Make sure the chain stitch thread is threaded exactly as it should be, make doubly sure the thread comes off the bobbin vertically and runs through all eyes smoothly. Any faults in the threading causes extra tension at the needle despite what the tension is set on.
If this is not the cause then the needle depth and the looper timing needs checking.

You need to do a tension assembly test. Normal 0 MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman";} Tension assembly test. To do this test. Pull the thread through the tension assembly and test it to make sure the tension is working correctly.
(To do this test, adjust your tension setting to normal or medium or 5 or something in the middle. Raise the presser foot and pull the thread through the tension. It should pull easily!! Lower the presser foot and pull the thread. It should pull noticeably harder.)
If it doesn’t work this way then you probably have a piece of thread or lint stuck inside the tension discs. To remove it, turn the tension to 0 zero and raise the presser foot.Using a small screwdriver, open the space between the discs and spray with canned or compressed air. The stuff should come out. Do the tension test again to make sure you got everything and then try sewing again.

SOURCE: euro-pro 464xc bottom tension loose

Welcome to FixYa!

Loose bottom stitches come from the top, not the bottom. Seems weird, but that's the way sewing machines work.

The dial tension should be set at the mid range and make absolutely sure that you have the machine threaded correctly. Both things will cause a sloppy bottom stitch.

Thanks!

If you find my solution helpful, I'd appreciate a FixYa rating....

SOURCE: Tension problems

Possibly you have the bobbin in upside down and its turning the wrong way. Read manual. If you have done everything the manual says then it must be a mechanical issue such as the small thread take up spring or maybe the tensioner discs are dirty. Timing slightly off or there is a burr on the hook that catches the thread. Have a tech look at it.

Adjusting tension on overlocker


overlockers and sergers are annoying in that every time you change materials and threads they must be re-tensioned.

Get a scrap piece of material. Thread your machine correctly according to the instructions in your manual. If no manual most sergers are threaded, upper looper, lower looper then needles from right to left. Make sure you thread with the presser foot UP.

You want to balance the stitches Begin by adjusting the looper dials, you want them to meet right at the cut edge. Then adjust your needles. Keep doing test seams until you have them balanced. If you are a novice... try threading with each thread point having it's own color. That will help you identify which thread is giving you fits.

Have fun.

Tension to loose and missing stitches


SKIPPED STITCHES ON A SERGER
1. Is the needle bent or worn--replace
2. Is the needle inserted correctly into the needle holder--check needle
3. Is the Serger threaded correctly--rethread
4. Is the presser foot pressure right for the fabric--adjust

use a scrap piece of fabric to sew on as you adjust the tension
when the tension is to loose adjust one number higher till stitch
looks good

here's 2 links for a manual one is a hardcopy & the other is a

What are the settings for overlocking stretch fabrics


For knits with lycra in, you are best to thread up four threads and seam with the 4 thread marrowing stitch like this, preferabbly with ball point needles in your overlocker, size 80. Use cones of polyester thread, 3,000 metres or 5,000 metres rather than normal thread. (Although if you have trouble matching thread colours you can use a small reel on the left needle as this is the thread that will show on the right side of the garment.)

11_7_2011_5_17_44_am.jpg


Start with your machine tensions on 5, both needles in and threaded, stitch length of 2.5 and no differential (set it on zero) and test stitch. Using stretch or ballpoint needles is a good idea too to avoid any deflection and skipped stitches. Then practice serging on some fabric scraps, double layer and look at the seam, if it is tunnelling (pulling up the fabric), then move the cutting blade to the left. Test again and if still tunnelling, then loosen off the tension on the top and bottom loopers by a half number and test again.

If the opposite is happening and the threads are looping off the edge of the fabric, then move the cutting blade to the right to trim less fabric, test again. If still too loose, then tighten up the top and bottom looper tensions by a small amount and test again.

You want the seam to lie flat, the two looper threads to meet right on the cut edge and the needle thread to be just visible from the right side when you press open the seam.

There is always a small amount of adjustments needed on an overlocker when setting up for a new project as every fabric will behave differently. Don't tighten up the tension on the needles much past 5 though, or you may get thread breakage.

If you find that the seam is flutting then you can use the differential feed to adjust for this too.

There is some good overlocking info on Debbie Cosgroves website, www.sewing.about.com, with images which may help too.

I am trying to do a rolled hem using a singer ultralock 14sh654. Do I disengage the knife? The stitches are uneven and some are quite loose no matter how much I adjust the tension. I am positive I...


no, you need the blade in place and cutting to give an even cut fabric edge. Set up for a three thread using the right hand needle, take out the left hand needle. move blade over to the right so it is cutting wide. Most overlockers there is also a thread finger you need to change on the foot, or a little lever you flick to move this finger forward into the stitching area. Check this on your manual as each make is a bit different.
If you can source it, put wooly nylon thread into the upper looper (knot it onto existing thread and just chain it through, the knot should go through the looper eye fine). Now turn the tension on top looper down so it is looser and tighten up tension on bottom looper, so needle 5, top looper 2 and bottom looper about 7.

Now test serge, the fabric cut edge should be wider than the overlocking seam so the fabric rolls under inside the stitching. Adjust the two looper threads so that this is happening, you want the bottom looper thread to nest right up against the needle stitch and the top looper thread to wrap all the way around too.

Once you've got this happening, turn the stitch length down to 0.5, to close the stitching right up. On some fabrics you'll need to adjust the differential feed too if the fabric is "waving" a bit.

Uneven stitches or sometimes loose when serging could indicate that one of the tension devices is faulting, so if this machine is not new and its doing this, it could need a service. Can you get a regular smooth three or 4 thread seam out if it???

It is always good to just recheck the threading path, make sure the thread aerial is up and that a thread hasn't got caught back on the thread stand somewhere if you're getting something wonky happening, threads stream off overlocker cones through the machine so anything wrong in the thread path will throw off the stitching.

I want to just make a straight stitch like it was a regular machine


if you are using an overlocker you can't replicate the straight stich as it has no bobbin for the underneath stitch. Even if you get a stitch like that accidently, it will pull apart because the 2 threads are not linked in any way; sorry

I've just got janome 634d serger, how can i make the bottom of a T-shirt ? Thank you so much


If you want the bottom of the T to look like RTW with the double row of stitching, you cannot do this on a serger.

You can achieve the effect by using a twin needle, two spools of thread, bobbin and a straight stitch.

Make sure the double/twin needle will pass through the presser foot and opening in the needle plate below the presser foot.

Practice on a double layer of a scrap of the T shirt material as the tension may need to be slightly looser than the normal setting.

Brother XL2230 Elastic Overlock function not working properly


First of all check your needle size and utility, for the tension machine it must be the same on top and bottom example pull the top thread and the lower thread they must be the same.
When sticthing the elastic you must devide the amount of elastic versus the fabric : dise the amount before stiching
Hope this will help
Good day
