The bobbin grinds when I start to so

The bobbin makes a grinding noise when I start to sew. Especilly when I am doing a fancy stitch like applique. Once the machine is running, it doesn't grind anymore but evetually the bobbin thread get bound up underneath. I took it into the shop for repair, they reseaded the bobbin case and said it was fine. It still does not work though.

Sounds like a bobbin case related problem. Unplug the machine, then remove the needle plate to get access to the black bobbin case. Inspect the underside of it  VERY carefully for ANY marks or roughness. You can expect very fine 'scratches', but no chunks or rough bits.Now check the metal rim that the bobbin case sits on is PERFECTLY smooth. particularly look for any tiny burrs on the top or inside edge of the rim, or any sign of a needle hit. Should not be any! If there are, the mechanic shoul fix it at no extra cost cos he missed the problem. Whilst checking the bobbin case, look for ANY marks on the top surface of it. The SLIGHTEST mark WILL upset the sewing.

Hope this assists!

Kenmore 16 stitch sewing machine. Will sew for a couple of stitches then grinds and stops. Clump of thread in bobbin . I cleaned out the hook race and bobbin. Any ideas?

It has happen to me with my machine, either you did not thread your machine right or the bobbin. You need to rethread your machine and make sure that the bobbin is threaded right too. It can be very frustrating!!


Make sure your presser foot is in the up position before you thread the machine. Dull, bent needles will cause stitching problems, can make the machine work harder, or can damage the machine or your fabric so change the needles often; some say after two medium size projects. Dull needles can make a plucking noise so listen to the noise your machine makes right after you put in a new needle. Make it a habit to listen to the needle noise as you sew also. Dull needles make a "plucking" noise. Check to make sure the top thread is engaged between the two tension disks and that there are no fuzzies in the tension disk or bobbin/ throat plate areas. Make sure the thread and needle are compatable. Refer to your sewing machine manual or find an online chart that references your thread to the proper needle type, size and the proper fabric types that work best. Use the same thread in both top and bobbin. Completely remove your thread and try another thread - top and bottom. 100% polyester thread is some times problematic. Some machines won't sew with certain threads. If nothing worked, you will probably need to adjust the top tension knob. There are some good youtube videos. Look for one with a higher number of views. Loops under the fabric means you need to tighten the top tension (turn knob to right) gradually until you get a proper stitch. Most experienced sewers do not like to adjust the bottom tension screw on the bobbin case if it can be avoided. Bad things can happen if the screw pops out :( !!! I have a friend who sewed all her own clothes in 4-H, high school, college, and many of her children's clothes. After about 40 years of sewing and properly maintaining her machine, I received a call from her because nothing she did worked to get her machine to sew a good stitch. She had no idea there is a bottom tension adjustment on the bobbin case. One last time...do not adjust the bobbin case tension unless you know what you are doing. The screw should never be unscrewed so that it pops out. It will often not go back in correctly. Some some sewing machine repairmen/women can rebuild the bobbin case if the screw is still good. A new authentic bobbin case from the manufacturer can be pricey. One of the most common problems are tension problems. Do not let children or inexperienced adults mess with your knobs. There are youtube vides that address just the bottom bobbin case tension adjustments. If you are working on an important project, write down the type of fabric and thread you are using, stitch length and width settings, and the number setting on your tension knob. Or you can take a picture of it on your phone. This is even more important for sergers. I also record this information for appliqu? stitches, top stitches and quilting stitches (etc.) and keep it with the pattern envelop so if I make the project again, I have a starting place and save time and frustration. I hope this helps you.

My Janome New Home is grinding

I don't know your experience with this machine so bear in mind.

Your "grinding" could be the machines internal slip clutch, but just guessing. Likely you can't make needle move up/down with handwheel or make a full or multiple turns of handweel ?

If yes, then check the bobbin area (hook and race) is not fouled with thread and/or fabric.

If bobbin area is clear, then try changing the stitch selector to see if its jammed as well.

What type of sewing were you doing when this occured?

Comment here and I'll assist further if need be.

How do I get needle foot out of zig zag mode.keeps jamming and making a grinding noise.?

Try turning the flywheel and changing the stitch selector at the same time. You may be in between stitch settings while trying to sew.

How to applique with my Quilters Dream sewing machine

You should practice on scrap fabric until you can get the technique down well. There are different kinds of applique.

To cover raw fabric edges, you can do a smooth line of zig-zag over the fabric edge. Set the stitch width to a wide stitch and shorten the stitch length until the thread lays nicely next to each other with no gaps of fabric showing but also not so close that the stitches are on top of each other. There are methods for turning corners or curves that are nice for making a great looking edge.

Some tutorials may be helpful.

Why does the machine hesitate and make grinding noise?

what kind of grinding noise does it make?

try changing the needle--use a needle that is for the fabric being sewed

look in your sewing machine manual and see if the machine needs to be oiled

also clean in the bobbin area for lint

also check to make sure that the bobbin is inserted correctly

I have a Bernina 145 S activa and I can't get my satin stitch to work , it brings the bobbin thread to the top , what can I do ?

Do you use stabilizer when you are satin stitching? I had a teacher who also hooped the fabric with a spring-loaded embroidery hoop (turned upside-down under the presser foot so the fabric is flat against the needle plate) that would keep the fabric taut.

It is not uncommon for bobbin thread to rise to the top when doing embroidery, satin stitch, etc., especially if you are using lighter-weight thread than usual. You would normally loosen the upper tension so the upper thread will sink into the fabric. However, if loosened upper tension is not doing enough, you may need to adjust bobbin tension when doing embroidery, applique... You might try tightening the bobbin tension just a smidgen to get the bobbin thread to stay below the fabric. Be sure to mark the bobbin case before making any adjustments so you can return it to the original setting when finished with the satin stitch. (If you do a lot of satin stitch or applique, etc., you may want to invest in a separate bobbin case that is set up only for doing that kind of work--saves having to alter the bobbin tension frequently.)

How can I use my Bernina 640 Artista to applique

Perhaps I'm not understanding your question. When doing applique, I use a very tight zigzag stitch with a satin stitch foot or open-toe embroidery foot (so the thickness of the stitches do not create buildup under the presser foot). Set the tension so the bobbin thread stays mostly under the fabric so the top thread is the only thread that shows on the top (sometimes threading the bobbin pigtail will help).

Fuse the cutout fabric to the backing fabric. Then zigzag so the raw edge of the fabric is covered by the zigzag (helps to use a thicker thread so the coverage is easier).

Some newer machines have the ability to miter corners. On my 930, I set the needle position to the outside of the raw edged. Then when I near the corner, I gently, but consistently, narrow the stitch width to an an outside point, since the needle on the outside edge, turn the fabric and gently, but consistently, widen the stitch to full width. This creates a nice mitered corner.

When making curves, stitch small lengths and then sink the needle on the outside of the curve, and gently turn the fabric to follow the curve and repeat while going around the curve.

Nv500 brother machine maked a grinding sound and wont stitch it just gathers and knots can you sugest what it might be?

Something is bound up. Stop trying to sew. Turn off the machine.
Take off the foot, take out the needle, take off the bobbin cover, take of the needle/throat plate and check for the reason for your problem. Look for lint, threads caught up underneath and in between the parts.

Clear all that out and put it back together and attempt test seam.

I have a brother SE-400 and it sounds like the bobbin case is grinding.

I have a Brothers SE400..while free motion quilting, it sounds like the bobbin case is bouncing around. A lot of clanking noises. Does anyone know what I need to do to adjust this problem? It also seems like my stitches are very small and tight. I do see the top thread overlapping with my bobbin thread on the backing...what do I need to do to adjust this problem
