How Does a Sewing Machine Sew?

How Does a Sewing Machine Sew?

Most home sewing machines sew with two threads. An exposed thread fits through the needle’s eye. Another thread, called the bobbin thread, is wound on a bobbin, or tiny spool, beneath the needle.

Gears move the needle up and down, and turn the bobbin round and round. To make a stitch, the needle pushes the top thread down through the fabric.

A hook on the bobbin catches the top thread and loops it around the bottom thread. The needle rises and the stitch tightens. A toothed plate called a “feed dog” pushes the fabric ahead, and another stitch begins.

Home sewing machines are designed for one person to sew individual items while using a single stitch type.

In a modern sewing machine the fabric easily glides in and out of the machine without the inconvenience of needles and thimbles and other such tools used in hand sewing, automating the process of stitching and saving time.
