the tread while adjusting the upper tension control.
If everything is working correctly you should feel the drag on the thread change if not something is keeping the discs from closing.
Most Janomes aren't too difficult to remove the nose cover, usually just one screw and you can get a look at the thread path. Look for thread wrapped around the mechanism.
Sorry, no easy answer but I hope this helps.

Needle won't move; something stuck/dislodged


Can you remove the bobbin? Sometimes when thread gets bunched up under the lower plate it will force the bobbin out of position. Try taking it out and cleaning any loose thread and lint from the area. Put a couple of drops of oil on the outside of the bobbin case and re-insert it. Make sure you lower the needle and pull the bobbin thread through to the top and back behind the needle before beginning to sew again.
Hope this works!
