ABSTRACT:
Apparatus is provided for digitizing a pattern by utilizing the computer controller and motor driver of an x-y table used in an automatic sewing machine. A manually operated control stick is installed on the machine and connected through the controller to send command signals to the motor drivers. A viewer is mounted on the machine to project a pattern, which is placed on the work surface of the x-y table, onto a small screen. The operator may then, through the use of the viewer and the control stick, move the x-y table through the desired pattern. Such movement is recorded in the computer for use in generating a control tape for the specific pattern.
