In-line vs off-line converting: reliable solutions for nonwovens and technical textiles

Since the 1970s, CAMPEN Machinery A/S has delivered reliable, robust converting solutions for nonwovens and technical textiles. When considering in-line vs off-line converting, we focus on delivering the best fit for your products, processes, and budget. Our engineering-driven approach ensures efficient, quality-oriented results through close cooperation from the first idea to long-term service support.

Key factors when choosing between in-line and off-line converting

Your decision between in-line vs off-line converting depends on several factors: product mix, required uptime, and specific quality demands. In an in-line setup, processes such as winding, slitting, and rewinding are fully integrated into the main production line. Off-line converting, on the other hand, utilizes separate equipment, allowing for flexible post-production processes. Understanding these differences helps you achieve optimal efficiency, minimal waste, and low lead times.

Advantages of in-line converting for continuous production

• Suitable for stable, high-volume output where uninterrupted production is needed and changeovers are rare.
• Minimised material handling reduces risk of damage to sensitive fabrics, enhancing first-pass yield and product quality.
• Integrated controls allow precise tension management, resulting in consistent roll quality at targeted line speeds.
• Inline inspection and automated roll changes maximise uptime, cut waste, and lower operator intervention.

Benefits of off-line converting for flexibility

• Ideal for frequent format changes and short run lengths, supporting rapid changeovers and diverse orders.
• Handles a wide range of fabric types, including technical textiles and delicate nonwovens, without affecting main process uptime.
• Dedicated slitting and rewinding lines ensure robust quality control for strict requirements.
• Supports order-based planning and reduces work-in-progress, especially for varied SKU or smaller batch production.

We work with you to assess roll dimensions, material types, and line speeds to recommend the right process. Choosing in-line vs off-line converting is a data-driven decision, tailored for your operating teams and business requirements.

How in-line converting improves efficiency

CAMPEN’s in-line converting systems connect directly with upstream manufacturing. Every element, from web control to roll handling, is engineered for your process to ensure stable and reliable production outcomes.

• Closed-loop tension control reduces waste and safeguards coatings and web edges, improving product consistency.
• Accurate web guiding lowers edge trim losses and delivers clean, consistent roll profiles.
• Automatic roll change and splicing minimize downtime and increase safety by limiting manual roll handling.
• Inline inspection technology identifies defects early, reducing rework and improving overall quality.
• Compact, easy-to-operate systems ensure convenient access for your staff and optimise floor space.

We customise slitting, winding, and rewinding to suit each customer’s roll diameters and build needs. Our drive technology and tension management ensure top quality from core to full roll. Control systems are integrated seamlessly with PLC, MES, and existing safety infrastructure, giving you reliable production and a single support point throughout the equipment lifetime.

Off-line converting for flexible production and quality

Our off-line converting lines for nonwoven and technical textiles provide the versatility required in modern production. These systems accommodate variable widths, core sizes, and material types using simple, repeatable settings—ideal for trial runs, varied SKUs, and processing sensitive substrates.

• Modular slitting and rewinding designs let you add new products or upgrade processes without heavy investment.
• Recipe-driven set-ups enable your operators to produce consistent quality and reduce material waste during changeovers.
• Advanced inspection and defect mapping ensure compliance for demanding or regulated applications.
• Ergonomic designs improve operator safety and minimise manual lifting.
• Energy-saving drives and standby options help reduce operational costs and environmental impact.

Available slitting technologies—shear, crush, or razor—match your specific fabric and edge demands. Unwind and rewind functions are engineered for precise torque control, yielding optimal roll structures. Add-ons like web cleaning, splice tables, roll labelling, and integrated data logging offer further customisation. With CAMPEN’s reliable spare parts and ongoing support, your line delivers consistent performance for years.

Your project roadmap: from initial study to ongoing service

We start with a technical assessment tailored to your product mix, speed targets, roll sizes, and operational aims. Based on these findings, we recommend either in-line, off-line, or hybrid converting systems for maximum efficiency and reliability.

• Pilot trials and factory tests validate your quality benchmarks and reduce the risk during ramp-up.
• Operator training and clear documentation ensure safe, easy operation for your team.
• Remote and on-site support, upgrades, and retrofits help secure your investment and sustain peak output.
• Global service ensures you achieve high OEE and safety wherever you manufacture.

Our focus is on measurable gains in efficiency, safety, and quality across every project—whether upgrading existing lines or installing new capacity.
