ABSTRACT:
The upper side of the sole plate in a sewing machine presser foot is formed with a transversely extending channel for the median portion of a guide which steers the needle during making of a row of stitches adjacent the edge of a marginal portion of a piece of fabric. To this end, the guide has two end portions which extend laterally beyond the respective sides of the sole plate and have downwardly bent tips one of which slides along the edge of a piece of fabric when the sewing machine is in use. The guide can be moved longitudinally to place its end portions at selected distances from the respective sides of the sole plate. A male detent member on the sole plate normally engages a selected graduation of a notched scale on the central portion of the guide to maintain the guide in a selected position. The tips of end portions of the guide are located at a level slightly above that of the underside of the sole plate.
