Length Measurement of transparent Foil and Film

Abrasion-free, non-contact measurement of sensitive surfaces

Precise length measurement on transparent film and foil for the food indutry and optical films. Length measurement on particularly smooth and almost featureless surfaces. Non-contact and maintenance-free as well as permanently accurate measurement by ELOVIS μSPEED laser encoder systems.

Typical application data:

  • Path Velocity: typically up to 1,000 m / min
  • Measurement accuracy with tactile measuring equipment or via drive: typically 0.5-1%
  • Measurement accuracy with non-contact length measurement μSPEED: typical: 0.03%
  • Amortization: 3 months, direct encoder replacement, no other modifications needed

Material examples:

  • transparent foil and film, high-gloss film, food film, packaging film, furniture film and foil, …
  • PET film, PE film, PP film, PVC film, PS film, PLA film, …

Foil machines which are equipped with non-contact length gauges:

  • Roll Cutting Machines, Roll Cutter, Cross Cutter, Lengthwise Cutter
  • Winding machines, rewinder, re-roller, doctor roller
  • extruders, film casting machines, calenders
  • laminating machines, goods foam machines
