Mechanical Sewing Machines

Mechanical sewing machines are basic entry level models, with limited features and stitches. Models can have a 4-step or 1-step buttonhole facility and may have an automatic needle threader. The can sew most fabrics and be very robust, however lower priced models in this category are better suited to sew light to medium-weight fabrics. Generally they will have a convertible free arm which is used to help sew around sleeves and trouser legs. 

There are two types of bobbin systems used for mechanical models. One is a front loading system where the bobbin is inserted into a bobbin case and then slotted into a front opening on the arm of the machine. The second type is a top loading, full rotary hook system for an easy jam proof operation. This system also offers a clear view cover for the bobbin area, which allows for monitoring of the bobbin thread level.
