A sewing machine uses thread to sew two or more layers of material together. As simple as that may sound, the process is almost magical to watch. Even the most basic machines can do straight stitch, zigzag stitches and some decorative stitches. A little more amazing, the process is nearly identical for each type of stitch. I amazed many people when they ask “ What different does a sewing machine do to make different stitches? ” The answer is “ Very little. ”
ow a sewing machine makes stitches
When you see the sewing machine working on the sewing bed, it seems as if the needle is feeding the thread down through the hole and up again. It is the action that takes place under the sewing bed that creates a stitch. There, a hook rotates and carries the thread from the bobbin within the thread loop passing through the needle. The needle guides the thread through the material layers and the bobbin thread se.res it so that they clung together the layers.
So, what does a sewing machine different if you use a zigzag setting? Only the top part of the machine changes direction to create the zigzag. The lower part of the machine always remains stationary. The machine will shift the spindle back and forth to make the stitches go back and forth. Depending on the settings you choose, the distance the needle travels back and forth determines how wide the zigzag stitch . The stitch length determines how tight the stitch is.
In general, a mechanical sewing machine has a motor that causes the parts of the machine to move to make stitches. You choose the stitch and the width and length by turning a knob. A computer-controlled machine can do much more with a lot less effort on your part.
