Abstract:
The present invention relates to a sewing machine, specifically a long-armed stitcher. The present invention includes a computer device that may store pantograph patterns therein. The data including the pantograph patterns may be sent to projection units associated with the sewing machine head of the long-armed stitcher. The projection units use projection elements to project the pantograph patterns on the fabric to be stitched, allowing an operator of the stitcher to trace the projected pattern with a needle associated with the sewing machine head. Measurement devices associated with the sewing machine head determine head movement and alter the projected pattern accordingly such that the needle of the sewing head may continue to follow the pantograph pattern despite the head having moved in order to trace the pattern.
