What are the 2 types of sewing machine?

Answer 1

There are many more than two types of sewing machines, but the two most common are the Lockstitch and the Chainstitch. A chainstitch machine uses only one thread, which is looped around under the fabric and around itself, forming a "chain" under the fabric. A lockstitch machine uses two threads - one on top and one beneath the fabric being sewn. The upper thread is passed through the fabric by the needle and is looped around the bobbin, which contains another small spool of thread the bobbin thread "locks" with the needle thread, giving the lockstitch its name. Lockstitch looks the same on both sides of the fabric.

Types of Sewing Machines

Each machine makes a basic running stitch the same way, with two sources of thread. The top needle takes the thread down into the fabric. It is caught and looped via the bobbin apparatus and then pulled back up. The "feed dog" (a rough edged surface underneath the fabric) moves it along and the next stitch begins. Everything else is different.

Mechanical Sewing MachinesA mechanical sewing machine is controlled by a rotary wheel. Any adjustment like the tension or the length or width of the stitch is made by moving a dial. These machines are very basic and tend to be less expensive than the other sewing machines. Electronic Sewing MachinesAn electronic machine differs in that there are some functions that can be accomplished by pushing a button. A machine can have a number of motors for various duties and they are run via electricity. Computerized Sewing MachinesAs sewing machines became more complex, more of these motors were added. A computer then coordinates all these functions. Think about a repetitive sequence of stitches being programmed, so you no longer have to replicate these movements over and over again.
