Latest Patents

Kurashima's latest patents include a sewing machine that can control tension on both the needle thread and the bobbin thread on a per-stitch basis. This technology enables even heads of a multi-head embroidery sewing machine to form identical embroidery. Additionally, it allows multiple sewing machines to produce the same embroidery design. The sewing machine features a memory device that stores embroidery data, including needle thread control torque values and bobbin thread control torque values. In the needle thread torque control zone, the upstream grip section main body is closed while the downstream grip section main body is opened, allowing for precise torque control. In the position control zone, the upstream grip section body is opened, and the downstream grip section body is closed, facilitating accurate position control.

Another patent focuses on a needle thread tension controller that can adjust the tension on a needle thread for each stitch. This innovation minimizes the chances of thread breakage and allows for easy detection of any breaks that do occur. The design includes an upstream grip section and a downstream grip section for gripping the needle thread, along with a turning section for managing the thread. In the torque control zone, rotating force is applied to a turning arm based on a specified torque value.
