In the official world record challenge initiated by Bruce Sewing Equipment Co., Ltd. in Guangzhou, China, the Bruce BOMBER 5000 overlock sewing machine, a standard model, was used to continuously sew at a speed of 6000 RPM. For this challenge, a bone section was placed every 30 centimeters on fabric, each section at least 6 millimeters thick. Throughout the process, there were no occurrences of skipped stitches, thread breakage, or misalignment. The final effective length achieved was 1,001 meters. Verified by the WRCA, the event has successfully set the world record for the “The Overlock Sewing Machine with the Longest Continuous Sewing Without Skipping Stitches or Thread Breakage”.
