Types Of Sewing Machine Stitches
If you include all the hand stitches, sewing machine utility stitches, sewing machine decorative stitches, serger stitches, and industrial manufacturing stitches, you have a bunch of stitches. On a moderately priced home sewing machine you will find twenty to two hundred different stitches plus variations in stitch length and stitch width as well as stretch factors. A top quality home sewing machine will have eight hundred to a thousand different stitches. Many sewing machines include multiple sets of alphabet letters.
Sewing machines are not all the same. Even sewing machines that look alike, can be very very different. Sewing machines vary in the stitches they offer as well as how they make those stitches.
The least expensive modern sewing machine is described as a mechanical sewing machine. These machines depend on an AC electric motor to drive shafts, gears, levers, and belts. Across the top, a series of mechanical devices the needlebar. Across the bottom, another shaft drives the hook and feed systems.
Mechanical implies levers and gears working together. When you examine the insides of a mechanical sewing machine, you see a large gear with strange ridges and valleys around it. Then you see levers that rub against or run along the edge of this large gear. This motion conveys this motion to the needle bar enabling the bar to create a variety of stitches.
Cam tracker alignment are adjusted by surface mounted dials, buttons, or levers. The position of the cam tracker lever determines the stitch produced. The position of the stitch selector lines up the tracker to form the selected stitch. If it gets out of line, it will fail to produce the desired stitch. To fix this, adjust the stitch selector connection on the cam tracker and align it with the proper groove on the cam gear. Also look closely to make sure the cam gear has not cracked or broken.
Electronic sewing machines use electronics to control the power drive system and the stitch selection system. Note many machines are blends of mechanicals and electronic technologies, and others are blends of electronics and computer technologies. Fully electronic sewing machines use electronic circuits to manage motor output giving the sewing machine greater torque, increased consistency, and smoother sewing.
Electronic sewing machines significantly improve the smoothness, dependability, and ease of sewing machine use. Many more stitches are offered by electronic stitches.
The next level of sewing machines is called computerized sewing machines. These machines have revolutionized the sewing machine industry with huge advancements in technologies. These machines offer far more stitches while making sewing smoother, easier, and more dependable. The computer technology has transformed the sewing machine like so many other products. It controls super quiet DC pulse motors, programs amazing stitches, and gives the user greatly expanded creative potential. A touch of a button or a spot on a touch screen yields up to a thousand different stitches.
Mechanical sewing machines use buttons, dials, and levers to select stitches.
A button is used on an electronic sewing machine or stitch selection.
On a computerized sewing machine, press a button on the computer keypad or touch the selection on a computerize touch screen.
You can get a handle on your stitches with this little exercise. Make your own stitch selection reference book. Cut as many 5 by 7 pieces of plain fabric as you may need. Select one stitch at a time, and sew one seam across the piece of fabric. Sew similar stitches (utility, decorative, etc.) on each piece but spread out for neat appearance. Repeat the process for every stitch on your sewing machine. If you only have a few stitches, try sewing a variety of lengths and widths. This is an inexpensive and practical way to really get a handle on all your stitches.
Grasp the full potential of your sewing machine. Learn every stitch on your machine. Master the selection, settings, and use of each stitch. Then you will have real confidence sewing with your sewing machine.
