The range of use of board
As the base material for a range of high-quality packaging options, cardboard is omnipresent. As a leading manufacturer, our board machines offer excellent formation, maximum dry contents, optimum web guiding and superlative runnability.
Board plays an especially large role as packaging in the modern world. Beverages, shoes, alcoholic drinks, toys, cigarettes and cosmetics – they are all packaged in various grades of board, and they all have different requirements for the board’s raw material. The wide range of products made of cardboard and the many ways it can be manufactured, combined and used are greater today than ever before.
The fitting board for every application
It protects its contents, such as medicines and foodstuffs, from the effects of weather, dirt and damage. Board is used for storage and also performs a selling and advertising function by drawing attention to its content. In production, board is primarily distinguished from packaging paper by the number of plies, the raw materials used and the finishing processes such as coating and calendering. Due to its function and characteristics, board is usually produced from fresh fibers or from a mixture of secondary fibers, pulp or mechanical wood pulp. But there are also grades that are produced from up to 100% recovered paper.
We know the challenges in board production
Voith is a leading manufacturer of board machines and offers solutions to meet the stringent demands of board production, such as excellent formation, maximum dry content with optimum sheet guiding and the highest level of machine runability. Our solutions take account of the entire manufacturing process from pulp production through stock preparation to roll packaging. We work sustainably and continuously on improving the ecologically and economically efficient processes and machines for board production.
Engineered for success
Voith builds new XcelLine board machine for Bohui Paper Group
In February 2017 Bohui Paper Group contracted Voith to supply a new board machine. The BM 4 will be built at Dafeng in the Chinese province Jiangsu and following completion will be one of the largest board machines in the world. Voith will supply the complete XcelLine process line from wet end process to winder. This reduces the number of interfaces for the customer to a minimum and provides cost transparency for the entire project.
Infinity ToughLine: Time savings of 50 percent when changing fabrics
The Infinity ToughLine press fabric maintains its consistently high void volume even when exposed to high line load and substantial degree of wear. A constant water flow guarantees consistent performance over the entire life of the fabric.

Successful rebuild of R.D.M.'s BM 3 in Arnsberg, Germany
R.D.M. could reduce costs and improve quality and productivity on their BM 3 after completion of the rebuild project with Voith. Increased production speeds and the decreasing quality of the waste paper used as raw material made the rebuild necessary to produce as cost-efficient as possible. Together with Voith, R.D.M. Arnsberg developed the cost-efficient rebuild concept to set‐up production for the future which was realized with this machine upgrade.

Depending on the purpose for which a paper is used, its surface must have certain properties – especially smoothness and gloss. These properties are imparted to the paper by calenders. Calenders are machines with up to 15 rolls arranged one above the other, which are run together under pressure and then form closed nips.
The EcoCal Hard calender is for online calibration of the paper web and gives the paper a constantly precise thickness due to its hard nip between rolls. The smoothness can also be increased.read more
