Abstract
Abstract An assembly comprising a presser foot and at least one graduated rule consisting of a plate hingedly secured to the sole portion of the presser foot and extending prolongation of said sole portion and in the same plane, the hinge axis extending in a direction transverse to said sole portion, the main advantage being that the presser foot is equally suitable for satin stitch, buttonholing and normal or straight stitch sewing operations without changing the presser foot when passing from satin stitch sewing to straight stitch sewing.
