Efficient & powerful

Maximize your output – with a high number of cycles, short set-up times, and stable performance

  • High-speed cutting:
    Up to 180 cuts/min (single track) or 360/min (double) – with constant cutting quality and a maximum belt speed of 6.5 m/s.
  • Tool-free conversion—ready in minutes:
    Quick-release system, tool-free changeover and maintenance-free components reduce set-up time by up to 80%—for maximum flexibility and availability.

Precision & Quality

Ensure the highest quality. Measure, control and monitor automatically – in real time.

  • Cutting without length fluctuations:
    The flying guillotine guarantees consistently precise cutting lengths.
  • Quality 100% inline tested:
    Inline height, density and Louver Angle Measurement System – maximum control for every part.
  • Precise to the last detail:
    ± 0.05 mm belt guide at 6.5 m/s – fully automatically controlled.

  • Constant slat height:
    Belt force control keeps heights constant – even under changing conditions.

  • Automated belt guidance:
    ± 5° belt path correction for perfect cutting quality.
