H2 Precision Straightener

H2 family of straighteners have been designed for heavier gauges (.020" to .500") and normally slower speed applications (30 to 200 FPM). But its ability to remove coil set and cross bow in today's tough high-strength, low-allow materials has proven itself in some of the most demanding applications. The H2 family of straighteners are also available with Quick Change Roll Cassette System.

Applications Include:

High Strength Low Alloy or Advanced High Strength Steels (HSLA or AHSS) where typical flatteners can not achieve the level of flatness.


  • Easy quick removal of roll cassette for cleaning or changing work rolls.
  • Multiple cassettes with different work roll diameters can be inter-changed in the same basic machine.
  • Two-point belt drive connection system eliminates problems of U-joints and shortens installation time.
  • Hanging cassette design eliminates adjustment backlash and improves calibration reliability.
  • Precision ball and socket set to align top and bottom roll banks for accurate alignment.
  • Hardened and precision ground work rolls supported with double row needle bearings.
  • Continuous light oil lubrication with flow and level monitoring.
  • All electrical drives, controls and panels are machine mounted.
  • Proven performance and durability in the toughest stamping applications.


  • Speed control package provides stable accurate loop control when straightener is feeding material into a loop.
  • Motorized entry and exit adjustment incorporates pushbutton control entry and exit roll position with PLC controlled travel and tilt limits.
  • Entry edge guide provides material guidance on the entry side of the straightener.
  • Powered pinch roll aids in the threading of material into the straightener and extends the life of the work rolls.
  • End of strip sensor indicates the presence of strip and turns off the ready to run signal to the press when the strip is not present.
  • Powered pull roll adds tension to the strip to allow the machine to obtain flatter strip in thin-high strength materials.
  • Powered coil hold-down and peeler table.
  • Integrate reel and coil car controls straightener controls.
