1-needle, Top and Bottom-feed, Lockstitch Machine with Double-capacity Hook

With its powerful top and bottom feed mechanism, the machine smoothly feeds a difficult-to-feed material or a multi-layered part of material without pitch errors, achieving consistent seam quality.

Product features

  • Higher lift of the presser foot

    The lift of the presser foot, by the knee lifter, is as high as 15 mm so as to support processes which require a higher lift of the presser foot, such as piping and tape-attaching.

  • The maximum stitch length is 9 mm

    With its stitch length being as large as 9 mm, the machine is applicable to a broader range of sewing processes.

  • The double-capacity hook is provided as standard

    The machine comes with a horizontal-axis double-capacity hook, not only to decrease the frequency of bobbin thread changing, but also to enable sewing work with increased efficiency.

Basic performance

  • Automatic lubricating mechanism

    A pump-unit type automatic lubricating mechanism dramatically improves maintainability. The oil amount in the face plate and hook is adjustable.

    The top feed mechanism employs a grease tank and oil wick lubrication mechanism.

  • The machine achieves low-vibration and low-noise

    The machine head is designed to achieve optimum balance, thereby reducing vibration and noise. The machine affords the operator a comfortable working environment.

  • Excellent operability

    • The stitch pitch can be adjusted in both the normal and reverse directions.
    • The height and inclination of the feed dog can be adjusted.
    • The amount of the alternating vertical movement of the walking foot and presser foot is adjustable in a range from 2 to 5mm according to the height of a multi-layered section of material.
    • The horizontal feed cam, top and bottom feed cam and top feed cam can be adjusted after openning the rubber caps (three caps) on top of the machine head.
