    摘要: For a hem stitching operation with a sewing machine having a needle vertically reciprocating and also laterally swingable, a hem stitching presser foot is detachably mounted to a lower end of a presser bar of the sewing machine. The presser foot includes a brush like element which confronts a needle dropping hole formed in a sole of the presser foot, a frictional contact between the needle and the brush like element is produced when the needle passes the outside of the fabric edge, without penetrating the fabric, to stitch a portion of hem stitches on the outside of the fabric edge. The brush like element may be secured to the sole of the presser foot, or alternatively to a fabric guide member for engaging and guiding the fabric edge. The brush may be projected in the fabric feeding direction or across the fabric feeding direction. A pin may be located just beneath the brush like element for constant placement thereof.

    摘要: A thread loop regulating arrangement is provided in a sewing machine having a reciprocated swingable needle carrying an upper thread and a loop taking arrangement including a rotatable loop taker, a bobbin carrier having a predetermined surface to receive thread loops and a bobbin positioned within the bobbin carrier. The thread loop regulating arrangement includes a relatively flat plate placed against the predetermined surface of the bobbin carrier and spaced therefrom and a downwardly extended lip for guiding the thread loop pulled off the bobbin carrier and thereby preventing the formation of undesirable stitches.
