Multi-Blanking-Lines

Multi-Blanking is a process in which multiple blanks of different or equal widths with the same lengths are produced from a flat rolled master coil.

Efficient multi-blanking lines for precise coil processing

In this process, the coil is first cut into longitudinal strips, which can be equal or of different widths. Then, they are transversally cut into blanks and moved to the final stage to be stacked into bundles.

Depending on the requirements and productivity, our multi-blanking lines are equipped with fixed shears (start-stop), flying, rotating, or double eccentric shears for continuous line operations and accessorized with its matching stacking system for optimal output.

Depending on the required flatness precision and surface quality, these are exclusively equipped with our in-house SCHNUTZ precision leveling machines. In addition, we can integrate various measuring systems, side trimming, paper applicator devices, and scrap/reject disposal systems.

Advantages of a b+s Multi-Blanking-Line

  • strip flatness is ensured by the integration of a high-performance leveler from the world market leader SCHNUTZ
  • eliminating strip imperfections by using a “4-high”, “5-high” or “6-high” leveler
  • reduction of set-up times through innovative automation solutions as well as high line speeds
  • high-precision cut quality and angularity of the blanks
  • strip cutting with integrated edge trimming shear and scrap disposal systems, such as scrap winder or scrap cutter
  • high precision stacking accuracy as well as no surface damage due to advanced stacking systems
  • experience in processing ultra-high strength materials with tensile strength over 1,500 N/mm² (0.22 pound/square inch) and a yield strength over 1,100 N/mm² (0.16 pound/square inch)
