Question about Necchi 3620 Quilter Mechanical Sewing Machine

1 Answer

Machine stopped sewing even though it sounds like its running

After I bent the needle and a basting pin, the machine flywheel would not turn even though it sounded like it was running. The sound was a high whining sound. Does the machine have a belt that's maybe slipped? Can I fix this myself?

I would suggest taking the machine to be checked to see if the machine has a broken part or jumped time.

SOURCE: bobbin/raceway and timing problem; Necchi 3577

ok.....without the bobbin case in and a fresh needle in, turn the machine to the side and turn the crank wheel counter clockwise, the hook of the machine should bypass the cusp of the needle, thats the part of needle that is by the eye and curves in alittle, if it is not the timing is off, try to adjust this by adjusting the needle bar, this is not a easy easy repair but takes patients, im assuming that, thats where it was thrown off timing

SOURCE: Need to find a compatable replacement belt for a discontinued sewing machine.

Sheila,
I called the company which sells Necchi Machines and parts(Allyn)
in the States about the belts.Their Number is 800-525-9987. The parts department says Necchi used several different motors with differing motor mounts which means there is no standard motor belt for this model machine. The only way to get the right belt is to either take in the machine or the old belt to your repairman. More than likely he will have a Generic belt which will work.

SOURCE: I just replaced the belts on my Necchi 535FA, but

If the belts are not tight enough they will slip, they should all be fairly tight but not like a piano string if you know what I mean.
As you do not describe what the machine is doing wrong I can not really say any more at present, except make sure there is no oil on the belts and the machine has no tight spots when you turn it over by hand.

I have a Bernina 180 sewing machine that the needle is not coming down?


This might be a bit hard to explain without showing you a video or photos, but here goes.
The 180 and many other Berninas do what is called a basting stitch. When a machine is doing this stitch the needle stops going up and down for a very short time this producing a long basting stitch. There is a mechanism on the needle shaft that has a black short lever on it. When the basting selanoid pushes in on this lever the needle stays in the up position. Simply stated this lever mechanism can stick if it is not oiled and your needle will stay in the up position and not move when the machine is running. Sometimes just pulling the needle shaft down, then letting it go so it snaps back up into place will lock the basting ever back in place. Once you get the needle shaft to lock back in everything will work again.
I can guarantee you that this is your problem if the machine runs but the needle stays in the upper position. I pose helpful Bernina videos on YouTube under the name JoeKind1958. It would be so much easier to show you how to oil the basting assembly on your machine. Contact me through that site and I can make a video showing you what to do.

I was sewing, turned the machine off to pin something, and when I turned it back on, it jammed in the bobbin area. It will only stitch one stitch and then jams. I have taken it apart over 30 times, and...


have you tried changing the needle-
1.the needle may be bent or damaged--try rolling the needle on a flat surface to see if it's bent or not
Correct needle insertion
Correct needle insertion is mandatory for proper use of sewing machine.
Raise the needle bar to the highest point, then loosen the clamp screw to remove the old needle, place the new needle in the clamp with the flat side to the back of the machine or if using a round needle--the groove in the needle should face away from the shaft.
Push the needle all the way up to the stop or as far as it will go, then tighten the needle clamp screw
2.upper tension may be to tight--try 3 to 5
3.thread may be hanging up in bobbin case--check area for loose threads or lint
???
check the thread take up lever-if the thread come off the thread take up lever that will jam the machine up--I've had it happen to me

I have the singer 7442 and i cannot figure out how to get the baste stitch for gathering material on a flower girls dress. I've tried everything and there's nothing in the manual, can you help with this?...


Normally to gather fabric, you select the regular straight stitch, turn the stitch length up to maximum (4 or 5 usually), and stitch two rows of stitches, one at 10mm from edge and one at 20mm from edge.

Then gather by pulling the bobbin threads (underneath ones) from each end to gather the fabric. If doing lengths of more than 1 metre, then stop, leave long thread tails, and start a fresh length of gathering threads to avoid gathering long lengths of thread which might break on you.

If your machine has a basting stitch it might look like " .___.___.___" on the dial however, I've never been that happy with machine basting for things like attaching slippery fabric to underlining, I've always done it with needle and thread to keep the two layers matching and not stretching/slipping. For example, stitching a piece of chiffon to a underlayer of satin, even pinning carefully, these two fabrics will slip under the machine foot so I'd always do it by hand.

If you have masses of fabric to gather, sometimes what is quicker is doing a large wide zig zag over a length of perle cotton (heavier than thread) at the 15mm seam, don't let the needle pierce the cotton though. Then you can gather the fabric along the perle cotton.

Sewing machine instruction manual often assumes a knowledge of sewing techniques that you may not yet have. I have the Vogue Book of Sewing on my shelf and refer to it often. Or Singer do a good range of sewing books too, its worth investing in a good reference book.

I also love www.patternreview.com, this is such an awesome website for dressmakers/sewing enthusiasts and you will find loads of helpful tips here.

Hope this helps you a little.

My needle won't move even with hand wheel. Feed dogs move. Bobbin turns. Bobbin winder is off. Did same thing last night then worked when I turned it on this morning. Quit with 6 inches left of 12 yard...


You have a gumed up basting device, You can try to fix yourself but should be taken to a bernina teck for a fix. Take the end cap/head cap/ side panel/ needle bar panel off. It is one screw on the left side.
Remove neddle
Find the needle bar
On the needle bar there is a black small pice, it is round and has a little tab that stitcks off it.
Pull the needle down and push/pull/wiglle soft on the small black tab.
There is a small pin inside that should clip into a hole in the needle bar.
This should get your machine sewing again but the basting device realy should be cleaned and adjusted, should be around $45-100.
Hope this helps.

Bernina 1090 Needle assembly stopped moving down


Hi,
There is a spring loaded catch on the needle bar assembly. It is designed to keep the needle bar from going up and down on command for basting. That way it can take fewer stitches while basting. Anyway, over time, with lint build up, use and not enough oiling, the needle bar clamp release can stick. It is located in the machine cover and hard to get at. It is located right at the point where the needle bar clamp (middle of needle bar) is. It looks pointed on top and about 3/8" tall and SHOULD be able to move front to back (as you are sitting at the machine. If you want to fix it your self, lay the machine on it's back to see up into the needle bar area, you can also see through the threading slot as well.to oil it with SEWING MACHINE oil (read not 3 n1 oil) and try to work it front to back until it breaks free and play with it until it springs back every time you push it. I hope this helps.

2020 rotary hook continuous one direction pfaff tiptronic 2020


You are absolutely correct - your machine doesn't come apart much because it is an electronic machine. There really are very few moving parts in modern sewing machines - and the electronics are better left to a technician who's been specifically trained.

It sounds as if your machine is no longer in time (needle rubbing the plate as it goes around if I'm understanding correctly). While not really a "major" repair, unfortunately with computerized/electronic machines, retiming your machine is something better left to an authorized Pfaff technician.

If the needle struck metal as you were stitching/basting, there may also be a rough spot/burr on the hook that your technician will be able to smooth off as well.

Hope this helps get you back up and running soon.

Happy stitching,

Long stitch!!


Hi teza...I assume that you have decreased your stitch length selector resulting in no change, indicating that the internal stitch length mechanism is either insufficiently lubricated, or truly broken If not broken, you can work the mechanism free by removing your needle, selecting the maximum stitch length and any non-overlock stich pattern, ie. straight or zigzag, fully depress your foot pedal so it runs at maximum speed, and methodically press and release the Reverse button/lever. After a minute of this, hand crank your machine while observing the feed dogs, and changing your stitch length. If your stich length is set to 0, your should observe your feed dogs moving vertically up and down with no back/forward motion, however, increasing as you lengthen your stitch length. Repeat the previous high speed work out until you notice full strokes of your feed dog...good luck my friend
