SOURCE: Bobbin case turns in its place

You need to remove the needle plate and take out the bobbin case. Examine it for any rough spots, scratches or burrs. When you find them, you will need to remove them with an emery stick and then buff it with very fine steel wool. Reinstall the bobbin case and the needle plate. Put the bobbin in the machine so that it turns counter clockwise when you pull the thread. Rethread the top of the machine and change the needle. Hold the needle thread , turn the handwheel and see if the bobbin thread is picked up without snagging anyplace. If it's okay, sew away.

SOURCE: Bernina 180 Bobbin case spinning

Its called the bobbin stopper. Pop off your needle plate by pressing on the marked corner. In the back on the left you will see a small allen screw which must have come loose. Position the bobbin stopper in place and tighten that screw. If it already is tight, loosen it and reposition the bobbin stopper in the notch and tighten it back up.
Good luck.

SOURCE: bobbin case on my 524fb necchi has come apart

Almost all Necchi use a class 15 bobbin & bobbin case, a new case should cost around 7 to 10 dollars!

SOURCE: using a bernina gold latch bobbin case on the Bernina 435 machine

There isn't a Bernina 435. If you are referring to the 430 than the gold latch bobbin case will not work in that machine. If you are talking about the Bernina 450 the gold latch will work in that machine, with or without the embroidery module.

I have a Bernina 770QE. The bobbin (black) is stuck in the bobbin casing (chrome). How do I get it to release?


Take the bobbin assembly loose and turn your hand crank and move it until the hook is at the top. Pull assembly apart and clean the assembly with qtip and sewing machine oil. It will likely be dirty that is causing parts to stick. If the bobbin spring feels weak it may be a good idea to replace it.

Bernina Deco 330 embroidery machine bobbin case tension.


There are tests to perform for testing and adjusting bobbin tension. There really aren't any "specifications" other than adjusting it until the bobbin drop test is where it is normally recommended.

P.S.--be sure to ALWAYS raise the presser foot when threading the upper thread to insure the thread seats completely in the tension disk.

The bobbin case went ajar while sewing blue jean fabric. I cant figure out to put it back in. Your help is very much appreciated :


Hi Debbie,
This type bobbin case can be a pain to get back in. On photo #1, at the top left you see a silver piece (circled in red) with a rectangular hole in it (circled in green)...take a flat head screw driver and insert it into the slot then twist to the right so the little bar/flange (circled in blue) will twist to the left past the bobbin well wall (marked in neon green). Photo #2 Now the bar/flange (marked in blue) should be on top of the bobbin well wall (marked in neon green). Now set the bobbin case in the bobbin well (marked in pink). Photo #3 as you set the black bobbin case in, kind of angle the flat part that is marked by the orange X so that it will begin to underneath the bar/flange with large orange circle. It won't go in all the way but just start it and then set the rest of the case down in the well. Now twist the entire black case to the right and the flat black are marked with the orange (X) should slide underneath the bar/flange marked with orange circle. The flat piece marked with a purple (X) should be sitting in the area marked with an (X) in the bobbin well. Now take your screwdriver and stick it in the rectangular box and twist it back so the silver piece marked in blue with go back over the edge of the black bobbin case to help hold it in. Hope you can understand my instructions and good luck!

How can I reinsert bobbin race back into my elna su 68?


Hey I can help you with this, its a long detailed explanation though. Have you removed the bobbin holden, ie,undone two small screws and lifted out the silver bobbin case, leaving a black round thing? This black bit is the lower ring guard, you have probably undone this to remove a thread caught in the edge of the bobbin case or umderneath. Elna manuals never detailed cleaning here but it is simple enough and needs doing from time to time, i have seen big wads of felted threads and lint under guard rings when pulling apart machines. This video shows how to line up the lower guard ring, the outer casing and the bobbin case.

Elna Lotus SP bobbin case repair Removing cotton jam from Elna Sewing...

I always turn the flywheel until the opening of the lower casing is facing forward, then look at the black lower guard ring and turn it until the cut out bit is facing the front. Now look a the bobbin case, it has a couple of silver Beaks and these need to fit in between the stoppers on the outer case. You will know if lined up right as it just fits straight in, wiggle a bit left or right until its lined up. Those two silver screws have to marry up with the two holes in the lower guard ring.
Once aligned , tighten up the two screws until firm. There is a dark coloured screw too, leave it alone.

Hope,is helps, once youve done this a couple of times, its easy.

How do I remove a stuck bobbin casing from a Bernina sewing machine?


Is it a drop in bobbin machine? If so, take off the needle and the needle plate (=throat plate), and you should have clearance to pull it out. If it's a vertical bobbin machine, taking off the needle plate may buy you the extra clearance you need to get things out again. Sometimes a drop of sewing machine oil every where you see a potential "bind spot" can help. Just mop out the excess oil after you've retrieved the bits that fell in.

My brother Disney sewing and embroidery se- 270d makes load noise and stopes tangles thread and material


I was just telling someone else that I recently learned from the sewing goddesses that be (at my local Hancock's Fabric Store)--that--you have to use the right bobbin. I mean plastic if your machine came with plastic. Class 65/ 55 (I think those are the numbers) as to match the machine's design. Use metal if your machine came with metal.

the bobbin case is weighted "just so" in order to be sure to run smoothly with the particular bobbin type.

Of course, the top tension and bottom tensions must be checked as well.

You could have some stuff stuck in the bobbin encasing thingy (it has two black tapered lever arms that you can move about 15 degrees to the outside and the case encasement pops out).

I have a faithful 730 Bernina and currently the bobbin thread keeps breaking. Please advise what may be causing this. Thanking you.


Bobbin thread breaks
1. There is a right way & wrong way to insert the bobbin in the case --when you insert the bobbin in if it doesn't stitch correctly turn the bobbin over see if that helps or bobbin case is not inserted correctly
2. Lint has collected in the bobbin holder
3. The bobbin is damaged & doesn't turn smoothly
4. Lower thread tension is two tight

here's a free manual

I have a Bernina Artista 180 that has a spring hanging down inside the door of the bobbin case area . Where does that connect


Your Bernina 180 is a rotary hook model and there is a bobbin case retainer mechanism below the sticth plate that has a long spring on it - it sounds like this has become detatched at one end and may well be affecting the stitch quality. Take the stitch plate out and you will see a black rectangular metal bar in front of the rotary hook mechanism - there is a small silver part in the middle that fits in a slot in the rotary hook bobbin basket - the spring should fit on this and then extend the length of the black bar and pull onto a retainer at the other end so that there is fairly strong tension on the silver part. If not this spring, then it's probably something that's dropped-off from elsewhere and maybe, possibly the feed-dog cam retaining spring. Let me know what you find.

Can't reinsert bobbin holder


You may not have the bobbin case seated properly in the bobbin well. Make sure the flat edges go underneath the metal flanges that are there to hold it in. I'm attaching photos of a similar problem I answered earlier that might help you understand how it goes in.

Below are the directions I sent with the photos...I hope this helps you! Good luck!

"This type of case can be a pain. First in photo 1, on the silver flange marked in a red circle there is a rectangular hole marked with a green circle. using a flat head screwdriver, insert into the rectangle and turn to the right. This should move the flange tongue marked with a blue circle towards the back white wall of the bobbing well. In Photo 2 take the black bobbin case and place in the bobbin well area marked with the pink spiral. Tilt the case slightly to insert the flat tongue marked with an orange X on the black bobbin case under the flange marked with an orange X in the bobbin well. Now let the black bobbin case sit in the bobbin well marked with the pink spiral. Now in Photo 3, you want to turn the black bobbin case to the right so the flat tongue marked with the orange X will go underneath the flange marked with an orange X. The other flat area marked with a purple X on the black bobbin case should line up with the purple X in the bobbin well. Once the black bobbin case is seated in, repeat the steps from Photo 1 in reverse to get the silver flange back over the bobbin case to hold it in place. I hope you can understand my directions and I hope this helps! Good Luck!"
