Abstract
A fiberoptic bundle has one end disposed in the bed of a sewing machine in opposition to the stitch formation region below the throatplate. A strobe light for periodically illuminating the region and a camera for recording visual images of the region are coupled to the opposite end of the fiberoptic bundle. The end of the fiberoptic bundle within the sewing machine bed may be provided in guidepaths for viewing the stitch formation region from different viewing directions, preferably 90.degree. apart. A load cell is disposed on the side of the sewing machine for recording tension transients in the thread en route to the needle.
