Sewing machine - Loops on the Bottom of the Fabric
We get quite a few calls on this. It is a situation that can, and does, affect any brand of machine. I added this information here to help you understand the situation. It may also save you some trouble if you are sewing at some odd hour. (Not that anybody does that).
When seeing this, people tend to think that there is a problem with the bobbin thread. This is usually NOT the case. About 90% of the time, the problem is with the top thread. If you see this, check the following, but if you are not comfortable in performing any of the actions that follow, do not proceed - call your local service person for further advice.
Sometimes it is possible to see into the disks and remove any obstruction.
You MUST be careful here, because machines have a little "take-up" spring in this area, and forcing this area could damage the spring. Something like a toothpick could be used to remove any lint. Be very careful with metallic objects, like pins, because they could scratch the disks and result in shredding thread.
Do the above test again.
If this is not successful, then call your local service person for further advice.
People like to blow the lint off their machines. They remove the bobbin cover, or the needle plate, then huff and puff, and blow the lint in. They may even resort to canned air, or an air compressor.
Lint is a problem. What happens is that any lint, dust, threads, etc. get blown into the working mechanism of the machine or serger. Lint attaches to the moving parts, absorbing the lubricant needed for smooth operation, and creates extra wear on those parts.
The machine may look clean from the outside, making it appear as though servicing is not needed but this is not the case. When it is time for a full cleaning, removing all the extra lint and lubricant increases the time, and the cost, for repair.
What to do - use a brush and/or vacuum to remove lint, rather than blow it into the machine. A mini vacuum attachment that attaches to your regular vacuum hose is available at SEW for IT! This tool is very useful for removing lint from sewing machines and sergers as well as for cleaning computer keyboards.
