Description Vendor

The BST SLITTINGControl is a specialized slitting-control system engineered for high-precision, final-dimension cutting in fuel-cell and membrane electrode assembly (MEA) production lines. Its core function is to provide real-time tracking of daughter-roll width and coating-position measurements, continuously comparing these metrics against target values to spot knife-position or wear-related deviations. Equipped with automated closed-loop correction, the system can instantly command a FRAMEGuide web-guide to adjust the material's position right before the cut is made. This verified technical profile provides buyers with a precise engineering blueprint to evaluate when integrating smart automation and automated waste-reduction loops into high-speed fuel-cell manufacturing lines.

Use Cases

  • Final-dimension slitting of fuel-cell and MEA materials
  • Detection of incorrect knife setup or machine wear
  • Inline verification of coating position before cutting
  • Automated correction of material position ahead of the slitting process

Capabilities

  • Measures every daughter-roll width
  • Compares width and coating position with setpoints
  • Signals deviations requiring operator attention
  • Automatically corrects web position through FRAMEGuide
  • Provides live process data to connected production systems
BST GmbH BST GmbH, a wholly owned subsidiary of elexis AG, is a German leading full-service provider of quality assurance systems for web-processing industries, with dedicated inline quality assurance systems now applied to battery and hydrogen fuel cell electrode material manufacturing. The company's BST iPQ-SurfaceENERGY system provides high-end surface quality control during the production of fuel cell and electrolyzer electrode materials, while its SLITTINGControl and COATINGControl systems ensure precise coating position and web width alignment critical for scaling fuel cell mass production. BST has completed over 100,000 installations in more than 100 countries, formed through the 2014 merger of BST and eltromat, and presents masterclasses on inline quality assurance for fuel cell mass manufacturing at industry events like Hydrogen + Fuel Cells Europe. The company's core competencies span web guiding, register control, defect detection, and automation for the printing, packaging, film, battery, and hydrogen production sectors.
