Suitable for twisting various BCF yarns (PA, PP, PES, PTT, etc.), synthetic filament yarns (PA, PP, PES, PTT, etc.), and staple fiber yarns, etc. Main functions of the machine 1. It adopts electric spindle structure and adopts digital frequency converter to adjust the spindle speed. The maximum mechanical spindle speed can reach 9000rpm; it is easy to clean and maintain; it can complete the conversion between two-for-one twisting and direct twisting through simple parts conversion. 2. The winding motor, overfeeding motor and traverse motor are all driven by their own frequency converters and controlled by PLC
