In the growing market for paper-based packaging, efficiency and productivity are critical factors for manufacturers. As demand for paper bags and e-commerce mailer bags continues to rise, production facilities must find ways to optimize their processes while reducing material waste and minimizing downtime.
Recognizing these industry needs, Contiweb and GARANT MASCHINEN have formed a strong partnership to deliver innovative solutions for paper bag production. By integrating Contiweb CP-N Non-Stop Unwinders into GARANT MASCHINEN’s production lines, production does not need to stop during a (paper) reel change. After all, production time is money!
A strong partnership built on innovation
The collaboration between Contiweb and GARANT MASCHINEN began in 2020 with a major project that saw GARANT acquire nine Contiweb non-stop unwinders for GARANT’s customers.
"Since the start of our partnership with Contiweb, we have built a strong and trusted business relationship," says Dirk Vennemeyer, Head of Purchasing at GARANT MASCHINEN. "Contiweb’s equipment integrates seamlessly into our production lines and help our customers achieve optimal machine performance. While the systems are positioned in the higher price segment, they offer proven quality and reliable performance in return.”
This partnership is not only about technology—it’s about creating long-term value for manufacturers by delivering solutions that increase uptime, enhance operator ergonomics, and improve overall production economics.
Non-stop unwinding increases production output by up to 30%
For manufacturers of paper bags and e-commerce mailer bags, efficient reel changes are key to maintaining smooth production. While manual reel changes remain a flexible and widely used solution, automatic non-stop reel changing with Contiweb’s auto-splicers offers an additional way to boost productivity. By eliminating stoppages during reel changes, Contiweb’s technology maximizes output, reduces material waste, and enhances overall efficiency—especially in high-speed, long-run production environments.
The benefits of Contiweb’s auto-splicer technology:
- Maximized output – Automatic reel changes - regardless of web width or reel diameter - eliminate downtime and boost production output by up to 30%.
- Material savings – Accurate splicing, easy splice preparation, and efficient use of rest reels minimize paper waste.
- Consistent and reliable splice quality – Machine-controlled splicing ensures precise and secure joins, reducing the risk of web breaks.
- Operator friendliness and ergonomics – Reduces physical strain and simplifies production line management—an important benefit in times of labor shortages.
- Efficient reel transport systems – Integrated reel transport solutions streamline reel handling and logistics within the production facility.
Improved ergonomics for operator wellbeing
The integration of Contiweb’s auto-splicer system not only boosts production efficiency but also enhances operator ergonomics by reducing physical strain. The use of Contiweb equipment simplifies reel handling and eliminates the need for operators to manually insert heavy core shafts, which can weigh over 30 kg. This makes it easier for operators to manage reels, minimizing the risk of strain and injuries.
Pim Cornelissen, Product Manager at Contiweb, explains, "Ergonomics is a key focus in the design of our auto-splicer technology. By minimizing the physical effort required to handle heavy paper reels, the system creates a healthier and safer working environment while also improving operational efficiency. Combined with increased production output, the payback period of the CP-N Non-Stop Unwinder is highly attractive."
Full integration of GARANT paper bag machines with Contiweb auto splicers
Contiweb auto-splicers are compatible with all GARANT paper bag machine lines, but they are especially beneficial for the TRIUMPH 5-F6, a high-performance system designed for medium- to large-format block-bottom bags. Equipped with servo technology, the TRIUMPH 5-F6 enables fast changeovers and reduced setup times, allowing manufacturers to easily switch between bag formats. When combined with a Contiweb Auto-Splicer, it ensures greater production continuity and cost efficiency.
Additionally, Contiweb auto-splicers excel in applications with long production cycles, such as shipping and return mailer bags produced with the MATADOR e.BAG in continuous 24/7 operations.
"Integrating Contiweb’s auto-splicers into our paper bag production machines allows our customers to make their production processes more efficient and profitable," says Marc Dettmer, Product Manager at GARANT MASCHINEN. "The combination of our proven machine quality and Contiweb’s innovative technology provides a future-proof solution for the packaging industry."
