Two-for-one twister

The invention relates to a double twister, comprising rack, twisting part, winding and forming part. The twisting part comprises a first driving wheel and a second driving wheel. The central line of the second driving wheel is parallel with the central line of the first driving wheel and nylon belt is tightened between the first and second driving wheels. There are multiple twisting spindles on the nylon belt. Said first driving wheel is connected with the rotor of a first motor and said second driving wheel is connected with the rotor of a second motor. In the invention as the second driving wheel is added the wear to nylon belt is lessened effectively and the service life is prolonged; meanwhile, the problem of uneven twisting degree of yarn is solved. It is more important to save 40% of electricity consumption, which has an important significance for developing and popularizing the new environmental protection equipment.
