LU-1520NCS-7

1-Needle, Unison-Feed, Lockstitch Machine with Vertical-Axis Large Hook. Includes Shorter-Thread Remaining Type Thread Trimmer.

This model of the sewing machine is a straight knife with a shorter-thread remaining type thread trimmer, compound feed machine. It is based on the tried-and-trusted LU-1510NA-7 Series and achieves the best-suited seam quality for sewing car seats. In addition, the thread nipping process which has been conventionally required at the end of sewing is no longer required, thereby eliminating concern about damages on sewn products by scissors.

Responsiveness to materials has been substantially improved.

This walking foot machine is able to smoothly sew a wide variety of materials such as genuine leather, J-clip (plastic), heavy-weight materials for men's trousers, light-weight fabric materials, and even light-weight materials which need to be sewn with stretched to remove the slack in the garment body.

Seam quality and sewing performance have been greatly improved.

- Well-tensed seams can be produced with lower thread tension. (Needle thread tension can be reduced by 50% in comparison with that required for the conventional models.) 
- Even when sewing a light-weight material that needs to be sewn with stretched, the machine is able to reduce puckering. 
- The machine is able to reduce the frequency of occurrence of thread breakage, stitch skipping, needle breakage, and isolated idling loops. 
- Since the machine produces well-tensed seams even when using a thin higher-count needle, it is able to provide finished seams that ideally match the material.

Needle thread clamping device.

This device pulls the needle thread into the wrong side of the material at the beginning of sewing, thereby ensuring more beautifully-finished seams.

The length of thread remaining on the material after thread trimming has been reduced to save manual nipping by the operator.

- The machine has adopted a newly-designed direct-drive thread trimming mechanism to shorten the length of thread remaining on the material after thread trimming.
- This results in the reduction of manual thread nipping at the end of sewing.
- The frequency of use of scissors is also reduced, thereby contributing to the prevention of damage to the fabric by scissors.
