Pinions and gear wheel segments for drying cylinder drives
reduce cost, noise and downtime
For many years gear wheel drives where used for paper and
board machines with wheels in casted iron but increased machine
speeds caused vibration and noise. Gear wheels in casted iron
could get damaged in case any object gets in between two gear
wheels and to change a complete gear wheel was a huge effort
for the maintenance team, extremly expensive and caused several
hours machine downtime.

Wefapress has developed the hydrolyse resistant
Nylatec360 material for the tough application inside the drying
hood. It is resilient to the high temperature, moisture and absorbs
also demanding mechanical forces after many years of application.
Nylatec360 cause running smoothness without vibration and noise,
there is no lubrication grease needed what result in a clean drive
side of the paper and board machines. Another huge advantage is
the easy change of the gear wheel segments while the metal rim
can stay installed. This means the machine downtime get reduced
from several hours to just a few minutes.
The competent paper technology experts from Wefapress
analyse each customer situation and provide individual solutions
for each application. Service technicians support paper mills also
worldwide during regular maintenance work to ensure long-term
success.
