The Secret Behind How Wholesale Sewing Machines Work

If you're looking for a wholesale sewing machine, there's almost as many available as there are tailors. Nowadays wholesale sewing machines have numerous features that can suit every budget, skill level and profession. You can pay anything from $50 to $5000, and can choose a specialty machine for one particular task, or a more general machine that perform various different functions.

When you consider that wholesale sewing machines were created back in the mid-1800's, they really are an amazing feat of engineering and technology. Take the loop stitch as an example. This is very simple to do by hand. You tie the thread onto the eye of a needle. You then push the needle and thread through the two pieces of fabric you want to sew together, pull it out the other side, turn it around and push it back up through the fabric again. The thread loops in and out of the fabric and holds them together. And yet trying to duplicate that stitch on a sewing machine is almost impossible. You'd have to work out how the machine could push the needle through, let it go, turn it around, and push it back again. Then the machine would also have to pull the full length of the thread through the material as well. It doesn't sound as simple as doing by hand, that's for sure!

So the only solution was for the sewing machine to perform the stitch in a slightly different way. A sewing machine needle has the eye at the point of the needle instead of at the top end. A needle bar holds the needle, and is driven up and down by the motor. The sharp end of the needle passes through the fabric and is then brought back up through the fabric again. In the process it leaves a small loop of thread on the bottom side of the fabric. Underneath, another mechanism grabs the loop that's left behind. It then wraps the loop around another piece of thread, or makes another loop in the same piece of thread.

The good thing about wholesale sewing machines is that they don't just do loop stitch. You can use one to perform lock stitches, chain stitches, and basically just about any stitch that would normally be done by hand.
