Latest Patents

**Method and Apparatus for Cutting Cover Thread in a Multi-Needle Sewing.** This invention describes a thread cutter whose hook retracts at an oblique angle above a curved cover-thread laying finger to capture the thread. The mechanism draws the thread to the cutting position while holding it against a specified needle, then retains the thread end after cutting.

**Taped Chaining Thread Sewing Device.** This device uses an overedge sewing machine to sew tape onto the upper surface of fabric and chaining thread onto its lower surface. A cutter trims the tape along with excess fabric at the start of sewing and removes the unsewn tape near the end. The chaining thread sewn into the beginning of the fabric can eliminate the need for a separate bar-tacking operation. Adjusting the timing of the thread-processing device also allows the sewn-in chaining thread to be set to a specified length.

Career Highlights

Ichimura’s listed inventions address practical sewing-machine operations, including thread capture and cutting, tape handling, and the integration of chaining thread into fabric. These mechanisms are designed to coordinate sewing and trimming steps within the production process.

Collaborations

Ichimura’s listed coworkers include Koichi Okada and Yoshikazu Kageyama. His work is associated with Pegasus Sewing Machine Mfg. Co., Ltd.

Conclusion

Takashi Ichimura’s patents focus on improving thread and tape handling in industrial sewing, combining cutting and sewing operations to support efficient fabric processing.
