1-needle, unison-feed, lockstitch machine with vertical-axis large hook and automatic thread trimmer (shorter-thread remaining type for sewing car seats)

This model of sewing machine is best-suited to car-seats manufacturing factories.
The machine achieves beautifully-finished seams with its shorter-thread remaining type thread trimming mechanism.

Product features

  • Responsiveness to materials has been substantially improved

    This single unit of 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 garment body.

  • Seam quality and sewing performance have been greatly improved

    • Well-tensed seams can be produced with a 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 which 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 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.
    • Frequency of use of scissors is also reduced, thereby contributing to the prevention of damage to the fabric by scissors.
