Bird's nest prevention device for LK-1900 (Computer-controlled bartacking sewing system)

This is a retrofittable optional kit to prevent the "bird's nest" at the start of sewing.

This device prevents the "bird's nest" that occurs on a bartacking sewing machine at the start of sewing. It automatically clamps the needle thread at the start of sewing and cuts excess thread with the built-in heat cutter to achieve the optimum needle thread amount. Beautiful stitches are realized by the quality improvement at the start of sewing and the effect of bird's nest prevention.
