1-needle, Unison-feed, Lockstitch Machine with Vertical-axis Large Hook and Automatic Thread Trimmer

The machine demonstrates sewing capabilities best suited for sewing car seats of light- to heavy-weight materials without using any additional devices.

Product features

  • Comparison of needle-thread tension

    The LU-1510NA-7 is able to consistently sew adequately-tensed stitches with a needle-thread tension that is "25%" lower than that of the conventional models. With this feature, the machine is adaptable to light-weight materials and is capable of reducing puckering.

  • Responsiveness to a broader range of materials

    Taking an extreme example, in a process where different types of materials are used or where materials that differ in thickness are used, the machine is able to sew the materials in one shot without adjusting the needle thread tension. The machine, therefore, reduces the load applied to the materials and produces uniformly-tensed stitches with consistency.

  • Adaptable range of sewing
