Product Management Tissue.
The inventive company from south Germany with a long history working in close cooperation with manufacturers of additives, has developed a precision system based on a proven technology: the non-contact fluid application system. This provides numerous benefits for the tissue industry. Your Benefits:
- Free in embossing design
- No knurling necessary
- Process reliability
- Precision and reproducibility
- Less strain on the tissue
- High productivity and economy
- Raise in print quality.
THE WEKO SOLUTION
Based on rotating, spraying discs, a uniform stream of finest micro-droplets is generated at a high speed to accurately give the tissue its individual properties. “The application volume can be controlled quickly and precise for reproducible results. Because less is sometimes more – it is the effect that counts” – emphasizes Carolin Russ, Product Manager at WEKO.
The mechanical tissue strain does not come into play with the WEKO-Fluid-Application-System (WFA). There is no contact with the tissue and therefore it is handled extremely carefull. The rotation of the discs create a 360° spray circle from which a part is used that meets the tissue. The remaining part of the spray circle is kept in the chambers of the rotor carrier and is circulated to the supply unit where it is re-used. By continuous filtering the liquid, contamination of the application bath does not appear. As a special option for this industry WEKO thought about a solution to prevent the tissue web from sticking and so breaking if the machine is being stopped.
Our encapsulated version WEKO-ProTec provides the rotor carrier with an enclosure which can be connected to an extraction system. Contamination of the working environment is avoided and thus safety generated.
HOW DOES IT WORK?
Ply bonding. Ply bonding with WEKO means bonding the single tissue layers applying a defined small amount of liquid glue. The combination of several plies during embossing forms the multi-layer tissue. For WEKO`s rotor spray application water-based glue is suitable. Its fine dispersed micro droplets are distributed even and work perfect on sensitive surfaces without any material strain.
Teamwork and innovation are our keys to success
Water bonding. Water bonding is a booster for the ply bonding process. With three or more plies an adhesion is possible without extra knurling. Therefore the embossing design is very flexible and cost saving since no extra knurling tool is required. By spraying a defined amount of water, the layer adhesion is massively improved, as the water increases the penetration of the before applied glue in every single layer. Also the swelling properties of the fibers allow improvements of the tissue in dimension, bulkiness and volume. Your process reliability is increasing since the system works very continuously.
Experience the “Innovation at work”. Together with an international partner, we are currently working on a pilot lane where you can test your ideas outside of the running production. Contact us for more information about the improvement of your multi-layer tissue.
