2. 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 Machines : A 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 Machines : An 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 Machines : As 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. Nice!
