Map it on the Rewind.
Remove it on the Unwind.

RollTagger builds a digital map of every roll as it winds — recording defects, splices and quality events at precise positions. On the unwind, that map drives automated waste removal. No physical tags. No manual watching.

Key Features for Roll Tracking

Removes requirement for inserting tags or marking the edge of your product

Rewind & Unwind Modes

Rewind mode generates a map, measuring diameter and thickness. Unwind mode uses the rewind map to automate waste removal while unwinding.

Mapping Rolls

Real-time mapping with graphical display showing all key events such as defects and splices. Timestamp, linear offset, wind location and radial offset all latched.

Job Management

Intelligent queue system for roll ID and map input, output, and backlog management. FIFO ordering with optional MES/ERP integration.

Multi-Process Defect Tracking

Track defects through multiple processes and remove at final operation such as slitting, while maintaining roll lineage and calculating material waste at each stage.

Unwind Verification

Automated wind separation verification to identify positional anomalies such as material cuts or sagging. Compare actual vs expected positions with deviation alerts.

Machine Interfaces

Input/Output to interface with commercial vision systems, unwinder splice detection and automated turret rewinders. System can be configured to operate automatically with no operator input required.

Rewind Demo

Build a digital map while winding

  • Start a new roll and watch the map build in real time as the roll winds
  • Tag defects, splices, and quality checkpoints at any position
  • Live display of diameter, thickness, speed, and wind count from encoder data
  • Visual roll map grows with every wind — see events marked at exact positions
  • Queue management — create, identify, and transfer rolls to the output queue
  • Demonstrates how a complete roll map is generated ready for unwind processing
Launch Rewind Demo

Unwind Demo

Automate waste removal on the unwind

  • Load a roll map generated during rewind and play it back as the roll unwinds
  • Upcoming defect and splice alerts displayed ahead of position for operator readiness
  • Automated wind verification — compare actual vs expected position at every milestone
  • Position counts down to zero — deviation alerts warn of sagging or material cuts
  • Machine interface outputs signal the process to stop or adjust at tagged events
  • Demonstrates how waste is removed automatically using the rewind map
