Abstract
An automatic quilting machine for use in stitching individual selected patterns into a large fabric such as a bedspread or quilt. The bedspread or quilt is stretched on a large metal frame which is mounted on a table which can be moved in the X-direction, the Y-direction, or any X-Y combination direction, either through a manually operated automatic joystick or mouse or through an automatic remote control directed by a computer. The sewing machine function is controlled by one computer connected to the sewing machine head and the quilting table motion in the X-direction, Y-direction, and X-Y direction is controlled by a separate computer. When it is desired to change a sewing machine computer function such as a stitch or accessory functions such as trim, the sewing machine computer can be independently reprogrammed. When it is desired to change the pattern, the separate computer controlling the X-Y table movement direction can be independently reprogrammed. It is not necessary to reprogram both funcions which is an enormous task. Instead, only one of the functions needs to be reprogrammed, thereby greatly simplifying the process.
