Precise roll lengths and surface measurement of paper
Accurate length measurement of paper, tissue, packaging material regardless of grammage – also as a basis for square size accounting. Length measurement of the tambur, on the winder or longitudinal / cross cutter with high material speed. The contactless laser encoder system μSPEED serves as a gauge which is maintenance-free, almost independent of material and can be used with consistently high accuracy at high and low speeds.
Typical application data:
- Path Velocity: typically up to 3,600 m / min
- Measurement accuracy with tactile measuring equipment or via drive: typically 1 – 2%
- Measurement accuracy with non-contact length measurement μSPEED: typical: 0.03%
- Amortization: 1 month, direct encoder replacement, no other modifications needed
Material examples:
- Graphical paper, carbonless paper, thermal paper, filter paper, wallpaper, decorative paper, …
- Raw paper, coated paper, uncoated paper, machine smooth, satin, …
- Cardboard, Cardboard, Tissue Paper, Hygiene Paper, … all basis weights and grammages
Machines equipped with non-contact length measurement:
- Paper machine on tambour
- Roll Cutting Machine, Roll Cutter, cross cutter, lengthwise cutter
- Wrapping machines, rewinder, re-roller, doctor roller, cross-cutting sorter
- Coater, calender
