Jul. 4, 2017 – With the addition of AiroGuide to its product range, Voith is offering a guide roll cover in what the company describes as a modern fibre, that is very light but durable, composite material suitable for all paper machines.

Endurance tests in the field, explains Voith, showed that the new guide roll covers were able to increase the replacement intervals also in positions suffered from high wear using standard rubber covers. The company continues to explain that the high wear resistance of the cover helps to ensure that the fabric wear profile stays straighter for a longer period, because the roll wear will not be transferred to a higher fabric wear.


Voith explains, that like all of composite roll covers, AiroGuide covers can also be repaired in the case of minor damage, avoiding the need for a complete replacement. The high wear resistance of the cover helps to ensure that the fabric wear profile stays straighter for a longer period and the roll wear will not be transferred to a higher fabric wear as a result of the speed differences.

The purpose of guide rolls is to guide or redirect wires, felts or paper in a paper machine. AiroGuide is a highly versatile modular cover concept that can be used for every guide roll position in every section of the paper machine: wire guide rolls, felt guide rolls, paper guide rolls.

AiroGuide roll covers can be adapted to any machine and matched with other Voith products. Voith explains the specification of the roll cover will always be optimized to the requirements of the application in terms of cover thickness, temperature resistance, and electrical conductivity.
