Voith upgrades DuoShake shaking unit with new digital functions

July 24, 2019  By P&PC Staff

July 24, 2019 – Voith has debuted the DuoShake DG (Digital Generation), an upgrade on the control and automation functions of the DuoShake shaking unit for optimum fibre orientation during sheet formation.

The company says the new features significantly improve process reliability and machine availability.

The system optimizes fibre orientation through high-frequency shaking of the breast roll, which results in excellent sheet formation of all paper grades and a low tensile strength ratio. 


All relevant operating parameters can now be entered on site via a fixed operator panel or optional use of mobile devices such as tablets or smartphones. For transparency, a cockpit interface provides users with a real-time display of all main parameters, e.g. availability, stroke accuracy and drive frequency.

Important information – for example on hydrostatic pressure as well as air, oil and motor temperature – is presented as an easy-to-see traffic light system. A customizable notification system for warning messages allows for fast response times if needed.

DuoShake DG records actual operating times, with real-time data on maintenance intervals and service life of the most important machine components. If maintenance becomes necessary, the shutdown can be planned and scheduled to be as efficient as possible.

DuoShake DG also features a trend function for identifying and analyzing faults. In the event of faulty operation, an instantaneous evaluation allows for immediate intervention. With the help of a context analysis designed for a longer period of time, processes can also be systematically optimized.

As an optional service from Voith, an interface can be used to provide a connection between DuoShake DG and the Voith digital platform OnCumulus – a scalable, flexible and expandable data hub for the Industrial Internet of Things (IIoT). The transmission of data and trends to Voith and an analysis and tweaking of the operating parameters by Voith experts can result in increased availability.
