A bobbin is a spindle or cylinder, with or without flanges, on which wire, yarn, thread or film is wound. Bobbins are typically found in sewing machines, cameras, and within electronic equipment.
Is there a spindle on a sewing machine?
Anatomy of a Sewing Machine
There is always a spindle (A), to hold the thread. There is usually a tension guide (B) and a thread guide (C), sometimes more than one. The thread usually passes down through the tension disks, which are hidden in the front of the machine (D).
What tension should my sewing machine be on?
The dial settings run from 0 to 9, so 4.5 is generally the ‘default’ position for normal straight-stitch sewing. This should be suitable for most fabrics. If you are doing a zig-zag stitch, or another stitch that has width, then you may find that the bobbin thread is pulled through to the top.
Where do you rest your feet when sewing on a foot powered sewing machine?
Keep fingers several stitches away from stitching line; keep them flat on the machine to the sides of the presser foot. The presser foot must always be in the “down” position for sewing.
What are spindles used for?
A spindle is a straight spike usually made from wood used for spinning, twisting fibers such as wool, flax, hemp, cotton into yarn.
What is the purpose of the bobbin winding spindle?
When To Use: Bobbin winders, whether built into the machine or a portable machine, help to wind the thread on the bobbin and help to distribute the bobbin thread evenly so that it will be compatible with the tension of the top sewing machine thread.
Why is my needle not catching the bobbin thread?
First, make sure the bobbin-winding spindle (located on top of your machine) has been pushed back to the left for sewing. If it is not in the correct position, the needle will not go down and pick-up your bobbin thread. … If the timing is out, the needle thread is not meeting the bobbin thread in time to form a stitch.
Why does my sewing machine keep getting jammed?
However certain you are that the problem with the machine is most likely due to a huge tangled mess of thread in the bobbin underneath the fabric, the most common reason for the jamming is usually the lack of sufficient tension in the upper thread.
Why is the thread bunching up when I sew?
Your Thread Tension Is Too Tight
Sewing machine manufacturers suggest that you don’t mess with your bobbin thread tension too much, but you should adjust your upper thread tension if you keep getting bunched up thread underneath your fabric. If your tension is too tight, it can pull your thread and break it.
Why is my thread bunching underneath?
A: Looping on the underside, or back of the fabric, means the top tension is too loose compared to the bobbin tension, so the bobbin thread is pulling too much top thread underneath. By tightening the top tension, the loops will stop, but the added tension may cause breakage, especially with sensitive threads.
Why is my bobbin not winding?
If your bobbin does not wind quickly and smoothly when you press on your foot pedal, your bobbin winder might not be fully engaged. This can cause uneven winding. Make sure you push your bobbin pin all the way over or loosen your bobbin wheel completely to engage your bobbin winding mechanism.
What tension should I use for cotton?
Cotton requires a moderate tension setting, usually between three and four. Always start adjusting your tension settings with your upper tension.
How do I know if my bobbin tension is correct?
The thread should unwind just slightly and the bobbin case should drop an inch or two. If the thread unwinds without resistance and the case slips to the floor, your bobbin tension is too loose. If the bobbin case doesn’t budge, your bobbin tension is too tight.
What tension should I use for thin cotton?
Use size 70/10 for really thin cotton like voile, size 80/12 for light to medium weight cotton, and 90/14 for thick cotton like denim.
