Sewing Machine Structure and Types Vocaubulary
Sewing machines are widely used in a variety of industries. In addition to clothing production, they can also be used for fabricating furniture, automotive upholstery and a host of other products. Sewing machines come in a range of shapes, sizes and prices, which often have common components. Understanding the structure and types of sewing machines can help you make the best purchasing decision.
Overall Structure
The overall shape of a typical sewing machine is often box-like, with a knee-operated foot pedal to control speed, an adjustable stitch length and width, and a removable bobbin case to wind threads. Sewing machines can typically handle a wide array of fabrics, including leather and canvas. Many sewing machines come equipped with a range of presser feet, including a standard foot, zipper foot, blindstitch foot, satin stitch foot and buttonhole foot.
Threading
Threading a sewing machine requires passing thread through a series of guides, tensions and hooks. This is usually done by using thread guides on the machines arm, along with a threading chart that outlines the correct direction in which to thread the machine. The thread should be tightened before beginning to sew, and the machine will usually have markings to indicate the proper tension levels.
Types of Sewing Machines
The most common type of sewing machine is the straight stitch machine, which is the most basic model. This type of machine is used for straight-line stitching, such as for hemming and topstitching. A zigzag stitch machine is designed for more intricate projects, allowing users to control the width, length and angle of the stitch. Another type is the overlock stitch machine, also known as a serger, which is used to neaten the edges of fabric by creating a seam. Computerized sewing machines are the most expensive and advanced models, featuring a digital display and programmable memory to store your settings.
Safety
Before using a sewing machine, you should always familiarize yourself with all safety features, as these machines can be hazardous. Many machines come with an electric foot pedal, which should be used to power the machine on and off. Additionally, you should check to ensure the needle is properly installed and tighten the thread in the bobbin case. It is also important to unplug the machine when doing any repairs to avoid potentially hazardous electrical shocks.
Sewing machines are often essential for garment manufacturing and a range of other projects. Before purchasing a machine, it is important to understand the main components, types and safety features. Knowing the structure and types of sewing machines can help you make an informed decision, so you can select the best machine for your needs.
