Cortex Speeder Improves Weaving Warp Quality

France-based Cortex has developed the Speeder, a loom attachment designed to improve warp yarn characteristics and warp behavior to increase yield.The Speeder is suitable for yarn and loom applications subject to strong mechanical constraints and high demands for quality yarns, such as fabrics used in airbags, sails, luggage and filters.The attachment includes a one-piece heating beam that retracts automatically and is synchronized with the stop or go of the warp. It is suitable for treating thermoplastic yarns such as high-density polypropylene, polyester, nylon and even glass.Acting simultaneously in two complementary ways, the Speeder makes the warp temporarily elastic for better and easier weaving and improves the characteristics of the warp yarn.The Speeder reduces the elasticity modulus, enabling warp tension to be reduced by up to 50 percent. The reduced tension lowers friction and guide-rail abrasion, reduces the number of broken ends and blockages, and reduces batten noise, while increasing weaving speeds. The extra elasticity also allows different take-ups between yarns.
