1-needle, Unison-feed, Lockstitch Machine with Vertical-axis Large Hook

JUKI's unique feed mechanism promises excellent efficiency of feed. In addition to the standard models of 2-needle machines, other models intended for special purposes are available, one having a thread trimmer. The machine is applicable to an extended range of heavy materials for industrial use, such as cargo handling belts and containers, as well as those for industrial use, such as cargo handling belts and containers, as well as those for general use, such as car seats, sofas and bags, thereby contributing to both improved quality and increased productivity.

Product features

  • A new feed mechanism with a rectangular feeding motion prevents stitch gathering

    • The new mechanism with a rectangular feeding motion promises consistent feed of materials of all thickness without stitch gathering.
    • The lower orbit of the feed dog prevents the material from flopping and reduces operating noise and vibration.

  • The alternating vertical movement mechanism prevents irregular stitches

    • The machine has adopted a new mechanism that does not change the ratio of alternate vertical movement of the walking foot and presser foot even when the material thickness changes.
    • Even when a heavy-weight material is used, the presser foot lift does not decrease. This means that the presser foot comes into contact with the material at exactly the same time that it does when sewing lighter-weight sections of the material. As a result, the walking foot retains the material with a consistent pressure to prevent irregular stitches.
    • The amount of the alternating vertical movement of the walking foot and presser foot can be adjusted up to the maximum of 6.5mm according to the height of multilayered portions of material.

  • Consistent seam quality

    • With the adoption of a new rectangular feed mechanism, an alternating vertical movement mechanism, and a unison feed mechanism, the machine can feed heavy materials powerfully and smoothly. Well tensed seams are consistently produced without pitch errors.
    • With its maximum stitch length of 9mm, the machine can be applied to a broader range of uses.

  • Higher lift of the presser foot

    The high, 16mm (13mm for LU-1565N) presser foot lift enables easy material handling.

  • The highly efficient vertical-axis double-capacity hook is equipped as standard

    With the adoption of this vertical-axis double-capacity hook, the frequency of bobbin thread changing is reduced, promising sewing work of increased efficiency.

  • LU-1560N, LU-1561N
    (with automatic lubricating mechanism)

    • The standard 2-needle type machine that delivers the basic functions and performance best suited to the sewing of heavy materials.
    • Automatic lubricating mechanism improves maintainability. The sub oil pan and double filter prevent dust from entering the oil.

Basic performance

  • Improved operability

    • The stitch length can be easily selected by the stitch dial.
    • The machine is provided with many improved features that offer enhanced operability such as an easy-to-observe area around the needle, placement of the bobbin winder on the front face of the machine arm, and a large handwheel (φ160).
    • A knee-lifter mechanism is built in the bed. This reduces the pressure required to operate the knee-lifter and facilitates setup. (Machines equipped with automatic thread trimmer are excluded.)
    • The machine is full-open-type top design makes it possible to fully open the top of the machine arm. Thanks to this design, adjusting works can be done without tilting the machine head.
    • The machine is equipped as standard with a safety clutch for preventing hook breakage. Reset work can be done simply by pressing a button.

  • The area around the needle entry is designed to be easily observed
    (LU-1560N-7, LU-1561N-7)

    Since the needle thread tension-release solenoid is fitted on the rear face of the machine head, the area around the needle entry and one-touch type reverse feed button is easily viewable. This substantially contributes to improved operability.

  • The walking foot and presser foot's alternating vertical movement can be set and changed with ease
    (LU-1560N-7, LU-1561N-7)

    • The vertical strokes of the presser foot and walking foot (their alternating vertical movement) can be easily changed using a large dial mounted on the top surface of the machine head.
    • In addition the sewing speed is automatically adjusted with the set value. With this feature, ideal sewing conditions are maintained at all times.
    • The machine is equipped with an instantaneous changeover device for alternating the vertical movement amount of the walking foot and presser foot, which demonstrates its capability for processes involving sewing products with a lot of multi-layered portions.

  • Thread trimming without fail
    (LU-1560N-7, LU-1561N-7)

    The machine leaves a shorter needle thread after thread trimming, improving thread consumption efficiency. With a rigid knife and improved cam shape, the thread trimmer cuts thread as thick as #5 without fail.

  • A helpful automatic reverse feed function is provided as standard
    (LU-1560N-7, LU-1561N-7)

    • With just a light press on the one-touch type reverse feed button, reverse feed stitching is actuated. Furthermore if a suspended ruler is attached on the machine or a 3-dimensional sewing product is sewn, the button can be shifted upward to prevent interruption.
    • The auto-lifter (pedal switch type) helps to increase efficiency by reducing operator fatigue.

  • Bottom-feed micro-adjustment mechanism is provided as standard
    (LU-1510N-7, LU-1511N-7)

    The 1-needle type machine is equipped with a bottom-feed micro-adjustment mechanism with the needle feed amount fixed. This helps prevent irregular stitches which are free from pitch errors.
