Professional Computerized embroidery machines are specialized machines that can create embroidery from computerized designs.
Such machines exist for the home market, for the small independent professional and for mass production.
The computer directly controls several different motors, which precisely move the needle bar, the tensioning discs, the feed dog and other elements in the machine.
The computer drives the motors at just the right speed to move the needle bar up and down and from side to side in a particular stitch pattern.
These machines have a motorized work area that holds the fabric in place underneath the needle assembly.
They also have a series of sensors that tell the computer how all of the machine components are positioned.
The sewer simply loads a pattern from memory or creates an original one, and the computer does almost everything else.
It can be argued that computer-controlled embroidery machines are older than computers, i.e. models made between the two WWs used punched paper ribbons for control.
Before computers were affordable, most embroidery was completed by punching designs on paper tape that then ran through an embroidery machine. One error could ruin an entire design, forcing the creator to start over.
(So in the old days I would have been a PUNCHER!!)
According to Wikipedia and other sources, the first modern day computer controlled sewing machine was built by Orisol in 1987 for making shoes, i.e. much later than embroidery machines.
