LU-1520N-7(Gauge for standard), LU-1521N-7(Gauge for LU-2200)

1-needle, Unison-feed, Lockstitch Machine with Vertical-axis Large Hook and Automatic Thread Trimmer (needle thread roll-in and short tail remaining type)

Thread picking is no longer required at the beginning and end of sewing. This is a high-performance machine that is ideally suited to the sewing of car seats.

Thread picking work that has traditionally been required by conventional machines can now be virtually eliminated, thereby drastically increasing productivity.
In addition, jut-out thread problems or accidents in which the material is damaged by scissors during sewing can be prevented.
The machine contributes to reduced cost and upgraded quality in the sewing of car seats.


LU-1520N-7-OBBAA / XC-E500    


Thread picking is no longer required at the beginning and end of sewing.
The remaining length of thread at the end of sewing is substantially shortened to approximately 5mm.
The machine cuts thread as thick as #5 without fail.
Even if the needle thread is clamped under the presser foot or walking foot, the machine draws the needle thread onto the underside of the material without fail, leaving no exposed thread on the right side. The needle thread drawn onto the underside of the material can be sewn under the seam.
The end-of-sewing thread is kept in the seam allowance both at the beginning and end of sewing and does not jut out from the material edge.
This function eliminates the need for thread picking. The operator is able to concentrate on sewing work without having to perform thread picking work, thereby dramatically increasing productivity.
The frequency of scissor use by the operator is significantly reduced, thereby preventing accidents in which the scissors damage the material.

Consistent seam quality.
The newly developed mode of highly rigid rectangular feed guarantees outstanding feed performance. In addition, the ratio between the alternating vertical movements of the walking foot and presser foot remains unchanged even when the material thickness changes. With this feature, the machine sews multi-layered parts of the material consistently and without stitch gathering.
The vertical stroke of the presser foot and walking foot (amount of alternating vertical movement) can be easily changed with the large dial mounted on the top of the machine head. The sewing speed is automatically regulated based on the vertical stroke setting.
This ensures ideal sewing conditions at all times.
The machine is equipped as standard with a mechanism to correct uneven material feed by making-micro adjustments to the bottom-feed.
  Compared with the elliptical feed, the rectangular feed helps reduce gathered stitches.
  The ratio of alternate vertical movement remains unchanged even when the material thickness changes.

Excellent operability and maintainability.
The stitch length can be easily selected with the stitch dial. The machine's enhanced operability features include placement of the bobbin thread winder on the front face of the machine arm, a large handwheel (160mm) and an easy-to-use reverse stitch lever.
A walking foot mechanism is built into the machine arm to prevent oil from scattering.

AC servomotor / controller SC-380
  The SC-380 is provided with many different standard functions, including speed-control, soft-start, automatic reverse stitching with the specified number of stitches, constant-dimension stitching, and overlapped (multi-layered) stitching.
These functions ensure sewing performance optimally suited to the material and process.
Control panel that improves functions of the sewing machine (optional)
  The XC-E500 is provided with program sewing and a host of other functions that contribute to increased efficiency.
