Solutions
Web Guiding Edge, center, and line guiding solutions

Edge Guiding Align to the physical web edge. No calibration, no mechanical adjustments.

Line/Contrast Guiding Guide to a printed line or contrast boundary — no physical edge required.

Center Guiding Track web center automatically as width changes. No sensor repositioning.

Unwind Guiding Start every process from perfect alignment, regardless of roll quality.

Rewind/Winder Guiding Build tight, level rolls with dynamic edge tracking at winding speed.

Master/Slave Synchronize two guides electronically for perfect lamination and registration.

Chase/Follow Shift process stations to follow the web — ideal for slit-to-print alignment.
Sensing and Measurement Width measurement, thread counting and inspection

Edge Detection and Position Measurement Measure web edge position with ±0.0635 mm resolution on any material.

Web Width Measurement Measure web width from both edges simultaneously — no contact required.

Thread Counting Count individual threads or filaments using spatial filtering — no contact.

Splice Detection Detect web joins and splices automatically at full production speed.

Flag Detection Identify web flags and material anomalies for downstream process control.

Surface Defect Detection Detect surface anomalies and defects without stopping the production line.
Industries
Battery Manufacturing Precision electrode alignment for tighter cell yields and less scrap.

Converting & Felxible Packaging One sensor for every substrate — no recalibration between materials.

Film Extrusion Non-contact edge detection for continuous extrusion lines.
Flexible Printed Electronics Sub-millimeter registration at full production speed for roll-to-roll FPE.

Label & Narrow Web Precise guiding in tight spaces — works on clear film and bare liner.

Metal Processing Handles camber, reflection, and heavy loads up to 30,000 lbs.
Nonwovens & Hygiene Reliable sensing on porous, low-contrast webs that fool other sensors.

Paper & Printing Immune to paper dust and flutter at high press speeds.

Pharma & Medical Clean, data-rich guiding for validated medical packaging lines.
Textile & Composites From carbon fiber tows to high-speed looms — sensing for advanced materials.

Tire & Rubber High-contrast sensing for black, absorptive materials on heavy tire lines.
