Covering Machines for Spandex

Short Description:

Important Features

This covering machine is developed on the basis of well-proven designs and constructed in modular structure. The machine is able to fulfill the covering of Spandex by synthetic filaments or short staple yarns. Two main motors controlled by independent inverters are fitted at the machine end. One is to drive collectively all the spindles of the machine, another is to drive the winding motion of the whole machine take-up positions. This configuration makes the spindles of the complete machine run in a true uniform speed and helps the winding of all the take-up positions achieve a precise and even package formation. The machine is equipped with computerized electronic systems for feeding, drafting, twisting and winding, it guarantees the covering has both correct draft and twist ratio, and as a result gets a perfect package formation. All the production parameters, including the winding cross-angle, the take-up tapering, lip breaking, draft ratio and twist times, can be easily programmed in the touchscreen of the machine!
