Continuous production without interruption

In high-volume production environments, such as paper bags, food packaging, e-commerce envelopes, and protective packaging, efficiency and productivity are critical to achieving the lowest cost per product. When wide reels of paper, paperboard, cardboard, films, or foils must be unwound to produce semi-finished or finished products, significant productivity gains can often be achieved by automating the reel-changing process—especially in systems with multiple winders, where multiple webs are combined to manufacture multi-layered products, such as industrial bags.
 
Using a single unwinder, manually changing a reel when it is depleted typically requires stopping production for at least 15 minutes. This can result in up to a 25% loss in productivity and prevents limited workforce resources from focusing on higher-value tasks. When multiple winders are involved in a single production process, the downtime can be even more significant.
Automated solutions, like the Contiweb CP-N Non-Stop Unwinder, address these challenges by unlocking new levels of efficiency.

Increased cost-effectiveness and optimized resource allocation

Contiweb auto-splicers significantly reduce downtime during reel changes, enabling continuous production and lowering the cost per unit. By utilizing production time more effectively, manufacturers can minimize operational costs and allocate resources more efficiently.

Beyond reducing delays, automated splicing systems also address a pressing issue faced by many industries: labor shortages. By automating the labor-intensive process of manual reel handling, Contiweb’s solutions reduce the reliance on larger workforces. This ensures high productivity even in environments where skilled labor is limited.

Automation not only lowers labor costs but also allows employees to focus on high-value tasks, such as quality control, process optimization, and equipment monitoring. This shift improves resource utilization and enhances employee satisfaction by reducing repetitive and physically demanding tasks.

Improved ergonomics for workforce wellbeing

In addition to enhancing operational efficiency, Contiweb auto-splicers promote workplace ergonomics by alleviating physical strain on workers. The Contiweb CP-N Non-Stop Unwinder is equipped with core chucks that eliminate the need for manual lifting of heavy paper reels or core shafts—tasks that can exceed 30 kg. This ergonomic advantage significantly reduces the risk of injuries and physical stress, fostering a safer and healthier work environment.

By prioritizing employee well-being, Contiweb not only boosts productivity but also contributes to long-term workforce health and morale. This combination of efficiency and care makes Contiweb non-stop auto-splicers a preferred choice for manufacturers seeking sustainable and ergonomic production solutions.

Zero-speed splicing

The CP-N works as a horizontal zero-speed compensator splicer, but with fully automatic splicing as well as integrated infeed as standard.

The proven Contiweb zero-speed festoon design brings the running web and the new web to a halt during the splice cycle while the press is fed from the integrated festoon.

Performing the splice at zero speed minimizes all dynamic forces on the web. The operation is therefore very forgiving of variations in splice preparation, such as operator skills and web quality. A lap splice is standard, and the CP-N can optionally perform one or two-sided butt splices.

The splice can be made at all reel diameters, and the zero speed principle minimizes all dynamic forces on the web with every splice. That offers maximum flexibility for changing substrate or web width easily, including the smallest rest reels.
