Tension Leveller

Function: it straightens, bends and levels galvanized plates/sheets under certain tension i.e. percentage elongation for bettering plate shape, raising straightness and eliminating part of yield platform.

Structure: composed of 2-bending-1-straitening leveler, include 2 bending units and 1 straitening units. The lower rollers bases of bending units and straightening units are driven by hydraulic cylinder to quickly open, and are fine adjusted by motor through worm lifter. Two upper straightening rollers are fine adjusted by motor through worm lifter or by hand.
