Most modern embroidery machines are computer controlled and specifically engineered for embroidery. Industrial and commercial embroidery machines and combination sewing-embroidery machines have a hooping or framing system that holds the framed area of fabric taut under the sewing needle and moves it automatically to create a design from a pre-programmed digital embroidery pattern.
Depending on its capabilities, the machine will require varying degrees of user input to read and sew embroidery designs. Sewing-embroidery machines generally have only one needle and require the user to change thread colors during the embroidery process. Multi-needle industrial machines are generally threaded prior to running the design and do not require re-threading. These machines require the user to input the correct color change sequence before beginning to embroider. Some can trim and change colors automatically.
A multi-needle machine may consist of multiple sewing heads, each of which can sew the same design onto a separate garment concurrently. Such a machine might have 20 or more heads, each consisting of 15 or more needles. A head is usually capable of producing many special fabric effects, including
