Kraft Liner for Packaging Food and Fruit
MWV Rigesa starts up new PM 4
2013-11-22 - In 2012, MWV Rigesa started up kraft liner production on its new PM 4. The company, a subsidiary of MeadWestvaco Corporation MWV, produces 300,000 metric tons of kraft liner per year on this machine for use in the company’s packaging converting operations throughout Brazil. The producer’s supplier selection was based upon the Process Line Package in which Voith took the responsibility for nearly the complete project.
With the PM 4, MWV Rigesa produces high quality kraft liner using the latest Voith technologies. The installed MasterJet Pro, for example, is a headbox that combines optimum paper quality with maximum energy efficiency. Its innovative dilution technology feeds the dilution water directly into the stilling chamber, which provides for a very
even distribution. This dosing method results in a high accuracy of the control response in the web, which is improved by over 50% compared with conventional systems.
The dilution system is controlled by the OnQ ModuleJet CD actuators. This mechatronic module consists of metering element, valve, linear drive unit and control. It is perfectly tailored to the dilution principle so that MWV Rigesa benefits from an integrated system that features uniform profiles, better paper quality, lower energy consumption and reduced operating costs.
Other technical advantages of the PM 4 arise from the installed Tandem NipcoFlex press, which is mainly used for fast and efficient machines. Two shoe presses in a row ensure a high dewatering capacity after press allowing high speed. The dryer section has a single tier configuration in the beginning to stabilize the sheet and to increase runability.
Benefits from a one-stop supplier.The final and probably most important reason for the selection of Voith as preferred supplier is the company’s Process Line Package. According to the PLP approach, Voith takes full responsibility for a new project. As a general contractor and expert on the entire paper manufacturing process, Voith ensures that the machine goes into operation safely at the guaranteed start-up time.
At MWV Rigesa, Voith took sole responsibility for the whole paper machine including every section of the entire process line, like piping, pumps, turbines, vacuum system, electrification, valves. Only vacuum pumps, the electric package, the OCC plant and all civil works were the customer’s responsibilities. Therefore, the paper producer had only one contact and one interface for the major part of the scope of supply. With the PLP, the entire project cost was established at the beginning of the cooperation, which provided full transparency to the customer.
