The RT-B8901 spring soft mattress overlock sewing machine, which was listed as the first batch of municipal new product development plans in 1990 in Ningbo City, was trial-produced by Ningbo Spring Machinery Factory. The Ningbo Jiangbei District Committee was entrusted by the Ningbo Science and Technology Commission. From October 30 to October 31, 1990, various experts were organized to conduct technical appraisal of the equipment and passed it. The successful trial production of the spring-soft mattress overlock sewing machine is a product of self-reliance and digestion and absorption of imported equipment. It has made positive contributions to improving the domestic matching capacity and realizing the localization of the Simmons production line.
