The HDU Guide controls the run of the clothing in the wire, press and dryer sections. Adherence to prescribed maintenance and repair intervals ensures flawless functioning.
The HDU Guide has to be checked at regular intervals and if necessary, the HDU Guide must be serviced in accordance with the operating instructions and list of lubrication points. Every four weeks the pendulum sensor, fabric-guiding system and piston seal should be checked for smooth running and leak-tightness. The pendulum sensor should be overhauled every 12 months or replaced if necessary. In addition, servo-cylinders and replacement and wear parts have to be replaced every 10 years.
HDU Guide units are used in the wire, press and dryer sections. Runnability is increased by their flawless functioning, and reliable directional stability of the clothing leads to improved paper quality
