Draw frame

The working principle of the draw frame mainly involves the drafting of cotton fibers through a series of rollers and aprons, which further separates the fibers to achieve merging and evenness.

The function of the drawing machine in spinning process is to improve the internal structure of the sliver, enhance its long segment uniformity, and reduce the weight unevenness rate.

Our digital drawing machine, based on traditional drawing machines, incorporates digital technology and advanced control systems to achieve higher production efficiency and better product quality. In the process of spinning, different spinning varieties, such as open end rotor spinning or ring spinning, use drawing frames with different first roller diameters.

Advantage of draw frame

  • Imported Uster evenness system.
  • The cleaning roller is made of velvet, which may need to be replaced once a year.
  • All rollers have the same diameter, making it more suitable.
