An undetected break, crack or defect in a roll of paper, tissue or any continuous web product will cause major problems in downstream processes. It is necessary to mark so downstream operations can take proper corrective actions. The practice of hand marking is unreliable and unsafe. Ryeco’s Marking Systems offer a safe and reliable method to mark web breaks automatically.
The Ryeco Edge Marking System:
- Sprays up to 3 colors of defect marks on any web material at any speed.
- Marks can be continuous or pulsed for the length of the defect or as short as 0.5 milliseconds.
- Marks can be visible to the human eye or detected with a Mark Detection System.
- Marks can be invisible and only detectable with a Mark Detection System.
- Mark defects automatically from a Web Inspection System or with process control equipment.
- Operators can manually mark defects via the system’s control cabinet, as they occur.
The system places marks on a web at a position relative to a defect or process upset.
The system encodes values onto a moving web.
The system places a mark on the web after a sheet break is restored.
End of Roll Marking
The system places a mark on a roll to indicate that the end of the roll is approaching downstream operators and users.
The system places marks on a web at precise distance intervals to be used as a registration mark for downstream processes.
The system places continuous or dashed stripes on a web to indicate web orientation or product type.
Sheet Count Marking
The system counts sheets as they are stacked and places a mark at a specified number of sheets.
This system is used to track instantaneous stretch and shrinkage in a flexible web.
Length and Position Control
Identify your current position consistently.
Auto-Stop on Defects
Eliminate wasted time searching and improve quality.
End of Roll Auto-Stopping
Never run-off or leave good product on the core.
Track ALL waste or scrap down to the inch (25mm).
Control the precise length of all daughter rolls.
Stretch and Shrink Monitoring
Identify real-time distortion of flexible webs.
