Broad paper grade applications for two-drum compact winder


T


he technology behind Voith’s VariFlex two- drum winder has been reworked and further


developed. Along with simplified operation, special attention has been paid to ensure robust safety technology for the winders, which are up to seven metres wide and have a roll diameter of 2,100mm. In the two-drum concept, the


roll set is wound in a roll bed formed by two winder drums. With the latest VariFlex line, Voith has further developed its VariFlex S, M and L two-drum winders and simplified their control technology.


It is primarily the roll geometry,


the roll arrangement and, if applicable, the covers that are important for the high productivity and consistent quality of the two-drum winder, says Voith. Properly combined,


they ensure high speeds, a reliable web run, good roll geometry and reliable handling of large roll diameters as well. Depending on the requirements and design, production speeds of up to 3,000 m/min are possible


without any problem. The modularly structured


VariFlex was designed for a broad range of applications and due to different roll and cover combinations allows configurations for numerous


paper grades. While new paper machines from Voith are already delivered with a winder, the new VariFlex was designed in particular for replacements or rebuilds on existing machines which requires only very short shutdown and optimisation times. Since VariFlex is directly


delivered with all drives included, customers benefit from fewer interfaces and especially short commissioning and system optimisation timeframes. The specifically developed elastic covers for the winder drums, ElaGrip and ElaCare, ensure flawless winding quality even for demanding paper grades. Together with the VariPlus and VariTop single-drum winders, VariFlex covers the entire range of winders for all paper grades and characteristics. More information from Voith at www.voith.com/paper


First customers impressed by QCS software platform


A common software platform that integrates Voith Paper’s future QCS product portfolio has been launched. With ComCore, it is said to be


even easier to deliver solutions that are exactly coordinated with the needs of paper producers. Already in use on some 15 paper machines worldwide, in various paper grades, it is said to be satisfying and impressing customers with its benefits. The various Voith QCS products such as OnQ ModuleJet, OnQ FormingSens and the Voith LSC

Scanner are consolidated in ComCore. It therefore offers, with just one click, a way to perform all necessary interventions and call up all necessary information about the various components and applications of the quality control system. Other products can be integrated at any time by expansion of the software modules. The start-up times are thus shortened. The uniform platform architecture also reduces the training needed for service personnel.


In developing ComCore, Voith


relied on established standards in the industry such as OPC for communication and combined them with innovative technology such as HTML5. As it is operated with a web user interface ComCore is as easy and intuitive to use as possible. ComCore can also be operated with commercially available tablet PCs, which increases the mobility and flexibility of employees. Time-consuming installation is not an issue with these operating stations, as the ComCore user


interface is simply called up via Internet Explorer. If work is undertaken directly on a part of the paper machine, the corresponding personnel thus keep all other machine settings in view on their mobile tablet PCs and can better react to changes. Thus ComCore additionally provides a clear safety advantage for the individual employee. For any further questions on automation, Voith’s worldwide service network is always available for customers.
