Abstract
A method and apparatus for automated assisted sewing of an oversized, digitized sewing pattern, using a fabric retention mechanism and an automated sewing machine positioning mechanism. The sewing machine positioning mechanism is controlled by an actuator and provides for two dimensional positioning of a sewing machine with respect to the fabric retention mechanism. The oversized sewing pattern is segmented into pattern segments and the pattern segments are sewed sequentially in accordance with a selected order, with the fabric being repositioned after each segment is sewed. Cut points for pattern lines on the border of each pattern segment are matched by start points on the adjacent border of a subsequently sewed, adjacent pattern segment. A pattern program adjusts the pattern lines of each subsequently sewed segment to provide for continuity and alignment of the pattern lines which cross the borders between pattern segments.
