Unlocking potential

    More capacity, better quality and improved safety

    Voith upgrade solutions allow you to optimize your winder to address the specific goals and situations you require.

    We have developed a wide range of upgrades to optimize the performance of your winder, including automation and drive upgrades. Our solutions offer more capacity, better quality and improved personnel safety. These upgrades are suitable for different winder models.

    Capacity upgrades

      Higher speed, faster roll change

      Smart solutions with great effects: With Voith capacity upgrades, maximum production speeds can be achieved and change times for parent and finished rolls  can be accomplished significantly faster.

      SmoothRun – Increases capacity due to lower vibrations

      For higher production speeds and better winding results

      During the winding process, vibrations can occur in winders processing paper with high friction values. With the hydro-pneumatic damping SmoothRun bearings, these vibrations are greatly minimized, and the machine can be consistently operated at high production speeds. This not only achieves a significant increase in capacity but also avoids undesirable winding defects. Thanks to an optimized retrofit concept, conversion to SmoothRun is easy without major modifications to the existing machine.

      Advantages

      • Significant capacity increase with higher production speeds
      • Better winding results by avoiding winding defects
      • Reduced mechanical stress on the winder minimizes maintenance requirements
      • Easy retrofitting of existing winders

      Following commissioning of the new bearing system we were able to reduce vibrations for all paper grades and increase speeds. (…) While further enhancements together with Voith are being made, the winder can keep pace with the production of the PM 5.

      • Significantly faster set change
      • Solutions available for all popular basis weights
      • Flexibility through hot-melt or tape adhesive application

      Quality upgrades

        Customized solutions for better precision, quality and improved safety

        Voith quality upgrades allow you to optimize the production process according to your requirements. Solutions are available for the most diverse process steps, for example, automatic slitter positioning for better precision and a wide range of roll covers for perfect winding results.

        TruSet – High-precision, automatic slitter positioning

        For a faster pattern change, higher precision and less waste

        Changing patterns can be easy and clean. In the winder, TruSet automatically positions all slitters with exact precision. The production capacity is increased and the reject rate due to incorrect patterns is reduced. Maintenance requirements are also reduced since recalibration of the slitter position is not required after band sharpening or belt replacement.

        Advantages

        • Highest cut precision (+/- 0.25 mm | +/- 0.01 in)
        • Lower susceptibility to errors
        • Higher production capacity

        Removing dust – Less dust for better quality

        A clean slitter section for reduced cleaning effort

        A fine dust is produced during the slitting process and accumulates continuously in the winder and in the environment. The fine dust affects the quality of the finished rolls and, in the long run, the wear of moving machine parts. This creates the need for continuous, demanding cleaning and increases maintenance costs. Voith’s dust extraction system puts an end to the dust problem by extracting it directly from the slitters during the cutting process. The result is significantly less dust ingress into finished rolls, machines and the environment overall. The papermaker benefits from higher quality finished rolls, as well as significantly reduced manual cleaning and maintenance cost.

        Advantages

        • Automatic dust extraction at the slitters
        • Reduced wear of the machine's moving parts
        • Less dust entering into the finished rolls
        • Less dust in the machine and environment
        • Reduced maintenance and cleaning costs

        The Ela family – Customized roll covers for any application

        For better quality and significantly larger finished rolls

        Increasing nip pressure can lead to winding defects as the roll diameter increases, especially for paper grades with sensitive surfaces. The alternative: Using the Ela family of roll covers, the surface of the rolls can be optimally adapted to individual requirements. The coating reduces the nip pressures with deviations in the cross profile and minimizes the entry of air during the winding process. At the same time, the covers improve the grip of the rolls and stabilize the run of the paper web. The Ela family increases the quality of finished rolls and enables the winder to produce significantly larger and heavier finished rolls.

        Advantages

        • Increased winding quality
        • Processing of larger and heavier rolls

        The RollerBar spreader unit –
        Perfect separation even with narrow patterns

        For perfectly separated finished rolls

        A clean and reliable cut separation is essential, especially for narrow patterns. Voith developed the RollerBar spreader unit as the appropriate quality upgrade to mitigate concerns. The RollerBar system consists of narrow roller segments moved via pneumatic cylinders. The segments can be continuously readjusted during operation. The sheet setting of the roller segments can also be individually adjusted for optimum spreading. The improved web travel enables even narrow and difficult patterns to be cut quickly and cleanly at high winding speeds.

        Advantages

        • Cleanly separated finished rolls for narrow patterns and high winding speeds
        • Fewer rejects due to reduced quality issues
        • Improved winding quality

        Safety upgrades

          Mitigating danger, increasing work safety

          Personnel safety during operation and maintenance of winders is top priority. Our smart safety upgrades allow for automation and decreased time for various work and maintenance processes. The upgrade solutions make important contributions to greater safety in the workplace.

          Automatic web threading - Greater safety and higher capacity

          For fast and safe paper web threading

          Manual web threading during a parent roll change is not only time-consuming but also a potential source of errors and a safety risk for personnel. By upgrading to automated web threading, safety can be increased, and the time needed for parent roll changes can be significantly improved. The new paper web is automatically threaded to the new core, so only minor manual intervention and significantly shorter machine stops are necessary. In addition to a clear safety improvement, the automated process results in minimal downtime.

          Advantages

          • Safety through automated process
          • Fast and reliable
          • Increased capacity due to shorter machine stops

          Quick blade change – Shorter downtime and greater safety

          For a quick and safe blade change in a few easy steps

          With conventional systems, it can take several minutes to replace a blade because of the many screw connections. The innovative blade quick-change system is much easier and faster. A simplified blade replacement also reduces the risk of injury and lowers maintenance costs. In addition, production capacity increases due to the shortened machine downtime.

          Advantages

          • Blade replacement without tools in record time
          • Time savings during replacement
          • Greater safety through simple change procedures
