Question about PfaFF Sewing Machines

1 Answer

Thread has wrapped around in behind the cb hook system and I can't figure out how to get if off to clear the thread. There is so much thread that I can't even move the needle up or down, it is jammed. Is there a step by step online guide to remove it? I did find one on line but it's not for the Grand quilter.

If you can open the machine cover you may be able to get access to the hook. That should allow you to remove the thread without having to remove the hook.

PE770 thread seems to be getting hung up on metal hook behind bobbin assembly


If thread is getting wrapped behind the bobbin assembly, most likely your machine needs service as thread behind the bobbin assembly should not be a normal occurrence.

The needle on my Pfaff 2044 won't move and the wheel won't turn. What do I do?


There may be thread caught in the bobbin area which is not allowing the hand wheel to turn. Remove the bobbin case and check the hook for threads wrapped around the spindle and/or caught in the hook mechanism. A little clear sewing machine oil in a pipe cleaner is sometimes helpful in freeing threads in this area.

Bernina 1008 thread bunching on bottom


"Nesting or Rat's Nesting" on the bottom side of Bernina sewing machines (CB hook type) is generally the result of very loose top tension. If the problem is found in newer sewing machines such as machines made after 1986 (serial numbers beginning with 26xx xxxx), may have an older Bernina bobbin case in the machine. The problem with the older bobbin cases is that the rounded projection of the latch on the left side of the casing will catch thread, preventing easy thread escapement during the take-up lever cycling resulting in loops on the bottom side and or thread breakage, etc..
Note:....Timings and modified latch geometry's were applied to later models to allow for good thread escapement. Older Bernina cases cannot be used on newer machines but newer cases can be used on all CB hook Bernina machines.
Additionally, Chinese copies of the Bernina/Cerliani OEM bobbin are rampant and can cause sewing issues. Always ask for OEM Bernina cases.

Note the following trouble shooting logic:
1. The center tension disk that is visible through the thread slot in the top cover of most machines must be positioned exactly in the middle of the top cover slot. By loosening the fixing screws on the top tension mechanism, one can adjust the disk position to center.
2. It would be a very rare situation for the top tension to change whatsoever from the (red center marking) factory setting. The most likely cause of loose top tension under the normal center mark position, would be accumulated lint, thread, or a sticky substance between the disks. This would prevent the tension compression disks from applying an even tension on the sewing yarn (thread). Often this can be blown out with compressed air when the presser foot lever is lifted in the up position. In some cases, soft drinks and other sticky or corrosive liquids can find their way between the disks. In this case, the tension assembly must be removed, disassembled, and the disks cleaned and polished.
3. Check the facial surfaces of the bobbin case for corrosion, and sticky substances that prevents the thread from easily sliding over the bobbin case.
4. Check that the spindle of the hook body is not bent or warped, causing the bobbin case to wobble, thus creating an intermittent pressure on the hook race cover at the moment that the thread is trying to escape over the bobbin case finger. (Replace the hook body)
5. Inspect the undercut on the hook body spindle for thread wrappings and knots. This condition can cause the bobbin case to press hard against the hook race cover, hence hindered thread escapement .
6. Exceedingly tight bottom tension can cause some problems as well. ( If you don't know how to adjust Bernina bobbin cases to factory settings, please ask).
7. Hook timing, (loop lift) can be out enough to affect thread escapement. This is typical of newer machines made after 1986 since Bernina no longer made fixed timed machines like the earlier Swiss made models. The later made models have timing components that can slip under stressed machine mechanics.

Why does the shuttle hook grab the spool thread instead of the bobbin thread? It wraps the thread around the bobbin and binds the machine up.


The shuttle hook is suppose to hook the needle (spool) thread and loops it around the bobbin case to form the lock stitch. Is it possible that something was adjusted without proper clearances as to allow the thread looping around the bobbin case to do so without catching up where it should pass through freely?

How to stop bobin thread from knotting


When loading the bobbin there is most likely not enough tension on the thread letting it overlap incorrectly. Try wrapping thread around a tensioner when filling and that should help. That way the bobbin is rolled as tight as the tension on the upper thread when sewing.

Don't know how to thread Pixie by Singer sewing machine. I tried following the instructions but this has not gotten me very far seeing as I am not familiar with any of the terms used in the manual.


try this site, I copied the instructions, but could not get the picture. when you get to te site i put dpxie in and search, on page 11 is the picture of the threading,

from the thread spool bring thread to the left, under the plate and up through the ****, around the round flat disk, then down the front of the machine (looks like a split in the machine) thread goes in this and around the u-turn (picture of a line that looks like a u-turn) an back up the opening opposite the first one. bring thread through hole in the metal loop, bring thread back down to needle area. there may be one or two places to loop thread behind hooks to keep the thread straight then through the needle from the front to the back.
(in the needle area DO NOT WRAP the thread around the hooks, the thread should just rest behind them to keep the thread straight to the needle)


http://www.singerco.com/accessories/manuals.html



1. Set the Power Off/Speed Switch to the OFF position.
2. Raise the presser foot lifter.
3. Turn the handwheel counter-clockwise until the needle is in its highest position.
4. Set the thread spool on the spool pin.
5. Bring the thread under the thread guide slot at the top of the machine and then slip it into the tension disk (1). Pass the thread into the tension disk, making sure it slips into the disk securely.
6. Bring the thread down, go around the U-turn (2), then bring it back up.
7. Pass the thread through the eye of the take-up lever, from right to left (3).
8. Bring the thread back down and thread the guide which is just above and to the right of the needle(4).
9. Thread the needle from front to back (5).

W3300 hook and needle


I had many broken needles before I put my thread on a thread stand behind my machine. I found that the thread was winding around the thread post and causing a jam and thus, breaking my needles. This solution worked!

Thread a kenmore 158 13410????


Not sure if I am too late, but it's pretty basic. I have the same machine...

You have the thread on the spool with the thread on the left side (unrolling off the spool counterclockwise) and put it around the round thing on the front middle (looks like a snap sort of) and through the eye almost right in front of it (the loop) and hold the thread lightly then wrap the thread around the tensioner (the thing with the dial) to the left (counterclockwise) until the springs "pops" it into place. Then run the thread through the little hook thing (by entering from the left) then up to the eye (hole) that is in the little arms that raises and lowers (you might need to spin the wheel to get the arm in the right position) then you run the thread back through the hook thing (entering from the left) around the little half circle thing (by entering from the left) and finally in the hole in the needle...

hope it made sense, I tried to use laymen terms...

good luck!

there is also a single screw on the bottom of the machine as well as one behind the bobbin winder, the last 'hidden" one is on the back side of the machine behind what woudl be the reverse button.
