OptiPress Center
Center roll based press section is a reliable, well-known concept combining close to 40 years of pressing technology experience with modern shoe press technology. A shoe press replaces a roll just before the first open draw. The resulting boost in dryness thus fully benefits web runnability in the open draw.

Runnability Systems
Runnability systems stabilize the run of the web and secure tail threading in the dryer section. In practice, the equipment helps to hold the web in contact with the fabric by creating underpressure on the other side of the fabric. The underpressure is created by blowing, suction, or a combination of both.
