2:resistant to waer

expand roll

 

Widely used in the size press,calender, winder and slitter machines' paper spread, with unique structure.

 

The curvature of the roll can be adjusted in a certain range, so to satisfy the high speed machine, special paper and multi-kind paper's requirements.

 

Breach the malpractice of the fixed curvature of the conventional rollers.

 

Coverter motor work on the end of the roller's shaft ,completely solve the paper and roller's speed matching problem.

 

Manual hydraulic motor adjusts the curvature, then accurate locate mechanically to ensure the precise curvature.
