High-speed, Unison-feed, Lockstitch Machine with Vertical-axis Large Hook and Automatic Thread Trimmer

Capabilities for sewing car seats have been significantly improved.

Product features

  • Capabilities for sewing car seats have been significantly improved

    Efficiency of feed and sewing capabilities for supporting sewing performance at a higher speed of 3,500sti/min

  • LU-2212N-7 
    (1.6 fold-capacity hook / 2-pitch dial type)

    One of two different stitch lengths can be selected according to the application.
    The stitch length can be instantaneously changed over by pressing the stitch selector switch mounted on the lower part of the machine arm.

  • LU-2220N-7 
    (1.6 fold-capacity hook / 2-pitch dial / Shorter thread remaining type)

    Thread nipping work required at the beginning and end of sewing is reduced. This is a high-performance machine which contributes to both increased productivity and improved quality for sewing car seats. Frequency of the use of scissors by the operator is reduced, thereby helping prevent the material from being damaged.

Basic performance

  • Higher lift of the presser foot

    • The machine is provided as standard with a pneumatic auto-lifter.
    • The high, 16mm presser foot lift enables easy material handling.

  • The walking foot and presser foot's alternating vertical movement can be set and changed with ease

    • The vertical strokes of the presser foot and walking foot (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 vwith the set value. With this feature, ideal sewing conditions are maintained at all times.

  • The highly efficient vertical-axis 1.6 fold-capacity hook is provided as standard

    With the adoption of this verertical-axis 1.6 fold-capacity hook, the frequency of bobbin thread winding is reduced, promising sewing work of increased efficiency.

  • Instantaneous change-over device for the alternate vertical movement amount (DL device) is provided as standard

    • The alternate vertical movement amount can be instantaneously maximized in a process for sewing a hard-to-feed part of material, such as a multilayered part, finishing with beautiful seams free from stitch gathering.
    • The machine is provided with both a hand switch and knee switch.
