<p>A sewing machine pressing leg and an adjusting device therefor is disclosed, wherein several rollers are disposed under the pressing leg to contact a sewed material so as to censure the smoothness of material feeding and avoid crimp of the sewed material. Therefore, the seam is kept straight, smooth and beautiful. The contact area between such pressing leg and sewed material is larger so that a smaller pressure is applied to acquire better material pressing effect so as to avoid a pressing track left on the surface of the sewed material by the rollers. The pressing leg is mounted on a transverse and a longitudinal adjusting bar by means of which the pressing leg can be adjusted to an optimum position to press the sewed material and facilitate the sewing operation. <IMAGE></p> |
