Straightener

Straightener Machine (coil levelers) are engineered to deliver consistent flatness and dimensional accuracy for sheet material processing. Straightener Machine are Designed to work with decoilers and feeders, our straighteners remove coil set and waviness, ensuring reliable feed and improved part quality.

Key Features of Straightener Machine

  • High-precision roller sets with hardened surfaces for extended life.
  • Adjustable roller geometry for different material thicknesses and widths.
  • Rigid heavy-duty frame to minimize vibration and maintain accuracy.
  • Quick setup and easy mechanical adjustments for fast changeovers.
  • Compatible with steel, stainless steel, aluminum and copper coils.
  • Optional motorized models and manual economical variants available.
  • Designed for seamless integration into coil-to-press feed lines.

Technical Advantages of Straightener Machine

Our straighteners use precision ground rolls, quality bearings and robust adjustment mechanisms to achieve repeatable flatness. The machines reduce material scrap, improve stamping yield and prolong tool life by delivering uniform sheet entry to feeders and presses.
