A unique experience into the tissue converting industry
For over 30 years now, Hannecard Rollin has been supplying a unique range of rolls and sleeves coverings that bring the best performances, both in terms of production efficiency and finished goods enhancement.
By combining a unique know-how on both polymer and customer applications, we offer coverings for embossing, gluing and marrying rollers that make converting lines running faster and longer, without compromising on the final output requirements.
Nip pressure optimization
The pressure in the nip is the force which deforms the paper in the embossing process or pushes the glue through the plies (paper layers) in the laminating process. At equal load, Hannecard Rollin covers guarantee a much narrow pressure distribution, offering results that are up to 25% better than the market standard. Conclusion, we need a lesser load to achieve the same goals resulting in less abrasion, longer lifetime of the rollers, lower energy consumption, and lesser stress on the bearings. Furthermore, Hannecard Rollin combines their specific cover properties with an optimized nip calculation. This allows the paper converter to obtain the required caliper, without having to press harder on the embossing roll. As a result, the nip width is restrained, the heat build-up of the covering is limited (enabling the user to run its machine at full speed), and the wearing, ageing and abrasion process are limited. Next to that, limiting the nip footprint will guarantee that the paper tear resistance is not undermined. The final advantage is that the addition of extra paper on every roll is not required and that the process is more stable over a long time.
A strong international focus and a commitment to improving service in local markets
Dynamic simulation of the covering into the nip
Our unique CNPC calculation tool simulates the dynamic behavior of our elastomers in the nip, at a given temperature. The tool allows the optimization of the nip pressure to match the desired tissue product properties. This gives the opportunity to select the best covering solution and optimize the machine settings to get the best results. By combining our expertise with our CNPC tool, we can design the most functional roller coating in terms of cover type and shape (crown) according to the properties of the final product (GSM, caliper, tensile strength, hand-feel, absorbency), the design and details of the embossing pattern and the machine configuration. Taking into account the dynamic properties of our elastomers according to the temperature, our solutions do not only include customized coverings, but also usage recommendations: the nip footprint width, to avoid operators spending time adjusting the rollers and keep their usage on the safest side.
Solutions for all roller coverings of the embossing/laminating units
When aiming to enhance the product caliper, users will obviously push harder and harder on the embossing roll, which will enlarge the nip footprint, enhancing rubber wearing. By combining layers with different properties in terms of elasticity and stiffness, our CNPC tool guarantees that the rubber deflection – i.e. the rubber penetration into the pattern – makes the full usage of the pattern height, without reaching an unnecessary nip wideness.
We also take care about the laminating process. Containing the nip width is of paramount importance to avoid flattening the paper and undermining its caliper. However, it is also necessary to dry the glue, therefor monitoring the time through the nip is needed. Our CNPC tool will deliver outstanding results to grant an optimal lamination. Finally, our unique approach combined with our smart countroll® technology (roller management and monitoring system) helps converters to give added value to their final products and maximizing their production efficiency, triggering hard savings and cost avoidance.
