Garments Industry Sewing Machines | Some Essential Sewing Machines | Image & Short Introduction.

A device which is used to stitch fabric and other material with thread is called sewing machine. Most of the garments what we wear are sewn by sewing machines.

Sewing Machine is used for applying stitch in the apparel. Various types of stitching are done by the sewing machine. Depending on the stitch types, Sewing machines are classified. On the other hand sewing machines are classified according to their structure.

Types of Sewing Machines:

Each machine makes a basic running stitch the same way, with two sources of threads. 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!
