LU-1508N, LU-1509N Series
1-needle, Unison-feed, Lockstitch Machine with Vertical-axis Large Hook
Product features
JUKI's unique feed mechanism promises excellent efficiency of feed. In addition to the standard models of 1-needle machine, other models intended for special purposes are available, including models for extra heavy materials and 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 general use, such as car seats, sofas and bags, thereby contributing to both improved quality and increased productivity.
A new feed mechanism with a rectangular feeding motion prevents stitch gathering
The alternating vertical movement mechanism prevents irregular stitches
Consistent seam quality
Higher lift of the presser foot
The high, 16mm foot lift enables easy material handling.
The machine comes with a dual-tension mechanism
The 1-needle type machine has adopted a dual-tension mechanism, with which the machine can support high-tension sewing with thick thread. This means that the machine produces seams of excellent quality on a broader range of materials, extending from light- to heavy-weight.
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.

Basic performance
Improved operability
The area around the needle entry is designed to be easily observed (LU-1510N-7, LU-1511N-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-1510N-7, LU-1511N-7)
Thread trimming without fail (LU-1510N-7, LU-1511N-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-1510N-7, LU-1511N-7)
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.
