How many stitches does a modern sewing machine have? For the first hundred years, the sewing machines only had straight stitches. Today, sewing machines are very different. Today there are whole sets of stitches including, decorative stitches, alphabetic lettering, utility stitches, and over casting stitches. Today sewing machines boast twenty to a thousand different stitches. Most machines enable variations of length and width.
How many different types of sewing machines are there? It can be a challenge to understand all the subtle differences and all the major differences. Stitches vary not only in number, purpose, and design; they are made in different ways.
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.
The mechanical devices that produce stitches are in the hundreds. Levers (cam trackers) rub against a cam gear with grooves and bumps that cause these levers to move back and forth. This motion transfers across the machine to alter the needle bars movement. The result is a needle bar that rises and falls in various positions left to right to form desired 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.
One step above the mechanical machine is a class of sewing machines that applies a variety of electronic devices. These devices are often used for better stitch selection. Usually, the electronics are used to improve power control. There are blended machines. Some blend mechanical machines with limited electronics. Others use loads of electronic devices even blending with computerized parts. Electronic sewing machines significantly improve the smoothness, dependability, and ease of sewing machine use.
Stitches are selected with electronic buttons that control the production of stitches. Electronic sewing machines usually offer more different stitches and more dependable sewing.
Computerized sewing machines use the most advanced technologies to produce the greatest number of different stitches, smoothest sewing, and most dependable operations. Computer input is made either by pre-programming, touching buttons on the computer keypad, or a touch screen. The computer takes the signal and manages a set of DC pulse motors to create and manage stitches. It is common for computerized sewing machines to offer hundreds of different stitches.
Mechanical sewing machines use buttons, dials, and levers to select stitches.
An electronic switch is used in electronic sewing machines to select stitches.
Select stitches on a computerized sewing machine by touching a touch screen, pressing a keypad, or pressing a button.
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.
Now you know how to select the various stitches on your sewing machine. You also have a visual example of each stitch.
