Abstract
A cloth edge control device for a sewing machine includes a pair of rollers, an optical sensor, and controller. The pair of rollers are arranged near a needle location in such a manner that the rollers are rotating about an axis perpendicular to a direction in which a cloth material is fed, so as to be pushed against the cloth material. The optical sensor is adapted for detection of the cloth material at a plurality of points on a line along a direction intersecting with the feed direction before the needle location. The controller detects the position and curvature of the edge of the cloth material according to a light intercept signal from the optical sensor and rotates the rollers independently of each other according to the position and curvature thus detected.
