A double doctor system provides the extra performance of two independently adjustable doctor blades within one unit and is ideal for aiding in water removal from surfaces.
Couch Roll Double Doctor Blade
The couch roll double doctor blade is dedicated to effectively removing surface water and debris build-up on the couch roll. The couch roll double doctor blade first removes the initial layer of surface water, creating a vacuum on the underside of the blade. This vacuum extracts the debris and fillers from the couch roll holes, bringing them to the surface. The second doctor then removes the remaining surface water, fines and fillers, sending a clean roll back to the nip.
Suction Pressure Roll Double Doctor Blade
The suction pressure roll double doctor blade is specially designed for dewatering suction pressure rolls in tissue making applications.
