Choosing between in-line and off-line converting for nonwovens and technical textiles

Since the 1970s, CAMPEN Machinery A/S has supported nonwoven and technical textile producers in choosing between in-line and off-line converting. Our solutions are reliable, robust and easy to operate. Whether you require in-line converting to maximise efficiency or off-line converting for greater flexibility, we help you select the right setup for your product range, material characteristics and production needs. Our engineers design systems configured for your process. We prioritise uptime, quality and operator safety, and we offer long-term service and technical support.

Key considerations for selecting in-line or off-line converting

The decision process for choosing between in-line and off-line converting starts with your product portfolio and changeover frequency. In-line converting is ideal when processing consistent product grades, running steady line speeds and handling predictable roll sizes. It can eliminate intermediate handling and help reduce production waste. Off-line converting is better suited to operations with frequent order changes, a varied product mix or fabrics requiring gentle handling. Decoupling production from finishing enables you to balance capacity, optimise shift planning and manage orders efficiently.

• Material behaviour: Certain nonwovens and technical textiles require low-tension or careful web handling to avoid defects.
• Target formats and volumes: Larger and uniform production runs are best served by in-line; diverse roll dimensions fit off-line converting.
• Downstream finishing: Inspection, slitting accuracy and packing capabilities need to meet specific client or market requirements.
• Tension regulation and web guiding: Consistent tension and web positioning affect finished roll quality and overall process stability.
• Production area and team skills: Evaluate available factory floor space and operator expertise before selecting a solution.
• Traceability and process data: Off-line lines often offer detailed inspection possibilities and improved documentation for quality control.

CAMPEN assists you in mapping these requirements, simulating orders and conducting trials with your fabrics. We give you clear recommendations and outline the impact on quality, cost, safety and workforce needs.

• In-line converting helps minimise handling steps, saves time and reduces work-in-progress inventory.
• Off-line converting offers flexibility, speeds up order changes and helps keep your main line running.
• Inspection and documentation are enhanced with dedicated off-line stations.
• Integrated roll change in-line supports complete line speed and minimises production downtime.

Integrated in-line converting systems for consistent production

Our in-line converting systems are designed for stable, continuous operation in high-output nonwoven and technical textile production. We integrate unwinders, winders, slitters and rewinders directly with your main line process. Advanced components—such as turret winders, automatic roll change and splice solutions—maintain process flow and maximise uptime.

• Advanced tension control protects sensitive webs and ensures uniform roll hardness for downstream processes.
• Precise web guiding improves slit edge quality, reducing waste and rework.
• Automatic roll change and minimal manual intervention help shorten changeover times and reduce operator workload.
• Integrated inspection and marking functions boost traceability and support claim reductions.
• Recipe control and synchronisation keep output quality consistent at any line speed.

We customise our equipment to match your fabric types, line widths and roll dimensions. Operator safety remains a top priority with CE-compliant safety solutions and ergonomic features. Remote diagnostics and process data logging enhance your ability to maintain high quality and uptime.

Off-line converting solutions for production flexibility

Off-line converting provides maximum flexibility in nonwoven processing. CAMPEN’s slitting and rewinding machines, unwinders and inspection units are robust and easy to operate. They help you handle a diverse order book, qualify new textile types and ensure your main production line is not interrupted by frequent changeovers.

• Configurable setups/process lines enable you to handle a variety of roll sizes and frequent format changes.
• Inspection stations help catch defects before finished rolls are packed, protecting your reputation and meeting customer expectations.
• Low-tension processing design is ideal for delicate or elastic materials to prevent stretching or damage.
• Fast knife adjustments and stored settings speed up changeovers and minimise waste.
• Efficient roll handling and integrated packing reduce lead times and labour costs.

We align off-line equipment capacity with your mainline production to avoid bottlenecks. Optional modules include edge trim extraction, dust control, static discharge systems and safe splice tables. For product development or quality approval, off-line converting allows tests and trials without affecting ongoing production.

Expertise you can count on

With decades of practical experience in the nonwovens industry, we design converting lines that focus on your uptime, quality and safety requirements. Our complete project support spans concept development, FAT, installation, operator training and maintenance. Where required, we provide retrofits to upgrade installed systems and data tools to track improvements over time.
