This Juki LU-1511N-7 one-needle machine with a thread trimmer utilizes a basic performance which matches best to the sewing of medium to heavy materials.

The Juki LU-1511N-7 machine’s rectangular feeding motion promises the consistent feeding of materials of all thicknesses without stitch gathering.

The basic machine and its outstanding response to the sewing of heavy materials.
JUKI’s unique feed mechanism promises excellent efficiency of feed. In addition to the standard models of Juki LU-1511N-7 1-needle and 2-needle machines, other models intended for special purposes are available, including models for extra heavy materials and one having a thread trimmer. The Juki LU-1511N-7 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 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 Juki LU-1511N-7 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.
