ROBUST – Foil cutting machine with part length measurement

foil format cutting machines and winding technology

ROBUST is specialized in slitting machines and winding technology. The product range includes roll slitting and winding machines, lengthwise slitting and cross cutting machines as well as machines for laminating, coating and gluing. In ROBUST cutting machines, ELOVIS length measuring systems ensure that the length accuracy is maintained and that the measurement results are 100% documented. In the application described here, the SLM discrete part length measuring system measures transparent, optical foil format sheets for displays and monitors with high precision over length.

Typical application data:

  • Measurement of foil formats after cutting, before sorting / packaging
  • Production speeds: typically up to 1 pcs/sec or 20m/min
  • Cutting system without SLM system: only random sample inspection possible, accuracy: +/- 0.5mm/m
  • 100% measurement with non-contact length measurement SLM, typical accuracy: 0.2mm/m
  • Amortization: 2 months, integration of the measuring system into Weerth Anlagentechnik

Material examples:

  • Foil formats, foil plates
  • Foil thickness: from 100 µm to 500 µm
  • Foil size: up to 1200 mm x 2050 mm
  • Foil-Material: PE, PUR, PVC, …

ROBUST machines, which are extended by non-contact length measurement:

  • Longitudinal and cross / format cutting machines
  • Roll cutting and winding machines
  • Cutting machines for the photo voltaic industry
  • Cutting machines for the timber and furniture industry
  • Winding and rewinding systems
  • Core cutting machines
  • Coating and laminating systems
