Question about Bernina Sewing Machines

1 Answer

Problem with thread allways breaking. think its something to do with the block that the needles are mounted in. the block is at an angle instead of inline with the the machine. which then puts the two needles at an angle instead of inline with the machine. i have never seen this needle mounting block at an angle, only set inline with the machine. i can see where it is fixed and can alter. but i need the tech info for setup and adjustment. Oh! the sewing machine is an overlocker so it has two needles.

    It was the person we bought it off who said the thread was always breaking. after I cleaned and serviced it, it had been fine for a while.

    But now the needle hit the pin guide in the needle plate and bent it. Which is fixed (the pin guide) the timing for needles and loopers is out now. I believe it was always out a bit?

    What I need is the service info to set it up.

    Thanks anyone?

Most sergers on the market have needles that decend on an angle. Only a few are not made that way. Don't try to straighten it, the rest of the machine is designed with that "slant" in mind. Breaking thread in a serger can be many different things. Here are a few simple checks:
1. Change the needles
2. Make sure the thread is pulled deep into each tension unit, sometimes the thread will "ride" on the outside of the discs instead of being deep between the discs.
3. Check the needle plate and the loopers for rough areas. Sometimes the needles strike these parts and cause "burrs" which can grab the thread and not let go of it properly and it breaks or shreds the thread.
4. Some needle plates have pin like guides pressed into them. The sewing needles decend between these plate guides, however sometimes when a serger jams they can be broken. Verify that they are still there. They are very important for proper stitch formation, If they're gone, a new needle plate is needed.

I hope this helps

Kenmore mini ultra The top thread breaks off from needle after a few stitches. The bobbin seems to Be catching the top thread. Thank you. ??


If the top thread sews a few inches and then breaks, something is catching the top thread and holding it until it breaks. Usually, this will happen when using the old style thread cones with the slit in the edge to keep the thread from raveling off the spool. To prevent the thread from hanging up, turn the thread spool over so the slit is at the top instead of the bottom. Sometimes top thread breaks will happen if the thread becomes looped around the thread spool pin.

Remove the thread, ALWAYS RAISE the presser foot and then rethread the upper thread. Verify that the thread path is correct and that the thread has not looped around a guide.

If the thread is fraying at the needle eye, the needle/thread are not compatible. Also, the tension may be too high.

Check that the upper tension disk is clean--no gunk buildup or thread pieces stuck.

If the thread is actually breaking when it penetrates the needle plate hole, there may be a burr or nick somewhere below that is catching the upper thread. You can wrap your finger with a piece of fine fabric, like an old pair of hosier, fine knit fabric, etc. and running your finger around in the bobbin area, under the needle plate. If you get snags, then you have a burr or nick. If it is small, you can sometimes smooth it with a fine emery board. If it is a large burr, you may need to purchase a replacement part.


Why Does My Top Thread Keep Breaking Sewing Machine

Sewing Machine Thread Keeps Breaking

I have a Elna excellence 7600. Why does thread keep breaking while chain stitching fabric?


Thread breaks
first check to see if there is an actual thread break, then check the threading-both needle and thread
Sometimes the machine will signal a thread break when there really isn't one, at least not technically. For example, a mis-threading can cause the thread break sensor to think there is a problem because it is not sensing the proper thread tension. This can also happen if a loop of thread forms suddenly resulting in slack in the thread.
a thread break signal are really a "thread out" indication most often triggered by an empty or low bobbin or the needle becoming unthreaded.
rethread the machine and correct any low thread conditions.
Actual Thread Breaks
Examine the thread break. Is it a clean snap or is it shredded?
Next, examine the thread path. Did the thread get caught on something
A common problem with embroidery thread is that due to its slippery nature, it can slide down the spool and get hung up underneath causing a sudden jerk on the thread. Rayons will probably just snap at this point but some poly threads may be strong enough to resist breaking and instead flex the needle resulting in a broken needle.
Metallic threads often cause more breaks and shredding because they tend to form loops and kinks as they come off the spool. This is exacerbated by small spools with narrow diameters and short thread paths from the spool to the first thread guide. A simple solution for this is to extend the thread path.
Thread Factors
Lets look a little closer at thread. Embroidery threads are more fragile than those used for garment construction or quilting. Start with quality thread and know how to care for it.
Embroidery threads can dry out when exposed to light, heat, drafts, and air conditioning. They can become "bruised" if dropped or handled roughly. As they age, they become more fragile. Due to dying and other processes, certain colors break more easily than others. Check this for yourself. Try breaking a white thread and then a black. Also notice that the black is slightly thicker than the white.
Rayon tends to break easier than poly. Metallics are more temperamental and finicky
Needle-Related Possibilities
On a single needle machine, if you are getting continuous thread breaks with multiple colors and you are sure you can eliminate the thread, then look at the needle.
Is it the right size? For 40 wt rayon or polyester thread, a 70/10 or 75/11 works well on most fabrics.
Embroidery needles have a slightly larger eye to reduce friction on the thread. High quality needles have a well-polished eye that won't snag, abrade, or shred the thread. The thread can pass through the eye of the needle 50 to 60 times before it is laid down on the fabric. Any rough spot on the needle or thread path can literally saw the thread in half
The broken needle is the least of your problem! If your machine doesn't stop the instant the needle breaks, it may severely damage your fabric. Needle breaks can cause scratches and rough spots on the throat plate and in the hook area that can shred thread. Until these problems are smoothed out, thread breaks will be your reality.
It is possible for the fabric and/or stabilizer to the source of thread problems. For example, heavy, stiff fabrics can easily strip some metallic threads
If the lower thread keeps breaking, open out the bobbin hatch and check that there is no lint buildup that is hindering the smooth flow of the thread. If there is any lint, remove the bobbin and clean the area thoroughly with a brush. Also check that the bobbin is wound correctly and that the tension of bobbin thread is even. Poor maintenance and incorrectly wound bobbins are the culprit more often..

The top thread breaks as soon as i start the machine . i think i am threading it wrong


rethread the machine
thread tension to tight--set to 3 or 4
the thread is too thick for the needle-try this

Cut 6-8 inch piece of thread of the spool you are going to use for your project
Take the needle you are going to use for the project
& insert the thread thru the eye of the needle
& lift one end of the thread to a 45 degree angle
& if the needle is the right size for the thread it will slide down the thread
But if the needle hangs on the thread you need one size larger needle for the thread

change needle & make sure it's inserted correctly

if none of these suggestions work then you should consider taking it to a repair shop to be checked

I have this sewing machine and it seems that my tension on the top is too tight because my stitches on top are really tight and then the thread breaks. It feels like something needs to be greased or...


try the tension on 3-5 & see if thats any better,,
you might also check the needle to see if it's damaged or has a burr
it could be a belt going bad
also make sure the top thread is not caught on anything like the spool holder pin or tension disk
check to make sure the thread pulls easily around the tension disk
try rethreading the top thread
sometime the needle & thread are not compatable--try this & see if it works for you

5.needle damaged
6.needle thread is not threaded properly

Needle breaks
wrong size needle for fabric
wrong foot is attached
needle clamp screw is loose

also check for lint & pieces of broke needle under the needle plate
also the bobbin case area -take the bobbin & case out & check for pieces of broke needle

here is a tip about needle & thread

While quilting with clear polyester thread, the upper bar keeps dropping the thread or the thread breaks. What is the secret?

the needle top thread tension is to tight
the needle is bent or blunt

you said the upper bar keeps dropping the thread--I think you are talking about the thread take up lever-an old sewing machine service tech I knew had a sewing machine that had that problem & he took a pair of pliers & closed the gap in the thread take up lever hole & the customer never had a problem with the thread coming off the thread take up lever again.

Im pretty sure i have my singer 5525 threaded right but i think the bobbin is wrong but when i try to sew the top looks fine but the bottom is a thread mess an the thread keeps breaking


angle the bottom might be a mess but it is the top thread that
you see balled up .Pull the top thread and make sure there is tension on it ,if not check the thread is between the discs and there is nothing else between them .if this is ok there is something stopping the top thread from being pulled back up
through the needle plate to form a good stitch,if you can turn by hand and watch where it is catching you might be able to solve it.
