SOURCE: Thread is bunching underneath fabric

Needle in correct? Be sure your bobbin is not in upside down and turning the wrong way. Possibly the hook that the bobbicase fits in/on has been hit by a needle and caused a burr that is catching the thread as it comes around. The burr would have to be polished off or hook replaced. The machine could be slightly out of time also.

SOURCE: janome straight stitch loose

I don't know if this is the right answer for any of you, but thought I'd put my 2 cents worth in. Often this can be the bobbin in backwards. It needs to unwind a certain way depending on the machine. I've heard a phrase for this: Mind your p's and q's which means some wind off to the right like a q, others to the left like a p. Mine has to unwind one way then be slipped backwards into a little slot or it does that loose bottom thread looping and bunching someone here mentioned. It seems everytime I get that problem I rethread the top thread 100 times before it clicks again and I remember it could be the bobbin thread. Either your manual will tell you the correct way, or you could experiment and try one or the other. Once you figure out whether you're a p or a q, mark it on your machien somewhere to remind yourself.

Good Luck and Happy Sewing!

SOURCE: Tension Problem on Pfaff 2034, bobbin loops

Rule of thumb.. Loops on the bottom, problem on the top. Loops on the top, problems on the bottom.

Set your upper tension at 4, and rethread the machine from the top. Just before you thread the needle, but the presser foot down. If the thread pulls right thru easily, then the thread is not thru the tension wheel right. Because, if you can't pull the thread thru with the presser foot down, you have it threaded right.

SOURCE: my needle thread keeps bunching and llooping on

If you getting loops on the bottom of your material, you need to re-thread the top of your machine. I say this because it is very rare when you will have to adjust the bobbin tension. But if you must, looking straight down at the bobbin as a clock- at 6:00 is the bobbin tension adjustment- lefty lucy, righty tighty. Hope this helps.





Make sure the needle is inserted in the machine properly- a good rule of thumb is the flat side of the needle should go to the opposite side of the last thread guide. Also make sure the machine is threaded correct
There is no standard tension for any machine to be set at. They start at four when they are brand new, however, after years and years the springs become compressed. You could start at four and then play around with it from there. If you are getting loops underneath the material, you are threading the machine incorrectly.

Pfaff 3.5 was working fine,suddenly thread is bunching/getting caught under plate.Thread goes around the bobbin ok,when gets near to needle gets stuck on hook on right side.Any idea how to fix please?


Just guessing. You might try :
Installing a brand new needle
tightening the top tension a bit

If it continues to be a problem, most likely the machine is out of time and requires adjustment. Search for sewing machine timing or take it for service.

ChaMy pfaff 2144 will not stitch properly; pools masses of bobbin thread; Changed thread, tensions, needle etc still wont sew, please advise as I am so desperate to fix this problem


bunching of thread under material is a needle tension problem
tighten it up
proper tension is when it requires a small amount of effort to pull the thread through the needle eye

Thread keeps breaking


The top thread breaks

1. the needle thread is not threaded properly

2. The needle thread tension is to tight

3. The needle is bent or blunt

4. The needle is incorrectly inserted

5. The needle thread & the bobbin thread are not set under the presser foot when starting to sew

6. the threads were not drawn to the rear after sewing

7. The thread is either to heavy or to fine for the needle

8. Try a different spool or cone of thread

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

The thread on the bottom bunches up all down at the bottom than bunches up


Usually problems like this are caused by improper bobbin winding and installation, incorrect tension, the wrong needle for project, or simply not grasping the threads and gently pulling them backwards when you start a seam.

1. Make sure you are threading the machine correctly.
2. Check your tension.
3. Check the bobbin, make sure it's wound properly and that you don't have the bobbin in upside down.
4. Check for bits of fluff and thread in the bobbin race area.
5. Change your needle, they wear out, get bent, dull... etc. You should have several different types on hand at all times.
6. Grasp both the threads gently and pull slightly backwards when you begin a seam. this will assure that your bobbin thread doesn't get all bunched up under the fabric.
7. Always test tension, needles etc., on a scrap piece of fabric before you begin sewing your project.

Needle thread looping underneath, threads not interlocking at all


If the machine is now threaded, lift the presser foot.

Now, pull about 10" of thread through the needle.

The next time you thread the machine, lift the presser foot first.

When the presser foot is up, the tension control opens and allows the thread to "seat" into the control, then when the foot is down the control closes to the indicated setting.

When threading the machine with the foot is down, thread does not enter the tension control and when you start to sew, there is no tension on the thread.

No tension = loosey, goosey, loopy stitches underneath.

Because the lack of tension on the top thread, the bobbin thread cannot lock a proper stitch.

My bottom thread is loose and bunchy. When I checked my seam, it got progressively worse from start to finish. This is a new machine, and I'm baffled. Nothing has changed from project #1 to this project #2...


The case that holds the bobbin in the bottom has a small screw that needs to be tightened. Do so by a quarter turn at a time and test the sewing on a scrap of the same material you are working on until you get an even tightness between top and bottom threads.

Thread bunches under the material


There ARE still parts for your 7570 - amazing how rumors can get around!

Could be any number of things - from something as simple as a thread caught somewhere in the upper/lower tensions to the tension assembly to timing to any number of other things? You may have already tried some of these - hope this helps:

  1. Try "flossing" your upper tension - this is nothing more than running a heavyweight thread (such as upholstery or 12 weight thread) through the threading paths. Grasp the thread at the beginning of the threading path and the end coming through the needle and "FLOSS" (back and forth - just like you do your teeth). This will usually pull through anything that is gently stuck.
  2. Pretty much the same thing for the bobbin thread - if you're comfortable doing so, loosen the tension screw on the side of the bobbin case to make sure there aren't any little bits of thread fuzz stuck under the tension plate on the side of the bobbin case.
  3. Also remove the needle plate to allow you to better see the upper part of the bobbin system - if there are any bits of thread, etc. stuck in there, you may be able to see them and pull out with tweezers (turn machine off before you do this so the tweezers don't accidentally come into contact with anything).

If this doesn't work, you'll need to have a sewing machine tech look at it (I would recommend a Pfaff-trained tech as they're going to be the most familiar with your machine). The 2140/2144/2170 use most of the same parts - even the new CV still uses some of the same parts.

Good Luck,
Kim
