The main task of a dryer fabric is to transfer the paper web from the press section to the pope reel through
the challenging (hot and humid) paper machine hood environment. A dryer fabric must also act as a drive
for otherwise undriven rolls and cylinders.
Although paper machine speeds are increasing all the time, the average lifetime of a dryer fabric is also
increasing. This means several million extra laps over a dryer fabric's running lifetime.
The runnability challenges set by higher paper
machine speeds and modern, more effective sheet
stabilizers have doubled the running tension of dryer fa
brics. Due to the high tension, the fabric's wear
resistance and strength - especially seam strength - at the end of the planned running time are very
important.
