Sewing machine

A sewing machine is a mechanical (or electromechanical) device that joins fabric using thread. Sewing machines make a stitch, called a sewing-machine stitch, usually using two threads although machines exist that stitch using one, three, four or more threads.

Sewing machines can make a great variety of plain or patterned stitches. They include means for gripping, supporting, and conveying the fabric past the sewing needle to form the stitch pattern. Most home sewing machines, as with many industrial machines, use a two thread stitch called the lockstitch. Some older machine types are chain stitch machines and sergers.

The fabric shifting mechanism may be a simple workguide or may be pattern-controlled (e.g., jacquard type). Some machines can create embroidery-type stitches. Some have a work holder frame. Some have a workfeeder that can move along a curved path, while others have a workfeeder with a work clamp.
