Furthermore, there is a method of increasing the shift from the cylinder to the doffer and reducing the working angle of the doffer for the purpose of high production.However, in this case, the tooth strength of the wire is weak, so the damage of the doffer wire is quick,
There is a problem that the life is shortened.

If it exceeds 85 °, the spreadability decreases. Also, the tooth depth B is
If it is less than 0.5 mm, the fiber-opening effect is reduced, and the production amount is reduced. If it is more than 2.0 mm, the fiber is wound around the cylinder wire. The working angle X of the metallic wire for the doffer is suitably 45 ° to 70 °, and if it is less than 45 °, the tooth strength decreases, and if it exceeds 70 °, the transfer rate from the cylinder to the doffer decreases and the sliver quality decreases.
