A sewing machine consists of four basic mechanisms: a take-up mechanism, a needle-motion mechanism, a material-feeding mechanism, and a bobbin. Its proper operation requires a delicate balance of these mechanisms. This paper introduces a computer-simulation model that represents these mechanisms and uses the model to predict the kinetic behavior of sewing machines. Based on the simulation. a quantitative understanding of
Industrial sewing machines differ from traditional consumer sewing machines in many ways. An industrial sewing machine is specifically built for long term, professional sewing tasks and is therefore constructed with superior durability, parts, and motors. Whereas traditional sewing machines might include nylon or plastic gears, an industrial sewing machine's gears, connecting rods, housings, and body are typically constructed from high-quality metals, such as cast iron or aluminum. Beyond that, industrial sewing machines are made to handle thick materials such as leather, produce faster stitch rates, and incorporate stouter, more positive feed components than do their consumer equivalents.
Sewing Machine Feeds
Different industrial sewing machines offer several ways to feed the material. Typically, industrial mini sewing machines that deliver numerous feed capabilities are more expensive. The main types of feed mechanisms are:
Manual feed: The feed is controlled entirely by the worker, who can do delicate, personal work such as shoe repair, embroidering, and quilting. On industrial overlock sewing machines, it is sometimes necessary to remove the feed dogs to obtain a manual feed.
Yet another important feature is the size and speed of the industrial embroidery sewing machine. More expensive machines will be able to sew more stitches per minute. Larger machines provide a larger clearance area under the foot and bigger bed size.
