Converting Solutions
Monarch Paper Group’s marking technologies for converting processes help eliminate off-spec material before it reaches your customers. Our system applies a colored or invisible mark on the web at the point of a process upset, either manually by an operator or automatically through integration with web inspection or process control equipment. We offer specialty-formulated dyes for a range of materials, from food-safe options to solvent-based solutions, ensuring reliable marking for your specific needs.
How Converting Defect Marking Works
Marking defects on a web and subsequently removing them ensures your customers receive the quality product they expect. Monarch’s product line gives machine operators the quality control tools to achieve that efficiently and accurately — marking the defect at the moment it occurs, so the off-spec section is identified and removed rather than shipped.
Lane and Edge Marking Configurations
Two configurations cover converting geometry. Lane marking can mark down a single lane, across multiple lanes of the web, or inset from the web edge where space is limited. Edge marking is used on the edge of the web and includes an overspray evacuation system to keep the surrounding area and the machine clean.
Automatic Marking via Web Inspection Integration
The marking system can be triggered automatically through integration with a web inspection system or process control equipment. This is the same defect-marking platform used on the paper machine, applied to the converting line — and it interfaces with any web inspection system, not only one vendor’s.
Manual Marking for Operator-Controlled Identification
Some converting operations prefer operator control. The system supports manual triggering so a machine operator can mark a defect or process upset as they see it — without hang-flagging, which is the practice this replaces.
Applications Across Converting
Monarch converting defect marking is in service across:
- Paper and paper converting
- Tissue
- Films, foils and plastics
- Nonwovens
- Labels and narrow webs
- Packaging
- Lamination and coating
- Batteries
Specialty-Formulated Dyes for Every Converting Material
Converting lines run materials that behave very differently under a marking head. Monarch supplies specialty-formulated dyes matched to the substrate, so the mark is visible where it needs to be and compatible with the product’s end use.
Benefits
- 100% defect-free product delivered to the customer
- Data to eliminate the source of defects, not just flag them
- Reduced downtime from process upsets
- A safer work environment by eliminating the dangerous practice of hang-flagging and hand-marking
Frequently Asked Questions
What converting processes does Monarch’s marking system support?
Monarch’s converting defect marking systems work across paper and paper converting, tissue, films, foils and plastics, nonwovens, labels and narrow webs, packaging, lamination and coating, and battery production. The system can be triggered manually by an operator or automatically via web inspection or process control.
What materials can the marking dyes be applied to?
Monarch offers specialty-formulated dyes for a range of materials, from food-safe options for food-grade converting to solvent-based solutions for industrial applications.
What is the difference between lane marking and edge marking?
Lane marking places marks down one lane or across multiple lanes of the web, or inset from the edge where space is limited. Edge marking places the mark on the web edge and includes an overspray evacuation system.
Does this replace hand-flagging?
Yes, and that is a large part of the point. Hang-flagging and hand-marking on a running converting line is a safety exposure. Automatic marking removes the need to reach into the machine.
