How To Improve Performance Of Sewing Machines

Sewing machines can run smoothly and reliably for years to come if they are properly
setup, and regularly oiled and serviced. But, another important thing to remember is that
the bobbins and needles you use, and the winding of bobbins must be perfect for flawless
stitching, and avoidance of any sewing problems and damage to the machine.
Bobbins
You need to use the right kind of bobbins that suit your machine type. Your machine
manual states the kind of bobbin your machine requires. Make sure you use only the
mentioned bobbin type. Any kind of changes to the shape, size, type, or material of bobbin
will affect not only the stitch, but may also damage the machine. Also, make sure you get A-
grade quality bobbins from reliable and trustworthy metal bobbin manufacturers in
India like Trim Engineering Services.
Needles
Just as much as the right kinds of bobbins are required, equally important is the usage of
the right needles. The wrong size of needle can result in needle breakage, thus damaging
the machine and causing safety hazards for the operator. Every fabric requires a different
needle size to be sewn. Going up or down even one size can affect the stitch and functioning
of the machine. Needles are sized from 8 to 18. A size 9 to 11 needle is appropriate for
delicate and lightweight fabrics like chiffon, organza, and silk. A size 14 needle is best for
medium-weight fabrics like cotton, linen, and suedes. And, a size 16 needle is designed for
heavy-weight fabrics like denim and velvet.

Bobbin winding
Once the appropriate bobbins and needles are selected, it is crucial that you wind the
bobbins properly. Improper winding may disrupt the timing of the machine, break needles,
create downtime from clearing tangled thread, and require expensive machine repairs. To
avoid all of this, it is important to wind bobbins properly, or use pre-wound quality
bobbins. This will not only bring smooth finishes, but will also increase efficiency of the
sewing operations. If not properly wound, there may be multiple issues you may have to
face.
Threading the machine
Bunching thread under the fabric – When you have a perfectly straight stitch on the top of
the fabric, and thread bunching at the bottom, you may tend to think that the bobbin is not
wound properly. But, the truth is that there is no tension on the upper thread. To resolve
this, you need to raise the pressure foot lifter and rethread the machine. Next, you will need
to raise the take-up lever and needle to the highest position as per your machine’s manual.
This way, you will have the right tension.
Apart from making sure that all of the above is appropriately done on your machine, there
are a few other tips you must follow too. Experts recommend that you replace your needles
every 16 hours of usage. This will avoid the needles from breaking, bending, and being
damaged. Also, remember not to force the fabric under the feed dogs by pulling it from
behind. This will result in messy stitching, and can even break your machine. Let the fabric
move smoothly on its own.
