Bobbin Tension Issues On Cowboy 3200

[vikingusa1]

I am having another issue with loops showing on the top of the leather. I am using a Cowboy 3200.

I think the issue may be the bobbin tightness but not sure. Sometimes the thread coming up from the bobbin is so tight it won't pull out.

At first we had the bobbin in upside down but we sewed with it like that for quite awhile (2 weeks) and then i had to change the bobbin out and put it in still upside down and now its doing top loops.

I have fiddled with EVERYTHING and checked the manual over and over again. I just can't figure this one out.

Can someone please shed some light on what this might be?

Thanks!

Loosen thebobbin tension a little at a time sew and check and you should be able to get back to sewing in no time.

If the machine is threaded properly, you have the correct needle and thread combination then tension could be an issue.

Do you know what the top and bobbin tensions are, have you measured them, can you pull them easily by hand?

Is there a take up spring on that machine?

Top loops are usually a sign of to little bobbin tension or to much top tension. Check to make sure the bobbin thread is coming out under the tension spring, and that it has slight and even resistance. If the top tension is to tight ,your top thread will lay straight on top, with bottom thread showing at each stitch. It is a balancing act to get the knot to stay in the center of your work. If your bobbin tension seems ok, then back your top tension way off and sew a few stitches, increasing the top tension by 1/2 turn and trying again until your stitches are pulled up inside on the bottom and not looping on top. Also check that your top thread didn't jump out of the discs and jammed in or around something it shouldn't have. Gump

I think its the bobbin. We have been sewing the same material, same needle, thread, etc. for two weeks now. We filled the bobbin, started the sew and we started having the problem? When I first set up the machine I had the same problem and worked it out by loosening the primary tension. The boobin tension is perfect, then the thread binds on the bobbin? Could we be filling the bobbin wrong? or are we loading the bobbin the wrong way? (Bobbin should run Counter clockwise is that over or under the bobbin?)

Thanks sooo much for your time guys! learning something new is always a challenge! But, one I love!

Best,

Dave,

Gump gave you some good ideas,the bobbin thread needs to go over the top as it pulls so it doesn't slip out of the tension as your sewing.Also double check the needle thread as once in a whaile it canslide behind the 2nd tension & cause the top thread to be too tight.

Also, The take up spring was rubbing on the side of the machine. Its not performing a full stroke up and down. I worked that out now have to adjust for a 3/8" stroke.

Hey Bob,

I worked it out the last time we spoke. Something changed? Like I said we have been sewing for a couple of weeks withe same set up?

We are thinking that when we wind the thread on the bobbin that something is amiss. at first (weeks ago) it went on unevenly when threaded but it sewed fine. Now when it goes on neatly it is catching and pulling when we sew. AND the loops are still on top.

We have played with the tension in every way possible, we have loosened the little feeder plate on the bobbin and back, we have re-threaded the machine to make sure we didn't miss a step, and the tensions are as loose as we can make them. If we go tighter it doesnt work.

THe thread is binding on the bobbin and that is the biggest problem along with the loops on top.

If I knew what your thread tension was I could compare it to my 4500.
