There are also two roller straightening machine, relying on two rollers (Concave Intermediate, hyperbolic roll) the perspective of the different changes in the diameter of the material straightening.
也有两辊矫直机，依靠两辊(中间内凹，双曲线辊)的角度变化对不同直径的材料进行矫直。
The device can be compressed into a roll material wire diameter, and increased the density of the material, length.
本设备能将材质一次压缩成滚丝直径，且增强了材质的密度，长度。
